also be blocked. UDP protocols such as RTSP and RTP are monitored and
logged.
The Quota feature is an alternative to full blocking. It gives employees time
each day to visit sites in categories you deem appropriate. Quotas can be a
powerful tool for internet access management. Quotas help you control how
much time your employees spend on personal surfing and the types of sites
they are able to access. For more information, see the Administrator's Guide
for Websense Enterprise and Web Security Suite.
The Protocol Management feature allows Websense software to filter internet
protocols other than HTTP. This includes protocols, applications, or other data
transfer methods such as those used for instant messaging, streaming media,
file sharing, file transfer, internet mail, and various other network or database
operations. You must install Network Agent to use protocol management.
If you have a subscription that includes the Bandwidth Optimizer module and
have installed Network Agent, your Websense software can filter internet
sites, protocols, or applications based on available network bandwidth. You
can specify filtering settings to limit user access to sites, protocols, or
applications based on bandwidth usage.
If you have a subscription that includes the Instant Messaging (IM)
Attachment Manager and have installed Network Agent, you can configure
your Websense software to restrict file attachment sending and file sharing
with IM clients. This feature enhances the default IM controls in Websense
Enterprise and Web Security Suite by allowing you to permit certain IM
traffic while blocking the transfer of attachments by those IM clients.
