Are legacy technologies a threat to EU’s telecom infrastructure?

Telecommunications is a key infrastructure based on how our society works. It constitutes the main instrument that allows democracy and EU core values such as freedom, equality, rule of law and human rights to function properly. There are currently over 5 billion unique mobile subscribers and over 2000 mobile operators worldwide. In Europe, there are 456 million unique mobile subscribers, which is equivalent to 84% of the population.

Mobile networks worldwide are still depending on SS7 and Diameter for controlling communications (routing voice calls and data) as well as on sets of protocols that were designed decades ago without giving adequate effect to modern day security implications. In this respect, the interconnected environment has become perilous. “In this context, ENISA has developed a study, which has examined a critical area of electronic communications: the security of interconnections in electronic communications, also known as signalling security. An EU level assessment of the current situation has been developed, so that we better understand the threat level, measures in place and possible next steps to be taken,” said Udo Helmbrecht, ENISA’s Executive Director.
