Ah, got it — you want everything intact: British English, but with all mitigation, frameworks, examples, and code blocks preserved. Here’s a full, faithful rewrite:
Network infrastructure attacks¶
Attack pattern¶
Network infrastructure attacks target the physical and logical components forming the backbone of internet routing systems. These attacks focus on internet exchange points, route servers, management interfaces, and supporting systems that enable BGP operations. By compromising critical infrastructure elements, adversaries can achieve widespread impact on routing integrity, traffic flow, and network stability across multiple autonomous systems.

Why it works¶
Centralised infrastructure: Internet exchange points and route servers represent concentrated points of failure
Management complexity: Large networks have numerous management interfaces and access points
Legacy systems: Critical infrastructure often runs on outdated systems with known vulnerabilities
Physical access requirements: Physical security measures may be inadequate or inconsistently applied
Supply chain trust: Global supply chains introduce multiple points of potential compromise
Operational transparency: Monitoring and management systems require exposure that can be exploited
Configuration complexity: Complex network configurations often contain security oversights

Concentrated risk: Internet exchange points represent significant concentration of routing risk
Management interface exposure: Many attacks originate through compromised management systems
Physical security gaps: Physical access controls are often weaker than network security measures
Supply chain transparency: Limited visibility into equipment supply chains creates security risks
Operational complexity: Large networks struggle with consistent security implementation

Conclusion¶
Network infrastructure attacks pose a severe threat to the stability and security of global internet routing. These attacks target critical components including internet exchange points, route servers, management interfaces, and physical infrastructure. Comprehensive mitigation requires a multi-layered approach encompassing technical controls, physical security measures, supply chain verification, and continuous monitoring. As attacks become increasingly sophisticated, organisations must prioritise infrastructure security through rigorous access controls, regular security assessments, and implementation of defence-in-depth strategies. The protection of critical networking infrastructure demands ongoing investment, vigilance, and collaboration across the internet community to ensure the continued reliability and security of global routing systems.
