How To Handle Data Breaches In A CMS
AdvancedQuick Answer
TL;DR
When a CMS data breach occurs, immediately contain the breach by revoking compromised credentials and API tokens, isolating affected systems, and preserving evidence. Assess the scope — what data was accessed, how many users affected, and what regulations apply. Notify affected parties and regulators within required timeframes (72 hours for GDPR). Remediate the vulnerability that was exploited, restore from clean backups if needed, and conduct a post-incident review to prevent recurrence.

- Contain immediately: revoke tokens, reset passwords, isolate affected systems
- Assess scope: what data was exposed, who is affected, which regulations apply
- Notify: inform affected users and regulators within required timeframes
