A method, system, or apparatus for mitigating computer and network security deficiencies is provided in which, the method, system, or apparatus scans computer system components for finding a vulnerability, generates a Vulnerability Priority Scoring System (VPSS) score for the vulnerability based on the vulnerability, develops a vulnerability mitigation policy based on a system state comprising the VPSS score, wherein the vulnerability mitigation policy provides a best action for mitigating the vulnerability selected among one or more trained possible actions by a deep neural network, and performs the vulnerability mitigation policy based on the best action. Other aspects, embodiments, and features are also claimed and described.
