| Checkpoint | What it means |
|---|---|
| Service version | Identify software version and patch level |
| Authentication | Check for default or weak credentials |
| SSL/TLS config | Verify encryption settings if applicable |
| Access controls | Test for proper authorization mechanisms |
Mitigation
- Keep software updated
Apply latest security patches - Strong authentication
Use complex passwords and 2FA - Access restrictions
Limit service to trusted networks - Monitor activity
Log and review service usage - Disable if unused
Remove unnecessary services
