Maximizing Cybersecurity Effectiveness: Leveraging CISA’s KEV List for Smarter Threat Management
Understanding the Known Exploited Vulnerabilities (KEV) Catalog
Cybersecurity teams should view the Known Exploited Vulnerabilities (KEV) Catalog from the Cybersecurity and Infrastructure Security Agency (CISA) as a valuable resource, rather than a cause for panic.
The KEV Catalog is Often Misunderstood
According to Tod Beardsley, VP of Security Research at runZero and former section chief for KEV at CISA, the catalog is often misunderstood.
Maximizing the Benefits of the KEV Catalog
To maximize the benefits of the KEV catalog, Beardsley recommends combining it with other data sources, such as the Common Vulnerability Scoring System (CVSS), the Exploit Prediction Scoring System (EPSS), and exploit tooling data. This multi-faceted approach allows teams to make more informed decisions about patching priorities.
By adopting a more nuanced understanding of the KEV catalog and incorporating it into a broader vulnerability management strategy, organizations can improve their overall security posture and reduce the risk of exploitation by threat actors.
