MediumLevel 1Manual reviewpaloalto

Description

Create a secure Data Filtering profile and apply it to all security policies permitting traffic to or from the Internet. The Data Filtering profile may be applied to security policies directly or through a profile group.

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 Objects > Custom Objects > Data Patterns. Verify that the patterns defined match the various data that you wish to monitor or make blocking decisions on. Navigate to Objects > Security Profiles > Data Filtering For each Filtering Profile, verify that the Data Patterns defined matches the data you wish to monitor, with appropriate values for Alert Threshold (typically 20), Block Threshold (typically 0) and Log Severity. Finally, navigate to Policies > Security. (Full steps: CIS 6.14.)

How it is fixed

Fix method: Guidance or infrastructure patch

Navigate to Objects > Custom Objects > Data Patterns. Add patterns to match the various data that you wish to monitor or make blocking decisions on. Navigate to Objects > Security Profiles > Data Filtering Add a Filtering Profile that matches the data you wish to monitor, with appropriate values for Alert Threshold (typically 20), Block Threshold (typically 0) and Log Serverity Finally, apply the Filtering Profile to a Security Profile. Navigate to Policies > Security. Edit all appropriate policies, and for each Policy choose the Actions tab, and add the appropriate Data Filtering Policy (either as an individual Profile or as part of a Group Profile)
