Especially, Stick to the principle of minimum privilege when producing person accounts into a SQL database. The databases people ought to only have the minimum amount privileges required to use their account. If the necessities of the process suggest that a consumer can read through and modify their unique knowledge, then Restrict their privileges so they can't browse/publish Some others' my explanation facts.
