Abstract
A referer verification apparatus and method for controlling web traffic having malicious code are provided. In the referer verification method, whether a referer is present in a Hypertext Transfer Protocol (HTTP) packet is determined. If it is determined that the referer is present in the HTTP packet, Uniform Resource Locators (URLs) are extracted from a referer web page corresponding to the referer. The referer is verified based on a URL corresponding to a referer verification request received from a server and the extracted URLs. A Completely Automated Public Test to tell Computers and Humans Apart (CAPTCHA) verification procedure conducted by a user is performed based on results of the verification of the referer.
