It is currently under the command of the 690 Cyberspace Operations Group, which is responsible for operating and maintaining the United States Air Force's global enterprise network. The 561 NOS mission is to operate the cyberspace security and control system (CSCS) weapon system to deliver mission assurance. The 561 NOS and 690 COG report to the 688th Cyberspace Wing, which is currently under the Sixteenth Air Force.

Emblem.
The emblem was originally designed for the 2161st Communication Squadron, a predecessor of the 561 NOS. Polaris, the guiding star and light, allude to Air Force Communications Command communicators who provide the medium for obtaining and providing guidance to all Air Force activities through communications systems. The star also symbolizes the NATO mission, thus, the close coordination with our Allies. The ellipses signify the elements of the atom, the basis of all electronic/electrical equipment that the 2161st Communication Squadron operated and maintained. This is the macrocosm view. In the macrocosm, the ellipses represent the earth and the global-wide communications (connectivity) which the 2161st Communications Squadron provided. The lightning bolt indicates the transmission and reception of signals by the communications equipment and is symbolic of Air Force Communications Command. The blue background indicated the United States Air Force primary theater of operations, the sky. The original emblem was approved in 1983 and was revised 17 October 2018
