Make sure your SQL Server database host is located in a locked room with controlled access, your host server uses redundant power, and the data center has fire protection systems unique to a computer environment. Don’t just assume that this is the case at your organization. Verify these requirements are in place yourself or confirm it in writing with your infrastructure administrator responsible for your database server.
Also take a look at the hardware strategy involving the database server. Security is about protecting your systems and databases from hackers, but also about the availability of the database. You should verify the system is using RAID or some other disk-mirroring solution. Also investigate the disaster recovery plan and determine what would happen if your database server crashed. What is the plan for getting your system recovered and available to the users? If you aren’t involved in the planning and documentation of the Incident Recovery Plan, talk to your supervisor and get involved today.
