Mobile devices, such as smartphones and tablets, communicate with these cells via a radio base station that generates a radio frequency signal between the two. Like 4G networks, 5G networks will leverage macro towers - providing radio coverage served by a high power cell site - however, they will also require small cells, which will serve as signal repeaters for devices to provide improved speed. 5G networks are comprised of several key components. As part of this national strategy, a 5G Threat Model Working Panel was established, which released the joint analysis paper on Monday.ĥG decreases power requirements for devices and offers improved network performance - including 100 times faster download speeds over 4G, according to CISA. In August, CISA released the National Strategy to Secure 5G, which outlined step-by-step measures for rolling out 5G, assessing and addressing the security risks of 5G infrastructures and promoting “responsible global development” of 5G networks. carriers like AT&T, Verizon and T-Mobile build out 5G strategies, and smartphone manufacturers like Apple and Samsung offer devices with 5G compatibility, government officials have been mulling over how to proactively secure 5G networks. “Given these threats, 5G networks will be an attractive target for criminals and foreign adversaries to exploit for valuable information and intelligence.”Īs major U.S. The deployment of 5G can “introduce significant risks that threaten national security, economic security, and impact other national and global interests,” according to the analysis. However, 5G has also sparked security concerns, highlighted this week in a joint analysis by the Cybersecurity and Infrastructure Security Agency (CISA), National Security Agency (NSA) and Office of the Director of National Intelligence (ODNI) on the potential threat vectors inherent in 5G infrastructure. The fifth-generation technology standard for broadband cellular networks has long been touted as a gamechanger for the connectivity levels needed for emerging applications, including Internet of Things (IoT) devices, smart cities and autonomous vehicles. As the rollout of 5G networks accelerates, government officials are voicing concerns around the security of the deployments, in a new analysis that highlights supply-chain threat vectors and vulnerabilities on legacy infrastructure implementations.
