Network Node Address Hopping for Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network protection technologies are inadequate in preventing service attacks that rely on discovering and exploiting network addresses, as they often limit network capabilities and are ineffective against advanced mapping and fingerprinting techniques.
Innovation Solution
Implementing a network address hopping method where a network node changes its address upon recognizing a trigger, using a 'hopping' scheme to establish logical channels and render nodes unreachable to most current exploits, optionally incorporating a honeypot for additional protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network protection technologies such as firewalls and virtual private networks are deployed to block discovery and exploitation, then network security is improved, but network capabilities are limited
Solution Approach 1:
The network node dynamically changes its network address over time through address hopping, transitioning from a static address to a dynamic, time-varying address. This allows the node to maintain security while preserving network capabilities, as the address changes are controlled and predictable for legitimate communications
Solution Approach 2:
The invention changes the network address parameter of the node periodically or based on triggers, transforming the address from a constant value to a time-dependent variable. This parameter change enables the node to evade discovery-based attacks while maintaining functional network access through coordinated address updates
2Reliability
If existing tools are used to limit reachability and block malicious activity, then protection against exploitation is improved, but effectiveness against advanced mapping and fingerprinting techniques deteriorates
Solution Approach 1:
By implementing dynamic address hopping, the node becomes unpredictable to mapping and fingerprinting tools that rely on scanning and identifying static addresses. The continuous address changes render traditional discovery techniques ineffective while maintaining protection against exploitation
Solution Approach 2:
The address hopping mechanism operates periodically or based on time intervals, creating a rhythmic pattern of address changes that disrupts mapping and fingerprinting attempts. This periodic action ensures that attackers cannot establish persistent connections or accurately map the node's presence in the network
