A Fault Attack is a technique to evaluate a system’s quality by intentionally triggering specific failures.
Key Aspects:
1. Deliberately introduce faults
2. Observe system response
3. Assess specific quality characteristics
4. Test system robustness and error handling
Common Fault Attack Methods:
1. Injecting invalid inputs
2. Modifying memory contents
3. Disrupting timing or synchronisation
4. Altering environmental conditions
Goals of Fault Attacks:
1. Identify vulnerabilities
2. Test error detection and recovery
3. Evaluate system stability
4. Assess security measures Fault attacks are often used in security testing and quality assurance processes to improve system resilience.
