Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current device classification methodologies in network security are inadequate as they rely on static attributes, which are insufficient for providing accurate and comprehensive device classification, especially in the context of rapidly increasing network-connected devices like IoT devices.
Innovation Solution
The implementation of behavior-based profiling systems that analyze entity behaviors over time, correlate these behaviors, and use unique behavioral patterns to generate profiles for accurate classification of devices, even in the absence of complete static attribute information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If static attribute-based classification is used, then the classification process is simple and fast, but the classification accuracy is insufficient especially for IoT devices with incomplete attributes
Solution Approach 1:
The patent transitions from static attribute-based classification to dynamic behavior-based classification. The system continuously monitors and analyzes device behaviors over time, adapting classification profiles based on observed patterns. This dynamic approach enables accurate classification of IoT devices even when static attributes are incomplete or unavailable, directly resolving the contradiction between classification accuracy and system complexity.
Solution Approach 2:
The patent changes the classification parameters from static device attributes (MAC address, device type) to dynamic behavioral parameters (communication patterns, data transmission timing, protocol usage). By monitoring multiple behavioral parameters over time and analyzing their sequences, the system achieves higher classification accuracy without requiring complete static attribute information.
2Measurement precision
If behavior-based profiling is implemented, then classification accuracy improves, but the monitoring and analysis complexity increases
Solution Approach 1:
The patent segments behavior analysis into distinct sequential steps: capturing communication events, extracting behavioral parameters, forming behavior sequences, and matching against profiles. This segmentation reduces the complexity of behavior detection by breaking down the continuous monitoring task into discrete, manageable components that can be processed systematically.
Solution Approach 2:
The patent performs preliminary actions by pre-defining behavior profiles and parameter extraction rules before actual device classification. The system prepares classification templates and behavioral patterns in advance, which simplifies real-time analysis by providing a structured framework for evaluating device behaviors against known patterns.
3Adaptability or versatility
If comprehensive behavior monitoring is performed, then unknown devices can be identified, but the data processing load increases
Solution Approach 1:
The patent extracts only the essential behavioral parameters needed for classification from the full network traffic data. Instead of analyzing all communication data, the system selectively captures key parameters such as timing patterns, protocol types, and sequence structures. This extraction approach enables identification of unknown devices while minimizing the data processing load and preserving network throughput.

AI summary
Systems, methods, and related technologies for profiling an entity and classifying an entity based on a profile are described. In certain aspects, data associated with communications of a first entity on a network are accessed, behaviors are determined based on the data associated with the communications of the first entity, and sequences of the behaviors of the first entity are determined. A profile of the first entity is determined based on the sequences of the behaviors, the profile including a classification of the first entity, a state machine of the profile of the first entity is determined, the state machine being associated with the classification against which the behaviors can be matched, a second entity is detected coming onto the network, and responsive to detecting the second entity coming onto the network, the second entity is classified based on the state machine of the profile of the first entity.
