Public Safety Communications Resiliency: Ten Keys to Obtaining a Resilient Local Access Network
Ten Keys to Obtaining a Resilient and Route Diverse Local Access Network helps organizations mitigate threats to communications continuity and supports resilient, “always available communications.” This document presents ten key steps organizations can follow to determine if local network infrastructure communication paths are sufficiently diverse to minimize communications outages.
Public Safety Communications Resiliency Guidebook
Complete end-to-end network resilience is difficult to achieve, but an organization can greatly improve “always available” communications by identifying and mitigating resilience issues through a self-assessment of its local access network. The Public Safety Communications Network Resiliency Self-Assessment Guidebook provides instructions on how to assess resiliency of a public safety communications network, describes common critical resiliency gaps in public safety networks, proposes mitigation solutions for assured communications in stressed network environments, and demonstrates a proven methodology for data gathering, connectivity mapping, and analysis. CISA ECD recommends use of the Guidebook for organizations performing resiliency self-assessments of their critical facilities.
Resiliency Fact Sheet
The Resiliency Fact Sheet introduces the topic of communications continuity, and discusses the importance of network resiliency. The Fact Sheet provides the available resources to (1) establish a process to assess threats and vulnerabilities to communications networks, (2) enable organizations to conduct self-assessments and (3) identify mitigation solutions. It also conveys the benefits of performing a resiliency self-assessment.
