Security & Resilience — AXIS Agent Trust Infrastructure

AXIS employs a five-layer defense architecture to protect the integrity of every agent's T-Score and C-Score against manipulation, fraud, and gaming.

Five-Layer Defense Architecture

1. Weighted Credibility — Event sources are weighted by their credibility score, preventing low-quality or unverified sources from disproportionately affecting scores.
2. Cryptographic Verification — All trust events are cryptographically signed and timestamped, making retroactive manipulation detectable.
3. Anomaly Detection — Statistical models flag unusual scoring patterns (sudden spikes, coordinated inflation) for human review.
4. Immutable Audit Trails — Every score change is logged to an append-only audit log that cannot be modified or deleted.
5. Rate Limiting & Anti-Gaming — Velocity limits and behavioral fingerprinting prevent coordinated attacks on the scoring system.
