Secure Container Lockout for Critical Infrastructure Network Breaches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems for critical infrastructure, such as wind turbines and electric power grids, fail to effectively prevent unauthorized access and subsequent network infiltration, as they lack robust mechanisms to immediately disable outgoing communications upon unauthorized portal breaches.
Innovation Solution
A secure container system equipped with a security checkpoint and a logical lock module that switches to a breach mode upon unauthorized access, triggering the network switch to disable outgoing communications, thereby preventing unauthorized network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secure container with access control is used to protect critical infrastructure, then security against unauthorized access is improved, but the system complexity increases
Solution Approach 1:
The patent combines multiple security functions (access control monitoring, breach detection, and network communication disabling) into an integrated system where the logical lock module coordinates between the physical lock and network switch, reducing overall system complexity while maintaining high security
2Reliability
If a logical lock module is added to monitor access portal state and trigger breach mode, then security response capability is improved, but device complexity increases
Solution Approach 1:
The logical lock module serves multiple functions: it monitors the access portal state, determines breach conditions, triggers breach mode, and coordinates with both the physical lock and network switch, thereby improving security response capability without requiring separate dedicated components for each function
3Reliability
If the network switch disables outgoing communications upon breach detection, then prevention of network infiltration is improved, but loss of legitimate communications increases
Solution Approach 1:
The system preemptively disables outgoing network communications upon detecting a breach condition, before unauthorized infiltration can occur. This preliminary protective action blocks potential threats while the breach is being addressed, accepting temporary communication loss as necessary for security
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively impedes unauthorized network infiltration by immediately disabling outgoing communications upon unauthorized access, thereby protecting critical infrastructure from potential threats.
Implementation Method 1
A magnetic reed switch (or simply a reed switch) is an electrical switch operated by an applied magnetic field
Implementation Method 2
When the electromagnet is energized, a current passing through the electromagnet creates a magnetic flux that causes the armature plate to attract to the electromagnet, creating a locking action

AI summary
A system for preventing unauthorized access to a network can include a secure container having an access portal for controlling access to contents of the secure container and a security checkpoint configured to determine a state of the access portal and to receive an authorization code for opening the access portal. The security checkpoint can also include a logical lock module that switches to a breach mode of operation in response to a signal from the security checkpoint indicating that the access portal has been opened without receipt of the authorization code within a predetermined amount of time. The system can also include a network switch disposed within the secure container. The network switch is configured to communicate on a network and disable outgoing network communications to the network in response to a breach signal indicating that the logical lock module has switched to the breach mode.
