Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network security systems are inefficient due to the lack of coordinated protection across multiple layers, requiring independent setup and programming of security devices, leading to vulnerabilities and increased complexity for network administrators.
Innovation Solution
A multilayer access control security system that automates the generation and application of access policy rules across various network layers, reducing the need for multiple rule generation mechanisms and allowing for coordinated filtering to enhance security and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate security systems are placed at multiple levels or layers within the network, then more than one level of protection is provided, but the system becomes expensive and inefficient
Solution Approach 1:
The patent combines multiple security functions (firewall, intrusion detection, intrusion prevention, proxy server) into a single integrated security appliance. This consolidation allows the system to provide multiple levels of protection while reducing the number of separate devices, thereby lowering costs and improving operational efficiency through unified management and coordinated security responses.
Solution Approach 2:
The integrated security appliance performs multiple security functions simultaneously - acting as a firewall for network traffic filtering, intrusion detection system for threat identification, intrusion prevention system for attack blocking, and proxy server for application-level proxying. This multi-functionality eliminates the need for separate dedicated devices for each security layer, reducing overall system complexity and cost.
2Reliability
If separate security systems are placed at multiple levels or layers within the network, then more than one level of protection is provided, but the setup and programming becomes complex and time-consuming
Solution Approach 1:
By merging multiple security systems into a single integrated appliance, the patent eliminates the complexity of configuring and coordinating multiple separate devices. The unified system provides consistent security policies across all layers without requiring administrators to manually synchronize settings between different security devices, significantly simplifying setup and programming.
Solution Approach 2:
The integrated security appliance includes automated features such as automatic intrusion detection response, coordinated filtering across layers, and built-in security updates. These self-service capabilities reduce the manual configuration and programming time required to maintain effective security across multiple network layers.
3Adaptability or versatility
If traffic flows through multiple protection systems independently, then each system can be optimized for its specific function, but coordination between systems is lost resulting in inefficiencies
Solution Approach 1:
The patent merges multiple security processing functions into a single coordinated system where traffic flows through integrated firewall filtering, intrusion detection, intrusion prevention, and proxy services in a unified manner. This coordination allows the system to optimize for each specific function while maintaining overall efficiency through shared resources and synchronized decision-making across all security layers.
Solution Approach 2:
The integrated security appliance implements feedback mechanisms where intrusion detection systems can trigger prevention actions, and processing results at one layer can influence decisions at subsequent layers. This coordinated feedback loop eliminates inefficiencies by ensuring all security systems work together seamlessly rather than independently, improving overall processing efficiency while maintaining functional optimization.
Data Source
AI summary
A computer-based system provides secure, configurable access to computer network resources. A human-readable language is provided for defining access policy rules. Rules in this language are converted in an automated fashion into filters applied within the various subsystems and components in a multi-layer security system. Network users are authenticated by an access control security system that obtains basic information about that user. Based on the user ID, a set of abstract policies can be retrieved. The retrieved policies are associated with the user and the groups associated with that user. Based on the retrieved rules, a set of rules for multiple layers of the network are generated and applied to those subsystems. Two or more of the subsystems may be placed in series with different types of processing occurring in each of the subsystems, reducing the workload of subsequent subsystems.
