Creating Effective Information Security Policies

We haven’t the time to take our time.

Eugene Ionesco, 1912–1994

When organizations first recognize that they need to ensure that the information

assets of the organization are adequately protected, this usually results in asking

the question, “What applicable policies are in place?” There may be some human

resource policies that might apply or corporate policies noted in the ethics and

compliance code of conduct, however, these are normally insufficient to address

the breadth of the information security needs. The next step is for the organiza-

tion to embark upon the time-consuming task of developing information security

policies.

Why Information Security Policies Are Important

To the seasoned information security practitioner, asking why information secu-

rity policies are important may seem like a question with an obvious answer. The

question is not so obvious to the end users of the organization, as many of them

may feel that if everyone applies common sense, there is no need for them to read

and sign off on voluminous sets of policies. The reality is that each person has a

different interpretation of what is common sense. For example, leaving a scruffy

old backpack containing books in a car may seem like a reasonable act to one em-

ployee who wonders why would anyone want to steal a bag full of books. Another

employee might think that because of the condition of the backpack, no one

would want to steal it. Another might think that their car is parked in broad day-

light in a heavily traveled area, which would make the risk of stealing it quite low.

Another employee may think that the car alarm would be a sufficient deterrent

from anyone wanting to go through the trouble of stealing the backpack.

Then along comes the information security officer, whose job it is to evaluate

the course of action that will provide reasonable security. The security officer

knows the stories of break-ins all too well, and knows that criminals do not know

for sure what is in the backpack. The criminal might assume that there is a laptop,

money, or credit cards that could be sold for a nominal amount to buy drugs, alco-

hol, or support rudimentary living expenses. Thus, the opportunity and motiva-

tion presents an unacceptable risk that must be mitigated. The organization can-

not afford to leave these individual decisions up to the common sense internal

barometer of thousands of employees. The organization must set forth advice or a

baseline of what behavior is expected for each employee, and not leave this up to

individual discretion. This advice, and expected behavior, is manifested through a

set of information security policies. The policies form the cornerstone of the infor-

mation security program and are representations of management’s intention that

are needed to control the information security assets.

Avoiding Shelfware

4/9/23, 9:12 PM Chapter 6 Creating Effective Information Security Policies | Information Security Governance Simplified

Although information security policies are very important, they can easily be-

come shelfware if their development, management, and distribution are not han-

dled appropriately. Countless security departments have filled binders full of poli-

cies over the years that remain unread and require frequent dusting. As the

Intranet-based environments started to take hold in the mid-’90s, these environ-

ments moved from paper-based shelfware to electronic-based shelfware. The se-

curity department may have had a large project to develop the information secu-

rity policies, place them on the Intranet, and then they were “done.” Lengthy,

technical documents with all the technical jargon may have sounded impressive

to the security department, but fail when end users are required to read them be-

cause they are not understandable. Who would read these lengthy documents?

The same individuals that would read the complete car owners manual after pur-

chasing a new car before they put the key into the ignition—in other words, a

very small segment of the population. The security policies should be written in a

language from the user and be brief enough to get the point across without over-

whelming the end user. More detailed descriptions can be placed in standards

documents that the users can read if they need additional information. An organi-

zation security policy beyond 30 to 60 pages is normally much more than would

be required by any medium- to large-sized organization. Beyond that level, the

policies are likely to go unread.

Electronic Policy Distribution

To avoid shelfware in electronic policies, they need to be kept (1) brief, (2) up-

dated, and (3) relevant. Web-based policies should each be no more than two on-

line pages to get the point across as to what is expected (Fitzgerald, 2004).

Resumes are kept to two pages for a reason—people stop reading them if they

4/9/23, 9:12 PM Chapter 6 Creating Effective Information Security Policies | Information Security Governance Simplified

https://learning.oreilly.com/library/view/information-security-governance/9781439811658/017-9781466551282-006.xhtml 4/30

have not received what is needed within the first two pages. Daily online articles

on sites such as Yahoo and USA Today are no more than two pages, as the reader

may lose interest after that.

The policies need to be updated at least annually to ensure that the manage-

ment direction is still desired. As employees comes across a policy that was last

updated 4 years ago, they may make the conclusion on their own that the policy

no longer applies. The organization may have gone through a merger, and the

conflicting policies may exist for the two organizations or worse yet, if the policies

have never been integrated, the employees of the acquired company may make

the erroneous assumption that they should still follow their old company policies

and may not be aware of the new acquiring company policies.

Policies need to maintain their relevancy to remain effective. For example, if an

organization has not addressed the use of social media in their policies, the man-

agement and end users will have to rely on the existing policies to determine

whether social media is acceptable. Or, suppose an employee just purchased an

iPad tablet computer, but the policy indicates that no personal desktop or laptop

computers may be used within the company. Should the iPad be allowed?

Technically, according to the policy, the iPad “tablet” computer has not been ad-

dressed, and the associate may leave it to an interpretation more favorable to the

employee as to whether to use the device.

Policies posted online should always ensure that the revision history is pro-

vided as well, so that users can see what changes were made to the documents

and also determine if they are looking at the correct version. Even with many

companies moving toward green, environmental-friendly initiatives to reduce

https://learning.oreilly.com/library/view/information-security-governance/9781439811658/017-9781466551282-006.xhtml 5/30

wasteful printing and disposal costs, many end users still prefer to have a paper

document that can be referenced when needed. The revision update date and his-

tory help ensure that the correct document is being utilized.

Several security vendors have products that will provide an electronic distribu-

tion of security policies and also provide a mechanism for end users to confirm

that they have read, accepted, and understood the policy contents. The results are

then recorded in a database that can be queried as needed. This information be-

comes very useful during incident investigations, terminations, and lawsuits

where the company wants to demonstrate that the employee had clear knowledge

of the policy and chose to violate it against the corporate policy.

Canned Security Policies

Consulting organizations have sets of policy templates that are used to jumpstart

a client’s need for information security policies. These are then tailored to the

needs of the organization. This process may be more effective than writing the in-

formation security policies from scratch, as long as the policies meet the compli-

ance, laws, regulations, and desires of the organization. It is not unusual to see

where an organization has implemented a copied policy verbatim, sometimes

even forgetting to change the company name on the template. During the 2010 BP

oil spill, it was revealed that the business continuity/disaster recovery documents

from several major oil companies appeared to have used the same templates for

their disaster recovery plans (Gupta, 2010). Although developing the complete in-

formation security policy is beyond the scope of this book, there are several infor-

mation security books available with sample polices that can be used to jumpstart

the development. Two very good sources are Information Security Policies and

Procedures—A Practitioner’s Reference (Peltier, 2007) and Information Security

Policies Made Easy by Information Shield (Wood, 2009). Both of these sources con-

tain valuable information at a fraction of the cost of a security consultant for one

day.

Policies, Standards, Guidelines Definitions

Organizations typically do not have a consistent understanding as to what a “pol-

icy” is. This seems like such a simple concept, so why the difficulty? The reason is

not the lack of understanding that a policy is meant to govern the behavior within

the organization. The reason for the confusion has more to do with the fact that in

the interest of saving time, organizations will combine policies, procedures,

guidelines, and standards into one document and call it the policy. This is not re-

ally a time saver because it makes it more difficult by introducing inflexibility

into the policy each time the policy needs to change. This is similar to denormaliz-

ing a database structure to make the performance more efficient, when in fact it

becomes harder to add new data elements to a particular table without redesign-

ing the table. The policies and procedures end up getting fused together, and so

when the procedure changes, the policy document by default is changing as well

when the policy does not need to change. Or, the employees begin to think that

the procedure is the only way the policy can be implemented, when there may be

multiple procedures across the organization that are implemented to comply with

the policy. For example, an organization might have a policy that all systems need

a full backup weekly and they need to be maintained off site. The data center may

have a procedure that ensures that tape backups are taken weekly and the tapes

are picked up by a vendor and transported to the secure off-site storage. The

midrange server infrastructure team may have a procedure to ensure that full

4/9/23, 9:12 PM Chapter 6 Creating Effective Information Security Policies | Information Security Governance Simplified

https://learning.oreilly.com/library/view/information-security-governance/9781439811658/017-9781466551282-006.xhtml 7/30

backups are taken weekly through the online data vaulting process, in addition to

the daily incremental backups at the remote site. The desktop support department

may have a procedure that ensures that company critical information is stored on

network drives, also subject to the weekly online backup process. In this case,

each area has designated local procedures that ensure that they are in compliance

with the higher-level corporate policy.

Policies Are Written at a High Level

Policies should be written at the highest level possible to still be able to communi-

cate the intentions of the company. The higher the level of the policy, the more

likely the policy is able to stand the test of time. Companies do not want to be reis-

suing policies on a frequent basis unless they have to. This involves resources for

development and, more important, the time and expense of each person to reread

the complete policy. Whereas changes in technology, company structure, laws and

regulations, emerging trends, and so forth warrant changes to the security policy,

frequent changes due to minor technology changes are not desired. The reaction

of most users will be, didn’t we just do this? For example, if password standards

are written into the password policy for a primarily Windows-based environ-

ment, what happens when a Unix server for the SQL server data warehouse

project is introduced? Will the password policy need to be redistributed and at-

tested to by thousands of users, when the change impacted only a small number

of users?

Security officers and their teams are charged with the responsibility of creating

the security policies. The policies must be written and communicated at a level

that is understood by the end users of the organization if there is to be any chance

4/9/23, 9:12 PM Chapter 6 Creating Effective Information Security Policies | Information Security Governance Simplified

https://learning.oreilly.com/library/view/information-security-governance/9781439811658/017-9781466551282-006.xhtml 8/30

of compliance. If the policies are poorly written or written at too high of an educa-

tion level (common industry practice is to focus the content for general users at

the sixth-to eighth-grade reading level), the policies will not be understood.

Whereas security officers may be charged with the development of the policies,

the effort is normally a collaborative effort to ensure that the business issues are

addressed. Utilization of an security council, executive oversight committee, or a

subgroup of that committee, depending upon the policy being drafted, is an ap-

proach that considers the business impacts of a security policy decision.

Developing the policies solely within the information technology department and

then distributing the policies without business input is likely to miss important

business considerations. As always, deciding on the appropriate security controls

is a decision of risk by the organization, which ultimately should be decided by

the business leaders. The organization is also more likely to accept security poli-

cies that have been approved and endorsed by the business leaders versus the se-

curity officer or the information technology department.

Once these different documents have been created, the basis for ensuring com-

pliance is established. These deliverables form the basis for organizational com-

pliance with the security policies. The most current versions of the documents

need to be readily accessible by those that are expected to follow them. Many or-

ganizations have placed these documents electronically on their intranets or

shared file folders to facilitate communication of the most current documents.

Placement of these documents plus checklists, forms, and sample documents can

save time for the individual and be an added value provided by the security

department.

Policies

Policies define what at a high level the organization needs to accomplish and

serves as management’s intentions to control the operation of the organization to

meet business objectives. The why should be stated in the form of a policy sum-

mary statement or purpose. If end users understand the why, they are more apt to

follow the policy. As children, we were told what to do by our parents and we just

did it. As we grew older, we challenged those beliefs (as 4- and 5-year-olds and

again as teenagers) and needed to understand the reasoning. The rules had to

make sense to us. Today’s organizations are no different; people need to under-

stand the why before they can really commit.

Security Policy Best Practices

Someone once said, “Writing security policies is like making sausage. You don’t

know want to know what goes into it, but what comes out is pretty good!” Writing

policies does not have to be a mystery, and there are several guidelines for creat-

ing good security policies practiced in the industry.

Clearly define policy creation practice—A clearly defined process for initiating,

creating, reviewing, recommending, approving, and distributing the policies

communicates the responsibilities of all parties necessary and the time expecta-

tions of their participation. This can be accomplished by process flows, swim

lanes, flowcharts, or written documentation.

Write policies to survive 2 to 3 years—Policies are high-level statements of the

objectives of the organization. The underlying methods and technologies to im-

plement the controls to support the policies may change. By including these in

the other related documents (procedures, standards, guidelines, and baselines),

4/9/23, 9:12 PM Chapter 6 Creating Effective Information Security Policies | Information Security Governance Simplified

https://learning.oreilly.com/library/view/information-security-governance/9781439811658/017-9781466551282-006.xhtml 10/30

the policy statements will need less frequent change. This avoids frequent up-

dates and subsequent distribution to the organization.

Use directive wording—Policies represent expectations to be complied with. As

such, statements such as must, will, and shall communicate this requirement

versus using weaker directives such as should, may, or can. This latter type of

language is better reserved for guidelines or areas where there are options.

Avoid technical implementation details—Policies should be written to be tech-

nology independent, as the implemented technology may change over time.

Keep length to a minimum—Policies published online should be limited in

length to two to three pages maximum per policy. The intent for the policies is

for the end user to understand and not to create long documents for the sake of

documentation.

Provide navigation from the policy to the supporting documents—If the imple-

mentation of the policy is placed online, then hyperlinking the procedures,

standards, guidelines, and baselines can be an effective method to ensure that

the appropriate procedures are being followed. Some of the internal security

procedures would not be appropriate for general knowledge, such as the proce-

dure for monitoring intrusions or reviewing log files, and these need to be ac-

cessible by the security department and properly secured from general

distribution.

Thoroughly review before publishing—Proofreading policies by multiple individ-

uals can catch errors that may not be readily seen by the author.

Conduct management review and sign off—Senior management must endorse

the policies if they are to be effectively accepted by all management levels and

subsequently the end users of the organization.

https://learning.oreilly.com/library/view/information-security-governance/9781439811658/017-9781466551282-006.xhtml 11/30

Avoid techno speak—Policies are oriented to communicate to nontechnical

users. Technical jargon is acceptable in technical documentation but not in

high-level security policies.

Review incidents and adjust policies—Review of the security incidents that have

occurred may indicate the need for a new policy, a revision to an existing pol-

icy, or the need to redistribute the current policy to reinforce compliance.

Periodically review policies—A formalized review process provides a mecha-

nism to ensure that the security policies are still in alignment with the business

objectives.

Develop sanctions for noncompliance—Effective policies have consistent sanc-

tion policies to enable action when the policies are not followed. These sanc-

tions may include “disciplinary action up to and including termination.”

Stronger language can also be added for prosecution for serious offenses.

Policies provide the foundation for a comprehensive and effective security pro-

gram. The company is protected from surprises and gives the necessary authority

to the security activities of the organization. By communicating the company poli-

cies as directives, accountability and personal responsibility for adhering to the

security practices is established. The policies are utilized in determining or inter-

preting any conflicts that may arise. The policies also define the elements, scope,

and functions of the security management.

Types of Security Policies

Security policies may consist of different types, depending upon the specific need

for the policy (NIST, 2003). The different security policies work together to meet

4/9/23, 9:12 PM Chapter 6 Creating Effective Information Security Policies | Information Security Governance Simplified

https://learning.oreilly.com/library/view/information-security-governance/9781439811658/017-9781466551282-006.xhtml 12/30

the objectives of the comprehensive security program. Different policy types

include:

Organizational or program policy—This policy is issued by a senior manage-

ment individual who creates the authority and scope for the security program.

The purpose of the program is described and the assigned responsibility is de-

fined for carrying out the information security mission. The goals of confiden-

tiality, integrity, and availability would be addressed in the policy. Specific ar-

eas of security focus may be stressed, such as the protection of confidential in-

formation for a credit card company or heath insurance company, or the avail-

ability focus for a company maintaining mission-critical, high-availability sys-

tems. The policy should be clear as to the facilities, hardware, software, infor-

mation, and personnel that are in scope for the security program. In most

cases, the scope will be the entire organization, however, in larger organiza-

tions the security program may be limited in scope to a division or geographic

location. The organization policy sets out the high-level authority to define the

appropriate sanctions for failure to comply with the policy.

Functional, issue-specific policies—Although the organizational security policies

are broad in scope, the functional or issue-specific policies address areas of

particular security concern requiring clarification. The issue-specific policies

may be focused on the different domains of security and address areas such as

access control, contingency planning, segregation of duties principles, and so

forth. They may also address specific technical areas of existing and emerging

technologies, such as use of the Internet, e-mail and corporate communication

systems, wireless access, or remote system access. For example, an acceptable

use policy may define the responsibilities of the end user for using the corpo-

rate computer systems for business purposes only, or may allow the person

4/9/23, 9:12 PM Chapter 6 Creating Effective Information Security Policies | Information Security Governance Simplified

https://learning.oreilly.com/library/view/information-security-governance/9781439811658/017-9781466551282-006.xhtml 13/30

some incidental personal use provided the restrictions of ensuring usage is free

from viruses, spyware, downloading inappropriate pictures or software, or

sending chain letters through e-mail. These policies will depend upon the busi-

ness needs and the tolerance for risk. The policies contain the statement of the

issue, the statement of the organization’s position on the issue, the applicability

of the issue, compliance requirements, and sanctions for not following the

policy.

System specific policies—Areas where it is desired to have clearer direction or

greater control for a specific technical or operational area may have more de-

tailed policies. These policies may be targeted for a specific application or plat-

form. For example, a system-specific policy may address which departments

are permitted to input or modify information in the check writing application

for the disbursement of accounts payable payments.

The more detailed and issue specific the policy, the higher likelihood that the

policy will require more frequent changes. Typically, high-level organizational se-

curity policies will survive for several years, whereas those focused on the use of

technology will change much more frequently as technology matures and new

technology is added to the environment. Even if an organization is not currently

utilizing a technology, policies can explicitly strengthen the message that the tech-

nology is not to be used and is prohibited. For example, a policy regarding remov-

able media such as USB drives, or one regarding the use of wireless devices or

camera phones in the workplace, would reinforce the management intentions

around the acceptance or nonacceptance of these devices.

Standards

4/9/23, 9:12 PM Chapter 6 Creating Effective Information Security Policies | Information Security Governance Simplified

Whereas policies define what an organization needs, the standards take this a

step further and define the how. Standards provide the agreements that provide

interoperability within the organization through the use of common protocols.

Standards are the hardware and software security mechanisms selected as the

organization’s method of controlling security risks. Standards are prevalent in

many facets of our daily lives, such as the size of the tires on automobiles; specifi-

cations of the height, color, and format of the stop sign; and the wiring details of

the RJ11 plug on the end of the phone jack cable. Standards provide consistency in

the implementation as well as permit interoperability with reduced confusion.

There are many security standards that could be chosen to implement a particu-

lar solution. For example, when selecting a control for remote access identifica-

tion and authentication, an organization could decide to utilize login IDs and

passwords, strong authentication through a security token over dialup, or a vir-

tual private network (VPN) solution over the Internet.

Standards simplify the operation of the security controls within the company

and increase the efficiency. It is more costly to support multiple software pack-

ages, which do essentially the same activity. Imagine if each user was told to go to

the local computer store and purchase the antivirus product that they liked the

best. Some users would ask the sales person’s opinion, some would buy the least

expensive to meet their budget needs, and others might get the most expensive as-

suming this would provide the greatest protection. Without a consistent product

standard for antivirus products, the organization would be unsure as to the level

of protection provided. Additionally, each of these different products would have

different installation, update, and licensing considerations contributing to com-

4/9/23, 9:12 PM Chapter 6 Creating Effective Information Security Policies | Information Security Governance Simplified

https://learning.oreilly.com/library/view/information-security-governance/9781439811658/017-9781466551282-006.xhtml 15/30

plex management. It makes much sense to have consistent products chosen for

the organization versus leaving the product choice to every individual.

Determination of which standards meet the organization’s needs must be

driven by the security policies agreed by management. The standards provide the

specification of the technology to effectively enable the organization to become

successful in meeting the requirements of the policy. If in the example of the re-

mote access the organization was restricting information over the Internet or had

many users in rural areas with limited Internet access, then the VPN standard

over the Internet may not be a plausible solution. Conversely, for end users trans-

mitting large amounts of information, the dial-up solution may be impractical.

The policy defines the boundaries within which the standards must be

supportive.

Standards may also refer to those guidelines established by a standards organi-

zation and accepted by management. Standards creators include organizations

such as the National Institute of Standards and Technology (NIST), International

Organization for Standardization (ISO), Institute of Electrical and Electronics

Engineers (IEEE), American National Standards Institute (ANSI), and National

Security Agency (NSA).

Procedures

Procedures are step-by-step instructions in support of the policies, standards,

guidelines, and baselines. The procedure indicates how the policy will be imple-

mented and who does what to accomplish the tasks. The procedure provides clar-

ity and a common understanding to the operation required to effectively support

the policy on a consistent basis. Procedures are best developed when the input of

4/9/23, 9:12 PM Chapter 6 Creating Effective Information Security Policies | Information Security Governance Simplified

https://learning.oreilly.com/library/view/information-security-governance/9781439811658/017-9781466551282-006.xhtml 16/30

each of the interfacing areas are included in the development of the procedure.

This reduces the risk that important steps, communication, or required deliver-

ables are left out of the procedure.

Companies must be able to provide assurance that they have exercised due dili-

gence in the support and enforcement of company policies. This means that the

company has made an effort to be in compliance with the policies and has com-

municated the expectations to the workforce. Having documented procedures

communicated to the users, business partners, and anyone utilizing the systems

as appropriate, minimizes the legal liability of the corporation.

Creating documented procedures is more than a documentation exercise for

the sake of documentation. The process itself creates a common understanding

between the developers of the procedure of the methods used to accomplish the

task. Individuals from different organizational units may be very familiar with

their work area but not as familiar with the impact of a procedure on a depart-

ment. This is the “beach ball effect,” where organizations sometimes appear as a

large beach ball, and the individuals working in different departments can only

see their side of the beach ball and may not understand the other parts of the or-

ganization. The exercise of writing down a single, consistent procedure has the

added effect of establishing agreement between the parties. Many times at the be-

ginning of the process, individuals will think they all understand the process, only

to come to understand that people were really executing different, individual pro-

cesses to accomplish the task.

Consistent documentation of the procedures permits the ability to improve the

procedures. Once everyone understands the initial procedure, enhancements can

4/9/23, 9:12 PM Chapter 6 Creating Effective Information Security Policies | Information Security Governance Simplified

https://learning.oreilly.com/library/view/information-security-governance/9781439811658/017-9781466551282-006.xhtml 17/30

be applied and communicated to everyone. This provides a method to incorporate

the best thinking on the single procedure versus having multiple procedures for

the same operation with a mixture of good and bad practices.

Baselines

Baselines provide descriptions of how to implement security packages to ensure

that implementations are consistent throughout the organization. Different soft-

ware packages, hardware platforms and networks have different methods of en-

suring security. There are many different options and settings which must be de-

termined to provide the desired protection. An analysis of the available configura-

tion settings and subsequent settings desired form the basis for future, consistent

implementation of the standard. For example, turning off the telnet service may

be specified in the hardening baseline document for the network servers. A pro-

cedure for exceptions to the baseline would need to be followed in the event that

the baseline could not be followed for a particular device, along with the business

justification. The baselines are the specific rules necessary to implement the secu-

rity controls in support of the policy and standards, which have been developed.

Testing of the implemented security controls on a periodic basis assures that

the baselines are implemented according to the documented baselines. The base-

lines themselves should be reviewed periodically to ensure that they are suffi-

cient to address emerging threats and vulnerabilities. In large environments with

multiple individuals performing systems administration and responding to ur-

gent requests, there is an increased risk that one of the baseline configurations

may not be implemented properly. Internal testing identifies these vulnerabilities

and provides a mechanism to review why the control was or was not properly im-

4/9/23, 9:12 PM Chapter 6 Creating Effective Information Security Policies | Information Security Governance Simplified

https://learning.oreilly.com/library/view/information-security-governance/9781439811658/017-9781466551282-006.xhtml 18/30

plemented. Failures in training, adherence to baselines and associated proce-

dures, change control, documentation, or skills of the individual performing the

changes may be identified through the testing.

Guidelines

Guidelines are discretionary or optional controls used to enable individuals to

make judgments with respect to security actions. A good exercise is to replace the

word guideline with the word optional. If by doing so, the statements contained in

the “optional” category are what is desired to happen at the user’s discretion, then

it is an appropriate guideline. If on the other hand, the statements are considered

as required to adequately protect the security of the organization, then this

should be defined as part of a policy, standard, or baseline.

Guidelines are also those recommendations, best practices, and templates pro-

vided by other organizations such as the Control Objectives for Information and

Related Technology (COBIT), the Capability Maturity Model (CMM), ISO 17799,

British Standard 7799, security configuration recommendations such as those

from the NIST or NSA, organizational guidelines, or other governmental

guidelines.

Combination of Policies, Standards, Baselines, Procedures, and Guidelines

Policies, standards, baselines, procedures, and guidelines are closely related to

each other and may be developed as the result of new regulations, external indus-

try standards, new threats and vulnerabilities, emerging technologies, upgraded

hardware and software platforms, or risk assessment changes. Sometimes these

different areas are combined into single documents for ease of management of all

the documents. Keeping policies separate from the implementation components

(standards, baselines, and procedures) increases the flexibility and reduces the

cost of maintenance as the policies typically change less frequently than the sup-

porting processes to achieve compliance with the policy. The relationships be-

tween the policies, standards, baselines, procedures, and guidelines and the laws

and regulations providing the requirement to implement these governing activi-

ties is shown in Figure 6.1.

Figure 6.1 Relationships between policies, standards, procedures, baselines, and guidelines.

Policy Analogy   A useful analogy to remember the differences between policies,

standards, guidelines, and procedures is to think of a company that builds cabi-

nets, which has a hammer policy. The different components may be as follows:

Policy—”All boards must be nailed together using company-issued hammers to

ensure end product consistency and worker safety.” Notice the flexibility pro-

vided to permit the company to define the hammer type with changes in tech-

nology or safety issues. The purpose is also communicated to the employees.

Standard— “Eleven-inch fiberglass hammers will be used; only hardened-steel

nails will be used with the hammers; automatic hammers are to be used for

repetitive jobs >1 hour.” Technical specifics are provided to clarify the expecta-

tions that make sense for the current environment and represent

management’s decision.

Guideline—”To avoid splitting the wood, a pilot hole should be drilled first.” The

guideline is a suggestion and may not apply in all cases or all types of wood.

This does not represent a requirement, but rather a suggested practice.

Procedure—”(1) Position nail in upright position on board. (2) Strike nail with

full swing of hammer. (3) Repeat until nail is flush with board. (4) If thumb is

caught between nail and board, see Nail First-Aid Procedure.” The procedure

indicates the process of using the hammer and the nail to clarify what is ex-

pected to be successful. Following this procedure, with the appropriate stan-

dard hammers, and practicing guidelines where appropriate, will fulfill the

policy.

Analogies such as this can be effective when leading the team to develop secu-

rity policies to ensure that they are on the same wavelength and not mixing poli-

cies, procedures, standards, and guidelines. These can also be useful in security

awareness training to indicate when a particular user should refer to a policy,

standard, procedure, or guideline.

An Approach for Developing Information Security Policies

Let us assume for a moment that the guidance in the preceding sections were fol-

lowed, and the organization now has a set of information security policies that

are easy to read, kept current, and generally available in a nice format on the

Web. However, if no one seems to be reading them or following them, what could

be the problem? Many times the root cause is a lack of management support. How

could this be? After all, if the information security officer has been designated

with the role of developing and distributing information security policies, why

would there be a low acceptance rate? The answer usually lies in the fact that

while the information security officer may have done an excellent job research-

ing and developing security policies, the same diligence was not applied in ensur-

ing that the rest of management was on board with the policies prior to rollout.

The security officer may decide to push out the policies once his department has

developed them. As such, the policies become those “owned” by the security offi-

cer and not the rest of the management. These are then treated as departmental

policies that have no greater enforcement requirements than the policies and pro-

cedures that are created by their organizational area. Then, when there is a con-

flict between the departmental desires and the security policy, the departmental

desires win. For example, if an organization has to get information quickly to a

customer, it can fax or e-mail the information as part of its normal procedure.

However, the information security policy may require that all transmissions over

an open network, as in the case of e-mail, or that only the transmission of all con-

fidential information be encrypted with the most stringent government standard

encryption, such as Federal Information Processing Standard (FIPS) 140-2 encryp-

tion requirements. The department sending the information may have a disagree-

ment with the security department on the information classification of “confiden-

tial” in the information security policy, or may feel that the requirement is a bit

over the top and does not agree with the policy at all, as it would hamper the

speed of doing business and cause inferior relationships with customers. Who is

right? In this case, neither; the security officer failed to obtain agreement with the

policy before the procedures were executed and the executive from the other de-

partment is incorrect in not adhering to the policy. Unfortunately, this situation is

all too common. The good news is that this can be avoided by following a different

approach to developing and distributing the security policies.

Utilizing the Security Council for Policies

Management support is essential in the development of information security poli-

cies. So, how is that attained? One method that is very effective is to form a secu-

rity committee, also known as an information security council as introduced in

Chapter 4. The security council can review the policies proposed by the informa-

tion security department. The benefits of this approach are (1) consensus of the

policies are first built at the front-line supervisor/middle management/technical

staff level, (2) senior management has greater comfort that the policies will be ac-

cepted by the organization as the management team has reviewed them before

approval, and (3) it builds grassroots ownership of the information security poli-

cies. Although the information security council can also serve as oversight for

other security initiatives, serve as a sounding board, and prioritize information

security efforts, it can be especially effective in vetting and discussing the infor-

mation policies that are needed by the organization.

The Policy Review Process

Now that the organization has identified an individual responsible for the devel-

opment and implementation of security policies the security council has been cre-

ated, and an understanding of what makes a good policy has been communicated,

there needs to be a process for reviewing the policies. This process may be devel-

oped during the creation of the security council. What is important is that the pol-

icy development process is thought out ahead of time to determine who will (1)

create, (2) review and recommend, (3) approve the final version, (4) publish, and

(5) read and accept the policies. The time spent in this process, up front, will pro-

vide many dividends down the road. Many organizations jump right in and some-

one in the security department or information technology department to draft

then email the policy without taking these steps. Proceeding along that path ends

up with a policy that is not accepted by the organization’s management and thus

will not be accepted by the organization’s end users. Why? Because the necessary

discussion, debate, and acceptance of the policies by the leaders of the organiza-

tion never took place. In the end, the question of management commitment again

surfaces, when there was never a process in place to obtain the commitment.

The process could be depicted in a swim-lane-type chart showing the parties re-

sponsible, activities, records created through each activity, and decision boxes; or

a flowchart format. Senior management will want this presented at a high level,

typically no more than one to two pages of a process diagram. The process will

vary by organizational structure, geographic location, size, and culture of decision

making. However, a successful process for review should contain the following

steps, as depicted in Figure 6.2.

Figure 6.2 Security council policy development, approval, and distribution process.

1. Policy needs to be determined—Anyone can request the need for a policy to the

information security department. Business units may have new situations that

are not covered by an existing security policy. If no security policies exist in the

4/9/23, 9:12 PM Chapter 6 Creating Effective Information Security Policies | Information Security Governance Simplified

https://learning.oreilly.com/library/view/information-security-governance/9781439811658/017-9781466551282-006.xhtml 25/30

organization, the information security department needs to take the lead and

establish a prioritization of policies that are necessary.

2. Create, modify existing policy—The information security department creates an

initial draft for a new policy that can be reacted to. Caution must be taken not

to copy and distribute these policies taken from books or Internet sources as is

as they may not be completely appropriate, enforceable, or supported by proce-

dures within the organization.

3. Internal review by security department—People within the security department

will have varying levels of technical expertise, business acumen, and under-

standing of the organizational culture. By reviewing within the team first,

many obvious errors or misunderstandings of the policy can be avoided before

engaging management’s limited review time. This also increases the credibility

of the information systems security department by bringing a quality product

for review. It also saves time on minor grammatical reviews and focuses the

management review on substantive policy issues.

4. Security council reviews and recommends policy—This is arguably the most criti-

cal step in the process. This is where the policy begins the acceptance step

within the organization. The policies are read, line by line, during these meet-

ings and discussed to ensure that everyone understands the intent and ratio-

nale for the policy. Management’s commitment begins here. Why? Because the

management feels like part of the process and have a chance to provide input,

as well as thinking about how the policy would impact their individual depart-

ments. Contrast this method with just sending out the policy and saying “this is

it” and the difference becomes readily apparent. These are the same manage-

ment people that are being counted on to continue to support the policy once it

is distributed to the rest of the workforce. Failing in this step will guarantee

failure in having a real policy.

If we buy into the notion that a security council is a good practice, logical, prac-

tical, and appears to get the job done, what is the downside? Some may argue

that it is a slow process, especially when senior management may be pushing to

“get something out there to address security” to reduce the risks. It is a slow

process while the policies are being debated. However, the benefits of (1) hav-

ing a real policy that the organization can support, (2) buy-in from the manage-

ment on a continuing basis, (3) reduced need to rework the policies later, and

(4) increased understanding by management of the policies’ meanings and why

they are important outweigh the benefits of blasting out an e-mail containing

policies that were copied from another source, the name of the company

changed, and distributed without prior collaboration. Policies created in the

later context rarely become “real” and followed within the organization, as

they were not developed with thorough analysis of how they would be sup-

ported by the business in their creation.

5. Information technology steering committee approves policy—A committee made

up of the senior leadership of the organization is typically formed to oversee

the strategic investments in information technology. Many times these commit-

tees struggle with balancing decisions on tactical firefighting on short term is-

sues versus dealing with strategic issues, and this perspective needs to be un-

derstood when addressing this type of committee. The important element in the

membership of this committee is that it involves the decision leaders of the or-

ganization. These are the individuals that the employees will be watching to see

if they support the policies that were initially generated from the security de-

partment. Their review and endorsement of the policies is critical to obtain

4/9/23, 9:12 PM Chapter 6 Creating Effective Information Security Policies | Information Security Governance Simplified

https://learning.oreilly.com/library/view/information-security-governance/9781439811658/017-9781466551282-006.xhtml 27/30

support in implementing the policies. Also, they may be aware of strategic

plans or further operational issues not identified by middle management

(through the security council) that may make a policy untenable.

Since time availability of the senior leadership is typically limited, these com-

mittees meet at most on a monthly basis, but more typically on a quarterly ba-

sis. Therefore, sufficient time for planning policy approval is necessary. This

may seem to run counter to the speed at which electronic policies are distrib-

uted. However, as in the case with the security council review, the time delay is

essential in obtaining long-term commitment.

6. Publish policy—Organizations that go directly from step 2 to this step end up

with shelfware, or if e-mailed, “electronic dust.” By the time the policy gets to

this step, the security department should feel very confident that the policy will

be understood by the users and supported by management. Users may agree or

disagree with the policy, but will understand the need to follow it because it

will be clear how the policy was created and reviewed. Care must be taken

when publishing policies electronically, as it is not desirable to publish the

same policy over and over with minor changes to grammar and terminology.

Quality reviews need to be performed early in the development process so that

the security council and information technology steering committee can devote

their time to substantive issues of the policy versus pointing out the typos and

correcting spelling. End users should be given the same respect and should ex-

pect to be reviewing a document free from error. The medium may be elec-

tronic but that does not change the way people want to manage their work

lives. With the amount of e-mail already in our lives, we should try to limit the

amount of “extra work” that is placed upon the readers of the policies.

4/9/23, 9:12 PM Chapter 6 Creating Effective Information Security Policies | Information Security Governance Simplified

The Web-based policy management tools provide the facilities to publish the

policies very quickly. Since tracking of reading the policies is a key feature of

these products, once the policy is published, they typically cannot be changed

unless a new policy is created! This has major implications for the distribution

of the policy. This means that any change made will require the republishing of

the policy. Imagine thousands of users in the organization that now have to

reread the policy due to a minor change. This situation should be avoided with

the review process in place in the preceding steps. The electronic compliance

tracking software is usually built this way (and rightly so), so that it is clear

which policy version the user actually signed off on.

It should be clear by now that even though some of the policy development

tools support a workflow process within the tool to facilitate approvals of the poli-

cies through the various stages (such as draft, interim reviews, and final publish-

ing), there is no substitute for the oral collaboration on the policies. Electronic

communications are very flat and do not provide expression of the meaning be-

hind the words. Through the discussions within the various committees, the docu-

mented text becomes clearer beyond just those with technical skills. The purpose

is more apt to be appropriately represented in the final policies through the col-

laborative process.

Information Security Policy Process

Security policy development is a repetitive process, where existing policies are

updated and new ones are created as needed. The majority of the work is in creat-

ing the initial security policies, and hopefully, if these policies were written to the

appropriate level, modification of the policies should be minimal. The majority of

the work in policy development is evaluating the policies against the introduction

of new technologies, law and regulation changes, and changes to the business.

Most often, the existing polices will suffice and not require major change. This

rate of small change can cause organizations to not pay the appropriate attention

to the policy review and update.

As a final note, it should be clear through the activities presented in this chapter

that the information security officer is the facilitator of the information security

policy development, but should not own them. The security policies should be

owned by the organization, which in most cases, is represented by the CEO and

the executive management. There will be much less challenging of the security

policy if it is owned and issued at this level, than if it is owned by the security offi-

cer, who may reside at a lower level within the organization (except for large or-

ganizations where the CISO may be part of the executive team).

All other security procedures, standards, guidelines, and implementations are

dependent upon the construction of a consistent, easy-to-understand, coherent,

and comprehensive information security policy. The time investment in this step

is very valuable and the impact to the organization should not be underestimated.

Following the steps in this chapter will lead to more efficient and effective infor-

mation security policy development and subsequent acceptance.
