Amazon Macie reports SSN-like patterns in a municipal 'open data' S3 bucket that is publicly readable. What immediate remediation should architects drive?
Select an answer to reveal the explanation.
Short Explanation
SSNs in a public 'open data' bucket are a siren, not a suggestion. Slam Block Public Access, yank the bad policy, and quarantine the objects before the postmortem. Curiosity browsing can wait until the door is locked.
Full Explanation
Sensitive-data discovery remediation starts with containment: remove public access, correct bucket policies/ACLs, and isolate or re-encrypt/reclassify objects containing regulated identifiers. Accelerating public delivery, ignoring Macie, or widening anonymous read access worsens exposure. After containment, teams investigate how data landed in the bucket and harden prevention (Macie monitoring, Config rules, least-privilege). Continuous improvement treats Macie findings on municipal open-data stores as incident-class events.
