4.2.5 Establishing connection - detection

The Personal firewall detects each newly-created network connection. The active firewall mode determines which

actions are performed for the new rule. If Automatic mode or Policy-based mode is activated, the Personal firewall

will perform predefined actions with no user interaction. Interactive mode displays an informational window which

reports detection of a new network connection, supplemented with detailed information about the connection. You

can opt to allow the connection or refuse (block) it. If you repeatedly allow the same connection in the dialog window,

we recommend that you create a new rule for the connection. To do this, select the Remember action (create rule)

option and save the action as a new rule for the Personal firewall. If the firewall recognizes the same connection in the

future, it will apply the existing rule without requiring user interaction.

Please be careful when creating new rules and only allow connections which are secure. If all connections are allowed,

then the Personal firewall fails to accomplish its purpose. These are the important parameters for connections:

Remote side – Only allow connections to trusted and known addresses.

Local application – It is not advisable to allow connections for unknown applications and processes.

Port number – Communication on common ports (e.g., web traffic – port number 80) should be allowed under

normal circumstances.

In order to proliferate, computer infiltrations often use the Internet and hidden connections to help them infect remote

systems. If rules are correctly configured, a Personal firewall becomes a useful tool for protection against a variety of

malicious code attacks.

4.2.6 Logging

The ESET Endpoint 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 ESET Personal firewall log from the Log drop-down menu.

The log files are a valuable tool for detecting errors and revealing intrusions into your system. ESET Personal firewall

logs contain the following data:

Date and time of event

Name of event

Source

Target network address

Network communication protocol

Rule applied, or name of worm, if identified

Application involved
