Dynamic IP Address Switching for Cyber Attack Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network security systems are ineffective in mitigating cyber-security attacks, particularly brute force and denial-of-service attacks, as they fail to promptly and effectively change the network address of a system under attack, allowing attackers to continue probing and overwhelming the system with external requests.
Innovation Solution
Implementing a method that detects cyber attacks and changes the IP address of a system under attack by receiving newly assigned IP addresses from a Dynamic Host Configuration Protocol server, transitioning applications to the new address, and selecting from a pool of available and least recently used IP addresses, including IPv4 and IPv6, to frustrate attackers by increasing the address space they must target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system uses a fixed IP address, then network connectivity and service availability are maintained, but the system becomes vulnerable to continuous cyber attacks such as brute force and denial-of-service attacks
Solution Approach 1:
The patent implements dynamic IP address assignment where the system automatically changes its IP address in response to detected cyber attacks. The IP address management module monitors attack patterns and triggers address changes to move the system out of the attacker's target list, thereby maintaining service availability while reducing vulnerability to persistent attacks.
Solution Approach 2:
The system changes the network address parameter dynamically based on attack detection. When a cyber attack is detected, the system retrieves a new IP address from a predefined pool and updates its network configuration, effectively changing the targeting parameter to evade ongoing attacks while maintaining connectivity.
2Object-affected harmful factors
If the system changes IP address frequently to evade attacks, then vulnerability to cyber attacks is reduced, but network connectivity and service availability may be disrupted
Solution Approach 1:
The system performs preliminary actions by pre-configuring a pool of valid IP addresses before an attack occurs. When an attack is detected, the system can immediately switch to a pre-prepared address from the pool without requiring time-consuming address acquisition procedures, thus maintaining service availability while reducing vulnerability.
Solution Approach 2:
The system implements feedback mechanisms by monitoring network traffic patterns and attack indicators to determine when IP address changes are necessary. The feedback loop ensures that address changes occur only when genuinely needed for security, preventing unnecessary disruptions to service availability while still protecting against cyber attacks.
3Reliability
If the system implements IP address change mechanisms, then resilience against cyber attacks is enhanced, but system complexity and resource consumption increase
Solution Approach 1:
The system implements self-service by automatically detecting cyber attacks and triggering IP address changes without requiring external intervention. The IP address management module autonomously monitors attack patterns, selects appropriate addresses from the pre-configured pool, and updates network configurations, thereby enhancing resilience while minimizing the operational complexity burden.
4Measurement precision
If the system monitors network traffic to detect attacks, then accuracy of attack detection is improved, but processing time and computational resources increase
Solution Approach 1:
The system applies partial monitoring by focusing detection efforts on specific attack patterns and traffic characteristics most indicative of cyber threats. Rather than analyzing all network traffic comprehensively, the system monitors for key indicators of brute force attacks, denial-of-service attacks, and other common threats, achieving sufficient detection accuracy with reduced processing overhead and faster response times.

AI summary
In response to determining that a computer is undergoing a cyber attack, a newly assigned IP address is received for the computer. A currently assigned IP address of the computer is changed to the newly assigned IP address.
