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).
  • Vulnerabilities & Threats:

    • Exploitable weaknesses in systems or security policies ("known" or "expected").
    • Undesirable events causing harm (internal or external agents).
