Polycom®, Inc. 748
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.
