Study Notes
Computer Crime and Information Systems Security
-
Types of Computer Criminals:
- Hackers/Crackers: Originally, hackers were motivated by curiosity, but the term "cracker" emerged for those intentionally breaking in. "White hat" hackers are motivated by curiosity, while "black hat" crackers aim to cause harm.
- Hacktivists: Crackers motivated by political or ideological goals, often defacing websites or disrupting systems.
- Insider Threats: Current or former employees who misuse access for theft or damage; frequently the most common cause of crime.
- People with technical knowledge: Individuals using tech skills to commit business or information sabotage.
- Career criminals: Utilizing computers to aid existing criminal activities.
-
Outsiders: Hackers/crackers who penetrate systems for malicious intent or information gathering.
- This includes those attempting to gain access without authorization to store records of illegal transactions, or for electronic money laundering.
-
Priorities by frequency of violations:
- Current/former employees (most common)
- Individuals with technical knowledge
- Career criminals
- Outsiders/crackers (committing millions of intrusions but often causing little harm)
-
Methods of Computer Criminal Intrusion:
- Vulnerability scanners: Automated tools for identifying system weaknesses.
- Packet sniffers: Analyze network traffic, capturing unencrypted passwords.
- Keyloggers: Record every keystroke, gathering sensitive data.
- Brute-force attacks: Tools attempting to guess passwords.
-
Industrial Espionage:
- Covert activities (theft of trade secrets, bribery, blackmail, technological surveillance) to gain a competitive edge.
- Increasingly involves cracking into company computer systems to steal confidential data and trade secrets.
-
Information Systems Security:
- Safeguarding all aspects of information systems (hardware, software, networks, data) from unauthorized access, destruction, or manipulation, while allowing authorized users access.
- Key aspects:
- Availability: Legitimate user access to the system.
- Integrity: Preventing unauthorized data manipulation.
- Confidentiality: Protecting data from unauthorized access.
- Accountability: Tracing actions within the system.
-
Information Systems Security Process:
- Risk assessment: Understanding risks to availability, integrity, and confidentiality. Assess asset value, probability of compromise, and associated costs (protection costs vs asset value and probability). Consider technical (databases, hardware) and non-technical information (processes, physical/personnel security). A "risk rating" guides security strategy.
-
Security strategy development: Implementing policies and controls based on risk assessment, addressing information systems controls (technology, people, policies).
-
Risk Management Strategies:
- Risk reduction: Lessening potential negative impacts.
- Risk acceptance: Acknowledging and accepting some risks.
- Risk transference: Transferring risk (e.g., insurance).
- Risk avoidance: Avoiding risk entirely (often impractical).
-
Risk Management Strategies:
-
Vulnerabilities & Threats:
- Exploitable weaknesses in systems or security policies ("known" or "expected").
- Undesirable events causing harm (internal or external agents).
