If you have unauthorized changes being made to the database, this is going to come down to poor database security.

If your application is allowing these changing, whether or not you catch this person is going to depend on how your application connects to the database. If it's a single username specified in the connection string, you're not going to be able to tell who is making the changes, from the database side anyway, because all changes are made by the same user, the one you specified in the connection string.

If, on the other hand, everyone connects to the database using their Windows account, then its possible.

Or, are they making changes using a database tool? Identifying the user will only be possible depending on the account used by the tool to login to the database. If someone is using a generic admin account, like "sa", you're never going to find this person.

Again, this comes down to poor security practices.
