sql server - Restrict Full access to certain User of Database - Database Administrators Stack Exchange


the scenario following:

  • given sql server instance created , handled not me
  • creation of database , user on given instance me

question:

to limited understanding, sa login have full access database. there way can create user user/login have full access database, despite fact don't own instance?

if trying prevent owner of instance or windows or sql server administrators being able access database, the answer no.

essentially should assume administrator on box owns , can gain access on box, including database.

you may able protect actual data in cases (check out always encrypted in sql server 2016, example), that's it. administrator can access don't encrypt (and of stuff in current versions), drop database, lock out, etc.

if don't trust service provider that's hosting database, should host elsewhere. after all, host worth salt should have agreements in place legally protect you, though not physically, internal data breach.
