Automated DDoS Routing via BGP Configuration Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing network routing in distributed networks, such as the Internet, are inefficient and lack scalability, particularly during DDoS attacks, and do not provide adequate context or control, often relying on manual interventions by unqualified administrators and lacking historical data for route management.
Innovation Solution
A graphical user interface (GUI) interacts with a Web server to update a configuration file, which is converted into router management commands by a network management device (BGP speaker) to control border routers, enabling automated and timely routing changes, logging, and centralizing network control to prevent unqualified access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual routing changes are made by network administrators, then routing updates can be implemented, but the process lacks efficiency and scalability during DDoS attacks
Solution Approach 1:
The system enables automated routing updates through a self-service mechanism where the network management system automatically detects DDoS attacks and implements routing changes without requiring manual administrator intervention. The system monitors network traffic, identifies attack patterns, and autonomously updates BGP routing tables to divert malicious traffic, thereby improving response efficiency and eliminating delays associated with manual operations.
2Ease of operation
If junior network administrators are given access to make network changes, then routing updates can be performed, but network security is compromised due to lack of proper certifications
Solution Approach 1:
The system introduces an intermediary authentication layer between administrators and network control functions. The gateway server acts as a mediator that verifies administrator credentials and certifications before allowing access to routing update capabilities. This intermediary mechanism enables junior administrators to perform necessary tasks while maintaining network security through automated credential verification and access control policies.
3Ease of manufacture
If manual routing management is used, then network changes can be made, but historical data for route management is not captured
Solution Approach 1:
The system implements comprehensive feedback mechanisms that automatically capture, log, and store all routing changes and network events. The gateway server maintains detailed logs of routing updates, attack patterns, and system responses, creating a historical database that provides valuable information for analyzing route management effectiveness, improving future responses, and maintaining audit trails without adding complexity to the routing management process.
Data Source
AI summary
Embodiments are provided for managing routes of data traffic within a network. The management may be performed via a graphical user interface that interacts with a Web server to update a configuration file. The configuration file can be converted to router management commands by a network management device (e.g., a BGP speaker). The commands can then be sent to border routers for controlling network traffic. Embodiments are also provided for capturing and logging routing updates made in a network.
