O121-BP-021900 - The Oracle REMOTE_OS_AUTHENT parameter must be set to FALSE.


Setting this value to TRUE allows operating system authentication over an unsecured connection. Trusting remote operating systems can allow a user to impersonate another operating system user and connect to the database without having to supply a password. If REMOTE_OS_AUTHENT is set to true, the only information a remote user needs to connect to the database is the name of any user whose account is setup to be authenticated by the operating system.


Document remote OS authentication in the System Security Plan.

If not required or not mitigated to an acceptable level, disable remote OS authentication.

From SQL*Plus:

alter system set remote_os_authent = FALSE scope = spfile;

The above SQL*Plus command will set the parameter to take effect at next system startup.
