Citizens Broadband Radio Service (CBRS)
Risks and Threats
What is Citizens Broadband Radio Service?
Citizens Broadband Radio Service (CBRS), is a cellular network technology operating in the 3.5 GHz to 3.7 GHz frequency band. CBRS is used across various industries for IoT, logistics, healthcare, and more, due to its efficient use of spectrum and support for critical applications. The discussion covers the three-tier spectrum sharing framework of CBRS, its comparison to WiFi, applications, security risks like man-in-the-middle attacks, and strategies for securing CBRS networks, highlighting the importance of this technology in modern wireless communication.

Threats and Vulnerabilities to CBRS
CBRS is susceptible to risks such as IMSI catchers or stingray attacks, man-in-the-middle attacks, denial of service attacks, downgrade attacks, and protocol exploits in cellular networks. These vulnerabilities allow attackers to intercept, alter communications, track devices, and disrupt service by exploiting weaknesses in cellular protocols and security measures, particularly as Internet of Things (IoT) deployments increasingly utilize CBRS over traditional Wi-Fi networks.
How do we protect against CBRS risks and threats?
LOCH secures CBRS networks through a multifaceted approach involving intrusion detection, prevention systems, and a new strategy emphasizing software-defined radio technology. This technology, particularly within our AirShield product, leverages AI and ML to analyze risks and threats on the 3.5 GHz to 3.7 GHz frequency band, crucial for CBRS. It underscores the importance of continuous monitoring and the identification of vulnerabilities in wireless networks, especially in IoT and critical infrastructure environments, providing a comprehensive defense strategy against potential breaches and compromises.
