In the public sector, a defacement is a highly visible incident with strong reputational impact. The key metric is exposure time: the longer the change stays live, the higher the chance of amplification and loss of trust.
Detection
Integrity monitoring identified homepage modifications and triggered an alert with the observed change. This enabled action without waiting for user reports.
Response
The IT team restored the site from backup and validated integrity quickly.
Key takeaways
- Integrity monitoring reduces defacement exposure time.
- Context-rich alerts accelerate response (what changed and where).
- Backups and runbooks are essential to restore within minutes.
