Why is it taking so long to secure BGP?
The answer to this question lies in the fact that BGP is a global protocol, running across organizational and national borders. As such, it lacks a single centralized authority that can mandate the deployment of a security solution; instead, every organization can autonomously decide which routing security solutions it will deploy in its own network. Thus, the deployment becomes a coordination game among thousands of independently operated networks. This is further complicated by the fact that many security solutions do not work well unless a large number of networks deploy them.
BGP traffic hijacking is on the rise, according to internet performance metrics analyst firm Renesys, which last year noted that over a period of two months, around 1500 IP address blocks were rerouted. Several were in Australia.
