| Thank you so much. Now let me break this questions down: Key Security Benefits: 1. Cryptographic Verification: - Prevents silent corruption of system state - Makes tampering with system logs cryptographically difficult - Provides verifiable audit trails of all system operations - Enables detection of hardware memory faults 2. Runtime Integrity: - Prevents invalid memory access patterns - Ensures filesystem operations maintain consistency - Verifies process state transitions - Guards against buffer overflows in key subsystems Main Tradeoffs: 1. Performance Impact:
- 3-5% overhead for memory operations - 7-9% overhead for filesystem operations - Additional storage needed for proof chains - Increased memory usage for verification structures 2. Complexity:
- More complex memory management - Additional failure modes to handle - Higher system initialization overhead - More complex recovery procedures Attack Vectors Still Present: - Physical hardware attacks (DMA, cold boot) - Side-channel attacks - Race conditions (though reduced by verification) - Attacks that operate within valid operation boundaries - Core CPU/firmware-level vulnerabilities Attack Vectors Prevented/Mitigated: - Memory corruption exploits - Filesystem integrity attacks - Unauthorized state transitions - Historical state tampering - Many types of privilege escalation Im actively working on making the other attack vectors disappear as a whole. It's quite extensive as it is, so it's got a lot of things packed on it. ( * ´ ω ｀ * ) |
