AD Security 101: Lock Down Risky User Rights

DC security essentials: promotion changes a server's logon model and access must be tightly restricted. GPOs linked to the Domain Controllers OU affect all DCs, so mistakes are high-impact.

Twelve AD security best practices: minimize privileged users, secure admin accounts, modern password policies, disable SMBv1, restrict NTLM, plan recovery, use SID filtering, and monitor activity.

GPO logon scripts automate logon tasks, but sprawling, poorly maintained GPO structures invite abuse. Covers how scripts work (scripts.ini) and how to secure them.

A Clang hardening cheat sheet: fortify source, strip/debug flags, ASLR/PIE and related compile- and link-time protections, filling a gap since most hardening guides focus on GCC.

A domain controller should do one thing: control the domain. Why ADDS belongs on a DC and which roles, tools, and apps to keep off it to shrink the attack surface.

Semperis argues AI-driven attacks are outpacing identity teams as machine identities outnumber human ones 10:1, and urges building organization-wide cyber resilience around hybrid identity protection before the next crisis.
