5.SEC_MAX_FAILED_LOGIN_ATTEMPTS
You can limit the number of failed login attempts for application connections by setting the SEC_MAX_FAILED_LOGIN_ATTEMPTS initialization parameter to restrict the number of authentication attempts on a connection. After the specified number of authentication attempts fail, the database process drops the connection. By default, SEC_MAX_FAILED_LOGIN_ATTEMPTS is set to 10.
Remember that the SEC_MAX_FAILED_LOGIN_ATTEMPTS initialization parameter is designed to prevent potential intruders from attacking your applications; it does not apply to valid users. The sqlnet.ora INBOUND_CONNECT_TIMEOUT parameter and the FAILED_LOGIN_ATTEMPTS initialization parameter also restrict failed logins, but the difference is that these two parameters only apply to valid user accounts.
