Hello team,

When audit_sys_operations is set to true then the every
Query by SYS is being captured , that is ok.
But my concern is that, I just want to capture
Drop user operations by SYS.

Is it possible...and if yes then pls suggest

DB version- 11.2.0.4 EE

No, either you audit everything, either you audit nothing from SYS.
I advise you audit everything. Is there any reason you don't want to do it?

In addition, SYS should NOT be used to drop a user, SYS should be used ONLY to manage the instance, and database for backup and recovery.
Fire the one that use SYS to drop a user.

And fire the one who gives quota on SYSTEM tablespace to users (see one of your previous topics).

Actually the concern is , It will catch every single query execution by SYS.

And if I use audit_trail for drop user then SYS activities will be missed out.

Here we create and manage users with SYS , so you are suggesting not to use SYS for such operation.
Please suggest why?

And that's what you should want. As stated, SYS should be used so sparingly, that you should want to audit everything done with that account.

That's exactly what is being suggested.

Because SYS is such a powerful and easily abused account. Using SYS is like walking a tightrope without a net .. while juggling chainsaws. In shops that actually care about security and integrity, use of SYS (just like use of root on *nix systems) is limited to only those tasks that cannot be accomplished with another 'admin' account.

The fact that your shop uses it as a more general admin account is clear evidence that no one there actually understands or cares about security and integrity of your system.
