ABSTRACT:
Remote routers are configured to block the return path to malicious websites with the use of split tunneling while allowing paths to third party resource websites. The iBGP protocol runs on the agent's router, advertises routes and enables the head-end to set up a policy at each remote router. Enterprise policies for blocking access to “blackholed” website addresses are centrally administered but third party website traffic is not routed to the enterprise's network resources. Since remote offices may connect directly to third party websites, latency is minimized and network resources at the enterprise are not unduly burdened.
