What can be done to prevent SQL injections in a database?
Ensure input validation is used to authenticate users
Design database to overflow redundant data into backup
Design database to accept SA account access
Ensure authorized users have the most privileges
System administrations (SA) should never have database access. All user access should be based on the least privileges. Databases should be designed to not accept redundancy. Input validation will prevent all forms of SQL injections from outside parties since they will need to authenticate.
