SANS SEC660, Fortgeschrittenes Penetration Testing, is an intensive, hands-on program that trains security professionals to attack and assess 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 develop practical offensive skills and real toolchains. The course emphasizes labs and boot camps that simulate enterprise scenarios, culminating in capture-the-flag exercises that test applied competence.
