Gateway Audit Log for Data Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote connection methods between secured and unsecured networks are vulnerable to advanced attacks, such as 'man in the middle' attacks and data leakage, due to the limitations of traditional security paradigms that rely on firewalls and intrusion prevention systems, which struggle to detect unknown or encrypted malicious activities.
Innovation Solution
A system and method that includes a server with a protection module to validate and reconstruct user commands, create a security image, and a secured transmission module to ensure secure image transmission, using CAPTCHA challenges and one-way video transmission to prevent data leakage and ensure secure data exchange between networks with different security classifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional firewalls and intrusion prevention systems are used to protect network communications, then basic security against known attacks is provided, but sophisticated attacks such as 0-Day attacks and encrypted malicious activities pass undetected
Solution Approach 1:
The patent introduces a gateway server as an intermediary between the secure network and external networks. This gateway acts as a mediator that all communications must pass through, enabling centralized security control, auditing, and protection against sophisticated attacks while maintaining network connectivity.
Solution Approach 2:
The system implements comprehensive logging and auditing mechanisms that capture all communications passing through the gateway. This feedback mechanism allows for real-time monitoring, detection of malicious activities, and post-event analysis, enabling the system to identify and respond to sophisticated attacks including encrypted and 0-Day attacks.
2Reliability
If dedicated terminal servers farm is created to secure data, then high security is achieved, but network costs and infrastructure requirements increase significantly
Solution Approach 1:
The patent merges multiple security functions (firewall, proxy, auditing, encryption, and gateway control) into a single gateway server system. This consolidation provides enterprise-grade security previously requiring dedicated terminal servers while reducing infrastructure complexity and costs.
Solution Approach 2:
The gateway server is designed as a multi-functional system that can handle various types of communications (web browsing, file transfers, email) and provide multiple security services simultaneously. This universal approach replaces the need for specialized dedicated servers for different functions.
3Loss of information
If comprehensive auditing and logging of all user activities is implemented, then complete security monitoring is achieved, but system complexity and processing overhead increase
Solution Approach 1:
The patent extracts the auditing and logging functions as separate, dedicated components within the gateway system. By isolating these functions, the system can implement comprehensive monitoring without complicating the core communication handling, allowing for efficient parallel processing of traffic and audit logs.
4Object-affected harmful factors
If encryption and obfuscation methods are used by attackers to hide malicious intent, then attack detection becomes more difficult, but security controls can still be implemented through gateway-based validation
Solution Approach 1:
The gateway implements preliminary validation and inspection of communications before they enter or leave the secure network. By performing security checks, auditing, and protocol validation in advance, the system can detect malicious activities including encrypted attacks before they compromise the network, rather than reacting after infiltration occurs.

AI summary
A system and method for prevention of data leakage, the system comprising: a server configured to receive and transmit user activity commands; a protection module configured to validate and reconstruct commands received from the server and to transmit the validated reconstructed commands, the protection module further configured to create a security image associated with a specific user; and a secured transmission module configured to transmit the security image to the server while ensuring that the security image is sent securely to the associated user, wherein the server is further configured to receive the security image via the secured transmission module and to present the security image to the associated user.
