The White House Office of the National Cyber Director (ONCD) has released a comprehensive blueprint aimed at strengthening internet routing security and addressing long-standing vulnerabilities associated with the Border Gateway Protocol (BGP). The initiative, announced on Tuesday, September 3, is a significant step towards creating a more secure internet infrastructure, ensuring national security and economic prosperity.
The Challenge of BGP Vulnerabilities
BGP, a protocol that has been fundamental to the internet since 1989, enables different Autonomous Systems (AS) to communicate and exchange routing information. Each AS, typically managed by a single organization with a unique AS number, uses BGP to announce the IP addresses it can reach and to determine the best path for packet routing to other ASes. This protocol, effectively, forms the backbone of the internet.
However, BGP was not designed with modern cybersecurity threats in mind, leading to frequent accidents such as route hijacking, route leakage, and a lack of authentication. Notable incidents include the 2008 blockade of YouTube by the Pakistani government, where an attempt to block YouTube using BGP routing accidentally propagated globally, causing most YouTube traffic to be incorrectly rerouted to Pakistan. More recently, service disruptions at Meta have been traced back to BGP vulnerabilities.
The Solution: RPKI, RSA, ROV, and ROA
ONCD believes that the best approach to addressing BGP vulnerabilities involves the implementation of several key technologies and agreements: Resource Public Key Infrastructure (RPKI), Registration Service Agreements (RSA), Route Origin Validation (ROV), and Route Origin Authorizations (ROA).
- RSA serves as the legal foundation of the entire system, determining who has the authority to use specific network resources and authorizing their participation in RPKI.
- RPKI is a security framework that uses public key cryptography to validate the ownership of IP addresses and AS numbers.
- ROA is the outcome of RPKI, specifying which AS can announce specific IP prefixes.
- ROV uses RPKI and ROA data to validate the authenticity of BGP routing announcements.
Federal Government’s Role and Goals
To facilitate the adoption of these technologies, ONCD has developed a federal RSA template appendix, encouraging federal agencies to use it to promote RPKI adoption. The National Oceanic and Atmospheric Administration (NOAA) has also created a federal RPKI manual to support RSA execution and the establishment of ROAs on federal networks.
The goal is to have RSA cover more than 60% of the IP space published by federal networks by the end of this year, paving the way for the creation of ROAs. This initiative is part of a broader effort by the federal government to lead by example in enhancing cybersecurity.
Ensuring National Security and Economic Prosperity
Harry Coker, Jr., the National Cyber Director, emphasized the importance of cybersecurity, stating that the federal government must take the lead in accelerating the adoption of BGP security measures. Collaboration with the private sector and the development of this blueprint are crucial steps in mitigating long-standing vulnerabilities and creating a safer internet.
The ONCD’s blueprint is a significant move towards securing the internet’s infrastructure, ensuring that the United States can maintain its national security and economic prosperity in an increasingly digital world. By addressing BGP vulnerabilities, the initiative aims to reduce the risk of cyber attacks and improve the overall resilience of the internet.
Conclusion
The release of the blueprint by the White House ONCD underscores the critical need to enhance internet routing security. By focusing on RPKI, RSA, ROV, and ROA, the initiative seeks to create a more secure and reliable internet for everyone. As the federal government leads the way, it is hoped that the private sector will follow suit, creating a safer digital environment for all.
