Readers are reminded that the certification of this product (TOE) is the result of maintenance, rather than an actual re-evaluation of the product. Maintenance only considers the affect of TOE changes on the assurance baseline (i.e. the original evaluated TOE); maintenance is not intended to provide assurance in regard to the resistance of the TOE to new vulnerabilities or attack methods discovered since the date of the initial certificate. Such assurance can only be gained through re-evaluation.
Using a security impact analysis of the changes made to the TOE, which was provided by the developer, the CCEVS has determined that the impact of changes on the TOE are considered minor and that independent evaluator analysis was not necessary. A summary of the results can be found in the Maintenance Report, which is written in relation to the product's original validation report and Security Target. Readers are therefore reminded to read the Security Target, Validation Report, and the Assurance Maintenance Report to fully understand the meaning of what a maintained certificate represents.
Changes to the TOE:
Palo Alto Networks WF-500 with WildFire 9.1.8 (hereafter WF-500, i.e., the TOE) is a physical appliance composed of the WildFire functional component hosted on the PAN-OS operating system. PAN-OS, an operating system derived from the Linux kernel version 3.10.88, is used in all Palo Alto Networks next-generation firewalls, Panorama, and the WF-500 product lines. It provides different services to each product line.
The change in the TOE version number from 9.0 to 9.1.8 is due to the release of various patch and feature updates that have taken place since the original WF-500 evaluation in 2020. Those changes were exclusively for the PAN-OS portion of the TOE, where WF-500 is formed from the combination of the WildFire component and the underlying PAN-OS operating system. None of those updates involved changes to WildFire component functionality or its security.
The software changes fell into the following categorization:
The minor changes were collected in two different groups: new features added to PAN-OS, and bug fixes:
· New Features for PAN-OS that are not applicable to the WildFire component and have no impact on the security functionality or the SFRs identified in the WF-500 Security Target, and
· Bug Fixes, also only for PAN-OS, where no changes were made directly to the WildFire component and have no security impact on the WF-500.
