Study Notes
Active Directory: Comprehensive Guide to Domains, Organizational Units, Group Policy, Users, Groups, and Trust Relationships
Introduction
Active Directory (AD) is a comprehensive directory and identity management solution developed by Microsoft. It provides centralized authentication and authorization services to manage network resources, including workstations, servers, applications, and printers. Active Directory relies on various components like domains, organizational units, group policy, users and groups, and trust relationships to maintain secure and efficient access to resources.
Domains
Domains define the boundaries for trust relationships in Active Directory. Within a domain, all users, computers, and security principles have common security policies, standardized configurations, and naming conventions. Domains facilitate easier administration and control of resources. There are two main types of domains: workgroup and domain. Workgroup domains do not have a dedicated domain controller, whereas domain domains rely on a hierarchy of domain controllers for authentication and authorization.
Organizational Units
Organizational Units (OUs) serve as containers for grouping similar objects in Active Directory, such as users, computers, or other OUs. They offer flexibility in assigning permissions and applying group policies. Administrators can easily modify settings, apply policies, and delete OUs by changing the parent OU they belong to. OUs help simplify management tasks and reduce complexity in larger environments.
Group Policy
Group Policy is a feature in Active Directory that allows administrators to centrally manage and enforce security policies, software updates, and application settings. It provides granular control over endpoints, ensuring standards compliance and improving overall security posture. Group Policies can be applied to individual users, computers, or entire OUs based on specific criteria.
Users and Groups
Users represent human beings or entities interacting with Active Directory resources. Each user account contains a unique Security Identifier (SID), providing a fixed value for authentication purposes. Security groups, on the other hand, are collections of users, computers, or other groups, designed to simplify the assignment and management of permissions. Administrators can grant or deny access to resources by adding or removing users and groups to or from these higher-level structures.
Trust Relationships
Trust relationships establish connections between domains or forests in Active Directory, allowing controlled access to resources shared between them. There are several types of trusts, including:
- Forest trusts: These two-way relationships connect entire forests to facilitate communication and access between domains.
- Domain trusts: One- or two-way connections between specific domains, allowing users in one domain to access resources in another.
- Shortcut trusts: Improve network performance by reducing the number of hops required for authentication when a user logs onto a resource in a different domain or forest.
- Realm trusts: Enable authenticated communication between Microsoft Windows computers and Kerberos realms.
Trust relationships are established through explicit authorization, manual configuration, or automatically upon creation of new domains. Trust relationships can be transitive (allowing indirect trust over multiple levels) or non-transitive (requiring direct trust), as well as one-way or two-way.
In conclusion, Active Directory's components such as domains, organizational units, group policy, users, groups, and trust relationships work together to provide comprehensive identity management solutions that enable secure and efficient access to network resources.
