2.13.6 DSA – Cross Protocol Security

Multiple protocol technologies are available in the network today, for example, 2G, 3G, and 4G. Each Protocol class is solving security issues independently. There is a class of threats that may affect the networks supporting2G/3G and 4G protocols together. The hacker could potentially imitate an MME, sending messages for an IMSI fora Subscriber who is the 2G/3G coverage Area. Similarly, a Hacker can simulate VLR for an IMSI of a Subscriber in the 4G Coverage Area. This solution intends to provide a way to implement security across protocol classes. This solution covers Velocity Check/Time Distance Check.
