Abstract Despite well‐defined security models to prevent fraudulent intrusion, a number of security attacks have been reported in literature for legacy networks. While a section of these attacks are due to inherent design limitations, others stem from the pervasive introduction of Internet Protocol (IP)‐based applications and external attacks. The former can be addressed by the continual evolution of the system (as is the case with existing systems) whereas the latter requires careful designing. With the advent of all‐IP next generation mobile network (NGMN) inter‐connecting disparate access technologies, the design process assumes paramount importance in relation to detecting/preventing/eliminating migration of attacks through infected terminals. Taking into consideration the fact that standardization bodies are responsible for individual network evolution, a cooperative NGMN security architecture is proposed in this paper that identifies and isolates/eliminates security attacks. The cooperation is encased by the network elements within the NGMN hierarchy and utilizes an anomaly‐based attack detection mechanism. Several dominant security attacks are simulated to demonstrate the effectiveness of the proposed architecture. Copyright © 2008 John Wiley & Sons, Ltd.
