Dynamic Security Perimeter Defense via Distributed Module Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network security systems rely on static security perimeters, which can be computationally expensive and lack redundancy, leading to potential vulnerabilities if individual components fail, as the burden of security falls on individual computers rather than distributed network elements.
Innovation Solution
Implementing a method to dynamically configure security mechanisms by activating and deactivating security function modules across network elements and systems based on their operational status, ensuring that security functions are allocated efficiently and effectively, providing multiple layers of defense and redundancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a router inspects data packets to provide security, then security is improved, but the computational load and expense of the router increases significantly
Solution Approach 1:
The patent divides the security inspection function into separate security function modules that can be distributed across multiple network elements and systems. Instead of concentrating all security inspection in the router, the system segments security functions into independent modules that can be activated or deactivated based on operational status, thereby reducing the router's computational burden while maintaining security through distributed inspection capabilities.
2Reliability
If security functions are distributed across multiple network elements, then redundancy and reliability are improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic activation and deactivation of security function modules based on the operational status of network elements and systems. This dynamic approach allows the system to automatically adjust which security modules are active, providing redundancy when needed while simplifying operations when fewer modules are required. The dynamic configuration reduces manual intervention and simplifies system management despite the distributed architecture.
3Reliability
If static security perimeters are deployed concentrically, then multiple lines of defense are provided, but the computational expense increases and individual component failures create vulnerabilities
Solution Approach 1:
The patent changes the operational parameters of security function modules by dynamically adjusting their activation state based on real-time conditions. Instead of maintaining all security perimeters at full operational capacity continuously, the system modifies parameters such as module activation status and inspection intensity based on threat levels and component operational status, thereby reducing computational expense while maintaining multiple lines of defense when needed.

AI summary
Techniques for dynamically configuring security mechanisms in a network can construct security perimeters that satisfy security needs at any given time while also efficiently spreading security functions among network elements and systems. In one technique, a network element comprises security function modules. Systems toward which the network element forwards data packets also comprise security function modules. A particular security function module on the network element begins in a state of deactivation. The network element determines whether a corresponding security function module on one of the systems is functioning in a satisfactory manner. If not, then the network element activates the particular security function module. While activated, the particular security function module may perform at least some of the security function operations that the corresponding security function module would have performed if the corresponding security function module was satisfactory.
