Swedish communications regulator PTS said it is beginning scrutiny of telecoms operators' security work to tackle known vulnerabilities of Border Gateway Protocol, which regulates internet traffic dissemination among networks. The aim is to find out whether some of the larger internet operators know enough about the known weak points of BGP and are taking appropriate security measures.
PTS said a number of BGP incidents internationally have to light because of their far-reaching consequences. Some of these were deliberate attacks but others were unintentional configuration errors. If one internet provider suffers a routing problem, this can affect others, but there are established methods to boost BGP safety.
