Jan 1, 2025January 2025 — Strengthened security posture and improved maintainability for UML-Cyber-Security/CCDC_Practice_Infrastructure. Delivered Passwd-Pol, a PAM-based Linux password policy enforcement script with dynamic configuration, cross-distro support (yum/apt), and updated usage documentation. Conducted comprehensive documentation improvements across modules (KeyCloak/DNS setup, nix installation, Windows services, Wazuh/Graylog deployment). Addressed quality issues with targeted fixes (SED handling, removal of debugging echoes) to stabilize deployments. These efforts reduce risk, accelerate onboarding, and lower support activities by providing clearer operator guidance and reliable automation.
