Authentication policies and authentication policy silos
The basic rule in PtH attack protection is to prevent trusted users from appearing on untrusted systems. Rebeladmin Corp. uses an MS SQL farm to run its databases. During the SQL Server setup, engineers use service accounts. It is obvious that these SQL service accounts should be used only with SQL Server. If the accounts appear on a receptionist's computer, something is definitely wrong. With Windows Server 2012 R2, Microsoft introduced authentication policies and policy silos that can be used to limit the use of highly privileged accounts to selected systems.
