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

There have been no changes to the product or development environment.


The evaluated TOE includes models with Keyboard-Mouse (KM) switching functionality only; i.e. no switching of video display. Most KVM models of the TOE can also be set to a “KM mode” that disables the video ports and causes the TOE to operate as if it was a KM device only. In these cases, the selected computer can be switched by one of two methods:


·         Push-button toggles on the TOE hardware to switch to the desired computer

·         Moving the mouse cursor to the edge of the screen on the selected computer to switch to the ‘next computer over’ (note that since the TOE does not have any displays connected to it while in this configuration, the conditions for switching are detected by the (x,y) coordinates of the mouse)


The TOE includes a “multi-head display mode” option where cursor-controlled switching cannot be engaged until the user has first pressed the center mouse button (scroll wheel) twice. In the original evaluation, “multi-head display mode” is described as a voluntary option within the administrative guidance. In order ensure the T.UNINTENDED_SWITCHING threat from the PP is properly addressed, this Assurance Maintenance Continuity was completed to enforce “multi-head display mode” as mandatory for the CC evaluated configuration for KM models, or when KVM models are configured in KM mode.


The Security Target (ST) and Administrative Guidance have been updated to instruct administrators/users that “multi-head display mode” switching is required for the evaluated configuration for KM models of the TOE, or when a KVM model is configured in KM mode.
