As Mobile Telecoms open their infrastructure to IP networks and the entire world outside the modern communications phenomenon becomes as susceptible to security threats and performance challenges as any other traditional network. The need for monitoring and inline threat detection is as vital to the security and performance of the network as it is to the perceived quality and competitive advantage of the Telco organization.

While malicious malware propagates the radio network and vulnerabilities in the core weaken performance, the requirement for IDS and Analyzer solutions are extensive and continually growing as technologies evolve. The use of VSS monitoring's Distributed Aggregator Taps which leverage a scalable bank of monitoring servers over multiple networks of different speed and type creates vast performance advantages as well as ROI and cost-benefit awakenings throughout the Telco industry.

The above diagram shows how a mobile network infrastructure can be monitored to achieve deployment and operating cost reductions as well as immediate response times to troubleshooting and security incidents.

Mobile network operators have been accustomed to proprietary systems and closed networks. With the deployment of GPRS and UMTS networks, they are now confronted by an unfamiliar world of open systems and vast open networks, where anyone with a PC or mobile device has easy access to the hardware, software, and knowledge needed to compromise security and disrupt communications.

In order to monitor effectively and ensure security as well as comply with relevant regulations mobile carriers are implementing network taps to support failsafe and simultaneous monitoring of IDS and analyzer tools.

Network Taps & Distributed Solutions
Considering the extent to which new 3G systems in the Telco environment need to be failsafe and secure from outside threat the choice of network tap over any other data collection method is of critical importance. As 3G analyzers are expensive and the need to capture data from multiple locations is extensive, the only real cost effective solution is a distributed tap that centralizes the monitoring servers. This further supports the simultaneous deployment of monitoring tools.

VSS monitoring's distributed data collection tools are changing the architecture of network monitoring. The deployment of these tools enables inline monitoring as well as capture of all available data from span ports throughout the core and distribution networks. This enables a distributed data collection systems that centralizes the monitoring servers creating widespread network visibility while reducing the cost of those server deployments. Analyzers, IDS and Forensics tools are especially expensive when deployed in the distributed architecture suggested by those vendors. These costs are experienced through hardware, software licenses and annual maintenance of each. The VSS monitoring distributed taps enable the convergence and simultaneous usage of these tools while radically reducing their costs.
