Information Governance and Information Privacy

& Security Functions ITS 833

Dr. Mia Simmons

Chapter Overview

■ This chapter will cover pages 207-236 in

your book.

■ This chapter discusses how privacy &

security aligns directly with the success of

Information Governance.

2

Privacy

■ Privacy cannot be protected without implementing proper

security controls and technologies

3

Insider Threat: Malicious or Not

■ Countering the Insider Threat

– Insider threat breaches can be more costly than outsider breaches

■ Malicious Insider

– Malicious insiders have many methods at their disposal to harm the organization by destroying equipment, gaining unsanctioned access to IP, or removing sensitive information by USB drive, e- mail, or other methods.

■ Nonmalicious Insider

– The majority of users indicated having sent out documents accidentally email

■ Solution

– companies need to take a hard look and see whether they have any effective IG enforcement and document life cycle security (DLS) technology such as information rights management (IRM) in place

Privacy Laws ■ Federal Wiretap Act “prohibits the unauthorized interception and

disclosure of wire, oral, or electronic communications.”

■ United Kingdom, privacy laws and regulations include these:

– Data Protection Act 1998

– Freedom of Information Act 2000

– Public Records Act 1958

– Common law duty of confidentiality

– Confidentiality National Health Service (NHS) Code of Practice

– NHS Care Record Guarantee for England

– Social Care Record Guarantee for England

– Information Security NHS Code of Practice

– Records Management NHS Code of Practice

■ Redaction is the process of blocking out sensitive fi elds of information.

Limitations of Perimeter Security

■ The perimeter security approach has four fundamental limitations:

1. Limited effectiveness. Perimeter protection stops dead at the firewall, even though sensitive information is sent past it and circulates around the Web, unsecured. Today’s extended computing model and the trend toward global business means that business enterprises and government agencies frequently share sensitive information externally with other stakeholders, including business partners, customers, suppliers, and constituents.

2. Haphazard protections. In the normal course of business, knowledge workers send, work on, and store copies of the same information outside the organization’s established perimeter. Even if the information’s new digital environment is secured by other perimeters, each one utilizes different access controls or sometimes no access control at all (e.g., copying a price list from a sales folder to a marketing folder; an attorney copying a case brief or litigation strategy document from a paralegal’s case folder).

3. Too complex. With this multi-perimeter scenario, there are simply too many perimeters to manage, and often they are out of the organization’s direct control.

4. No direct protections. Attempts to create boundaries or portals protected by perimeter security within which stakeholders (partners, suppliers, shareholders, or customers) can share information causes more complexity and administrative overhead while it fails to protect the e-documents and data directly

6

Controlling Access Using Identity Access Management

■ IAM—along with sharp IG policies—“manages and governs user access to information through an automated, continuous process

■ A robust and effective IAM solution provides for:

– Auditing . Detailed audit trails of g who attempted to access which information , and when . Stolen identities can be uncovered if, for instance, an authorized user attempts to log in from more than one computer at a time.

– Constant updating. Regular reviews of access rights assigned to individuals, including review and certification for user access, an automated recertification process ( attestation ), and enforcement of IG access policies that govern the way users access information in respect to segregation of duties.

– Evolving roles. Role life cycle management should be maintained on a continuous basis, to mine and manage roles and their associated access rights and policies.

– Risk reduction. Remediation regarding access to critical documents and information

7

Enforcing IG: Protect Files with Rules and Permissions

■ Rules and permissions specify who (by roles) is allowed

access to which documents and information, and even

contextually from where (office, home, travel) and at what

times (work hours, or extended hours).

■ To effectively wall off and secure information by management

level, many companies and governments have put in place an

information security framework—a model that delineates

which levels of the organization have access to specifi c

documents and databases as a part of implemented IG policy

8

Apply Better Technology for Better Enforcement in the Extended Enterprise

■ Protecting E-Documents in the Extended Enterprise

– Sharing e-documents and collaborating are essential in today’s

increasingly mobile and global world

■ Basic Security for the Microsoft Windows Office Desktop

– A key flaw or caveat is that passwords used in protecting documents

cannot be retrieved if they are forgotten or lost.

■ Where Do Deleted Files Go?

– Most users are unaware that deleted fi les and fragments of

documents and drafts are stored temporarily on their computer’s

unallocated space.

■ Lock Down: Stop All External Access to Confidential E-Documents

– these methods are effective in highly classified or restricted areas

where confidential e-documents are held.

9

Apply Better Technology for Better Enforcement in the Extended Enterprise

■ Secure Printing

– You simply invoke some standard Microsoft Office protections,

which allow you to print the documents once you arrive in the copy

room or at the networked printer.

■ Serious Security Issues with Large Print Files of Confidential Data

– To help secure print fi les, specialized hardware devices designed to

sit between the print server and the network and cloak server print

files are visible only to those who have a cloaking device on the other

end

10

Secure Communications Using Record-Free E-Mail

■ Stream messaging is a simple, safe, secure electronic communications

system ideal for ensuring that sensitive internal information is kept

confidential and not publicly released

■ Stream messaging separates the sender’s and receiver’s names and

the date from the body of the message, never allowing them to be seen

together. Even if the sender or receiver were to attempt to make a copy

using the print-screen function, these elements are never captured

together

■ Stream messaging is unique because its technology effectively

eliminates the ability to print, cut, paste, forward, or save a message.

11

Digital Signatures

■ A digital signature provides evidence in demonstrating to a third party

that the signature was genuine, true, and authentic, which is known as

nonrepudiation

■ Digital signatures can be implemented a variety of ways—not just

through software but also through firmware (programmed microchips),

computer hardware, or a combination of the three.

■ A formal, trusted certificate authority (CA) issues the certificate

associated with the public-private key.

12

Document Encryption

■ There are e-records management implications of employing document

encryption:

– Unless it is absolutely essential, full document encryption is often

advised against for use within electronic records management

systems as it prevents full-text indexing, and requires that the

decryption keys (and application) are available for any future

access. Furthermore, if the decryption key is lost or

13

Data Loss Prevention (DLP) Technology

■ The aforementioned document security challenges have given rise to an

emerging but critical set of capabilities by a new breed of IT companies

that provide data loss prevention (DLP) (also called data leak

prevention).

■ Basic DLP Methods DLP solutions typically apply one of three methods:

1. Scanning traffic for keywords or regular expressions, such as

customer credit card or Social Security numbers.

2. Classifying documents and content based on a predefined set to

determine what is likely to be confidential and what is not.

3. Tainting (in the case of agent-based solutions), whereby documents

are tagged and then monitored to determine how to classify

derivative documents. For example, if someone copies a portion of

a sensitive document into a different document, this document

receives the same security clearance as the original document.

14

Missing Piece: Information Rights Management (IRM

■ “IRM” when referring to this technology set, so as not to be confused with electronic records management. Major software companies also use the term “IRM.”

■ The ability to apply security to an e-document in any state (in use, in motion, and at rest), across media types, inside or outside of the organization, is called persistent security.

■ Three requirements are recommended to ensure effective IRM:

1. Security is foremost; documents, communications, and licenses should be encrypted, and documents should require authorization before being altered.

2. The system can’t be any harder to use than working with unprotected documents.

3. It must be easy to deploy and manage , scale to enterprise proportions, and work with a variety of common desktop applications

15

Policy Creation and Management ■ IG policy defined for a document type includes these following controls:

1. Viewing

2. Editing

3. Copy/Paste (including screen capture)

4. Printing

5. Forwarding e-mail containing secured e-documents

■ Decentralized Administration

– One of the key challenges of e-document security traditionally is that a system administrator had access to documents and reports

■ Integration

– The best approach is to target one critical department or area with a strong business need and to keep the scope of the project narrow to gain an early success before expanding the implementation into other departments.

– IRM embeds protection into the data (using encryption technology), allowing fi les to protect themselves.

16

Embedded Protection

■ Locking down data involved encryption in one form or another:

1. E-mail encryption

2. File encryption

3. Full Disk Encryption (FDE)

4. Enterprise wide encryption

■ These encryption solutions can be divided into two categories:

1. encryption in transit (e.g., e-mail encryption)

2. encryption t at rest (e.g., FDE)

17

Approaches for Securing Data Once It Leaves the Organization

■ Forrester has developed a new network architecture that builds security into the DNA of a network, using a mixture of five data security design patterns:

1. Thin client. Access information online only, with no local operations, using a diskless terminal that cannot store data, documents, or programs so confidential information stays stored and secured centrally.

2. Thin device. Devices such as smartphones, which have limited computing resources, Web surfing, e-mail, and basic Web apps that locally conduct no real information processing, are categorized as thin devices.

3. Protected process. This approach allows local processing with a PC where confidential e-documents and data are stored and processed in a partition that is highly secure and controlled.

4. Protected data. Deploying IRM and embedding security into the documents (or data) provides complete DLS

5. Eye in the sky.

18

Document Labeling ■ Document Labeling

– Document labeling is “an easy way to g increase user

awareness about the sensitivity of information in a

document

– The challenge is to standardize and formalize the

process of getting the label onto the document—

enterprisewide

■ Document Analytics

– Document analytics allows a compliance officer or

system administrator to view exactly how many

documents a user accesses in a day and how many

documents the user accesses on average

19

Confidential Stream Messaging ■ The ePolicy Institute offers seven steps to controlling stream messaging:

1. Work with your legal counsel to define “business record” for your

organization on a companywide basis.

2. Work with your legal counsel to determine when, how, why, and with

whom confidential stream messaging is the most appropriate,

effective— and legally compliant—way to hold recordless, confidential

business discussions when permanent records are not required.

3. In order to preserve attorney-client privilege, a phone call or

confidential electronic messaging may be preferable to email.

4. Define key terms for employees.

5. Implement written rules and policies governing the use of email and

confidential stream messaging.

6. Distribute a hard copy of the new confidential messaging policy, email

policy and other electronic communications (e.g., social media, blogs)..

7. Educate, educate, educate. Ensure that all employees who need to

know the difference between email which leaves a potential business

record and stream messaging which does not, and is confidential

20

Chapter Summary ■ Data governance software is another tool that looks at who is accessing which documents

and creates a matrix of roles and access along behavioral lines.

■ Encrypting sensitive e-mail messages is an effective step to securing confidential information assets while in transit. Encryption can be applied to desktop folders and fi les.

■ For e-mail communication with no trace or record, stream messaging is a solution.

■ Digital signatures authenticate the identity of the signatory and prove that the signature was, in fact, generated by the claimed signatory. This is known as nonrepudiation.

■ Data loss prevention technology performs a “deep content inspection” of all e-documents and e-mails before they leave the organization’s perimeter to stop sensitive data from exiting the firewall.

■ DLP can be used to discover the flow of information within an organization. Additional security tools can then be applied. This may be the best use for DLP.

■ Information rights management software enforces and manages use rights of electronic documents. IRM provides a sort of security wrapper around documents and protects sensitive information assets from unauthorized use or copying. IRM is also known as enterprise rights management.

■ Persistent security tools like IRM should be enforced on price lists, proprietary blueprints, and CAD designs. Printing these documents should be highly restricted.

■ Most legacy or first-to-market providers of IRM focused on internal sharing and are heavily dependent on Microsoft Active Directory and lightweight directory access protocol (LDAP) for authentication. These early solutions were not built for cloud use or the distributed enterprises of today, where mobile devices are proliferating.
