The public safety community deals with the safety and security of people, property, our institutions, and our country on a daily basis. In the course of their work they access and generate information that is critical to the success of their missions. They expect their communications networks to be reliable, available, and secure. A Public Safety Broadband Network (PSBN) would undoubtedly be a target for cyber-attacks, espionage, and conventional attempts to disrupt and deny the availability of this critical asset to first responders. It is, therefore, imperative that robust measures be taken to secure the network and the information carried over it. This document presents a number of considerations that are structured within a security architecture that serves as a reference for next generation communications networks. The security measures contained in this document are those that are deemed to support the proposed security posture for the PSBN. A security risk assessment would likely identify other security controls that would be required to support the security posture. The consideration statements in this document are derived from similar efforts undertaken in the U.S. to support FirstNet10 and from the experience of subject-matter-experts and practitioners that participated in cross-disciplinary work groups. The Public Safety Broadband Network Use-Cases and User Requirements [1] contains a set of scenarios, referred to as “use-cases,” that typify the way subscribers
