LTE Network flaw -part 3

What's the solution?

• The disclosure of the IMP4GT attack comes on the heels of similar research undertaken by academics at Purdue University and the University of Iowa, which uncovered three new security flaws in 4G and 5G networks that can be used to eavesdrop on phone calls and track the locations of cell phone users.
• The incoming 5G standard, which is being rolled out in a handful of countries, aims to offer faster speeds and long-needed security features, including protection from IMSI catchers. But with hundreds of millions of devices impacted by these flaws, it's imperative that 5G implementations apply more robust security and data protection to fix the vulnerabilities.
• "Mobile network operators would have to accept higher costs, as the additional protection generates more data during the transmission," David Rupprecht, one of the paper's co-authors, said. "In addition, all mobile phones would have to be replaced, and the base station expanded. That is something that will not happen in the near future."
• While the scrutiny of the 5G standard has made it possible to catch and fix potential vulnerabilities before the 5G networks are widely deployed, the latest research is a sign that cellular network security needs further attention.
