Sophisticated attacks require real time intrusion detection and analytics

Mobile network security is on top of the operators’ agenda and is discussed extensively at network security conferences and other industry events. This is partly due to the fact that security threats and attacks are increasing in numbers and becoming more and more sophisticated. At a recent international Network Security Conference, a range of topics around mobile network security policy were thoroughly discussed. The overriding impression was, though, that the network security issue seemed to be focused almost purely on the end devices and the security around these. Little was mentioned regarding the implications of moving from a circuit switched network to an all IP network and thus the exposure of the VoIP/IMS network to new security issues.
