SQL Server Security Mechanism

Security is the protection of information through some principals.

  • Authentication is the process of logging on to SQL Server by which a principal requests access by submitting credentials that the server evaluates. Authentication establishes the identity of the user or process being authenticated.

            Authentication means “who you are”.

  • Authorization is the process of determining which securable resources a principal can access, and which operations are allowed for those resources.

            Authorization means “what you can do”.

In SQL Server supports four types security levels.

  1. Windows level security.
  2. SQL Server Instance level security.
  3. Database level security.
  4. Schema level Security.
