Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static IP address schemes and manual tagging processes are used for network segmentation, then network security can be maintained in traditional environments, but the system becomes inadequate for managing dynamic and unpredictable environments with IoT devices and user mobility
Solution Approach 1:
The patent implements dynamic segmentation by transitioning from static IP-based segmentation to a system that automatically adapts segmentation policies based on real-time network conditions, device types, and user mobility patterns. The system continuously monitors network traffic and dynamically adjusts segmentation rules without requiring manual reconfiguration, enabling effective management of IoT devices and mobile users while maintaining network security.
2Reliability
If granular and flexible segmentation policies are implemented, then network security is improved and risk of device compromises is reduced, but the configuration and management becomes more complex
Solution Approach 1:
The patent implements self-service segmentation by enabling the system to automatically generate, configure, and enforce segmentation policies based on predefined criteria and real-time network observations. The system autonomously performs device classification, policy generation, and enforcement point configuration without requiring manual intervention, thereby achieving granular security control while simplifying management complexity.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system continuously monitors network traffic, device behavior, and segmentation policy effectiveness. Based on this feedback, the system automatically adjusts and optimizes segmentation policies to maintain high security standards while adapting to changing network conditions, reducing the need for manual policy configuration and management.
3Adaptability or versatility
If segmentation policies are independently designed and configured, then flexibility and adaptability are improved, but the translation and enforcement across various enforcement points becomes more challenging
Solution Approach 1:
The patent implements universal segmentation enforcement by designing a unified policy translation mechanism that can enforce segmentation policies across multiple types of enforcement points (firewalls, switches, routers, cloud security services) using a common configuration framework. The system translates high-level segmentation policies into device-specific configurations automatically, enabling flexible policy design while simplifying enforcement across heterogeneous network infrastructure.
Solution Approach 2:
The patent introduces an intermediary policy translation layer that sits between the segmentation policy design interface and the various enforcement points in the network. This intermediary automatically translates and adapts segmentation policies to the specific requirements and configuration formats of different enforcement point types, thereby maintaining policy flexibility while easing the complexity of enforcement across diverse network devices.

AI summary
Systems, methods, and related technologies for segmentation management are described. The segmentation management may include visualization, configuration including translation, simulation, or a combination thereof of one or more segmentation policies. In certain aspects, a segmentation policy is accessed and a segmentation rule is determined based on the segmentation policy, wherein the segmentation rule is based on a characteristic of an entity determined without the use of an agent. An enforcement point associated with the segmentation rule may be determined, where the enforcement point is communicatively coupled to a network. The segmentation rule may be translated into a configuration associated with the enforcement point and the configuration communicated to the enforcement point.
