Security Audit Playbook Cheatsheet
Quick reference for using the security audit playbook.
Quick Start
# Run full security audit on all hosts
ansible-playbook playbooks/security_audit.yml
# Audit specific environment

# Audit specific host
ansible-playbook playbooks/security_audit.yml --limit hostname
Common Usage
Full Audit
# Complete security audit with all checks
ansible-playbook playbooks/security_audit.yml
# Production environment only
ansible-playbook -i inventories/production playbooks/security_audit.yml
Selective Audits
# SELinux and AppArmor only
ansible-playbook playbooks/security_audit.yml --tags selinux,apparmor
# Firewall configuration audit

Troubleshooting
No audit reports generated
Check report directory exists:
ls -la ./reports/security_audit/
Failed checks
Review specific failed checks:
ansible-playbook playbooks/security_audit.yml -vv
Permission denied
Ensure become is enabled:
ansible-playbook playbooks/security_audit.yml --become
Integration with CI/CD
# GitLab CI example
security_audit:
stage: compliance
script:
- ansible-playbook playbooks/security_audit.yml
only:
- schedules
Best Practices
- Schedule regular audits - Run weekly or after changes
- Review reports - Don't just run audits, act on findings
- Track trends - Compare audit results over time
- Document exceptions - Note why certain checks fail
- Remediate findings - Create tasks to fix issues
