The SQL Server Agent runs by default under the SQL Server system account security credentials. If you do not want to run SQL Server Agent jobs under SQL Server system account security credentials, you can create a proxy account to run SQL Server Agent jobs in a security context with lower rights. For additional information about running the SQL Server Agent using a proxy account, see the SQL Server documentation on the Microsoft SQL Server TechCenter (http://go.microsoft.com/fwlink/?LinkId=58494).
