Security Hardening & SELinux
Compliance as an engineering discipline — baselines automated and evidence produced as a byproduct of operations.
Federal environments audit security, they don't assume it.
AASHU implements the hard controls most teams route around: SELinux stays enforcing, STIG findings close as automation rather than tickets, and every control maps to evidence an assessor can accept.
What this capability covers.
Focused engineering with clear technical outcomes, documented implementation, and a path for the operating team to own the result.
SELinux engineering
Enforcing mode as the standard: policy analysis, custom modules, boolean and context management.
SELinux troubleshooting
AVC denial analysis so applications run and security stays on — root cause documented, not masked.
STIG / CIS hardening
DISA STIG and CIS implementation across the fleet — automated, exception-tracked, drift-checked.
OpenSCAP scanning
Scheduled scans with remediation pipelines and trend reporting, per system and per profile.
FIPS & crypto policy
FIPS-mode enablement and system-wide cryptographic policies implemented and verified.
Firewall & audit
firewalld zones, auditd rulesets mapped to requirements, and SIEM-ready log forwarding.
What you receive.
From environment understanding to operational ownership.
Every engagement is scoped to the actual environment. The implementation changes by capability, but the operating discipline remains consistent.
Assess the environment
Map the current state, dependencies, constraints, risk, and operational ownership before making changes.
Engineer the implementation
Build the technical path with repeatable configuration, validation, and rollback appropriate to the scope.
Leave an operating model
Document the baseline, runbooks, lifecycle tasks, and handoff so the capability remains supportable.
