OCI Security Best Practices for Cloud Guard

All answers to this question.

Start by focusing on the "Critical" and "High" severity alerts first—these are usually things like public buckets or wide-open SSH ports. I would suggest running the Responder Recipes in "Log Only" mode for the first two weeks. This allows you to see exactly what the system would have done without actually interrupting your services. Once you trust the logic, you can enable auto-remediation for non-disruptive tasks like disabling an unused IAM user or deleting an unencrypted block volume.

Have you tried using Security Zones in conjunction with Cloud Guard to prevent these misconfigurations from happening in the first place rather than just detecting them?

• Thomas, Security Zones are a lifesaver. By enforcing strict policies at the compartment level, you can basically block anyone from creating a public bucket or an unencrypted volume. It shifts your security "left" and significantly reduces the noise in your Cloud Guard dashboard. It’s much better to prevent the error than to spend your whole day clearing out hundreds of minor alerts after the fact.

Don't ignore the "Risk Score." It’s a great way to show management how your security posture is improving month-over-month as you remediate those High-severity issues.

• I totally agree. Using the Risk Score trend as a KPI has really helped our team get more budget for security tools because we can prove the actual impact of our work.
