‹#›
8
INFORMATION ETHICS
Acting ethically and legally are not always the same
‹#›
9

‹#›
10
DEVELOPING INFORMATION MANAGEMENT POLICIES
Organizations strive to build a corporate culture based on ethical principles that employees can understand and implement
‹#›
11

The ethical computer user policy ensures all users are informed of the rules and, by agreeing to use the system on that basis, consent to abide by the rules
‹#›
12
Information Privacy Policy
The unethical use of information typically occurs “unintentionally” when it is used for new purposes
Information privacy policy - Contains general principles regarding information privacy
‹#›
13
Acceptable Use Policy
Acceptable use policy (AUP) – Requires a user to agree to follow it to be provided access to corporate email, information systems, and the Internet
Nonrepudiation – A contractual stipulation to ensure that ebusiness participants do not deny their online actions
Internet use policy – Contains general principles to guide the proper use of the Internet
‹#›
14
Email Privacy Policy
Organizations can mitigate the risks of email and instant messaging communication tools by implementing and adhering to an email privacy policy
Email privacy policy – Details the extent to which email messages may be read by others
‹#›
15
Email Privacy Policy
‹#›
16
Email Privacy Policy
Spam – Unsolicited email
Anti-spam policy – Simply states that email users will not send unsolicited emails (or spam)
‹#›
17
Social Media Policy

‹#›
18
WORKPLACE MONITORING POLICY
Workplace monitoring is a concern for many employees
Organizations can be held financially responsible for their employees’ actions
The dilemma surrounding employee monitoring in the workplace is that an organization is placing itself at risk if it fails to monitor its employees, however, some people feel that monitoring employees is unethical
‹#›
19
WORKPLACE MONITORING POLICY
Information technology monitoring – Tracks people’s activities by such measures as number of keystrokes, error rate, and number of transactions processed
Employee monitoring policy – Explicitly state how, when, and where the company monitors its employees
‹#›
20
WORKPLACE MONITORING POLICY
Common monitoring technologies include:
Key logger or key trapper software
Hardware key logger
Cookie
Adware
Spyware
Web log

LEARNING OUTCOMES
Describe the relationships and differences between hackers and viruses
Describe the relationship between information security policies and an information security plan
Provide an example of each of the three primary security areas: (1) authentication and authorization, (2) prevention and resistance, and (3) detection and response
‹#›
23
PROTECTING INTELLECTUAL ASSETS
Organizational information is intellectual capital - it must be protected
Information security – The protection of information from accidental or intentional misuse by persons inside or outside an organization
Downtime – Refers to a period of time when a system is unavailable
‹#›
24
PROTECTING INTELLECTUAL ASSETS
Sources of Unplanned Downtime

25
PROTECTING INTELLECTUAL ASSETS
How Much Will Downtime Cost Your Business?
‹#›
26
Security Threats Caused by Hackers and Viruses
Hacker – Experts in technology who use their knowledge to break into computers and computer networks, either for profit or just motivated by the challenge
Black-hat hacker
Cracker
Cyberterrorist
Hactivist
Script kiddies or script bunnies
White-hat hacker
‹#›
27
Security Threats Caused by Hackers and Viruses
Virus - Software written with malicious intent to cause annoyance or damage
Backdoor program
Denial-of-service attack (DoS)
Distributed denial-of-service attack (DDoS)
Polymorphic virus
Trojan-horse virus
Worm
‹#›
28
Security Threats Caused by Hackers and Viruses
How Computer Viruses Spread
‹#›
29
Security Threats Caused by Hackers and Viruses
Security threats to ebusiness include
Elevation of privilege
Hoaxes
Malicious code
Packet tampering
Sniffer
Spoofing
Splogs
Spyware
‹#›
30
THE FIRST LINE OF DEFENSE - PEOPLE
Organizations must enable employees, customers, and partners to access information electronically
The biggest issue surrounding information security is not a technical issue, but a people issue
Insiders
Social engineering
Dumpster diving
Pretexting
‹#›
31
THE FIRST LINE OF DEFENSE - PEOPLE
The first line of defense an organization should follow to help combat insider issues is to develop information security policies and an information security plan
Information security policies
Information security plan
‹#›
32
THE SECOND LINE OF DEFENSE - TECHNOLOGY
There are three primary information technology security areas
‹#›
33
Authentication and Authorization
Identity theft – The forging of someone’s identity for the purpose of fraud
Phishing – A technique to gain personal information for the purpose of identity theft, usually by means of fraudulent email
Pharming – Reroutes requests for legitimate websites to false websites
‹#›
34
Authentication and Authorization
Authentication – A method for confirming users’ identities
Authorization – The process of giving someone permission to do or have something
The most secure type of authentication involves
Something the user knows
Something the user has
Something that is part of the user
‹#›
35
Something the User Knows Such As a User ID and Password
This is the most common way to identify individual users and typically contains a user ID and a password
This is also the most ineffective form of authentication
Over 50 percent of help-desk calls are password related
‹#›
36
Smart cards and tokens are more effective than a user ID and a password
Tokens – Small electronic devices that change user passwords automatically
Smart card – A device that is around the same size as a credit card, containing embedded technologies that can store information and small amounts of software to perform some limited processing
Something the User Knows Such As a User ID and Password
‹#›
37
Something That Is Part Of The User Such As a Fingerprint or Voice Signature
This is by far the best and most effective way to manage authentication
Biometrics – The identification of a user based on a physical characteristic, such as a fingerprint, iris, face, voice, or handwriting
Unfortunately, this method can be costly and intrusive
‹#›
38
Prevention and Resistance
Downtime can cost an organization anywhere from $100 to $1 million per hour
Technologies available to help prevent and build resistance to attacks include
Content filtering
Encryption
Firewalls
‹#›
39
Prevention and Resistance
Content filtering - Prevents emails containing sensitive information from transmitting and stops spam and viruses from spreading
‹#›
40
Prevention and Resistance
If there is an information security breach and the information was encrypted, the person stealing the information would be unable to read it
Encryption
Public key encryption (PKE)
Certificate authority
Digital certificate
‹#›
41
Prevention and Resistance
‹#›
42
Prevention and Resistance
One of the most common defenses for preventing a security breach is a firewall
Firewall – Hardware and/or software that guards a private network by analyzing the information leaving and entering the network
‹#›
43
Prevention and Resistance
Sample firewall architecture connecting systems located in Chicago, New York, and Boston
‹#›
44
Detection and Response
If prevention and resistance strategies fail and there is a security breach, an organization can use detection and response technologies to mitigate the damage
Intrusion detection software – Features full-time monitoring tools that search for patterns in network traffic to identify intruders
