The Internet Society’s Mutually Agreed Norms for Routing Security (MANRS) initiative is designed to provide measures to improve the resilience and security of the internet’s routing infrastructure to keep it safe for businesses and consumers.
While the internet was first envisioned as a way of enabling robust, fault-tolerant communication – the global routing infrastructure that underlies it is relatively fragile. A simple error like the misconfiguration of routing information in one of the >10,000 networks central to global routing can lead to a widespread outage, and deliberate malicious actions, like preventing traffic with spoofed source IP addresses, can lead to distributed denial of service (DDoS) attacks.
The Internet Society (ISOC), a non-profit organisation that promotes the open development, evolution and use of the Internet and the parent organisation of the Internet Engineering Task Force (IETF) standards body, are actively working to change this underlying frailty. In 2014, ISOC introduced its Mutually Agreed Norms for Routing Security (MANRS) initiative. Today the membership has grow from its initial 9 network operators to >100 today.
