I've been evaluating the new runtime drift detection feature over the last few weeks, primarily for a set of containerized applications we manage. The premise is excellent—catching configuration changes in running containers that deviate from the known, approved image state is a critical security control.
From what I've seen, the implementation is quite precise. It effectively tracks changes to files, packages, and even running processes. In my test environment, it immediately flagged a container where a team member had ad-hoc installed a troubleshooting tool via the package manager. That's exactly the sort of unexpected change you want visibility into.
However, I'm curious how others are handling the operational aspect. The volume of data can be significant, especially in dev or staging environments where change is more frequent. I'm starting to think about:
* Creating separate policies for different environments (e.g., stricter in production, more permissive in dev).
* Using the findings to educate teams on immutable infrastructure principles, rather than just as an alerting tool.
* How to best integrate these drift alerts into our existing incident response workflow.
Has anyone else rolled this out more broadly? How are you managing the alert fatigue, and are you using it more for audit/compliance or for real-time blocking? I'm particularly interested in any experiences with the automated remediation hooks.
