Abstract: It is very important to know the version information of Web server exactly on doing computer network system security evaluation successfully. The limitation of general detection technology through the banner information is analyzed. The principle of fingerprint analysis detection technology and the element structure of Web server fingerprint information are introduced. The model and flow chart of fingerprint matching algorithm are provided. The advantages of fingerprint analysis technology on detecting version information of Web server are proved with an example.
