Second is the ability to detect and analyze application-layer traffic and generate alerts according to network operator-defined rules. For example, application tunneling that would otherwise circumvent port-based firewall rules can be detected, allowing the operator or service provider to take appropriate action.

Third is the ability to selectively capture traffic based on the existence of keywords or other patterns of bytes. This enhanced interception capability aids network operators and law enforcement agencies in investigating criminal activity and fighting terrorism.

Fourth, NarusInsight has significantly expanded capability to monitor and analyze the ever-growing volume of traffic on carrier and government networks. Multiple petabytes of traffic can be processed, correlated and analyzed in a single system in real time. The highly scalable architecture provides a cost-effective solution for typical deployments today and an efficient growth path as networks continue to expand in size and performance.

Narus also added the following analysis and integration enhancements to NarusInsight:

Customizable reporting structure for creating customer-specific analytics

An open interface for integration with virtually any mitigation device an operator may want to use to act on the anomalies reported by NarusInsight

Support for integrating with third-party alert reporting and management tools, such as ArcSight

"Service providers and government contractors must ensure their networks are protected against malicious cyber attacks and meet government regulatory requirements," said Les Niles, vice president, product management, Narus. "We worked closely with our customers to ensure we deliver a highly customizable real-time traffic intelligence solution. The enhanced NarusInsight enables our customers to protect against network attacks and unwanted traffic, expand the precision targeting capabilities for lawful intercept, and meet their scalability requirements, including full support for 10 Gb networks. We are pleased to announce today the newest version of NarusInsight."

NarusInsight is the foundation for the industry's most advanced real-time cyber protection, intercept and traffic management solutions. Beginning with ubiquitous collection directly from network links or from existing network elements such as routers and firewalls, and moving through a massively scalable processing engine, NarusInsight has the ability to simultaneously provide deep-packet analysis, full session reconstruction and traffic correlation across every link and every element on the network. Regardless of the consuming application and whether the information required is based on full packets, application-layer metrics or basic flow-level information, NarusInsight captures and processes the information in real time in a single network-wide system. With NarusInsight's capabilities to "see" traffic from the network through the application layer, Narus is in a unique position to help its customers understand their traffic. Once they understand the traffic, the NarusInsight Solutions for Cyber Protection, Intercept and Traffic Management allow them to protect and manage their networks, and to comply with governmental regulations.
