Routing security is vital to the future and stability of the Internet, and the global MANRS initiative implements the crucial fixes needed to reduce the most common routing threats.

In 2017 alone, 14,000 routing outages or attacks –such as hijacking, leaks, and spoofing –led to stolen data, lost revenue, reputational damage and more, all on a global scale. Operators, enterprises and policymakers have converged around the concrete steps – Mutually Agreed Norms for Routing Security – that prevent these incidents.

Network operators and Internet Exchange Points (IXPs) who implement the MANRS Actions improve both routing security and operational efficiency, clearly signaling a security-forward posture and value-added service.

In seeking MANRS-compliant infrastructure partners, enterprises gain increased security and service reliability, while eliminating common outages or attacks.

Policymakers realize the opportunity to improve infrastructure, decrease malicious activity and stimulate demand by calling for or specifying these MANRS best practices.

MANRS For Network Operators

MANRS comprises simple but concrete steps for network operators that will dramatically improve Internet security and reliability. The first two operational improvements eliminate common routing issues and attacks, while the second two procedural steps provide a bridge to universal adoption and decrease the likelihood of future incidents.

  • Filtering – Ensure the correctness of operator and customer routing announcements 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 in common routing databases
  • Global Validation – Publish routing data, so others can validate routing information on a global scale

MANRS for IXPs

The MANRS Actions were initially designed for network operators, but Internet Exchange Points (IXPs) have an important role in protecting the Internet.

IXPs are important partners in the MANRS community. To address the unique needs and concerns of IXPs, the community has created a related but separate set of MANRS Actions for participating IXPs.

  • Prevent propagation of incorrect routing information
  • Promote MANRS to the IXP membership
  • Protect the peering platform
  • Facilitate global operational communication and coordination
  • Provide monitoring and debugging tools
