Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cyber infrastructure is vulnerable due to its static nature, providing fixed targets for attackers, and traditional security measures like firewalls and intrusion detection systems are ineffective in dynamically changing networks.
Innovation Solution
The implementation of Moving Target Technology (MTT) in computer networks, which involves pseudo-randomly modifying identity parameters such as IP and MAC addresses, and dynamically changing network topologies to create an appearance of disparate networks, using mission plans and trigger events to manage these changes without physical modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security measures like firewalls and intrusion detection systems are used around fixed assets, then security protection is provided, but the network remains vulnerable due to its static nature providing fixed targets for attackers
Solution Approach 1:
The patent implements dynamic network reconfiguration by randomly changing network topologies, asset identifiers, and communication paths on demand. The system transitions from a static network structure to a dynamic one where connections and identities are continuously reshuffled, making it impossible for attackers to map vulnerable targets. This dynamic approach directly resolves the contradiction by providing adaptability while maintaining security reliability.
Solution Approach 2:
The system changes critical network parameters including topology configuration, asset identification values, and data routing paths. By randomly modifying these parameters according to mission plans, the network creates different operational states that prevent attackers from exploiting fixed vulnerabilities. This parameter transformation approach enables the network to adapt its security posture continuously.
2Reliability
If the network structure is made dynamic to confuse adversaries, then security is improved, but network complexity and difficulty of management increase
Solution Approach 1:
The system employs autonomous agents that automatically execute network reconfiguration tasks without human intervention. These agents monitor network conditions, select appropriate mission plans, and autonomously implement topology changes and identifier transformations. This self-service capability manages the inherent complexity by automating routine reconfiguration operations, allowing the network to adapt dynamically while reducing administrative burden.
Solution Approach 2:
The system incorporates feedback mechanisms where autonomous agents monitor network state and adversary presence, then adjust mission plans accordingly. This feedback loop enables the network to respond to security threats in real-time while learning from past configurations to optimize future reconfiguration strategies, effectively managing complexity through intelligent adaptation.
3Reliability
If physical modifications are made to change network architecture, then network security is enhanced, but operational continuity and speed of response are reduced
Solution Approach 1:
The patent replaces physical network reconfiguration with software-based virtual reconfiguration. Instead of physically reconnecting hardware components, the system uses software agents to virtualize network topology changes, dynamically rewriting routing tables, firewall rules, and communication protocols. This substitution enables instantaneous network reconfiguration at software level, achieving both rapid response and enhanced security without physical modification delays.

AI summary
Systems and methods for use in a Computer Network (“CN”). The methods involve performing operations by a first sub-network in accordance with a first Mission Plan (“MP”) specifying a first process for pseudo-randomly modifying at least one first identity parameter associated with at least one first computing device of CN to specify false information. Operations are also performed by a second sub-network in accordance with a second MP specifying a second process for pseudo-randomly modifying at least one second identity parameter associated with at least one second computing device of CN to specify false information. A functional topology of the first and/or second sub-networks is selectively determined based at least one MP. The functional topology specifies the manner in which nodes of the sub-networks are to be communicatively isolated from each other so as to create an appearance of two disparate and separate networks.
