syn-security — Security orchestration crate

Classification: PUBLIC
Crate: fruit/crates/syn-security/
Milestone: v4+
License: Apache-2.0
Version: v111.0.0 “Last Light”

What It Is

syn-security is the security orchestration framework for Syn_OS, implementing authentication, cryptography, audit logging, input validation, and zero-trust networking primitives. It bridges the AI engine (syn-ai) into security policy decisions via a consciousness_bridge module, and provides both standard and quantum-resistant security enhancements through modular feature flags.

Architecture

Master-only

All syn-security kernel operations require CAP_SYS_ADMIN. Device nodes are 0600 via udev rules. Do not expose to untrusted userspaces.

Modules

Module	Purpose
audit	Audit logging subsystem for compliance and forensic trails
auth	Authentication framework with session management and policy enforcement
consciousness_bridge	Bridge between syn-ai neural states and security trust decisions
crypto	Cryptographic primitives for hashing, key derivation, and secure comparison
ebpf_integration	eBPF-based kernel-level monitoring via libbpf-rs (optional)
encryption	Symmetric and asymmetric encryption with ChaCha20-Poly1305 and AES-GCM
enhanced_monitoring_minimal	Minimal-footprint behavioral monitoring for constrained environments
quantum_auth	Quantum-resistant authentication primitives
validation	Input validation and sanitization framework
zero_trust	Zero-trust networking policies and service-mesh enforcement
security_enhancements	Behavioral analytics, anomaly detection, and adaptive trust levels

How It’s Wired

1. syn-ai consciousness bridge — The consciousness_bridge module consumes AIState from syn-ai and translates neural activation levels and pattern counts into TrustLevel and anomaly scores, directly influencing zero-trust policy enforcement.
2. eBPF live integration — The ebpf-integration feature flag enables libbpf-rs-based kernel monitoring; ebpf-live (off-by-default) activates real ring-buffer readers once the data pipeline is fully wired.
3. Quantum security — quantum-security feature flag enables PQC auth paths that delegate to synos-icarus primitives in future milestones.
4. Compliance crates — mssp-platform and blue-team-defense feature bundles compose audit-logging, threat-detection, quantum-security, and ebpf-integration for MSSP operator profiles.

Future Ideas

Long-term enhancements (v112+)

1. Replace the hand-rolled security_enhancements behavioral analytics with a dedicated syn-security-behavior crate backed by synos-threat-hunting timeline analysis.
2. Add libbpf-rs CO-RE (Compile Once — Run Everywhere) support so eBPF programs work across kernel versions without recompilation.
3. Expose syn-security event types via synos-findings-store so all security decisions are content-addressed and deduplicated across the hive.
