The Palo Alto Networks security platform must install updates for application software files, signature definitions, detection heuristics, and vendor-provided rules when new releases are available in accordance with organizational configuration management policy and procedures.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity

Description
Failing to update malicious code protection mechanisms, including application software files, signature definitions, and vendor-provided rules, leaves the system vulnerable to exploitation by recently developed attack methods and programs. The IDPS is a key malicious code protection mechanism in the enclave infrastructure. To ensure this protection is responsive to changes in malicious code threats, IDPS components must be updated, including application software files, anti-virus signatures, detection heuristics, vendor-provided rules, and vendor-provided signatures. Updates must be installed in accordance with the CCB procedures for the local organization. However, at a minimum: Updates designated as critical security updates by the vendor must be installed immediately. Updates for signature definitions, detection heuristics, and vendor-provided rules must be installed immediately. Updates for application software are installed in accordance with the CCB procedures. Prior to automatically installing updates, either manual or automated integrity and authentication checking is required, at a minimum, for application software updates.

Check Text ( C-63463r1_chk )
Since some networks cannot connect to the vendor site for automatic updates, a manual process can be used. To verify that the Palo Alto Networks security platform is using the current Applications and Threats database should be checked by viewing the Dashboard and the version and date compared to the latest release. Go to Dashboard; in the General Information pane, view the Threat Version and Antivirus Version. If they are not the most current version as listed on the Palo Alto Networks support site, this is a finding. The following check applies if the network is authorized to connect to the Vendor site for automatic updates. To verify that automatic updates are configured, Go to Device >> Dynamic Updates If no entries for "Applications and Threats" are present, this is a finding. If the "Applications and Threats" entry states "Download Only", this is a finding.
