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. 

Product Description

The TOE changes consist of:

Updating the firmware running on the Palo Alto Networks WF-500 and WF-500-B appliances from WildFire 10.2 to WildFire 11.0. The updates included new non-security relevant features and bug fixes. The software updates and their effects and relevance are summarized below.


Number of Changes

Applicability to New Firmware Versions

New Features and Feature Enhancements


The software updates of the PAN-OS 10.2 to PAN-OS 11.0 were non-security relevant features and enhancements or features excluded from the evaluated configuration such as: Skip Software Version Upgrade, Intelligent Run-Time Memory Analysis, TLSv1.3 Support for Management Access and Support for OCSP Verification through HTTP Proxy.

Bug Fixes


26 Bug Fixes were made for issues identified in previous releases. The 26 bug fixes break out into the following categories:


12 Performance Improvement

8 Behavior Corrections

6 Outside the Scope of the Evaluation


None of the bug fixes affected the security functionality and none of the changes resulted in changes to the ST or guidance documentation. These changes were either unrelated to SFR testing or were not visible at the level of testing performed for the SFRs. Thus, the original testing still holds, and any fix testing was covered by vendor non-evaluation regression and checkout testing.

CVEs related to PAN-OS affect earlier versions of PAN-OS and do not affect the version on which WildFire 11.0 is based.
