Abstract

A harmful URL detection method is proposed. The method includes requesting entry to a web page to which access is sought from a user terminal, comparing an access target URL corresponding to the entry-requested web page with a pre-stored whitelist, excluding the access target URL from a detection target when an identical domain exists as a result of the comparison with the whitelist, checking whether the access target URL refers to a previously accessed web page when the identical domain does not exist, excluding the access target URL from the detection target in a case of the previously accessed web page, checking a response code for the access target URL in a case of a web page not previously accessed, and excluding the access target URL from the detection target when the access target URL is abnormal in communication according to the checking of the response code.
