Introduction
• The ubiquitous use of computers and technology prompts some very
important questions about the use of personal data and our right to
privacy.
• This chapter covers issues
related to the impact of
technology on people and
how to protect ourselves
on the Web.
People
Technology has had a very positive impact on people, but
some of the impact could be negative.
Most significant concerns:
• Privacy – What are the threats to personal privacy and how can we
protect ourselves?
• Security – How can access to sensitive information be controlled and
how can we secure hardware and software?
• Ethics – How do the actions of individual users and companies affect
society?
• Ergonomics - How do the science devoted to incorporating comfort,
efficiency, and safety into the design of items in the workplace?
Security
• Involves protecting individuals or organizations from theft
DEFINITION and danger
• Gain unauthorized access with malicious intent
HACKERS • Not all hackers are illegal
CYBERCRIME / • Criminal offense that involves a computer and a network
COMPUTER • Effects over 400 million people annually
• Costs over $400 billion each year
CRIME
Forms of Computer Crime
Malicious Programs - Malware
• Malicious Programs or Malware
• Designed by crackers, computer criminals, to
damage or disrupt a computer system
• Computer Fraud and Abuse Act makes spreading a
virus a federal offense
• 3 most common of malicious programs
VIRUSES WORMS TROJAN HORSE
• migrate through • fills the computer with • – programs disguised
networks and attach self-replicating as something else
to different programs information
• Zombies are computers infected by a virus, worm,
or Trojan Horse
Cyber Crime
Rogue Wi-Fi
Denial of Service Data manipulation
hotspots
• (DoS) attack • Imitate free Wi- • Finding entry
attempts to slow Fi networks and into someone’s
down or stop a capture any and computer
computer system all information network and
or network by sent by the users leaving a
flooding it with to legitimate prankster’s
requests for sites including message
information or usernames and
data passwords
Cyber Crime
Internet
Scams
Identity Theft Cyber-bullying Phishing
• A fraudulent or • Illegal assumption • Use of the Internet, • Attempts to trick
deceptive act or of someone’s cell phones, or Internet users into
operation to trick identity for purpose other devices to thinking a fake but
someone into of economic gain send or post official-looking
providing personal content intended to website is
information or harm legitimate
spending money for
little or no return
Types of Internet Scams
Measures to Protect Computer Security
Principle measures to ensure
computer security
• Restricting access
• Encrypting data
• Anticipating disasters
• Physical security
• Data security
• Disaster recovery plan
• Preventing data loss
Restricting Access
• Biometric scanning
• Fingerprint scanners
• Iris (eye) scanners
• Passwords
• Dictionary attack
• Uses software to try
thousands of common words
sequentially in an attempt to
gain unauthorized access to a
user’s account
Automated Security Tasks
Ways to perform and automate important security tasks
• Security Suites
• Provide a collection of utility programs designed to protect your privacy and
security
• Firewalls
• Security buffer between a corporation’s provide network and all external
networks
• Password Managers
• Helps to create strong passwords
Encryption
Coding information to make it unreadable, except to
those who have the encryption key
• E-mail encryption protects emails
• File encryption protects files
• Web site encryption uses HTTPS protocol for
protection
• HTTPS – hypertext transfer protocol secured
• Virtual private networks (VPNs)
• Encrypts connects between company networks and
their remote users
• Wireless network encryption restricts access to
authorized users
• WPA2 – Wi-Fi Protected Access
Anticipating Disasters
• Anticipating/Expecting Disasters
• Physical Security protects hardware
• Data Security protects software and data from unauthorized
tampering or damage
• Disaster Recovery Plan describes ways to continue operating in
the event of a disaster
• Preventing Data Loss
• Frequent backups
• Redundant data storage
• Store off-site in case of loss of equipment
Privacy
• Privacy – concerns the collection and use of data about
individuals
• Three (3) primary privacy issues:
• Accuracy – responsibility of those who collect data
• Must be secure and correct
• Property – who owns data and who has rights to software
• Access – responsibility of those who control data and use of
data
Large Databases
Large organizations compile information about us daily
• Big Data is exploding and ever-growing
• 90% of the data collected has been collected over the last 2
years
• Data collectors include
• Government agencies
• Telephone companies
• Credit card companies
• Supermarket scanners
• Financial institutions
• Search engines
• Social networking sites
• Information Resellers/Brokers

Large Databases (Cont.)
• Personal information is a marketable commodity, which raises
many issues:
• Collecting public, but personally identifying information (e.g., Google’s
Street View)
• Spreading information without personal consent, leading to identity
theft
• Spreading inaccurate information
• Mistaken identity
• Freedom of Information Act
• Entitlement to look at your records held by government agencies
Private Networks
Employee monitoring software
• Employers can monitor e-mail legally
• A proposed law could prohibit this type of
electronic monitoring or at least require the
employer to notify the employee first
The Internet and the Web
