Abstract

Disclosed is a computerized system for determining the collective effectiveness of information security technologies. The system typically includes a processor, a memory, and an information security analysis module stored in the memory. The system for is typically configured for: determining a security score for each element of a security technology defense matrix, a first dimension of the security technology defense matrix corresponding to a plurality of resource classes, and a second dimension of the security technology defense matrix corresponding to a plurality of security operational functions; determining a defense-in-depth score for each resource class and each security operational function; determining an aggregate security score; and providing the aggregate security score the defense-in-depth scores for each resource class and each security operational function to a user computing device. The system may be configured to provide technology deployment recommendations. Based on such recommendations, additional security technologies may be deployed.
