What are some case studies on routing security?

What are some case studies on routing security?

Routing security involves protecting the integrity and availability of routing protocols. Here are a few notable case studies: 1. The 2018 Facebook BGP Incident, where misconfigured routers led to a significant outage. 2. The 2019 Google Cloud BGP Leak, which affected multiple services. 3. The 2020 AWS Route 53 Incident, where DNS misconfigurations caused service disruptions.

Can you explain the impact of the Facebook BGP incident?

Certainly! The Facebook BGP incident in 2018 occurred when a misconfiguration in BGP routing caused a significant portion of the internet to route traffic through Facebook's network. This led to service disruptions for many users and highlighted the vulnerabilities in BGP, emphasizing the need for better routing security practices.

What measures can be taken to improve routing security?

To improve routing security, organizations can implement several measures: 1. Use prefix filtering to prevent unauthorized route announcements. 2. Implement RPKI (Resource Public Key Infrastructure) to validate route origins. 3. Regularly audit and monitor routing configurations to detect anomalies.

Are there any tools available for monitoring routing security?

Yes, there are several tools available for monitoring routing security, including: 1. BGPmon - for monitoring BGP announcements. 2. RIPE NCC's RIS - for analyzing routing information. 3. Cisco's Prime Infrastructure - for comprehensive network management and monitoring.
