CVE-2024-49138

Overview 

The Cybersecurity and Infrastructure Security Agency (CISA) has recently updated its Public Safety Communications and Cyber Resiliency Toolkit, adding seven new resources aimed at enhancing the resilience and security of public safety communications across the nation. This update comes as part of CISA’s ongoing effort to support public safety, national security, and emergency preparedness communities in ensuring seamless and secure communications during both everyday operations and emergency situations. 

Public safety agencies rely heavily on communication systems to coordinate responses and deliver critical services. Any disruption in these communication systems can have disastrous consequences, delaying response times and potentially compromising lives. For this reason, Cyber Resiliency is a key focus for public safety organizations, which need to ensure that their communication networks can withstand and recover from cyberattacks and other disruptions. 

CISA’s toolkit is designed to support public safety agencies in supplementing these capabilities. It provides tools to assess current systems, identify vulnerabilities, and implement strategies to protect the infrastructure against online threats, including cyber incidents, ransomware, and even natural disasters like electromagnetic pulse (EMP) events. 

Recent Updates to the Public Safety Communications and Cyber Resiliency Toolkit 

As of December 2024, the toolkit has received its latest update—Version 24.2—which includes seven new resources. These resources have been specifically designed to help public safety agencies address emerging challenges in communications resilience and cyber security. The update is timely, as it follows the release of new CISA guidelines and continues the agency’s efforts to provide the most up-to-date information to the public safety sector. 

The toolkit now features resources addressing critical issues such as: 

  • Cybersecurity and Cyber Incidents: The toolkit now includes enhanced guidance on protecting communication systems from cyberattacks, including the rising threat of ransomware. With ransomware attacks becoming more sophisticated, public safety agencies need resources that help them prevent, respond to, and recover from these types of incidents. The toolkit provides a comprehensive Cyber Resiliency strategy that emphasizes preparedness and swift recovery. 

  • Next Generation 911 (NG911): NG911 represents the future of emergency communications, enabling more advanced features such as text-to-911, multimedia messaging, and real-time data sharing. However, NG911 systems also come with increased vulnerabilities. The updated toolkit includes new resources focused on securing NG911 systems and preventing cyber risks that may target them. For example, the Cyber Risks to Next Generation 911 guide is designed to familiarize public safety managers with the risks associated with NG911 and offers best practices to improve cybersecurity in these systems. 

  • Power and Infrastructure Dependencies: Power disruptions and dependency on critical infrastructure are persistent challenges for public safety agencies. The updated toolkit includes resources like the Infrastructure Dependency Primer, which helps planners better understand the complex web of dependencies that can impact community resilience. By identifying and mitigating potential weaknesses in critical infrastructure, public safety organizations can strengthen their overall Cyber Resiliency. 

  • Electromagnetic Pulse (EMP) and Jamming: Both EMP and radio frequency (RF) jamming can significantly disrupt public safety communications, especially during emergencies. The toolkit now provides updated guidance on how to protect communication systems from these emerging threats. The Radio Frequency Interference Best Practices Guidebook offers public safety organizations practical advice on recognizing, responding to, and mitigating the effects of jamming and interference. 

Key Resources in the Toolkit 

The Public Safety Communications and Cyber Resiliency Toolkit has become an important tool for public safety agencies across the country, offering resources that cover a wide range of critical topics: 

  1. Resiliency Planning: Tools such as the Infrastructure Resilience Planning Framework help state, local, tribal, and territorial governments develop effective strategies to identify vulnerabilities and build resilient communication networks. This framework is crucial for ensuring that public safety agencies can maintain their operations during both normal and emergency conditions. 

  1. Priority Services and Telecommunications: The Priority Telecommunications Services section offers detailed information on how public safety agencies can ensure priority access to communication networks during times of crisis. Services such as Wireless Priority Services (WPS) and Government Emergency Telecommunications Service (GETS) enable emergency personnel to maintain communication when networks are overloaded. 

  1. Cyber Resiliency for Public Safety: The toolkit includes resources designed to help agencies assess their cybersecurity posture. The Cyber Resiliency Resources for Public Safety document, for example, compiles tools and programs from federal agencies, industry, and trade associations to help agencies improve their cybersecurity defenses. This resource is especially valuable in light of increasing cyber threats targeting critical infrastructure. 

  1. Public Safety Communications Ecosystem: The toolkit offers an interactive graphic that outlines key components of the emergency communications ecosystem, helping users understand the interplay between various systems and technologies. This visualization aids public safety officials in recognizing potential vulnerabilities in their networks. 

  1. Procurement and Vendor Guidance: New documents, such as the Connected Communities Procurement and Implementation Guidance, provide public safety leaders with questions to ask when selecting vendors. These resources ensure that vendors’ products and services align with the public safety agency’s cybersecurity policies and operational needs. 

A Living Document 

One of the most valuable features of CISA’s Public Safety Communications and Cyber Resiliency Toolkit is its ability to evolve in response to new threats and emerging technologies. As new resources are developed and identified, the toolkit is regularly updated to reflect the latest best practices and recommendations for public safety agencies. 

Since its last major update in April 2024, CISA has added several key resources, highlighting the agency’s commitment to providing public safety agencies with the tools they need to protect their networks and systems. Users are encouraged to revisit the toolkit regularly to ensure they are leveraging the most current and relevant information available. 

Conclusion 

The Public Safety Communications and Cyber Resiliency Toolkit remains an indispensable resource for public safety agencies seeking to protect their communication systems against cyber threats. 

By using the toolkit, agencies can better prepare for the challenges of today and tomorrow, ensuring that they remain resilient in the face of natural disasters, cyberattacks, and other disruptions.  

For more information, public safety officials and decision-makers are encouraged to explore the CISA toolkit and make use of the new resources now available in Version 24.2.
