From 45eced0b3e45d17d479dd5eac315bdfb20f747ca Mon Sep 17 00:00:00 2001 From: diegosouzapw Date: Mon, 16 Feb 2026 14:29:50 -0300 Subject: [PATCH] docs: comprehensive SECURITY.md based on full codebase audit Documented all security features actually implemented: - AES-256-GCM encryption at rest (API keys, tokens) - Prompt injection guard (5 pattern types) - PII redaction (email, CPF, CNPJ, CC, phone, SSN) - Secrets validator (fail-fast on weak values) - Circuit breaker (3-state, SQLite-persisted) - OAuth 2.0 + PKCE, CORS, IP filtering - Rate limiting, anti-thundering herd - Compliance (log retention, audit log, no-log) --- SECURITY.md | 129 ++++++++++++++++++++++++++++++++++++++++++++++------ 1 file changed, 116 insertions(+), 13 deletions(-) diff --git a/SECURITY.md b/SECURITY.md index 61effc8237..b917458b90 100644 --- a/SECURITY.md +++ b/SECURITY.md @@ -24,43 +24,146 @@ If you discover a security vulnerability in OmniRoute, please report it responsi | 0.6.x | ✅ Security | | < 0.6.0 | ❌ Unsupported | -## Security Best Practices +--- -### Required Environment Variables +## Security Architecture -All secrets must be set before starting the server.
