Interview › Security & DevSecOps
How would you embed security scanning into a pipeline without making it slow? [Advanced]
Answer
I embed security scanning without slowing the pipeline by using staged scanning, caching, incremental analysis, parallel jobs, risk-based blocking, and asynchronous deep scans. Fast checks run on every PR; heavier scans run on nightly builds or release candidates.
Technical explanation
Pre-commit and PR checks should be fast and high-signal.
Dependency and container scanners should use caches and scan only changed artifacts where possible.
The policy should differentiate between block-now findings and notify/remediate findings.
Hands-on example
Pipeline pattern: PR runs secret scan, SAST incremental analysis, SCA on changed manifests, and IaC checks in parallel. Build runs image scan with cache. Staging runs DAST. Nightly runs full repo and deep dependency scans. Only critical reachable issues block immediately.
