Web applications and Secure SHell (SSH) logins are initiated with remote login Services. Remote login services are attacked with Brute force and dictionary attacks. Password Guessing attacks are initiated by Botnets. Automated Turing Tests (ATTs) is conducted to identify automated malicious login attempts. Pinkas and Sander (PS) and Van Oorschot and Stubblebine proposals (VS) are used to limit the online password guessing attack based on ATTs. The PS protocol reduces the number of ATTs sent to legitimate users. The VS protocol reduces the security overhead with the significant cost of usability. Security, usability and user interface factors are considered in the remote login process.
