Long-standing vulnerabilities in older wireless broadband standards will continue to dog new 5G networks, despite efforts to improve network security, a new report has claimed.
Researchers with Positive Technologies say that a legacy standard known as GPRS Tunneling Protocol (GTP) is the culprit behind security issues that will leave many of the early 5G networks open to attacks such as spoofing, man-in-the-middle, and denial of service.
Introduced during the earliest upgrades to 2G broadband networks and used through the current 4G standard, GTP allows for data packet transfer between various wireless networks and carriers. For example, if a user is roaming, GTP allows for their calls to be made through a local carrier and handed off to another network.
The idea is to provide an easy way for users to link ..
