Measure What You FIx: Asset Risk Management Done Right
•
0 likes•851 views
The document discusses improving how organizations measure and prioritize the vulnerabilities they remediate. It proposes moving beyond simple CVSS scores and counting vulnerabilities to developing a model that estimates the likelihood of a vulnerability being breached based on factors like whether it has been actively breached before, has a Metasploit module, entry in ExploitDB, or targets a popular system. This model would allow organizations to focus remediation on the riskiest vulnerabilities first and provide a risk score for each asset based on its highest risk vulnerability. The document criticizes current remediation metrics and aims to help organizations optimize security based on actual data about risk.
