Protocol Analyzer Modules

The Network Protocol Analyzer is a vital part of the network administration toolbox. Analysis of network protocols is a search for truth in network communications. To find out why a network device works this way, and not otherwise, you should use a protocol analyzer to “live” feel the traffic and extract from it the data and protocols transmitted over the network cable.

The network protocol analyzer can be used to:

• localization of intractable problems;
• detection and identification of unauthorized software;
• obtaining information such as baseline traffic patterns and network utilization metrics;
• identification of unused protocols to remove them from the network;
• generating traffic for penetration test in order to test the protection system;
• work with intrusion detection systems (IDS);
• listening to traffic, i.e. localizing unauthorized traffic using Instant Messaging (IM) or Access Points - (AP) wireless access points;
• studying the work of the network.

If you maintain a network and still don't have a protocol analyzer, it's time to get one.
