Course Objectives:This workshop aims at introducing penetration testing methods and principles for Sigtran/MAP-based signaling systems in mobile networks. During the course participant will gain insight into the signaling protocol related network vulnerabilities by actively using the Kali-Linux pentesting tools, modified and extended for mobile networks environment. Practical exercises and lecturer guided signaling trace analysis will provide a strong foundation for further studies in the field.
Pre-requisite for Participants:Participants should have a basic understanding of SS7/Sigtran-based signaling protocols and procedures used in mobile networks core network environment. A working-level knowledge in Linux environment is recommended for the practical exercises. Some basic knowledge in C++ and Python is an added advantage.
