Every network manager should be concerned with reducing the risks of security breaches and network failure. The trouble is both kinds of problems can be difficult to diagnose. The evidence you need to solve them often occurs over the course of days or weeks, and traditional network analysis tools, which are typically designed to show you what's happening in real time, provide a much narrower window on events. Two appliances from Network Associates aim to fill in the gap by combining one of the company's old standbys, the Sniffer network analysis tool, with the ability to capture and store terabytes of network traffic. InfiniStream Network Management, a new product, allows you to mine historical, packet-level data to solve network problems. InfiniStream Security Forensics, released last July, brings historical data to bear in the investigation of security issues and network misuse. In taking a historical approach to network and security analysis, these solutions compete with similar appliances from Niksun.
