An adversary may use legitimate desktop support software to establish an interactive command and control channel to target systems within networks. Desktop support software provides a graphical interface for remotely controlling another computer, transmitting the display output, keyboard input, and mouse control between devices using various protocols. Desktop support software, such as VNC, Team Viewer, AnyDesk, ScreenConnect, LogMein, AmmyyAdmin, and other remote monitoring and management (RMM) tools, are commonly used as legitimate technical support software and may be allowed by application control within a target environment.(Citation: Symantec Living off the Land)(Citation: CrowdStrike 2015 Global Threat Report)(Citation: CrySyS Blog TeamSpy)
Remote access modules/features may also exist as part of otherwise existing software such as Zoom or Google Chrome’s Remote Desktop.(Citation: Google Chrome Remote Desktop)(Citation: Chrome Remote Desktop)

Comments
This control describes how CSPs and CSCs must install, update, and properly configure endpoint and software-defined firewalls, regularly review and approve firewall rule changes, and monitor traffic for anomalies and malicious code. These mitigative actions help prevent unauthorized access, block threats, and ensure only approved firewall rules are active.
