SANS SEC660, Advanced Penetration Testing, is an intensive, hands-on program that trains security professionals to attack and evaluate complex networks, operating systems, and applications. Through in-depth modules on network exploitation, post-exploitation, fuzzing, Python/Scapy scripting, and modern Windows/Linux exploitation techniques, learners build practical offensive skills and real-world toolchains. The course emphasizes labs and bootcamps that simulate enterprise scenarios, culminating in Capture-the-Flag exercises that test applied proficiency.
