oracle priveleges

Aside from the DBA role privs set in DBA_ROLE_PRIVS, are there any othe rdefault priveleges that are "high risk" if granted to the wrong person, if so can you provide some other dangerous privelege that we should check for and the types of permissions they would allow to the users to do in your database. I guess DBA role is the highest privelege, as SYS and SYSTEM get it?

Users and/or application roles should never be granted privileges with the word ANY in them.  That also goes for PUBLIC.

Rule of thumb is minimal privileges.  Nobody should have privileges they don't need "just because".  Laziness on the part of developers/designers to determine which privileges are necessary are not an excuse.

SYSDBA is the highest.

>>that are "high risk" if granted to the wrong person,

I agree with the above post about minimal.  You also need to be aware of some out of the box permissions that might be dangerous.

Sorry but I don't have an exhaustive list nor have I seen one.

For example:  We have to manually revoke execute from PUBLIC on the following packages for every database:

Then manually grant execute specifically to the users that need them.

The reason:  Many of these have potential 'holes' or outright concerns that might be exploited.

Thanks - I did have some docs on the packages, I could never really understand why DBMS_RANDOM was a security issue though - can you shed any light? I know some of the others listed allow for access outside the DB and on the OS/file system etc., and I guess some like DBMS_SQL may allow for elevation or priveleges etc, i. basic user running queries under the context of a DBA.

Never bothered to look it up.  I just follow orders...  ;)

Even if I had Larry Ellison himself tell our security folks that dbms_random is "safe", I would still have to revoke it.

Looks like someone wrote a book on the subject.  From the explanation there, it sounds believable.

Is it "true"?  It has to be, I found it on the Internet...
