Course insights:

Penetration testing is done to identify potential threats and gaps in the security and network system of an organisation which is then analysed to patch up the detected vulnerabilities and reinforce security.

This course gives students a practical chance of assessing the security of a VoIP infrastructure by securely trying to exploit vulnerabilities that exist. In this course, we’ll look for active VoIP user accounts, record ongoing conversations and then simulate a fake VoIP call using a SIP account of any valid user.

VoIP is one of the fastest growing technologies and is receiving lots of attention from service providers and users due to its cost and flexibility. Students who enroll in this course will get an understanding of how to setup a VoIP network and then analyze it for vulnerabilities.
