Our developers rely heavily on third-party images and open-source packages during our build cycles. We are worried about malicious dependencies compromising our cloud build pipelines. What are the definitive steps to protect our infrastructure and maintain strict during automated deployments?

Securing your deployment pipeline requires implementing a strict dependency management strategy. Start by hosting your own private container registry and artifact repository to proxy and cache all approved third-party dependencies. Integrate software composition analysis tools directly into your build steps to automatically scan code for known vulnerabilities and malicious packages. Furthermore, sign your container images using tools like Cosign, and enforce admissions controllers within your production clusters to ensure that only verified, signed images originating from your secure pipeline are allowed to execute.
If we block builds whenever a vulnerability is discovered, won't that slow down our development velocity to a crawl, especially with the high volume of daily open-source updates?
Ensure your build runners utilize ephemeral environments that spin down immediately after execution to prevent persistent malware from taking root.
Ephemeral runners are incredible for minimizing attack vectors. Combining short-lived environments with minimal access privileges keeps your build pipeline incredibly resilient against lateral movement.
You can balance velocity by categorizing vulnerabilities by severity. Only break the build for critical and high risks, while automatically generating tracking tickets for medium and low issues so developers can patch them during regular sprint cycles without halting production deployments.
