## Troubleshooting
|
|
|
|
### No audit reports generated
|
|
|
|
Check report directory exists:
|
|
```bash
|
|
ls -la ./reports/security_audit/
|
|
```
|
|
|
|
### Failed checks
|
|
|
|
Review specific failed checks:
|
|
```bash
|
|
ansible-playbook playbooks/security_audit.yml -vv
|
|
```
|
|
|
|
### Permission denied
|
|
|
|
Ensure become is enabled:
|
|
```bash
|
|
ansible-playbook playbooks/security_audit.yml --become
|
|
```
|
|
|
|
## Integration with CI/CD
|
|
|
|
```yaml
|
|
# GitLab CI example
|
|
security_audit:
|
|
stage: compliance
|
|
script:
|
|
- ansible-playbook playbooks/security_audit.yml
|
|
only:
|
|
- schedules
|
|
```
|
|
|
|
## Best Practices
|
|
|
|
1. **Schedule regular audits** - Run weekly or after changes
|
|
2. **Review reports** - Don't just run audits, act on findings
|
|
3. **Track trends** - Compare audit results over time
|
|
4. **Document exceptions** - Note why certain checks fail
|
|
5. **Remediate findings** - Create tasks to fix issues
|
|
|
|
## Quick Reference Commands
|
|
|
|
```bash
|
|
# Dry-run audit
|
|
ansible-playbook playbooks/security_audit.yml --check
|
|
|
|
# Verbose output
|
|
ansible-playbook playbooks/security_audit.yml -vvv
|
|
|
|
# Specific environment
|
|
ansible-playbook -i inventories/production playbooks/security_audit.yml
|
|
|
|
# Multiple tags
|
|
ansible-playbook playbooks/security_audit.yml --tags "selinux,firewall,ssh"
|
|
|
|
# Skip specific checks
|
|
ansible-playbook playbooks/security_audit.yml --skip-tags packages
|
|
```
