Aspects of the disclosure relate to systems and methods of improving keyboard, video, and mouse (KVM) security on blocking KVM privilege request. A management device includes a processor and a non-volatile memory storing computer executable code. The computer executable code, when executed at the processor, is configured to: establish a first KVM session for a management device in response to a first privilege request; provide options of KVM authorities; select one of the options based on a first user instruction; and upon receiving a second privilege request requesting for a second KVM session, perform a first operation based on the selected one of the options.
