Null Address Routing for DDoS Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network-based computing resources are vulnerable to manipulation by command and control nodes, leading to disruptions and inefficiencies, particularly in coordinated attacks like DDOS, which affect both the targeted systems and the network service providers.
Innovation Solution
Implementing a monitoring and mitigation service that utilizes null address routing to identify and characterize command and control nodes, thereby disrupting their communication with network-based resources, using null routing addresses to terminate or block their communications and prevent further manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network-based computing resources are made available for public access, then network service productivity and resource utilization are improved, but vulnerability to manipulation and coordinated attacks increases
Solution Approach 1:
The patent introduces a monitoring and mitigation service as an intermediary between network users and computing resources. This service acts as a mediator that monitors resource usage, identifies compromised resources through behavioral analysis, and implements mitigation techniques such as null routing to block attacks while allowing legitimate traffic to continue flowing to the resources.
Solution Approach 2:
The system performs preliminary monitoring and characterization of computing resources to identify compromised status before attacks occur. By continuously monitoring resource behavior and comparing it against baseline patterns, the system detects anomalies indicating compromise in advance, enabling proactive mitigation rather than reactive response.
2Reliability
If monitoring and mitigation services are implemented to detect compromised resources, then network security is improved, but system complexity increases
Solution Approach 1:
The monitoring and mitigation service creates virtual copies or representations of computing resources to monitor their behavior without interfering with actual operations. By analyzing copies of resource data and communication patterns, the system can identify compromised resources and implement mitigation at the routing level without adding physical complexity to the underlying infrastructure.
3Object-generated harmful factors
If null routing is used to block command and control nodes, then attack disruption is improved, but routing information must be dynamically updated
Solution Approach 1:
The patent implements dynamic null routing where routing tables are automatically updated based on real-time identification of compromised resources. The system transitions from static routing configurations to dynamic routing that adapts to changing threat conditions, allowing null routes to be created, modified, or removed as resources are identified as compromised or recovered.
Data Source
AI summary
The present disclosure generally relates to systems and methods for utilization of network mitigation techniques in the form of null address routing to mitigate coordinated DDOS attacks. A monitoring and mitigation service can characterize a command and control node as compromised or otherwise manipulated for purposes of generating distributed attacks. The monitoring and mitigation service can then identify network mitigation information in the form of null routing addresses that will cause network communications associated with the identified command and control node to be terminated or otherwise not delivered to the intended network-based resources. The monitoring and mitigation service can propagate the null routing address to routing components. The network mitigation information can be associated with expiration criteria for the routing components that receive and implement the network mitigation technique.
