My work focuses on building (and attacking!) secure systems that users rely on for privacy and autonomy. Users face many threats online today, from 'Big Data'-mining companies that wish to collect and model our online behaviors, to organized criminals that seek financial gain, to even state-level actors and governments that want to control or surveil the communication of their citizens. While there are many tools built to address parts of these and other threats, the game is not over: evolving technologies and increasingly connected devices present new opportunities for attackers to exploit. By studying existing tools and new systems as they emerge, we can help protect users from these threats.

CSCI 4133 - Fundamentals of Computer Security
Primary Instructor
-
Fall 2023
Practice thinking like an attacker by exploring several modern computer security attacks and defenses through hands-on programming projects. Topics include applied cryptography (encryption, authentication), web security (XSS, CSRF, SQL Injection), network security (TLS, MITM attacks), application security (shell injection, buffer overflows), and other current events and trends (government surveillance, botnets, cryptocurrencies). Recommended corequisite: CSCI 4593 (soon to be CSCI 3593). Degree credit not granted for this course and ECEN 4133.
