Vulnerability Remediation Simulator for APT Management

This document is a technical report on the Vulnerability Remediation Simulator, which displays recorded, unremediated vulnerabilities categorized by critical exploits used by MITRE Advanced Persistent Threats (APTs). The simulator allows administrators to identify vulnerabilities that, when remediated, will significantly reduce the exploitable attack surface. It includes features such as simulating remediation actions and showing the impact on various attack groups. The report details how the simulator integrates with vulnerability scan data from tools like Tenable and Qualys, guiding users on applying the best patch and configuration settings. Additionally, it introduces the concept of Protection Level Agreements (PLAs) to measure and track cyber risk reduction. The document emphasizes the importance of collaboration between IT and Security Operations to expedite vulnerability remediation and improve overall cyber resilience. It also discusses the BigFix CISA Known Exploited Vulnerability Exposure Analyzer, which helps identify urgent security issues based on CISA's catalog of critical threats.
