'Ain't Nobody Got Time For That!': Understanding Algorithmic Game Theory and Price of Anarchy

Presented at Diana Initiative 2019, Aug. 10, 2019, noon (60 minutes).

As cyber becomes the new battlefield for the lowest levels of criminal activity, much of our cyber defense posture as a community is built on Anti-Virus (AV) signatures (and other alert based systems), and policy. What do we know about the people/entities we are protecting ourselves against? In this game of cyber chess, how do we know what move to make next? There is a mathematical model of study that is growing in popularity in the Computer Science community called Game Theory. Algorithmic Game Theory could help advance algorithmic systems to identify malicious activity BEFORE it affects a network (being proactive vs reactive) by using strategic decisions based on the interactions of rational decision makers. But what about negligence in following policy as a kind of insider threat? Price of Anarchy (PoA) is a subset of Game Theory that analyzes and attempts to measure how much a system can be degraded by selfish behaviors.

This talk is for everyone looking to crack the egg of cyber defense and stop the Whack-A-Intrusion game and asks how we can use Game Theory to create proactive solutions in the technical and psychological realm of cybersecurity. We will discuss what Game Theory is, how it is being used today in Cybersecurity, and then attempt to apply a non-cyber principle (PoA) to further calculate if the changes we are making in cyber defense is actually helping us become more secure (or if it is just lip service). This talk will NOT tell you the best AV to use. The purpose is to show you a different way of thinking about defense decision making, down to the employee/policy level.

  • Vanessa Redman
    Vanessa Redman is a long time listener, first time speaker at a cyber conference. She considers herself a researcher first and foremost, and has interests in open source information gathering and adversary tactics and techniques. She is particularly interested in cyber threat intelligence and how to integrate algorithmic game theory to create a *proactive* defensive framework that can be easily specialized and used across the community. Her view of cybersecurity fundamentally changed while working for a Red Team, and she strongly believes that being able to think like a malicious actor is a key component in building a robust defensive posture. She holds a CompTia Security + certification, in currently finishing her B.S. in Computer Science, and is scheduled to take the GXPN Certification in the Fall of 2019.
