Fault Injection

A security testing technique where faults are intentionally introduced to analyze system behavior.

Understanding Fault Injection


Fault injection is primarily used in penetration testing, hardware security assessments, and software robustness analysis. By simulating faults, security researchers and engineers can identify weaknesses before real-world attacks exploit them.

Types of Fault Injection


  1. Software Fault Injection – Modifies code, memory, or network packets to introduce errors in applications.

  2. Hardware Fault Injection – Uses voltage glitches, electromagnetic interference, or laser fault injections to manipulate hardware components.

  3. Network Fault Injection – Introduces network latency, packet loss, or corrupt data to analyze network resilience.

Challenges and Considerations


  • Risk of System Damage – Hardware fault injection can physically harm devices if not carefully executed.

  • Complex Setup – Requires specialized tools and expertise for proper execution.

  • Legal and Ethical Concerns – Unauthorized fault injection can be considered illegal hacking.
