This course provides a detailed overview of the security environment developed for LTE networks, including the LTE Authentication and Key Agreement (AKA) procedures and the provisions for Non-Access Stratum, Access Stratum, Access Network and Core Network security.
Who would benefit
This course is designed for engineers, managers and other personnel who have a need to acquire a technical overview of the security environment employed within LTE networks. It will also be of benefit to those in the wider technical community who have a need to understand the security protocols employed by cellular networks.
Attendance on this course assumes previous attendance on the LTE Engineering Overview course (LT3600) or equivalent basic LTE knowledge. An understanding of legacy 2G and 3G security procedures would be an advantage as would a basic understanding of LTE network architecture and functionality.

- Security threats and mitigations
- 3GPP security strata and the LTE security architecture
- Non-Access Stratum, Access Stratum, Access Network and Core Network Security
- Overall AKA process
