Patent attributes
A system receives a request from a user to execute a command on an air-gapped computer system. If a role-based access control system permits the user to execute the command, the system prompts a number of approvers to determine whether to approve of the user executing the command. If a required number of approvers have approved of the user executing the command, the system encodes the command and incorporates the encoded command in an encoded message. The system uses a simplex communication output device to communicate the encoded message to a simplex communication input device for the air-gapped computer system. The system enables execution of the command by requesting the air-gapped computer system to execute the command, or by providing the user with an access token, received from the air-gapped computer system, which enables the user to physically access the air-gapped computer system and execute the command.
