Administrator accounts need to be protected at all costs. This is why there are tiering rules, which mean that tier 0 admins only log on to tier 0 computers and tier 1 admins log on to tier 1 computers. Once this is broken, lateral movement and privilege escalation attacks can occur. There are certain controls and behaviors that every organization needs to follow in order to maintain these “Tiering rules”, which will help them secure their environments. Let 20X Microsoft MVP Derek Melber guide you through the best practices on what you need to do in order to help secure your administrative users and maintain your tier 0 and 1 framework.

You will learn:

  • What are the different tiers
  • Why tiering is so important to secure your enterprise
  • How tiering can reduce your attack surface
