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 specific changes made to the product do not affect the security claims in the Unisys Stealth Solution Release v3.3 Windows Endpoint Security Target.

This update results in no changes to SFRs, Security Functions, Assumptions or Objectives, Assurance Documents and therefore is a minor change. The security target and the Common Criteria Evaluation Guidance Document are updated to reflect the updates.

Test results were produced and found consistent with the previous test results. Finally, the evaluation security team searched the public domain for any new potential vulnerabilities that may have been identified since the evaluation completed.   The search did not identify any new potential vulnerability.

CCEVS reviewed the description of the changes and the analysis of the impact upon security, and found it to be minor. Therefore, CCEVS agrees that the original assurance is maintained for the above-cited version of the product.
