Dear Gurus

I create a user EXP for backup therefore I give him privileges
CREATE SESSION
EXP_FULL_DATABASE

but the problem is I don't want to connect this user by SQL or anyother tool because if somebody know the password then he/she couldn't use SQL.

Please help me in this regards.

You may need to write database trigger.

It is a privilege issue.
It is very difficult to write an On-Logon trigger that will stop a knowledgable user rfom circumventing the trigger by renaming the executable that they are using.

Yes you're correct Mr Jrow. I mistakenly understand. Sorry for that.

Then make the password really difficult. QED.

You do know that Exports aren't backups, don't you?

You can restrict access to Sql*Plus via Product User Profile, but that won't help for other SQL programs.

I just do not understand the concern.
You trust the user and give permission to do a full export.
The user can get the data out of database and do whatever with it.
But still worry about querying the DataDictionary views?
As JRowBottom already suggested,
You gave the permission. You cannot stop a user with right knowledge to circumvent everything.

It's not just the data dictionary tables - EXP_FULL_DATABASE looks like it grants you SELECT ANY TABLE.

Yes. That's right and EXECUTE ANY is also included.
My point is, If user is allowed to get ANY data out, it better be a trusted user.
EXP and IMP_FULL_DATABASE gives a wide range of privileges.
