Tamper Response Layer #2
Description
Description
Implement a modular tamper detection & response system. Detect physical or software-level tampering and trigger the configured response (e.g. wipe, alert, lockout).
Initial Ideas
- Self-checksumming of kernel module or memory region
- Physical tamper switches (e.g. GPIO pin triggers, chassis intrusion sensors)
- Detect unexpected code changes, binary hash mismatches, or unexpected syscall behavior
- Anti-debugging / integrity checks (optional, stealth layer)
Goals
- Modular detection hooks (plug into existing trigger system)
- Low overhead; avoid noisy or unreliable signals
- Configurable response action per tamper event
Future Extensions
- TPM integration for secure measurement
- UEFI secure boot attestation
- Integration with hardware watchdogs
- Logging mechanism for post-mortem analysis (if safe)
