PacketHound Gets New Tracking Abilities
New version of Palisades Systems' security and monitoring appliance features enhanced reporting and tracking abilities.Palisades Systems Inc. on Tuesday introduced a new version of its PacketHound security and monitoring appliance, adding new reporting and tracking capabilities. The appliance operates in passive mode and sits in the network traffic flow, monitoring inbound and outbound connections, much as a firewall does. The difference is that PacketHound uses a database of signatures to look for application usage instead of monitoring TCP ports the way that firewalls do. The appliance will find and block applications or protocols that the administrator has identified as undesirable. It does so by injecting into the traffic flow a reset packet, which then closes the offending connection. The system can also allow certain types of traffic through and then kill the connection once the traffic reaches a certain bandwidth threshold.
The idea is to cut down on bandwidth costs and security risks produced by users connecting to file-sharing networks, Web sites that deliver streaming media and other potentially time-consuming applications.
