Public Safety Land Mobile Radio Communications Security

Reliable land mobile radio (LMR) communications are the backbone of public safety operations and key to mission success. The ability of responders to communicate and coordinate efforts during routine and emergency operations is the dominant factor in saving lives and protecting property.

In recent years, Communications Security—COMSEC—has become an important element in the public safety environment. COMSEC focuses on the security of all elements of public safety communications, from the infrastructure of voice and data systems to communications facilities, radios, smartphones, tablets, and computers, as well as policies and procedures governing radio traffic. This document focuses on the security of LMR systems, assets, and communications, with an emphasis on securing radio traffic with encryption.
