The PC Security Stack Mappings project aims to enhance corporate PC security by matching existing features with known attack techniques. This approach enables organizations to better understand and address emerging threats.By aligning security features with the techniques described in MITRE's ATT&CK, the project addresses a significant gap between current security measures and real-world attack methods. This alignment allows organizations to improve their defenses and reduce vulnerabilities.While implementation may require significant resources, the benefits of enhanced security posture outweigh the challenges. Organizations must weigh the effort required against the potential risks and consequences of unaddressed vulnerabilities.
