Disable: 'User Account Control: Only elevate executables that are signed and validated' for ValidateAdminCodeSignatures This policy setting enforces public key infrastructure (PKI) signature checks for any interactive applications that request elevation of privilege. Enterprise administrators can control which applications are allowed to run by adding certificates to the Trusted Publishers certificate store on local computers. The options are: - Enabled: Enforces the PKI certification path validation for a given executable file before it is permitted to run. - Disabled: (Default) Does not enforce PKI certification path validation before a given executable file is permitted to run. Counter Measure: Enable the UserAccount Control: Only elevate executables that are signed and validated. Potential Impact: Enabling this setting requires that you have a PKI infrastructure and that your Enterprise administrators have populated the Trusted Root Store with the certificates for the allowed applications. Some older applications are not signed and will not be able to be used in an environment that is hardened with this setting. You should carefully test your applications in a pre-production environment before implementing this setting. For information about the steps required to test application compatibility, make application compatibility fixes, and sign installer packages to prepare your organization for deployment of Windows Vista User Account Control, see Understanding and Configuring User Account Control in Windows Vista (http://go.microsoft.com/fwlink/?LinkID=79026). Control over the applications that are installed on the desktops and the hardware that is able to join your domain should provide similar protection from the vulnerability addressed by this setting. Additionally, the level of protection provided by this setting is not an assurance that all rogue applications will be found"
