Cyber Defense Matrix — The Cyber Defense Matrix helps us understand what we need organized through a logical construct so that when we go into the security vendor marketplace, we can quickly discern what products solve what problems and be informed on what is the core function of a given product. In addition, the Cyber Defense Matrix provides a mechanism to ensure that we have capabilities across the entire spectrum of options to help secure our environments.
Cyber Defense Matrix Reloaded — This is an update to the Cyber Defense Matrix briefing given at the 2019 RSA Conference. Cybersecurity practitioners can use this to organize vendors, find gaps in security portfolios, understand how to organize security measurements, prioritize investments, minimize business impact, visualize attack surfaces, align other existing frameworks, and gain a fuller understanding of the entire space of cybersecurity.
