In order to study the performance indicators of the specialized cybersecurity products and solve the problems of performance testing, this paper studies and analyzes the national recommended standards corresponding to different specialized cybersecurity products. The performance requirements in the standards are classified into several major categories, including throughput latency, attack detection, event restoration, new connection rate and concurrent connections, which basically covered the performance requirements of all specialized cybersecurity products. According to different performance classifications, improved software testing environments and methods based on technologies such as virtualization are designed. The designed software testing methods is used to test the performance of different types of specialized cybersecurity products, and compared with the test results of hardware instruments. The designed software testing method can effectively test the performance indicators and obtain reliable test results.
