If vulnerabilities in 4G cellular networks that can expose them to denial-of-service and other attacks are not addressed, emerging 5G networks could inherit these same issues, the security firm Positive Technologies reports.
The firm’s new research report, which looked at the security 4G LTE networks in Europe, Asia, Africa and South America in 2018 and 2019, found weaknesses in the diameter-signaling protocol, which can leave these networks open to DoS attacks as well as other cyberthreats.
