Nordic authorities collaborating on measures against vulnerabilities in networks

The Norwegian Communications Authority (Nkom) and its sister authorities in the four other Nordic countries have issued joint recommendations on measures against vulnerabilities in electronic communications networks. The aim is to close security holes that have been identified in the discussion about security on mobile networks.

In concrete terms, the measures target Signalling System no. 7 (SS7), which is a system for the exchange of call control information in the networks. The system has been in use since the 1970s. Over the past year, it has been demonstrated how vulnerabilities in SS7 can be exploited, particularly on mobile networks. To meet this challenge, the Nordic telecommunications authorities have collaborated on common recommendations for operators that own and operate mobile networks. The companies themselves have contributed actively during the work on these recommendations.

"This is the first time we have collaborated in this way, and our experience so far has been very positive," says Einar Lunde, Deputy Director of Nkom's Networks Department.

"Several of the mobile companies have networks in several countries in the Nordic region, and we believe the operators will benefit from joint Nordic recommendations. Norway and the Nordics are world leaders in the use of electronic communications, meaning we must also lead the way in making the networks more secure. The purpose of these recommendations is more secure networks," says Lunde.
