The ESET Internet Security Personal firewall saves all important events in a log file, which can be viewed directly from the main menu. Click Tools > Log files and then select Personal firewall from the Log drop-down menu.

The log files can be used to detect errors and reveal intrusions into your system. ESET Personal firewall logs contain the following data:

Date and time of event

Name of event


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 you to minimize their impact: frequent connections from unknown locations, multiple attempts to establish connections, unknown applications communicating or unusual port numbers used.
