## About KEV

The CISA Known Exploited Vulnerabilities (KEV) catalog contains vulnerabilities that:

- Have been assigned CVE IDs
- Have been actively exploited in the wild
- Have clear remediation actions

**Reference**: [CISA KEV Catalog](https://www.cisa.gov/known-exploited-vulnerabilities-catalog)

---

## Why KEV Matters

1. **Prioritization**: Not all CVEs are equally critical
2. **Active Exploitation**: KEV focuses on vulnerabilities being actively used by attackers
3. **Compliance**: US federal agencies required to patch KEVs within specified timeframes
4. **Risk Reduction**: Addressing KEVs provides immediate security improvement
