I'm in the process of implementing Sysdig Secure across our containerized environments, with a focus on runtime security and compliance. My goal is to shift security left, so I've integrated the agent into our CI/CD pipelines to scan builds and monitor pipeline activity.
The issue is that Sysdig Secure is currently flagging virtually all traffic originating from our CI/CD nodes as "suspicious network activity." This includes routine connections to our internal artifact repositories, version control systems, and container registries. The alerts are overwhelming my team and creating alert fatigue before we even get to production monitoring. The default policies seem far too broad for a pipeline context.
I understand the principle of zero-trust, but a CI/CD system inherently needs to communicate with trusted internal services. I need to tune the rules to differentiate between legitimate pipeline orchestration and genuine malicious lateral movement.
My specific questions are:
What is the recommended approach for creating exceptions or whitelists for known CI/CD infrastructure within Sysdig Secure's policy engine?
Is there a best practice for structuring policies that are sensitive to the context of a workload—knowing that a pod running a Jenkins agent has different legitimate behavior patterns than a production front-end service?
Have others found that the out-of-the-box network rules require significant modification for real-world pipeline integration, and if so, what was your framework for adjusting them?
Trust but verify — especially the fine print.
Zero-trust doesn't mean "alert on everything." That's just laziness. Your pipeline nodes are a known, tightly-controlled asset group.
Scrap the default policies immediately. Create a dedicated policy scope for your CI/CD namespace or node pool. Then whitelist the egress to your internal artifact repo, VCS, and registry IPs/FQDNs. Sysdig calls them "runtime rules" - you just add allowed processes and destinations.
The "best practice" is to not drown in false positives. Alert fatigue is worse than no alerts.
Exactly. Calling every pipeline connection suspicious is like flagging the office coffee run as a smuggling operation. It's just the supply chain doing its job.
The tricky bit with that whitelist approach, though, is when your CI starts pulling from a new, legitimate external service and you forget to update the runtime rules. You'll get silence, not an alert, and suddenly your builds are failing because you blocked something you shouldn't have. So maybe start with the whitelist, but set up a separate, low-severity audit rule to catch any new outbound calls from the pipeline identity. That way you're not fatigued, but you're also not blind.
