I've been running vulnerability scans on our container images as part of our CI/CD pipeline, but it's generating way too many alerts. Between high, medium, and low severity findings across our base images, dependencies, and custom layers, it feels impossible to prioritize what needs immediate attention. We spend more time triaging these alerts than we do fixing real issues, and I'm worried that some critical vulnerabilities might slip through the cracks amidst all the noise.
We're using tools like Trivy integrated into our build process, but the volume of alerts is overwhelming, especially since we frequently rebuild images for different environments. I'm curious how other teams handle similar situations. Do you filter alerts based on exploitability scores or tie them to runtime behavior in your clusters? Also, how do you integrate these alerts into your overall observability setup to make them more actionable? Would love to hear about real-world strategies from teams that manage heavy container workloads. Thanks!

Start by classifying your assets, then match them with CVSS scores or severity ratings of the findings. Tackle it from the top down. Also, maybe you can get the container users involved in vulnerability remediation? From what you've shared, it sounds like this is a DevOps environment, so it might be best for developers to be responsible for their container security instead of solely relying on sysadmins.
We managed to reduce noise by setting up custom policies in Trivy to only flag vulnerabilities relevant to our environment. Using a Software Bill of Materials (SBOM) also helps clarify our dependencies. Have you thought about integrating Trivy with Open Policy Agent (OPA) to automate enforcement of security policies?
We found that switching to lightweight base images made a significant difference. We were wasting too much time on false positives, and it was impacting our productivity. Once we trimmed the images and used lighter alternatives, the alerts became more relevant and pointed directly to real issues.
Just focusing on CVE scores can be misleading. You should combine the severity of the vulnerability with the context of the system affected. For example, prioritize a high-severity issue on a critical system over a critical issue on something less important, like a cafeteria lunch board. Consider factors like availability, exposure to the outside world, and the sensitivity of the data being processed. Some tools like Tenable try to account for these factors, but don’t overlook the specific context of your systems when scoring vulnerabilities.
