"In this paper, we describe the Capture-the-Flag (CTF) activity and argue that it contributes to a necessary component of the computer security curriculum. This component is the study of software vulnerability investigation. It is currently not properly emphasized in this curriculum. We discuss reasons for this situation and we go on to describe how CTF can be useful for educating students within this focus. CTF helps develop those computer security skills that enable students to identify new vulnerabilities before those with malicious intent find them. It also helps them to hone the core computer security skills."
