General Information

Course description

This course covers advanced techniques for writing exploits and patching vulnerabilities, taught through an intense, hands-on security laboratory. A significant part of this course involves solving Capture-The-Flag (CTF) and discussing strategies for solving such problems. This course covers a variety of topics including (but not limited to) reverse engineering, exploitation, binary analysis, and web.

Grading policy

  • 100% Lab.
  • If you didn’t turn in a single (full) lab, you will get an F.
    • You have to submit AT LEAST one flag per lab.
    • Solve the tutorial counts. If you solve all tutorials in all labs, you will not get an F.
  • 40%: A, 30-40%: B, 30-20%: C and below (in each group).
    • Refer to Canvas for grading policy per lab.
  • No midterm or final exams.
  • We provide a week of a grace period (50% points after due date).
  • See Game Rules.

Online Discussion

Online discussion is strongly encouraged and it will help you a lot in solving lab problems. Please join Piazza and post your questions, ideas and thoughts.

Misconduct Policy

CS6265 provides one week of a grace period (50% points after due date) and we strictly follow the cheating policy (read GT’s Academic Misconduct Policy).


Cheating vs. collaboration

Collaboration is a very good thing. On the other hand, cheating is considered a very serious offense and is vigorously prosecuted. Vigorous prosecution requires that you be advised of the cheating policy of the course before the offending act.

For this semester, the policy is simple: don’t cheat:
  • Never share code or text on the project.
  • Never use someone else’s code or text in your solutions.
  • Never consult project code or text that might be on the Internet.
On the other hand, for this class, you are strongly encouraged to:
  • Share ideas.
  • Explain your code to someone to see if they know why it doesn’t work.
  • Help someone else debug if they’ve run into a wall.

If you obtain help of any kind, always write the name(s) of your sources.


Don’t publish or post your work online (e.g., github). Any violation of these rules would result in F in your grade.
