Inter-Cloud Attack Prevention via Coordinated Notification Protocol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cloud management services lack a standardized protocol for communicating and coordinating with each other to detect and mitigate distributed denial-of-service (DDoS) and other cyber attacks that cross network boundaries, making it difficult to effectively manage and respond to inter-cloud attacks.
Innovation Solution
A shared intra-cloud communication protocol is introduced that allows cloud management services to monitor traffic, identify potential attacks, and request restrictions on egress traffic from other services using JSON files and REST-based services, enabling coordinated responses to cyber threats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cloud management services use different attack detection and mitigation protocols, then each service can operate independently with its own security policies, but coordination between services during inter-cloud attacks becomes difficult and ineffective
Solution Approach 1:
The patent implements a universal notification protocol that enables cloud management services to communicate attack information across different security domains. The protocol defines standardized message formats including attack detection notifications, blocking requests, and confirmation responses that can be exchanged between any cloud management services regardless of their native security protocols, thereby achieving both reliability in attack mitigation and adaptability across diverse systems
2Reliability
If cloud management services implement comprehensive attack detection and coordination mechanisms, then inter-cloud attack response capability improves, but system complexity and implementation difficulty increase
Solution Approach 1:
The patent segments the attack response process into distinct, manageable protocol messages: attack detection notifications containing attack parameters, blocking requests with specific blocking parameters, and confirmation responses. This segmentation allows each message type to have a focused, simple structure while the overall system achieves comprehensive attack response capability through the coordination of these discrete message exchanges
3Reliability
If cloud management services exchange detailed attack information across network boundaries, then coordinated attack mitigation improves, but information security and trust management become more challenging
Solution Approach 1:
The patent implements a feedback mechanism where the receiving cloud management service sends confirmation responses back to the notifying service, indicating whether blocking actions were successfully implemented. This feedback loop enables coordinated attack mitigation by verifying that mitigation actions are effective while maintaining information security through authenticated, bidirectional communication that establishes trust between services

AI summary
Devices, systems, and methods are provided for detecting and preventing inter-cloud attacks. A method may include determining, by a first cloud management service, a cyber attack on a second cloud management service using the first cloud management service, and determining two or more source Internet protocol (IP) addresses associated with the cyber attack. The method may include determining a response to the cyber attack, the response associated with controlling egress traffic from the first cloud management service, the egress traffic associated with the two or more source IP addresses. The method may include sending a notification to the second cloud management service, the notification including an indication of the response.
