SPs could provide the answer to combatting DDoS attacks according to BT, providing customers with DDoS mitigation at a price far cheaper than buying it in directly.

According to Mick Creane, Head of Managed Security Strategy at BT, ISPs are in a unique position to be able to make DDoS mitigation affordable for its customers, and it's something BT is already considering. 'We're looking at technology in the core of our network that would direct traffic through a "scrubbing centre". This terminates requests, checks if they are valid and if they are not, drops them. Where they are valid, they are forwarded to the original destination,' said Creane. 'It's expensive, but with BT you have economies of scale. So we would divert traffic as necessary [rather than route everything through the "scrubbing centre"].'
