Firewall Configuration

The firewall acts as a "gatekeeper", blocking and monitoring unauthorized requests to a network, server, or application. It is crucial that a "gate" (i.e. a port) is closed if it is not actively being used.

A firewall policy that is too lax may allow adversaries to attack internal services.

This BPA test verifies that no excessive ports are open in the Windows firewall.


This BPA is available from DataMiner version 10.2.12 and 10.3.0 onwards. From DataMiner 10.3.7/10.4.0 onwards, this prerequisite runs automatically when you upgrade, to ensure TCP port 5100 is correctly configured to allow inbound communication.
