Disable Server Response Inspection (DSRI) enabled in security policies for Palo Alto Networks device

Rule Details

Cortex AppSec Rule ID	APPSEC_PAN_4
Category - Subcategory	Public Exposure - Ingress Controls
Provider	OTHER
Severity	MEDIUM
Framework	Ansible

Impact

This rule detects whether Disable Server Response Inspection (DSRI) is enabled in security policies for Palo Alto Networks devices. Enabling DSRI disables the inspection of server responses, potentially allowing malicious content to pass through the network unchecked, thereby reducing security.

How to Fix

Palo Alto Networks

• Resource: panos_security_rule
• Attribute: disable_server_response_inspection

To mitigate this issue, ensure that the disable_server_response_inspection attribute is either set to 'false' or omitted in your panos_security_rule definitions. Disabling DSRI ensures that server responses are inspected, maintaining the efficacy of security policies.

Secure Code Example:

- name: Verify tests
  hosts: all
  connection: local
  tasks:
    - name: Security_rule
      paloaltonetworks.panos.panos_security_rule:
        rule_name: 'Test rule'
        ...
-        disable_server_response_inspection: true

In this example, explicitly setting disable_server_response_inspection to 'false' or omitting it ensures that DSRI is disabled, and that server responses are inspected.
