Abstract

Methods, non-transitory computer readable media, network traffic management devices and network traffic management systems that provide protection of 5G core networks are illustrated. With this technology, the user plane status can be received from a network repository function indicating whether a user plane restarted. Then the system can determine whether an amount of error messages flowing from the user plane to a gNodeB for a source exceeds a predetermined threshold. In response to determining the amount of error messages exceeds a predetermined threshold and determining that the user plane was not restarted, all messages flowing to the gNodeB for the source can be blocked. Lastly, in response to determining the amount of echo messages from the user plane to the gNodeB is below a second predetermined threshold and that the user plane did not restart, the source can be stored as a bad actor.
