database access & asp.net

If a user has permissions to add and delete rows from a table i.e. adding
and removing items from an order what is to stop a malicious user changing
the product code in the form and then adding to or removing items to/from
another user's order ?
How do we ensure that the rows the user is editing are rows the user has
permission to edit ?
ThanksTwo words Application Architecture. Seriously you need to implement your
own security model if you want to provide for row level and field level
security.
Secondly if you are developing a web app the user should not have rights to
your database. The connection should be handled by an "Application User"
that in turn is managed by a Connection Pool.

row level security in your database. It has been my experience that if you
want granular security you will need to implement it on your own.
