Net Access Controller for Dynamic Network Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data communication systems are vulnerable to intrusions and unauthorized access, particularly due to continuous network connectivity, which makes them susceptible to hacking, espionage, and misuse, especially for small entities and home users who cannot afford or maintain complex security measures like firewalls.
Innovation Solution
A net access controller that dynamically manages network connectivity based on user activity, using a switch to interrupt the physical connection between the computer and the network, thereby reducing the time a device is connected and minimizing the risk of intrusion by only allowing access when user activity is detected, and providing mechanisms to disconnect secondary input/output devices and alert users to potential threats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If continuous network connection is maintained for fast access and communication, then communication efficiency is improved, but vulnerability to intrusions and unauthorized access increases
Solution Approach 1:
The system implements periodic disconnection of network access based on user activity detection. When no user activity is detected for a predetermined time period, the network access is automatically disconnected. This periodic action maintains security by limiting continuous exposure to network threats while allowing efficient communication during active usage periods.
2Reliability
If firewalls are installed for comprehensive security protection, then security level is improved, but system complexity and maintenance cost increase
Solution Approach 1:
The invention extracts the essential security function from complex firewall systems and implements it through a simpler mechanism: automatic disconnection of network access based on user activity detection. This removes the need for complex firewall software and configuration while maintaining effective security protection by physically disconnecting the network connection when not in use.
3Ease of operation
If network access is continuously available for user convenience, then ease of operation is improved, but risk of unauthorized use increases
Solution Approach 1:
The system employs feedback mechanisms through activity detection means that continuously monitor user activity. When activity ceases for a predetermined period, the system automatically disconnects network access. This feedback loop maintains user convenience during active use while automatically preventing unauthorized access during idle periods, creating a dynamic security response.

AI summary
The present invention relates to a device and method for increasing the security for a computer or server adapted for communication with a communication network, for example the Internet. The method for automatically controlling access between the computer and the communication network arranges the access to be dependent on user activity. The user activity is determined by monitoring signal activity between the computer and at least one input/output device adapted for communication with the computer, and the user activity being defined as detection of signal activity between the computer and the input/output device. Access to the communication network is only allowed if user activity is occurring or has occurred in a predetermined time period.
