Abstract

A detection device and a detection method for a malicious HTTP request are provided. The detection method includes: receiving a HTTP request and capturing a parameter from the HTTP request; filtering the HTTP request in response to the parameter not matching a whitelist; encoding each character of the HTTP request to generate an encoded string in response to the HTTP request not being filtered; generating an estimated HTTP request according to the encoded string by using an autoencoder; and determining that the HTTP request is a malicious HTTP request in response to a similarity between the HTTP request and the estimated HTTP request being less than a similarity threshold, and outputting a determined result.
