Routing Security is Vital to the Future
and Stability of the Internet

The Internet is under continuous attack; look at the routing system – not a single day goes by without dozens of incidents. Route hijacking, route leaks, IP address spoofing, and other harmful activities can lead to DDoS attacks, traffic inspection, lost revenue, reputational damage, and more.

How can MANRS  help?

Mutually Agreed Norms for Routing Security (MANRS) is a commitment by network operators around the globe to clean their part of the street and improve the security of the global routing system.

They do this by implementing at least the baseline security efforts defined by MANRS Actions:

  • Filtering – Ensure the correctness of your own announcements and of announcements from your customers to adjacent networks with prefix and AS-path granularity
  • Anti-spoofing – Enable source address validation for at least single-homed stub customer networks, your own end-users, and infrastructure
  • Coordination – Maintain globally accessible up-to-date contact information
  • Global Validation – Publish your data, so others can validate routing information on a global scale
