Brute force and dictionary attacks on password-only remote login service are very common and it is on the rise. Preventing such attacks by hackers is a complex problem. Automated Turing Test is an effective solution to identify and prevent automated malicious login attempts with minimal difficulties to users. In this paper, we discuss the insufficiency of existing and proposed login protocol designed to address extensive online dictionary attacks. We propose a new Enhanced Password Guessing Resistant Protocol (EPGRP), derived from revisiting prior proposals designed to restrict such attacks. While EPGRP limit the total number of login attempts from unknown remote hosts to as low as single attempt before being challenged with ATT. For enhancing the security, a One Time Password is also used in addition to ATT.
