Prerequisite Quantitative Risk Assessment and Adjustment of Cyber-Attack Robustness for a Computer System

Abstract:

Aspects of the disclosure relate to assessing and adjusting robustness to cyber-attacks of a computer system. The capability of defending against cyber-attacks by cyber-tools (via protection methods) is mapped to one or more attack vectors. One or more cyber-tools may be activated based on the capability mapping. Based on protection data generated by the computer system, an assessment computing device determines a cyber-robustness metric for the one or more cyber-tools and may invoke a reconfiguration of the cyber-tools to increase the cyber-robustness of the computer system. A machine learning machine may process the protection data, such as log data, to detect one or more patterns to determine an effectiveness of the activated cyber-tools. With some embodiments, the machine learning machine groups the protection data using a subset of variables and forms meta structures from the subset.
