Online Course: Mutually Agreed Norms for Routing Security

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

The Mutually Agreed Norms for Routing Security (MANRS) is a global initiative, supported by the Internet Society, to work with operators, enterprises, and policymakers to implement crucial fixes needed to eliminate the most common routing threats.

Routing outages or attacks – such as hijacking, leaks, and spoofing – lead to stolen data, lost revenue, reputational damage and more, all on a global scale. MANRS addresses these concerns.

MANRS comprises four simple but concrete steps 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.

Course Objectives

  • Explain the databases and repositories MANRS participants should use to document routing information, and maintain contact information.
  • Learn how to enable others to validate route announcements originating from your network by documenting a Network Routing Policy.
  • Discuss the basics of implementing filters within your network to prevent propagation of incorrect routing information.
  • Provide guidance on applying anti-spoofing measures within your network to eliminate traffic with spoofed source IP addresses.
  • Detail the process for creating and maintaining contact information in publicly accessible repositories to support global communication between network operators.

Who Should Attend

You should attend this course if you are a network administrator, network engineer, or other technical person with a working knowledge of routing and security, and you are looking for a basic steps to improve your network’s routing security.

What You Will Learn

These tutorials provide an introduction to MANRS, including the four Actions all network operators should implement to improve both the Internet’s routing security and their own network’s operational efficiency. There are six modules in total:

  • Module 1: Introduction to MANRS
  • Module 2: IRRs, RPKI, and PeeringDB
  • Module 3: Filtering: Preventing propagation of incorrect routing information
  • Module 4: Anti-Spoofing: Preventing traffic with spoofed source IP addresses
  • Module 5: Coordination: Global communication between network operators
  • Module 6: Global Validation: Facilitating validation of routing information on a global scale


This course is based on the MANRS Implementation Guide developed by the BCOP community.

We will be offering this moderated course soon, stay tuned!
