ESET Personal Firewall Log

The personal firewall incorporated in ESET Smart Security saves important events in a log file, which can be viewed directly from the main program menu. Click Tools > Log files and then select ESET personal firewall log from the Log drop-down menu..
The log files are an invaluable tool for detecting errors and revealing intrusions into the system, and should be given appropriate attention. ESET personal firewall logs contain the following data:

date and time of event
date and time of event
source and target network address
network communication protocol
rule applied, or name of worm, if identified
application involved

A thorough analysis of this data can help detect attempts to compromise system security. Many other factors indicate potential security risks and allow the user to minimize their impact: too frequent connections from unknown locations, multiple attempts to establish connections, unknown applications communicating, unusual port numbers used.
