Security Hardening & SELinux

Compliance as an engineering discipline — baselines automated and evidence produced as a byproduct of operations.

Overview

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.

Service offerings

What this line covers.

Focused engineering with clear outcomes, documented implementation, and a path for your team to own the result.

01

SELinux engineering

Enforcing mode as the standard: policy analysis, custom modules, boolean and context management.

02

SELinux troubleshooting

AVC denial analysis so applications run and security stays on — root cause documented, not masked.

03

STIG / CIS hardening

DISA STIG and CIS implementation across the fleet — automated, exception-tracked, drift-checked.

04

OpenSCAP scanning

Scheduled scans with remediation pipelines and trend reporting, per system and per profile.

05

FIPS & crypto policy

FIPS-mode enablement and system-wide cryptographic policies implemented and verified.

06

Firewall & audit

firewalld zones, auditd rulesets mapped to requirements, and SIEM-ready log forwarding.

Deliverables

What you receive.

Hardening automation covering the selected baseline
SELinux policy modules with documented rationale
Continuous scan pipeline with remediation reports
Exception register with risk-acceptance documentation
Audit-ready evidence package per cycle
Security runbooks and analyst handoff
Engagement models

Three ways to bring the capability in.

Fixed-scope project, monthly retainer, or staffed capacity embedded with your program.

FIXED-SCOPE PROJECT

Defined outcome, defined price

Scope, deliverables, and exit criteria agreed before work starts.

RETAINER

Reserved monthly capacity

Ongoing operations and expertise without a new contract per task.

STAFFED CAPACITY

Engineering on-program

Embedded delivery, including cleared environments where required.
