Solution Overview
Problem
Existing network security management systems in intranets face challenges in quickly identifying abnormal nodes and efficiently managing privileges, leading to potential information leakage and delays in configuring permissions, due to lack of integration and manual operation complexities.
Innovation Solution
A network security management system that includes an information collecting device, a type determining device, and an event management device to classify nodes based on login information and assign corresponding privileges, with on-line monitoring and periodically confirming devices to ensure timely detection and management of anomalies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual operation is used to verify information and manage security tasks, then flexibility in handling diverse security scenarios is improved, but operation complexity and time consumption increase significantly
Solution Approach 1:
The system enables automatic verification of information through centralized authentication mechanisms. When a user logs in, the system automatically verifies credentials against the node management list and assigns privileges without requiring manual intervention, thereby reducing operational complexity while maintaining adaptability through configurable node types and permission domains.
Solution Approach 2:
The system pre-configures node management lists with domain information, computer name information, and account information for different node types before actual security verification occurs. This preliminary setup allows the system to automatically match and verify user credentials against pre-defined node types, streamlining the verification process while maintaining flexibility for various security scenarios.
2Reliability
If manual configuration of privileges for all documents is performed, then precise control over document access is improved, but time delay increases due to enormous amount of secret documents
Solution Approach 1:
The system uses universal node types that can represent multiple specific node categories (e.g., a node type representing both domain administrators and domain users). By defining privileges at the node type level rather than for each individual document or user, the system achieves precise control over document access while dramatically reducing the time required to configure privileges for enormous amounts of secret documents.
Solution Approach 2:
The system creates template node types that can be copied and reused across multiple instances. Once a node type with specific privilege requirements is defined, it can be replicated for similar nodes without reconfiguring privileges manually, thereby maintaining precise control while reducing repetitive configuration time.
3Measurement precision
If late analysis is performed on computer statuses to find abnormal nodes, then thorough investigation of security incidents is improved, but response speed deteriorates as the problem has already occurred for a period of time
Solution Approach 1:
The system continuously monitors login events and node statuses, providing real-time feedback when anomalies are detected. The type determining device compares current login information against the node management list and immediately identifies mismatches, enabling rapid response to security incidents while maintaining accurate detection through comprehensive verification of domain information, computer names, and account credentials.
Solution Approach 2:
The system pre-establishes the node management list with all valid node types and their associated privileges before security incidents occur. This preliminary configuration enables the system to immediately compare and identify abnormal nodes during login attempts without requiring time-consuming analysis, thereby achieving both accurate detection and rapid response.
4Reliability
If comprehensive verification of node information is performed, then security reliability is improved, but system complexity and processing time increase
Solution Approach 1:
The verification system is segmented into distinct functional components: the information collecting device that gathers login credentials, the type determining device that compares credentials against the node management list, and the event management device that handles privilege assignment. This segmentation maintains comprehensive verification reliability while reducing overall system complexity by assigning specific verification tasks to dedicated modules.
Solution Approach 2:
The node management list serves as an intermediary data structure that stores pre-configured node types, domain information, computer names, and account credentials. This intermediary enables the type determining device to perform comprehensive verification without directly accessing complex privilege databases or authentication systems, thereby maintaining security reliability while simplifying the verification process.

AI summary
A network security management system which manages an object node belonging to an intranet, including: an information collecting device, a type determining device and an event management device; the information collecting device being configured to collect domain information, computer name information and account information of each object node which is transmitted when each object node performs a login operation; the type determining device being configured to perform a comparison between the node information received by the information collection device and a node management list to determine a node type belonging to each object node; the event management device being configured to decide whether the object node has an operating privilege, or to give to the object node the operating privilege corresponding to the node type of the object node based on the compared result from the type determining device.
