Polycom 1500/1800/2000/4000 manual Ultra Secure Mode, Network Intrusion Detection System Nids

Administration and Utilities

The data collected is saved into a single compressed file containing all the information from each system component in its relative format (.txt, .xml, etc.). In case the disk is malfunctioning, the file will be written to the RAM (involves only a small amount of information where the RAM size is 1/2 a gigabyte). The zipped file (info.tgz) can be opened with the following applications: WinRAR and WinZip. The entire zipped file is then sent to Polycom’s Network Systems Division for analysis and troubleshooting.

Ultra Secure Mode

The Information Collector logs information from the Collaboration Server’s Network Intrusion Detection System (NIDS), saving it into a compressed disk file. (If the disk malfunctions, the file is written to RAM.) The zipped file (info.tgz) can be opened with either WinRAR or WinZip. The entire zipped file can be sent to Polycom for analysis.

Network Intrusion Detection System (NIDS)

The Collaboration Server system uses iptables for access control. For each different kind of packet processing, there is a table containing chained rules for the treatment of packets. Every network packet arriving at or leaving from the Collaboration Server must pass the rules applicable to it.

Depending on the nature of the suspect packets, the rules may reject, drop, or limit their arrival rate (dropping the rest).

The Collaboration Server maintains a log that includes all unpermitted access attempts blocked by the fire wall.

Unpermitted access includes:

●Access to ports which are not opened on the Collaboration Server.

●Invalid access to open ports.
