A critical component of emergency communications are 911 centers–to include emergency communication centers (ECC), public safety answering points (PSAP), public safety communication centers (PSCC), emergency operations centers (EOC), and other NG911 Transition public safety command centers.

CISA, in conjunction with the SAFECOM-NCSWIC Next Generation 911 (NG911) Working Group, uses stakeholder feedback from multiple levels of government to identify, document, and develop informational products and refine innovative concepts that will facilitate the transition to NG911. This page provides resources and tools to support 911 system operations, security, and NG911 transition.


911 Icon911 centers play an important role in processing 911 calls from the public and dispatching emergency services, including law enforcement, fire, and emergency medical services. These resources provide information on 911 system operations and technologies.

Transition to NG911

NNG 911 IconG911 systems, which operate on an Internet Protocol (IP) platform, enable interconnection among a wide range of public and private networks, such as wireless networks, the Internet, and regular phone networks. NG911 systems enhance the capabilities of today’s 911 networks, allowing compatibility with more types of communication, providing greater situational awareness to dispatchers and emergency responders, and establishing a level of resiliency not previously possible. NG911 will allow 911 centers to accept and process a range of information from responders and the public, including text, images, video, and voice calls. These resources provide information and tools to help 911 stakeholders transition to NG911.

NG911 Self-Assessment ToolSelf Assessment Tool
The NG911 Self-Assessment Tool helps emergency communications centers (ECC) and public safety answering points (PSAP) administrators and oversight personnel evaluate a system’s NG911 maturity state and understand the next steps necessary to continue NG911 deployment progress. The NG911 Self-Assessment Tool is available online at This easy-to-use checklist establishes a common terminology and identifies key milestones to help 911 call centers understand the multi-year NG911 implementation process.

911 Cybersecurity

Cybersecurity 911 centers are often targeted by malicious actors seeking to disrupt 911 operations and their ability to provide live-saving and critical emergency services to the public. These resources provide information on common attack vectors to 911 systems and best practices to mitigate cyber threats, such as ransomware, telephony denial-of-service, and malware attacks.

Cyber Risks to 911: Telephony Denial of Service

This fact sheet familiarizes public safety communications partners with Telephony Denial of Service (TDoS) threats to 911. The document overviews common TDoS attack vectors, highlights real-world TDoS incidents, and suggests best practices to mitigate TDoS impacts.

Cyber Risks to NG911 White Paper
The Cyber Risks to 9-1-1 (NG911) White Paper provides an overview of the cyber risks that will be faced by NG911 systems. It is intended to serve only as an informational tool for system administrators to better understand the full scope and range of potential risks, as well as recommend mitigations to these risks. Developed by CISA in conjunction with the Department of Transportation, the White Paper is an introduction to improving the cybersecurity posture of NG911 systems nationwide.

Protect Your Center from Ransomware PosterPoster

The ransomware poster can be placed in an ECC, PSAP, 911 Call or Dispatch Centers The poster provides information about what ECC staff can do to reduce the risk of ransomware. Although the poster’s focus is on ransomware, its recommendations are applicable across a range of cyber threats like phishing, social engineering and password management. To request an agency or state-specific poster, Statewide Interoperability Coordinators (SWICs) may contact their CISA Emergency Communications Coordinator and/or email the request to Requests should include the following:

    1. Name of State Agency/Dept/Division (Top left side of poster)
    2. High Resolution PNG or JPEG file (Top right corner of poster
    3. Important State Office Contacts (Bottom left corner of poster)( up to three contacts)
    4. FBI Field Office Contact information (Bottom center under Federal Partners)
    5. Point of Contact for the Request (Who can be contacted if additional information is required?)

SWICs may request two printed 20” x 30” copies of the poster and a customized electronic file will be provided for printing additional copies.
