Network Security Device Selective Feature Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security systems consume significant system resources by deploying all security features for every URL accessed, regardless of whether the destination is trusted or malicious, leading to performance issues.
Innovation Solution
A network security device selectively enables or disables security features based on the trust level of the destination URL, intercepting network traffic and using a trusted network parameters database to determine whether to apply security features, thereby optimizing resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all security features are deployed for every URL accessed, then security protection is improved, but system resource consumption increases
Solution Approach 1:
The patent applies different security feature sets to different URL categories. Trusted URLs receive minimal or no security features, while untrusted URLs receive full security inspection. This local differentiation resolves the contradiction by optimizing resource usage for trusted sites while maintaining security for untrusted sites.
Solution Approach 2:
The system dynamically adjusts the application of security features based on real-time URL trust assessment. The network security device evaluates each URL and adaptively enables or disables security features accordingly, rather than using a static all-or-nothing approach. This dynamic adjustment resolves the contradiction between security and resource consumption.
2Reliability
If all security features are deployed for every URL accessed, then security protection is improved, but system performance deteriorates
Solution Approach 1:
By applying security features locally based on URL trust status, the system avoids unnecessary processing for trusted URLs, thereby improving overall system performance while maintaining security where needed.
Solution Approach 2:
The system applies partial security action (reduced or no security features) for trusted URLs and full security action for untrusted URLs. This partial application resolves the contradiction by eliminating excessive security processing for trusted sites while maintaining adequate protection for untrusted sites.
3Use of energy by moving object
If security features are selectively disabled for trusted websites, then system resource consumption is reduced, but security coverage is compromised
Solution Approach 1:
The system performs preliminary trust assessment of URLs before determining security feature application. By pre-evaluating URL trust status using reputation databases and historical data, the system can confidently disable security features for trusted URLs without compromising security coverage, as the trust assessment is performed in advance.
Solution Approach 2:
The system uses feedback from URL reputation databases, threat intelligence feeds, and historical security data to dynamically determine security feature application. This feedback mechanism ensures that security coverage is maintained for untrusted URLs while allowing resource optimization for trusted URLs.
Data Source
AI summary
Systems and methods for optimizing system resources by selectively enabling various scanning functions of a network security device are provided. According to one embodiment, information specifying a set of reputable websites deemed to be trustworthy by one or more web filtering services is received by a network security device protecting a private network. One or more directives are received by the network security device from a network administrator via a GUI of the network security device identifying one or more security features that are to be disabled for the set of reputable websites. Network traffic is intercepted by the network security device from an external network. When it is determined by the network security device that the external network is among the set of reputable websites, the network security device foregoes application of the one or more identified security features to the network traffic.
