SS7 EXPLAINED

“The Tech Infrastructure, Challenges and Opportunities”

About this Lesson

SS7 is a set of protocols allowing phone networks to exchange the information needed for passing calls and text messages and ensure correct billing. It also allows users on one network to roam on another, such as when traveling in a foreign country.

This lesson provides a fundamental look at both the SS7 protocol (along with GSM MAP) and related security issues and provides valuable insights into SS7 protocol.
