Hi Davis & Pete Finnigan,

Thank you so much for your response. Let me go through Pete Finnigan's security related white papers.

The type of attack you are suggesting is a problem that exists with all systems not just Oracle databases. For example an attack against a system administrator/application owner account on any platform (Windows, Mainframe, Unix, Database) could all potentially be shutdown by too many logon attempt failures.

Often, with these type of accounts you cannot apply the same password mgmt rules (3 strikes and you are out). But having violation alerts/notification for attacks (ie. Audit trails) requirement for complex passwords that can withstand brute force attacks (eg. dictionary searches).

I would suggest following Pete Finnigan's advice would be prudent. He knows what he is talking about when it comes to security. I have a copy of the Oracle Security Step-by-Step guide he mentioned which is only available from the SANS Institute (SysAdmin, Auditing, Networking & Security).

If you work for a large corporation you will probably have a security officer. It might be a good idea to talk to them.

btw Drake over reacted and was I thought very rude. I think Drake felt your question was best asked on a secured forum.

Cheers
