Ensure that 'Include/Exclude Networks' is used if User-ID is enabled

MediumLevel 1Manual reviewpaloalto

Description

If User-ID is configured, use the Include/Exclude Networks section to limit the User-ID scope to operate only on trusted networks. There is rarely a legitimate need to allow WMI probing or other User identification on an untrusted network.

How it is checked

Audit method: Manual review

This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.

Navigate to Device > User Identification > User Mapping > Include/Exclude Networks. Verify that all trusted internal networks have a Discovery value of Include. Verify that all untrusted external networks have a Discovery value of Exclude. Note that any value in the trusted networks list implies that all other networks are untrusted.

How it is fixed

Fix method: Guidance or infrastructure patch

Navigate to Device > User Identification > User Mapping > Include/Exclude Networks. Set all trusted internal networks to have a Discovery value of Include. Set all untrusted external networks to have a Discovery value of Exclude. Note that any value in the trusted networks list implies that all other networks are untrusted.
