Firewall logs
The ESET Endpoint Security for macOS firewall saves all important events in a log file. To access firewall logs from the main menu, click Tools > Logs and then select Firewall from the Log drop-down menu.
Log files are a valuable tool for detecting errors and revealing intrusions into your system. ESET firewall logs contain the following data:
•Date and time of the event
•Name of the event
•Source
•Target network address
•Network communication protocol
•Rule applied
•Application involved
•User
A thorough analysis of this data can help detect attempts to compromise system security. Many other factors indicate potential security risks and can be defended against using a firewall such as: frequent connections from unknown locations, multiple attempts to establish connections, unknown applications communicating, or unusual port numbers.
