Why We All Need MANRS?

Why We All Need MANRS?

Mutually Agreed Norms for Routing Security (MANRS) is a global initiative, supported by the Internet Society, that provides crucial fixes to reduce the most common routing threats.

Network operators of all sizes can help secure the Internet’s routing infrastructure. By implementing four defensive actions, network operators and Internet Exchange Points (IXPs) can help reduce the most common routing threats.

MANRS outlines four simple but concrete actions that network operators and IXPs should take:

  • 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

This short video helps explain the importance of MANRS to the security and resilience of the global Internet: https://www.youtube.com/watch?time_continue=15&v=nJINk5p-HEE
