Sounil Yu

The Katz School’s cybersecurity program is hosting a virtual talk on “Cyber Defense Matrix for Protecting Your Enterprise” by Sounil Yu, chief information security officer in residence at YL Ventures and creator of the groundbreaking cyber defense matrix, on Monday, Oct. 12, at 6:30 p.m. on Zoom.

Yu developed the cyber defense matrix as a framework for rationalizing technologies, measuring control coverage and effectiveness, identifying control gaps, optimizing resource allocation and organizing security design patterns. Elements of it have been incorporated into the Center for Internet Security’s Top 20 Critical Security Controls, and the matrix has been adopted by the OWASP Foundation, a nonprofit that works to improve the security of software.

In a career spanning more than three decades, Yu has been granted 22 patents covering a wide range of topics, including threat modeling, graph databases, intrusion deception, endpoint security monitoring, tracking media leaks, attributing malicious requests and devices to organizations, detecting logic bombs, security portfolio optimization, and neutralizing stolen files.

In addition, he developed the DIE Resiliency Framework, which advocates for three new paradigms for how to secure systems. The old paradigm focuses on confidentiality, integrity and availability, or what is known as the CIA Triad. The new paradigm focuses on building systems to be distributed, immutable and ephemeral, or the DIE Triad.

Yu helped improve security at several institutions, as chief security scientist at Bank of America and at other Fortune 100 companies. He also created and led a nationally recognized intern program with over 300-plus students to build new capabilities and tackle tough challenges in cybersecurity. In addition to having certifications as an information systems security professional (CISSP) and in security essentials (GSEC), Yu holds a master’s degree in electrical engineering from Virginia Tech and bachelor’s degrees in electrical engineering and economics from Duke University.
