Network Security Module Reducing Vulnerability Window
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network security measures, such as anti-virus software and firewalls, are inadequate in protecting computing devices from unknown computer exploits and vulnerabilities, leading to a vulnerability window where systems are exposed to attacks until updates are installed, and they do not adapt to individual device needs.
Innovation Solution
A network security module that connects between computing devices and the network, implementing security patches and measures based on device-specific configuration information, providing real-time protection and minimizing the vulnerability window by dynamically controlling network access and traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anti-virus software and firewalls are used, then protection against known exploits is provided, but protection against unknown exploits and vulnerabilities is inadequate, creating a vulnerability window
Solution Approach 1:
The security module proactively receives and implements security patches from the security server before the computing device itself is updated. This preliminary action closes the vulnerability window by having protection measures in place before the device would otherwise be exposed to unknown exploits, thereby improving reliability without extending the vulnerability exposure time
Solution Approach 2:
A dedicated security module is introduced as an intermediary component between the computing device and the network. This module maintains direct communication with a security server and can receive, store, and implement security patches independently of the device's update status, providing continuous protection against both known and unknown exploits while the device transitions through its update cycle
2Reliability
If security patches are implemented through traditional update mechanisms, then protection is provided, but the device remains vulnerable until updates are installed
Solution Approach 1:
The security module performs preliminary security patch implementation by receiving patches from the security server in advance and applying them before the computing device completes its own update process. This ensures protection is active during the vulnerability window that would otherwise exist between exploit release and device update installation
Solution Approach 2:
The security module dynamically manages security patches by continuously receiving updates from the security server, storing them in memory, and implementing them as needed. This dynamic approach allows the protection level to adapt in real-time to emerging threats, maintaining reliability regardless of the device's update status or the time delay in official updates
3Adaptability or versatility
If generic security measures are applied, then general protection is provided, but adaptability to individual device needs is lacking
Solution Approach 1:
The security module implements device-specific security measures by receiving configuration information from the computing device and using it to customize security patches and protection parameters. This local quality approach ensures each device receives tailored protection based on its specific configuration, operating system, and vulnerability profile, enhancing adaptability without significantly increasing overall system complexity
Solution Approach 2:
The system employs feedback mechanisms where the security module continuously receives configuration information and status updates from the computing device, processes this information against security intelligence from the security server, and adjusts security measures accordingly. This feedback loop enables adaptive protection that responds to individual device needs while maintaining manageable complexity through automated decision-making

AI summary
A network security module for protecting computing devices connected to a communication network from security threats is presented. The network security module is interposed, either logically or physically, between the protected computer and the communication network. The network security module receives security information from a security service. The security information comprises security measures which, when enforced by the network security module, protect the computer from a security threat to the computer. The network security module implements the security measures by controlling the network activities between the protected computer and the network. The network security module also temporarily implements security patches until corresponding patches are installed onto the protected computer.
