Description
SQL Server's default 'sa' account has special privileges required to administer SQL Server. The default 'sa' account is a well-known SQL Server administrator account and is likely to be targeted by attackers and thus more prone to providing unauthorized access to the database. This 'sa' default account is administrative in nature and could lead to catastrophic consequences including the complete loss of control over SQL Server, not to mention a compromise of user data. If the 'sa' default account's password is not changed an attacker might be able to gain access through the account.
