Description
Without the ability to immediately disconnect or disable remote access, an attack or other compromise taking place would not be immediately stopped. VMM remote access functionality must have the capability to immediately disconnect current users remotely accessing the VMM and/or disable further remote access. The speed of disconnect or disablement varies based on the criticality of missions functions and the need to eliminate immediate or future remote access to organizational VMMs. The remote access functionality (e.g., RDP) may implement features, such as automatic disconnect (or user-initiated disconnect), in case of adverse information based on an indicator of compromise or attack.
