Access Control Security (Global)
High-quality technical overview of Access Control Security in the context of blockchain security.
Key components of AD include: 1. Domains: A logical group of objects. 2. OUs (Organizational Units): Subdivisions for applying specific Group Policies. 3. GPO (Group Policy Objects): Templates for managing system configurations. 4. FSMO Roles: Flexible Single Master Operation roles that handle specific critical tasks like schema updates or RID allocation.

Think of [Active Directory](/es/terms/active-directory) like a giant, interactive phonebook for a whole company. It doesn't just have names and numbers; it also knows which employees have the 'key' to which office doors, which printers they can use, and it lets them sign in once to access everything they're allowed to touch.
🤓 Expert Deep Dive
Under the hood, AD is implemented as an Extensible Storage Engine (ESE) database called NTDS.DIT located on Domain Controllers. It operates using a multi-master replication model, where changes on one DC are propagated to others. Advanced security relies on the KDC (Key Distribution Center) representing the Kerberos auth flow. A critical modern concern is the 'Privileged Identity' lifecycle—protecting administrative accounts from 'Pass-the-Hash' attacks and securing the 'Trust Relationships' between different domains in a forest.
