Securing BGP Routing in Latin America
Network operators across Latin America and the Caribbean unite to bolster BGP security amid rising threats to global connectivity.
The internet’s backbone relies on the Border Gateway Protocol (BGP) to direct data across global networks. However, BGP’s foundational design lacks inherent safeguards, leaving it exposed to manipulations that can disrupt services, compromise privacy, and undermine trust. In Latin America and the Caribbean, where digital economies are expanding rapidly, network operators are increasingly aware of these risks. Recent collaborative efforts signal a turning point, with commitments to advanced security measures that promise a more resilient routing ecosystem.
Understanding BGP Vulnerabilities
BGP operates by enabling autonomous systems (ASes)—networks managed by ISPs, governments, or enterprises—to exchange routing information. Without validation mechanisms, malicious actors can announce false routes, intercepting traffic destined for legitimate destinations. This vulnerability manifests in two primary forms: prefix hijacks and route leaks.
Prefix hijacks occur when an AS falsely claims authority over IP address blocks it does not own, diverting traffic to unauthorized servers. Route leaks happen when internal routing policies are inadvertently or maliciously exposed globally, flooding networks with suboptimal paths and causing outages. Both disrupt connectivity, but their impacts extend to economic losses, data breaches, and threats to critical infrastructure.
- Hijacks: Intentional redirection for surveillance or denial-of-service.
- Leaks: Accidental propagation due to misconfigurations.
- Consequences: Blackouts for millions, as seen in major incidents affecting financial systems and e-commerce.
In the Latin American context, these issues are amplified by the region’s growing internet penetration, now exceeding 70% in many countries, per regional registries like LACNIC.
Regional Incident Landscape
Data from monitoring tools reveals a troubling pattern. Between 2017 and 2019, the region recorded thousands of BGP incidents, with Brazil prominently featured due to its vast AS footprint. Analysis shows over 75% of 2017 events involved Brazilian networks, highlighting the need for targeted interventions.
| Year | Total Incidents LAC | Brazil Involvement (%) | Common Types |
|---|---|---|---|
| 2017 | 4,950 | 76.1% | Hijacks (45%), Leaks (55%) |
| 2018 | ~2,400 | High | Leaks dominant |
| 2019 (partial) | Increasing | Top 5 | Mixed |
These figures underscore the urgency. Incidents not only affect local users but propagate globally, impacting international traffic flows.
Key Initiatives Driving Change
Operators are responding through structured programs. The FORT Project, a collaboration between LACNIC and NIC.MX, spearheads RPKI deployment—a cryptographic system using public key infrastructure (PKI) to certify route origins. RPKI issues Route Origin Authorizations (ROAs), digitally signed proofs of IP ownership, enabling filters to discard invalid announcements.
Complementing this is MANRS (Mutually Agreed Norms for Routing Security) from the Internet Society. MANRS outlines actionable steps:
- Filter announcements from non-origins.
- Validate global routes against RPKI.
- Protect the routing plane from tampering.
- Report incidents transparently.
At LACNIC 31 in May 2019, operators publicly pledged adherence, marking a collective push toward implementation.
Progress in RPKI Adoption
RPKI uptake has accelerated. By late 2019, several ASes in the region validated roots, with Brazil, Mexico, and Argentina leading. Tools like FORT’s diagnostic reports provide AS-specific recommendations, simplifying deployment.
Benefits include:
- Automated Validation: ROA checks at peering edges block 90%+ of known hijacks.
- Scalability: Supports growing IPv6 deployments.
- Interoperability: Aligns with global standards from standards bodies like IETF.
Challenges persist, such as key management complexities and legacy system integrations, but training workshops are bridging gaps.
Case Studies of Operator Commitments
Prominent players have stepped up. Liberty Networks, spanning 30+ countries with extensive subsea cables, integrates RPKI into its backbone. Other adopters include national backbones in Colombia and Peru, reducing incident rates post-implementation.
One operator reported a 40% drop in leaked routes after MANRS filters, demonstrating tangible gains. These successes inspire peers, fostering a domino effect across the region.
Future Roadmap for Resilience
To sustain momentum, stakeholders advocate for:
- Policy incentives from regulators for RPKI/MANRS compliance.
- Expanded monitoring via shared platforms like those from LACNIC.
- IPv6-specific security enhancements.
- Cross-border coordination to mitigate propagation.
By 2026, projections suggest 50%+ ROA coverage in LAC, potentially halving incidents if trends hold.
Broader Implications for Digital Economies
Secure routing underpins e-commerce, remote work, and smart cities. In a region contributing 8% to global GDP, disruptions cost billions annually. Strengthened BGP protects investments in 5G rollouts and fiber expansions.
FAQs
What is BGP and why is it vulnerable?
BGP is the protocol routing internet traffic between networks. It’s vulnerable due to trust-based announcements without origin validation.
How does RPKI fix BGP issues?
RPKI uses digital certificates (ROAs) to prove route ownership, allowing networks to filter invalid paths automatically.
Which countries lead RPKI in Latin America?
Brazil, Mexico, Argentina, and Colombia show highest adoption rates per FORT diagnostics.
What is MANRS?
A set of voluntary norms by Internet Society to improve routing hygiene through filtering, validation, and reporting.
Are there costs to implementing these?
Initial setup requires effort, but tools and free services from registries minimize barriers; benefits outweigh long-term.
