As technology evolves, so must the systems that support critical services. One of the most vital services, the 911 emergency response system, is due for an upgrade. While the traditional 911 system has served us well, its limitations in a world dominated by mobile devices, multimedia, and data-sharing have become apparent. Enter Next Generation 911 (NG911), a digital, more robust version of the legacy 911 system. But while NG911 brings exciting improvements, it also introduces new cybersecurity, privacy, and physical security concerns that must be addressed to protect this essential infrastructure.
What is NG911?
NG911 is a modernized version of the 911 system, built to meet today’s communication demands. Unlike the traditional system, which relies on analog voice calls, NG911 uses Internet Protocol (IP) networks, allowing for a broader range of communication formats, including text messages, images, videos, and data from connected devices. This infrastructure significantly improves the speed, precision, and effectiveness of emergency response efforts.
By adopting IP-based infrastructure, NG911 enables more efficient routing of emergency calls to the appropriate agencies, improving service during peak load times and large-scale incidents. This transformation moves 911 from a simple voice-based service to a more dynamic, data-rich system designed to integrate with modern technology.
Key Differences Between Traditional 911 and NG911
NG911 introduces several key differences from the traditional 911 system, enhancing both the user experience and responder capabilities.
Multimedia Communication: Traditional 911 supports only voice calls. NG911 allows for text, images, and video communication, which can provide emergency responders with critical details that may not be conveyed through voice alone. For example, a person in a dangerous situation can send a photo or video of the scene, helping responders prepare more effectively.
Precise Location Tracking: While traditional 911 systems rely on cell tower triangulation, NG911 leverages GPS and location-based services embedded in mobile devices, making location tracking more accurate. This reduces response time, especially in situations where callers cannot verbally communicate their location.
Data Sharing and Integration: NG911 allows real-time sharing of data between emergency services, hospitals, and law enforcement. For instance, medical information such as allergies or chronic conditions can be sent ahead to hospitals, enabling quicker medical intervention upon arrival.
Scalable and Flexible Infrastructure: Unlike the traditional analog network, NG911 operates on a digital, scalable IP network. This infrastructure is more resilient, allowing for easier upgrades and better integration with future technologies, but it also requires more robust security protocols due to increased cyber risks.
Interoperability: NG911 supports seamless communication between different agencies and jurisdictions, ensuring that information flows smoothly across multiple platforms. This leads to faster coordination during emergencies, but also requires careful management to ensure system security and prevent unauthorized access.
Privacy Concerns in NG911
While NG911 introduces enhanced capabilities, it also brings new privacy challenges. The system’s ability to handle more detailed data, including texts, videos, and personal medical information, raises the stakes for protecting sensitive information.
Collection of Personal and Sensitive Data: NG911’s enhanced multimedia capabilities mean that emergency responders receive more detailed information about a situation, which often includes personal data. Ensuring that this data is collected, stored, and shared only for the intended emergency purpose is crucial. Strict policies must govern who can access and view this information, and encryption should be applied to protect data at all stages of communication.
Data Retention and Storage Policies: Given the volume of data that NG911 can collect, agencies must implement clear retention policies. This includes limiting how long data is kept and ensuring that outdated information is securely deleted to prevent unnecessary privacy risks. Storing large amounts of sensitive data for prolonged periods increases the risk of it being compromised.
Unauthorized Access and Data Breaches: NG911 involves data sharing across multiple agencies, which could increase the risk of unauthorized access. It’s critical to implement robust access control systems to ensure that only authorized personnel can access sensitive information. Multi-factor authentication (MFA), role-based access control (RBAC), and strong user training programs can significantly reduce the risk of a data breach.
Sharing of Data with Third Parties: The ability to quickly share data with third-party emergency services can save lives, but it also presents privacy challenges. Agencies must develop strict guidelines on what types of data can be shared, how it's protected during transmission, and ensure that third parties comply with relevant privacy regulations.
Potential for Surveillance and Misuse: The increased use of location tracking and multimedia data opens the door to potential misuse or surveillance concerns. Public trust in NG911 requires transparency about how data is collected and used, as well as stringent measures to prevent the misuse of this data by unauthorized actors.
Security Risks in NG911
The IP-based infrastructure that makes NG911 so versatile also exposes it to significant security risks. A range of cyber and physical threats must be managed to keep this critical system safe from disruption.
Cyberattacks on Infrastructure: NG911’s digital nature makes it a target for cyberattacks, including distributed denial-of-service (DDoS) attacks, ransomware, and malware. A DDoS attack, for example, could flood the system with traffic, making it inaccessible during critical emergencies. Mitigating these risks requires robust firewalls, intrusion detection systems, and rate-limiting measures.
Data Breaches: With the increased collection and sharing of sensitive personal data, NG911 is highly vulnerable to data breaches. Unauthorized access to medical information, location data, or other personal details could lead to legal and reputational consequences for agencies managing the system. Encrypting all sensitive data and conducting regular security audits are essential to mitigating this risk.
System Interoperability Issues: NG911’s reliance on seamless data sharing between agencies introduces interoperability risks. If one system within the chain is compromised, it could expose vulnerabilities across the entire emergency response network. Ensuring strong security protocols across all systems and agencies is vital.
Physical Disruption of Infrastructure: Physical attacks or natural disasters could disrupt NG911 data centers and communication hubs. Ensuring redundancy, both in data storage and communication channels, is key to maintaining operational integrity in the face of such disruptions. Backup power supplies and geographically distributed servers can provide resilience against these risks.
Cybersecurity Measures to Protect NG911
To effectively mitigate the cybersecurity risks that NG911 systems face, agencies must implement a multi-layered strategy that addresses both existing vulnerabilities and emerging threats. Several critical measures can be put in place to strengthen the security of NG911 systems, ensuring their resilience against cyberattacks.
First, network segmentation is essential. By isolating sensitive NG911 systems from less secure areas of the network, such as administrative databases, the risk of a widespread attack is minimized. Real-time communication channels, such as voice and text transmissions, should be kept separate from other systems to prevent attackers from gaining access to critical infrastructure.
Another key measure is the implementation of threat detection and response systems. Real-time monitoring tools like intrusion detection systems (IDS) and security information and event management (SIEM) platforms allow agencies to detect anomalies in network traffic, such as unauthorized access attempts or unusual data patterns. These systems can automatically alert security teams to take immediate action, reducing the risk of service disruption.
Encryption of sensitive data is critical for safeguarding the personal and medical information transmitted through NG911 systems. All data, whether in transit or stored, should be encrypted using strong protocols like AES-256. This ensures that even if data is intercepted, it remains inaccessible without the proper decryption keys.
Zero-trust architecture offers an additional layer of protection by ensuring that no user or device is inherently trusted. All access requests must be authenticated, and multi-factor authentication (MFA) and role-based access control (RBAC) should be employed to limit access to sensitive parts of the system to only authorized personnel.
Regular security audits and penetration testing are also vital. These processes simulate real-world attacks to identify vulnerabilities before malicious actors can exploit them. Conducting these assessments regularly ensures that security measures remain effective as new threats evolve.
Finally, DDoS protection is crucial for maintaining system availability. Distributed denial-of-service (DDoS) attacks can overwhelm NG911 systems by flooding them with traffic, preventing legitimate users from accessing emergency services. Tools like traffic filtering, rate limiting, and load balancing help mitigate these risks by managing traffic and maintaining service continuity.
Physical Security Measures for NG911
Protecting NG911’s physical infrastructure is just as important as cybersecurity. Key physical security measures should be implemented to secure data centers, communication hubs, and other facilities critical to NG911 operations.
Access control systems are crucial to limiting entry to these facilities. Biometric verification, keycards, and passcodes help ensure that only authorized personnel can access sensitive areas. Continuous surveillance through high-definition cameras and motion sensors allows security staff to monitor for unauthorized activity in real time.
Redundant power supplies and backup systems must be in place to prevent downtime during power outages or network failures. Backup power generators and uninterruptible power supplies (UPS) ensure that essential systems continue to operate if the main power source fails. Additionally, geographically distributed backup sites provide continuity of service in case of localized disasters.
Ensuring disaster resilience by fortifying data centers against natural disasters like floods, fires, or earthquakes is another crucial consideration. Using water barriers, fire suppression systems, and earthquake-resistant construction techniques can help protect physical infrastructure from catastrophic events.
Finally, well-trained physical security personnel are critical. Stationed at data centers and communication hubs, security officers can respond quickly to threats and also help identify insider threats—such as unauthorized employees attempting to access restricted areas

Continuous Monitoring and Risk Management for Securing NG911 Systems
Continuous monitoring is an essential part of any security strategy, especially for NG911 systems that handle sensitive and time-critical information. Implementing continuous monitoring within the framework of recognized risk management standards, such as NIST 800-53, strengthens the overall security posture by aligning processes with industry best practices.
NIST 800-53 provides a set of security controls to protect the confidentiality, integrity, and availability of federal information systems and can be adapted for NG911 infrastructure. Continuous monitoring, as outlined by NIST 800-53, involves the real-time tracking and assessment of the security state of information systems to support ongoing risk management decisions. It integrates security monitoring activities, including automated alerts for potential threats, and helps maintain compliance with established security policies.
For NG911, continuous monitoring ensures that systems remain secure by tracking network activity, detecting vulnerabilities, and providing immediate alerts when anomalous activity is detected. The integration of continuous monitoring with NIST 800-53 controls—such as incident response, system audit logs, and access control—creates a proactive defense against both internal and external threats.
By leveraging NIST 800-53’s guidelines, NG911 operators can automate compliance checks, ensure that encryption and access controls are functioning correctly, and respond rapidly to evolving threats. Furthermore, continuous monitoring under this framework supports the creation of a dynamic, adaptive security environment that adjusts in real time as new risks arise. This enables NG911 agencies to anticipate threats rather than merely reacting to them, enhancing the resilience of emergency response systems.
Safeguarding the Future of NG911
NG911 represents a transformative shift in how emergency services are delivered, providing faster, more accurate, and more flexible communication between the public and emergency responders. However, with this advancement comes the need for robust security strategies to protect the system from both cyber and physical threats.
To ensure the integrity and reliability of NG911, agencies must adopt a multi-layered approach. This includes advanced cybersecurity measures such as network segmentation, encryption, and real-time threat detection, along with strong physical security protocols, including access control, surveillance, and disaster resilience.
