RE: How to keep "root" out?

We assume the SA don't know much about Oracle. But if some one is particularly interested in getting into the database, he might be on this list as well learning all our defense mechanisms. :) Or doesn't have to be subscribed to it since this list is mirrored other places and google is his friend. I think the bottom line is, if you absolutely don't want the data to be seen, encrypt it.  

My 2 cents.

Something that has not been suggested - migrate your database to 9.2. Connect as internal goes away.  

Other than that, I think the best suggestion you got was a conversation, and granting access to the v$ tables thru a specific account for that person.

And then put a long trigger in place tracking all connections to the database. Keep track of all SYS connections. At least you know when things happen. And periodically review the init.ora file for the database to make sure that nobody changes anything.  

Good Luck!

But someone determined to get in the database can simply edit sqlnet.ora

Put sqlnet.authentication_services = none in your server's sqlnet.ora. Then everyone has to use a password.   


Just for grins, I'll ask this question... Is there any way to keep the Unix "root" user from logging into the database (i.e. connect internal or / as sysdba)? Currently using on Solaris 8 here.   

We have a couple people in our Unix admin group that feel the need to "help" by writing their own DB monitoring scripts. Of course, they don't know what they're talking about. They do not have formal logins for the database, but since they are root users they are connecting via "connect internal". This is not only counterproductive but actually a potential security issue--just because someone has root doesn't necessarily entitle them to see the data in the database. What if it is a payroll database?   

So, I'm curious, is there any way to prevent access via "connect internal" or "/ as sysdba"?   

Thanks in advance.
