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.

Note

This BPA test has been replaced by the Security Advisory BPA test, available from DataMiner 10.3.0 [CU15]/10.4.0 [CU3]/10.4.5 onwards.
