PROFILE
Alan Moore
Alan Moore engineered security compliance automation for the ComplianceAsCode/content repository, focusing on Ubuntu hardening and cross-distro maintainability. Over 14 months, he delivered features such as SSHD drop-in rules, PAM policy enforcement, and CIS profile migration, using Bash, Ansible, and YAML to streamline configuration management and testing. Alan’s work included developing remediation logic, expanding test automation, and aligning package management for Ubuntu 22.04 and 24.04, addressing both system security and deployment consistency. His technical depth is evident in the integration of OVAL checks, AppArmor enforcement, and network filtering, resulting in robust, auditable, and scalable security policy implementations.

Oct 1, 2025Month 2025-10: ComplianceAsCode/content delivered targeted security hardening and cross-version compatibility improvements. Key features delivered across Ubuntu 22.04 and 24.04 include PAM version alignment, nftables-based network filtering enablement, generalized /var/log remediation across Ubuntu versions, and AppArmor mode enforcement. A notable bug fix corrected a Jinja macro logic condition to ensure configurations apply only when product compatibility requires it. These changes reduce deployment risk, improve consistency across distributions, and strengthen system hardening, while maintaining maintainability through generic platform definitions.

Jan 1, 2025January 2025 Monthly Summary for ComplianceAsCode/content Overview: Delivered a comprehensive CIS Ubuntu 24.04 hardening suite focused on password policy, PAM configuration, root/GID hardening, time synchronization governance, path integrity, and robust testing automation. The work emphasizes business value by reducing risk of credential compromise, ensuring consistent security controls across deployments, and enabling auditable CIS alignment. Key features delivered: - CIS 5.3.x password policy rules implemented across ubuntu2404 (no_empty_passwords, login failure lockout, unlock time, root password quality, strong hashing, and pam faillock), including ensuring pam_unix uses a strong hashing algorithm. - PAM configuration and packaging improvements: added package applicability for pam, removed unnecessary nullok retention, cleaned up Priority lines, and implemented broader PAM policy hardening. - Oval checks and root GID hardening: added oval check to prevent any other user from primary group 0, improved accounts_root_gid_zero test, and added rule to ensure root remains the only GID 0 account. - PAM enhancements: added accounts_password_pam_unix_no_remember rule, implemented 5.3.3.4.2 to prevent pam_unix remember, and rewrote remediation/tests to use pam-auth-update for pwhistory remember; expanded test scaffolding and test coverage. - Time synchronization and path hardening: enforced a single time synchronization daemon (2.3.x family), implemented time service rules, and introduced root path/directory hardening (no_dirs_unowned_by_root, root_path_all_dirs, accounts_root_path_dirs_no_write, root_path_no_dot). - Testing and CI improvements: test infrastructure improvements, pam-auth-update usage in tests, skip confirmation automation, and CI/test housekeeping to improve reliability and reduce flaky tests. Major bugs fixed: - Fixed nullok_present.fail.sh in no_empty_passwords tests. - Reverted pam-auth nullok removal changes to avoid breaking existing parameters. - Reverted removal of the additional Priority line. - Removed a duplicate OVAL check to streamline validation steps. - Fixed minor typos in remediation text and comments. Overall impact and accomplishments: - Significantly improved CIS compliance posture for Ubuntu 24.04 across multiple domains (password policy, PAM, time services, path integrity). - Reduced risk of credential compromise and misconfig by hardening root and administrative controls and standardizing validation through OVAL checks. - Enabled consistent, auditable security configurations across environments with automated testing and CI integration. Technologies/skills demonstrated: - PAM configuration and policy management, PAM: pam_auth_update workflows, pwhistory management, and faillock integration. - CIS Benchmark alignment, OVAL validation, and root/GID hardening. - Scripting and automation for tests, CI/QA automation, and containerized/deployment-friendly configurations. - Time synchronization governance (ntp/chrony) and path ownership hardening.
