Researchers at the University of Texas at San Antonio (UTSA) have conducted a study describing a computer algorithm that ameliorates the effects of spoofed global-positioning system (GPS) attacks on electrical grids and other technologies, which could potentially help cybersecurity professionals better spot and prevent cyberattacks in real time.
"In broad terms, malicious cyberattackers can clone the GPS signal and display, for instance, the wrong time or the wrong location," notes UTSA's David Akopian. "This can wreak all sorts of havoc. It can send people to the wrong location or render hours of data useless."
The team says the new algorithm can identify bogus GPS signals and counter an attack while it happens.
The algorithm also can be applied to cellphones or computers as easily as a new application.
"As we move forward with this concept of driverless cars, it becomes much more vital that we secure our GPS signals," says UTSA's Ahmad F. Taha.
