Interview › Security & DevSecOps
What is the CISA KEV catalog, and how would you use it? [Intermediate]
Answer
The CISA Known Exploited Vulnerabilities catalog is a list of vulnerabilities that CISA identifies as known to be exploited in the wild. I use it as a high-confidence signal for urgent remediation, especially for internet-facing or business-critical assets.
Technical explanation
KEV status means exploitation is not theoretical; defenders should treat it as a strong prioritization signal.
Federal agencies have required timelines for KEV remediation, and private organizations often use it as a best-practice input.
KEV should feed asset inventory, vulnerability scanners, ticketing, patch SLAs, and executive risk reporting.
Hands-on example
Hands-on: ingest the KEV JSON feed daily. Join it with vulnerability scan results by CVE. If a KEV appears on an exposed production asset, create a P1 ticket, notify the service owner, apply patch or mitigation, and verify by rescan.
