Filtering Methods

An NBA policy can use the following methods to detect filter data packets:

Filtering by protocol

Network filters can detect TCP or UDP packets, or both. Application filters can detect packets sent using a range of IM, Webmail, email or file transfer protocols, such as POP3, YAHOOIM, or HTTPPOST; see Application protocols.

Filtering by IP address and TCP port

All filters can detect packets sent from specified IP addresses or transmitted to specified TCP ports. For example, you can configure filters to ignore SMTP data from corporate email servers if that data is already being captured by CA DataMinder.
