Study Notes

CS1STF: Security Thinking & Fundamentals - Tutorial 1/10

  • Activities Outline:
    • Warm-up activity (15 minutes)
    • Individual worksheet (1 hour), including exam-style practice exercises
    • Review (20 minutes), model solutions available on Blackboard

Warm-up Activity

  • Focus: Revisiting threats

Vulnerability-Threat-Control Framework

  • A framework to understand protection methods
  • Describes how assets are harmed and how to mitigate harm
  • Shows the relationship between threats, vulnerabilities, the system, and controls

Threats in More Depth

  • Threat: A set of circumstances with the potential to cause harm, often by exploiting vulnerabilities
    • Causes:
      • Natural (e.g., fire, power failure)
      • Human (e.g., malicious intent, human error, benign intent)
    • Types:
      • Benign intent
      • Malicious intent
      • Random
      • Directed (e.g., impersonation)
      • Examples: 'malicious code on a general web site', 'human error'

Tutorial Worksheet

  • Step 1: Download worksheet from Blackboard
  • Step 2: Complete exercises individually or in groups; ask for tutor assistance if needed
  • Step 3 (optional): Post answers to discussion board on Blackboard (anonymously possible)
  • Step 4: Review and rate classmate's answers, provide feedback

Optional: Input to Discussions

  • Week 1/Exercise 2: Distinguish between threat, control, and vulnerability
  • Week 1/Exercise 4: Provide an example where a confidentiality breach leads to a compromise in integrity
  • Week 1/Exercise 6: Identify relevant assets, and associated threats.
