FCC Proposes New Rules to Enhance BGP Security and Protect Internet Routing

Key Insights

• BGP Security in Focus: The FCC's proposed rulemaking aims to address the inherent vulnerabilities of the Border Gateway Protocol (BGP), a critical component of internet routing.
• Mandated Risk Management Plans: Internet service providers (ISPs) will be required to develop and regularly update confidential BGP security risk management plans, demonstrating a proactive approach to addressing potential threats.
• Transparency and Accountability: Larger ISPs will also be required to submit quarterly public statements on their BGP security efforts, enhancing transparency and accountability.
• RPKI Implementation: The FCC encourages the adoption of Resource Public Key Infrastructure (RPKI) to validate IP prefixes and prevent route leaks and BGP hijacking, although its limitations are acknowledged.
• Targeted Requirements: The proposed rules primarily focus on the nine largest broadband providers, while smaller ISPs would only need to provide information upon request.

Personalized Insights

• Increased Scrutiny on ISPs: The proposed rules signify a shift towards greater regulatory oversight of BGP security practices, which could lead to improved security standards across the industry.
• Proactive Risk Assessment: ISPs should start proactively assessing their BGP security posture and developing risk management plans in anticipation of the final rules.
• Collaboration is Key: The FCC's actions align with broader government efforts to enhance internet routing security, indicating a potential for collaboration between the public and private sectors to address this critical issue.
• RPKI Implementation Challenges: While RPKI is a valuable tool, its limitations must be acknowledged. ISPs should consider deploying additional security measures alongside RPKI to ensure robust BGP security.

Observations and Recommendations

• Public Comment Period: Organizations and individuals have the opportunity to provide feedback on the proposed rulemaking during the public comment period. This is a chance to voice concerns, offer suggestions for improvement, and contribute to shaping the final regulations.
• Security Awareness for Smaller ISPs: While smaller ISPs may not be subject to the same reporting requirements, they should still be aware of the BGP security risks and take steps to mitigate them. The FCC's actions may raise awareness and encourage better security practices across the industry.
• Potential for Global Adoption: The FCC's initiatives could inspire other countries and regulatory bodies to adopt similar measures, potentially leading to a global improvement in BGP security standards.

Conclusion

The FCC's proposed rulemaking is a significant step towards strengthening the security of internet routing by addressing the vulnerabilities of BGP. While the effectiveness of these measures remains to be seen, the focus on proactive risk management, transparency, and the adoption of RPKI demonstrates a commitment to protecting the integrity and reliability of the internet infrastructure.
