From flat networks to locked up domains with tiering models

This blog post reviews common Windows privilege-escalation and lateral-movement techniques (LSASS credential dumping, Pass-The-Hash, token impersonation, RDP shadow/shadowing, scheduled-task credential prompts, and certificate/PFX abuse) and argues that endpoint tools alone are insufficient. It recommends practical tiered network architectures (including a T-1 backup/hypervisor separation, isolated admin networks, bastions/RDS usage, private VLANs, and dual-forest designs) and operational controls to limit privilege flow, contain compromises, and protect backups.
