Oracle: Tracking failed logon attempts

    http://www.dba-oracle.com/t_tracking_counting_failed_logon_signon_attempts.htm
    Answer: Yes, it is difficult to audit failed sign-on attempts because the user never gets connected to Oracle, and a logon trigger would not be useful because it requires a valid login, not just an attempt. For complete directions on auditing Oracle failed sign-on attempts, see my book "Oracle Privacy Security Auditing".
