NIST requests comments on guidance about Resilient Interdomain Traffic Exchange

Published: Tuesday, 22 October 2019 07:24

NIST has released a second public draft of NIST Special Publication (SP) 800-189, Resilient Interdomain Traffic Exchange: BGP Security and DDoS Mitigation. This document provides technical guidance and recommendations for technologies that improve the security and robustness of interdomain traffic exchange. Technologies recommended in this document for securing the interdomain routing control traffic include Resource Public Key Infrastructure (RPKI), BGP origin validation (BGP-OV), and prefix filtering. Additionally, technologies recommended for mitigating DoS and DDoS attacks include prevention of IP address spoofing using source address validation with access control lists (ACLs) and unicast Reverse Path Forwarding (uRPF). Other technologies such as remotely triggered black hole (RTBH) filtering, flow specification (Flowspec), and response rate limiting (RRL) are also recommended as part of the overall security mechanisms.

The public comment period ends on November 15th, 2019.
