Prevention of Online Password Hacking Process with Secured Multi Authentication Scheme

Online guessing attacks on password-based systems are inevitable and commonly observed against web applications and SSH logins. In nowadays report, SANS identified password guessing attacks on websites as a top cyber security risk. An example of SSH password-guessing attacks, one experiment Linux honey pot setup has reported that it suffered on average 2,810 SSH malicious login attempts per computer per day. Interestingly, SSH servers that disallow standard password authentication may also suffer guessing attacks, e.g., through the soaking of a lesser known/used SSH server configuration called keyboard interactive authentication. However, online attacks have some implicit disadvantages compared to offline attacks: attacking machines must engage in an synergistic protocol, thus allowing easier detection.
