Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions lack a comprehensive method to evaluate and assess network steganographic effectiveness across multiple exfiltration methods, requiring numerous individual tests to determine the defenses against various steganographic attacks, and fail to quantify the impact on network communication reliability and performance.
Innovation Solution
A system for network steganographic integration that sends and receives steganograms using multiple methods to conduct assessments, allowing for a single test to evaluate the effectiveness against various exfiltration methods and measure the impact on network communication reliability and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple individual tests are conducted to evaluate defenses against various steganographic attacks, then comprehensive assessment coverage is improved, but test complexity and time consumption increase
Solution Approach 1:
The patent combines multiple individual steganographic tests into a single integrated assessment system. The system simultaneously evaluates multiple exfiltration methods (storage channels, timing channels, parity channels, sequence channels) and multiple defense mechanisms (detection, prevention, correction) in one unified test execution, rather than requiring separate tests for each combination.
Solution Approach 2:
The assessment system is designed with multi-functionality to handle various steganographic methods and defense types through a single universal platform. It can assess storage channels, timing channels, parity channels, and sequence channels using the same infrastructure, eliminating the need for separate specialized test systems for each method.

Solution Approach 2:
The assessment system operates continuously by executing multiple test cases in sequence without requiring reconfiguration between tests. The system maintains continuous operation through automated test case management, allowing uninterrupted assessment of multiple steganographic methods and defense mechanisms in a single assessment session.
3Measurement precision
If comprehensive assessment of network steganographic effectiveness is achieved, then evaluation quality is improved, but system complexity increases
Solution Approach 1:
The patent segments the assessment system into distinct functional modules: test case management module, steganogram generation module, network communication module, and assessment evaluation module. Each module handles specific aspects of the assessment, making the overall complex system manageable through clear functional decomposition and independent module development.
Solution Approach 2:
The system introduces an intermediary assessment platform that mediates between the steganographic communication processes and the evaluation metrics. This intermediary layer standardizes the interaction between various steganographic methods and defense mechanisms, simplifying the overall system architecture by providing a unified interface for diverse assessment operations.

AI summary
To date, there is no method to test the network steganographic effectiveness of network security hardware or software using a plurality of attack techniques. The invention specified herein represents such a method. The present invention enables an operator to test network security products in their ability to perform in areas including but not limited to detecting steganograms, preventing steganograms, normalizing packets transmitting covert data, steganographic operation without negatively impacting the performance/reliability of a network, and other activities related to network steganography. Assertions made by network security manufacturers with regard to their network firewall and security appliances must be supported by empirical evidence. The invention described herein provides quantitative and qualitative data to support or refute manufacturer assertions that their network security hardware or software can effectively perform as claimed as it relates to network steganography.
