Mobile Network Vulnerabilities and Pentesting

Cyber security digital concept

This workshop introduces participants to penetration testing methods and principles for Sigtran / MAP-based and Diameter-based signaling systems in mobile networks.

Participants will gain insights 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.

This course is intended for experienced network engineers, network tuning staff and anyone with network experience who are keen to identify mobile network vulnerabilities and to acquire skills and knowledge to defend mobile networks against attacks.

Instructor-Led Training
[Classroom: 3 days / LIVE Virtual*: 21 hours]
*Note:
  • A minimum of 5 or more participants are required for a company-based LIVE Virtual course to commence
  • LIVE Virtual courses can be conducted for 5 hours or 7 hours daily. Please note that the number of training days will be extended if you opt for 5 hours daily.
