Dynamic Address State Lifecycle Management for Network Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network security systems are inadequate in detecting and preventing attacks, as they rely on outdated protocols with vulnerabilities, leading to false positives, false negatives, and inefficient response times, and often fail to detect new or undocumented threats.
Innovation Solution
A system and method for managing logical and physical address state lifecycles by assigning and changing address states based on communication interactions, using a computational device with tables and rules to identify and mitigate threats by altering ARP tables and controlling communication flows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional network security protocols are used, then network compatibility is maintained, but security detection accuracy deteriorates due to false positives and false negatives
Solution Approach 1:
The patent changes the state parameters of network addresses from static to dynamic, introducing multiple states (unknown, used, unfulfilled, omitted, virtual) that evolve based on communication interactions. This allows the system to adapt security detection to the actual lifecycle stage of each address, improving detection accuracy without compromising compatibility
Solution Approach 2:
The system implements dynamic address state management where addresses transition through different states based on real-time communication patterns. This dynamic approach enables the security system to respond adaptively to changing network conditions, reducing false positives while maintaining detection of actual threats
2Reliability
If comprehensive address monitoring is implemented, then threat detection capability is improved, but system complexity increases
Solution Approach 1:
The patent segments the address monitoring system into distinct state categories (unknown, used, unfulfilled, omitted, virtual), each with specific handling rules. This segmentation simplifies the overall system by breaking down complex monitoring into manageable state transitions, reducing system complexity while maintaining comprehensive detection capability
Solution Approach 2:
The address state table serves as an intermediary structure that mediates between raw communication data and security detection logic. By introducing this intermediate layer, the system manages complexity by providing a standardized interface for tracking address lifecycles without requiring complex analysis at each detection point
3Loss of time
If real-time address state tracking is implemented, then response time to threats is improved, but computational overhead increases
Solution Approach 1:
The system performs preliminary actions by pre-defining address states and their transition rules before actual security events occur. This allows the system to quickly evaluate address states during security incidents without performing complex real-time analysis, reducing both response time and computational overhead
Solution Approach 2:
The address state tracking system serves itself by automatically transitioning addresses between states based on predefined communication patterns. This self-service mechanism eliminates the need for continuous computational analysis, reducing overhead while maintaining real-time tracking capability

AI summary
A system and method for managing logical and physical address state lifecycles. A state of unknown can be assigned to an address when the state has not been assigned. The state of the address is changed when communication is targeted to the address. The state can be changed to unfulfilled when the communication includes an address resolution protocol request sent to a device having the address when a time limit for a response to the address resolution protocol request has not expired. The state can be changed to virtual when the communication is received at the address when the state of the address is unfulfilled, and a time limit for responding to the communication expires before a response is sent. The state can be changed to unknown when the state of the address is not unknown, and the address does not participate in the communication within a time limit.
