Browser's "search form" issues and countermeasures
須賀祐治(IIJ)
In this paper, the survey targeted are the websites of regular members belonging to the association which is planning and managing settlement systems of banks and on-line banking login services. We investigated SSL/TLS sites of Top FQDN which are widely announced on paper medium etc, so it was found that about half of them were in normal situation but half had problems such as FQDN mismatch. Moreover we also show the result of manually investigating the influence of the above "search form" issues by carrying out some pattern classification on the path reached from the HTTP (not HTTPS) server of the Top FQDN to the on-line banking login page. Finally, the design guideline of HTTP/HTTPS sites is mentioned as one of countermeasures against this kind of problems.
