parameters are setup when setting up control policies. Traffic logs record the details of packets such as the
start and stop time of connection, the duration of connection, the source address, the destination address and
services requested, for each control policy. Event logs record the contents of System Configuration changes
made by the Administrator such as the time of change, settings that change, the IP address used to log on,
etc.
