IPsec profile uses insecure authentication algorithms on Palo Alto Networks devices misconfiguration

Rule Details

Cortex AppSec Rule ID	APPSEC_PAN_12
Category - Subcategory	Public Exposure - Encryption And Protocols
Provider	OTHER
Severity	MEDIUM
Framework	Ansible

Impact

This rule detects whether IPsec profiles in Palo Alto Networks devices use insecure authentication algorithms. Specifically, the rule checks that IPsec profiles do not use 'none', 'md5', or 'sha1' for ESP (Encapsulating Security Payload) authentication, as these algorithms are considered weak and vulnerable to attacks. Strong authentication algorithms are crucial for ensuring the confidentiality and integrity of IPsec VPN connections.

How to Fix

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:

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. [source,go]

• 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
