Fighting Vulnerabilities With Process, Insight, and Automation
Vulnerabilities are the driving force of cybersecurity research. Despite our best intentions and efforts, vulnerabilities are not going away any time soon. This is because the abstractions and layers we create to manage complexity are unfortunately never perfect. Flaws can occur within each layer and even across layers (e.g., side channels), often breaking our assumptions and reliance on simplifications. Moreover, the diverse types of vulnerabilities make it challenging to come up with universal solutions. Because of the inherent difficulty in eliminating vulnerabilities entirely, in practice, we need a process to cope with them. In this talk, I will discuss my journey in fighting vulnerabilities through the process of vulnerability modeling, discovery, assessment, and remediation. In each task of the process, we are often required to answer questions with binary answers such as "is there a vulnerability?", "is the vulnerability exploitable?", and "is the vulnerability patched?". Even though the answer looks simple, it can be quite difficult to arrive at the right answer. This is because all of these questions require some unique thought process, some way of searching, or insights in general. These insights can come from both academia and the hacking community (e.g., regarding exploitation techniques). We bridge the gap by taking insights from both communities and feeding them into automated solutions. The talk will cover my experience practicing vulnerability research on both novel and known types of vulnerabilities.
