Simulating Customer Deployment Environments for Network Security Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network security testing faces challenges in simulating the customer series deployment environment, leading to poor environment applicability and incomplete testing, which affects the operation stability of security protection devices.
Innovation Solution
A test method and device that obtain traffic data from an on-site protected host, extract session data, and transmit application layer data to a local test environment for simulation, using techniques like IP address configuration, filtering with tools like Wireshark, and parsing TCP sessions to accurately replicate the customer site environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If series monitoring mode is used to test customer site environment, then the security protection device can be deployed in a realistic scenario, but it is difficult to fully simulate the same test environment due to variety of customer site environments
Solution Approach 1:
The patent creates a virtual copy of the customer site environment by capturing actual traffic data from the customer site and reconstructing it in a local test environment. This allows the test environment to replicate the real customer environment without physically being at the customer site, solving the contradiction between realistic testing and environment complexity.
Solution Approach 2:
The patent transforms the test environment from a physical customer site to a local virtual environment by changing key parameters such as location, network configuration, and data representation. This allows the same security protection device to be tested in a controlled local environment that mirrors the customer site conditions.
2Ease of operation
If bypass monitoring mode is used, then the test deployment is simple, but the testing is incomplete and environment applicability is poor
Solution Approach 1:
The patent introduces an intermediary component (the traffic data capture and processing system) that bridges the gap between the simple bypass monitoring mode and the comprehensive series monitoring mode. This intermediary captures traffic data in bypass mode but processes and analyzes it as if in series mode, achieving both ease of deployment and testing completeness.
3Measurement precision
If complete TCP session data is captured and analyzed, then the simulation accuracy is improved, but the data processing time and complexity increase
Solution Approach 1:
The patent extracts only the essential elements needed for accurate simulation (application layer data from TCP sessions) rather than processing all raw traffic data. By taking out and focusing on the critical data components, it achieves high simulation accuracy without the time penalty of processing complete raw session data.
Data Source
AI summary
A test method and device for simulating a customer series deployment environment, an electronic device, and a storage medium are provided. The test method for simulating a customer series deployment environment includes: obtaining traffic data of an on-site protected host; obtaining session data between the on-site protected host and a server on the basis of the traffic data, and extracting application layer data from the session data; and transmitting and receiving the application layer data in a local test environment to carry out simulation test.
