Ensuring Internet traffic is reliably routed around the world is a critical building block for a trustworthy, global Internet. Based on common network operational practices in place today, the global Internet routing system does not have sufficient security controls to prevent the injection of false routing information, including impersonation of networks. The lack of these controls creates a significant vulnerability of the entire system. The result is thousands of incidents of misrouted traffic or denial of service on a global scale each year.
The Mutually Agreed Norms for Routing Security (MANRS) initiative, which has been fostered by the Internet Society, overcomes this collective problem by establishing a security baseline of concrete actions for network operators. These actions are supported by a growing and visible community of more than 200 networks around the world that have adopted them.
