Remote Connection Security via Dynamic Port Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote access technologies, such as RDP, face critical security issues including man-in-the-middle attacks, information leakage, and unauthorized access through brute force attacks, particularly in remote working scenarios where sensitive company information is at risk.
Innovation Solution
A remote connection enabling system that employs a management computer with a protection application and service software to manage and secure remote connections by verifying user identity, using temporary port openings, recognition codes, and restricting access based on predefined rules, ensuring only authorized computers can connect and limiting activities during sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RDP allows remote connection from any computer, then accessibility and ease of operation are improved, but security against unauthorized access and information leakage deteriorates
Solution Approach 1:
A protection application is introduced as an intermediary component between the RDP service and incoming connection requests. This protection application monitors and controls access to the RDP port, acting as a security gatekeeper that verifies connection requests before allowing them to reach the RDP service, thereby maintaining both accessibility and security
Solution Approach 2:
The system performs preliminary verification of connection requests by the protection application before the actual RDP connection is established. The protection application checks whether incoming connections are authorized based on predefined security rules, and only allows legitimate connections to proceed, preventing unauthorized access before it can compromise the system
2Ease of operation
If RDP port is continuously open for access, then ease of operation is improved, but vulnerability to brute force attacks and unauthorized access increases
Solution Approach 1:
The RDP port accessibility is made dynamic rather than static. The protection application continuously monitors incoming connection requests and dynamically adjusts the port's accessibility state - allowing connections from authorized sources while blocking or terminating connections from unauthorized sources, thereby adapting to changing security conditions in real-time
Solution Approach 2:
The protection application implements a feedback mechanism that monitors connection patterns and security events. When suspicious activity or brute force attack attempts are detected, the system responds by blocking the attacking IP addresses and adjusting security parameters, creating a closed-loop security system that learns from and responds to threats
3Productivity
If temporary user is granted full access to remote computer, then productivity is improved, but risk of information leakage and malicious activities increases
Solution Approach 1:
Different quality levels of access are assigned to different users or user groups. The protection application enforces access control policies that grant appropriate permissions based on user roles - temporary users receive limited access to specific resources or functions, while authorized users receive full access, thereby enabling productivity while minimizing security risks through differentiated access rights
