[Editor's Note: Steve Sims just released a brand new advanced course offered by SANS on advanced exploit development. It's amazing and intense stuff. To help people determine whether they have the background skill set to prepare them for the course, Steve wrote a pretty cool little quiz. The brief, 10-question quiz will give you an idea of what you need to know to take the course, and it'll also help you measure your own skills. Check out Steve's description of the course below, take the quiz, and then see how you stack up in preparedness for the course! -Ed.]
As you may have heard, we've just completed a cool new six-day course, "SANS SEC760: Advanced Exploit Development for Penetration Testers". The course was written as a follow-on to "SEC660: Advanced Penetration Testing, Exploits, and Ethical Hacking," for those wanting more knowledge and experience in exploit development. There has been a lot of growth in this area and many organizations are looking for professionals with this skill set in order to perform threat modeling, bug hunting, determine bug exploitability, and possess the ability to write exploits against applications running on modern operating systems. Even if your current position does not have you spending your days writing exploits, the subject matter covered is very relevant for:
- Senior Penetration Testers
- Senior Incident Handlers and Forensics Experts
- Senior Windows Security Professionals (especially those responsible for patch management and selecting tools such as EMET to deploy.)
- Senior Intrusion Analysts (IDS/IPS/AV/Linux/Windows/OSX)
- C & C++ Developers
- Professionals responsible for a Secure-SDLC & SDL process
- Your future position in exploit research!
As the author of the course, I get a lot of questions, including:
- Am I ready for SEC760?
- Should I take SEC660 first?
- I've taken SEC660. Am I definitely ready for SEC760?
- I've taken SEC560. Can I jump right to SEC760 if I only want the exploit dev material?
- I have not taken any SANS pen testing courses, which one should I start with?
- I've taken a course through Offensive Security, is the material the same?
I have written a ten question exam which will hopefully help you with determining if you are better suited for SEC660 or SEC760. Remember that this is purely from an exploit development perspective. SEC660 includes two days of material on introduction to exploit development and bypassing exploit mitigation controls. Much of the other material in SEC660 is on a wide range of advanced penetration testing topics such as network device exploitation (routers, switches, NAC), pentesting cryptographic implementations, fuzzing, Python, network booting attacks, escaping Linux and Windows restricted environments, etc...
Please take the exam without any help. Do not use Google or other search engines to look up answers, ask a peer, or seek the answers by any means other than using your brain and experience. The answers along with explanations are also available in a separate link below. See how you measure up!
You can use the following as a rough guide based on the number of correct answers you achieve on your test.
- 7/10 Correct: You are likely ready to take SEC760, given that you have exploit development experience as listed in the SEC760 course prerequisite section, such as that covered in SEC660.
- 5/10 or 6/10 Correct: This I would consider a grey area where you may require some additional preparation to be successful in the SEC760 class, and again, you must have the exploit development experience as listed in the SEC760 course prerequisite section, such as that covered in SEC660.
- 4/10 Correct or Lower: You are very likely not ready for SEC760 and will really benefit in taking SEC660 first. If you have already taken SEC660 and still scored below a 5/10, it is highly recommended that you work back through 660.4 and 660.5 for a refresh and try again.
Good luck with the quiz, and see you in SEC760!
