## Description

The Compliance Systems Administrator (Linux / RHEL) plays a critical, hands-on role in securing and maintaining enterprise Red Hat Enterprise Linux (RHEL) and Unix-based operating systems. This position is responsible for the direct technical execution of system hardening, patching, identity integration, and vulnerability remediation to ensure Linux servers and appliances adhere to Department of War (DoW) cybersecurity standards in preparation for CORA cyber inspections.
HOW A Compliance Systems Administrator (Linux) WILL MAKE AN IMPACT, Remediate security findings identified through ACAS/Tenable reports and OpenSCAP scans by performing hands-on system patching, configuration updates, and service hardening on RHEL 8/9 systems.
Technically implement and maintain compliance with Red Hat Enterprise Linux DISA STIGs, Cyber Tasking Orders (CTOs), and IAVM notices.
Configure, troubleshoot, and enforce mandatory access controls using SELinux (Security-Enhanced Linux) in enforcing mode.
Manage and maintain central identity, PAM (Pluggable Authentication Modules), SSSD, and DoW PKI/CAC authentication mechanisms for user and administrative access.
Configure and maintain host-based firewalls (firewalled/iptables) and audit daemon logging (audited) in strict compliance with DoW auditing requirements.
Utilize package management tools (YUM/DNF), Red Hat Satellite, or local repositories to deploy security errata and software updates across air-gapped or restricted networks.
Develop and execute Bash and Ansible playbooks to automate STIG hardening, configuration audits, and compliance validation.
Develop, implement, and document technical mitigation strategies and POA&Ms for system-specific Linux vulnerabilities that cannot be immediately fixed.
Compile technical evidence, OpenSCAP evaluation reports, and configuration artifacts for CORA inspection teams.
