Overview: We propose integrating the Exploit Prediction Scoring System (EPSS) score into RHACS. This addition will enhance our ability to assess and prioritize vulnerabilities based on the likelihood of exploitation, improving our overall security posture.

Current Challenge: Our current system relies on traditional vulnerability metrics, which often do not provide a clear indication of the actual risk posed by a vulnerability. This can lead to inefficient allocation of resources, where critical vulnerabilities may be overlooked while less severe ones receive undue attention.

Proposed Solution: Integrate the EPSS score into our vulnerability management system to complement existing metrics. The EPSS score is designed to predict the likelihood of a vulnerability being exploited in the wild, providing a more nuanced and actionable risk assessment.

Benefits:

1. Improved Risk Prioritization: EPSS scores will help prioritize vulnerabilities more likely to be exploited, ensuring that critical issues are addressed promptly.
2. Resource Optimization: By focusing on vulnerabilities with higher EPSS scores, we can allocate our resources more effectively and efficiently.
3. Enhanced Reporting: EPSS scores will provide additional insights into our vulnerability reports, offering a more comprehensive view of our security landscape.
4. Proactive Security Measures: Anticipating potential exploits allows for more proactive measures, reducing the likelihood of successful attacks.
