Security Architecture
Secure by Design, Defense in Depth
LIBUX implements overlapping security controls at every layer — hardware, kernel, OS, application, and identity — to minimize attack surface and maximize resilience.
Kernel Hardening
- KASLR — Kernel Address Space Layout Randomization
- Stack Canaries & CFI (Control Flow Integrity)
- SMAP/SMEP (CPU protection)
- Kernel Lockdown Mode
- Module signing enforcement
- BPF JIT hardening
Access Control
- SELinux type enforcement (Mandatory Access Control)
- AppArmor profile confinement
- Landlock filesystem restrictions
- seccomp-bpf syscall filtering
- Capability dropping
- Privilege separation
Detection & Response
- Falco eBPF runtime threat detection
- Auditd kernel audit subsystem
- OSSEC / Wazuh HIDS
- ClamAV / open-source AV
- EDR integration (Elastic, Velociraptor)
- Memory forensics (Volatility)
Supply Chain
- Sigstore transparent signing
- Cosign image/artifact signing
- SBOM (CycloneDX / SPDX)
- SLSA Level 3 provenance
- Reproducible builds
- Dependency vulnerability scanning
Memory Protection
- Full ASLR enforcement
- NX/XD (No-eXecute) bit
- Heap protection (glibc hardening)
- SafeStack / ShadowCallStack
- RELRO (Relocation Read-Only)
- Fortify source hardening
Monitoring & SIEM
- OpenTelemetry unified telemetry
- Prometheus + Grafana
- OpenSearch Security Analytics
- SOAR automation (TheHive/Cortex)
- Threat intelligence feeds
- Executive security dashboards
