Questions and Answers

What is the primary purpose of Active Directory (AD)?

To provide a centralized authentication and authorization service

To monitor and detect cybersecurity threats in the network

To manage user accounts and access rights across multiple domains (correct)

To store and manage network resources and configurations

What is the relationship between a domain and an Active Directory forest?

A domain is a standalone entity that is not part of any AD forest

A domain and an AD forest are the same thing, and they are used interchangeably

A domain is a subset of an AD forest, and a forest can contain multiple domains (correct)

A domain is a logical grouping of users and resources, while a forest is a physical infrastructure

What is the primary role of a Domain Controller (DC) in Active Directory?

To monitor and detect cybersecurity threats across the entire AD environment

To provide a centralized authentication and authorization service for the entire AD forest (correct)

To store and manage all network resources and configurations

Study Notes

Active Directory (AD) Basics

An Active Directory (AD) must have at least one Domain Controller (DC) to function.
Domain Controllers are containers for domains, and each domain is part of an AD Forest.
An AD Forest can include one or more domains, which are organized into Organizational Units.

Active Directory Domain Services (AD DS)

AD DS manages trusts between multiple domains, allowing access rights to be granted to users in one domain to access others in the forest.

Importance of Active Directory in Cybersecurity

A deep understanding of Active Directory is crucial in modern cybersecurity.
Attackers often target AD to infiltrate, laterally move, and exfiltrate data within a network.
AD logs can reveal "breadcrumbs" of attacker activity, providing valuable insights for threat detection.

Varonis and Active Directory Monitoring

Varonis monitors AD for signs of malicious activity, including file activity, DNS calls, VPN activity, and more.
Varonis correlates collected data to create a comprehensive picture of user and computer activity in AD.
This correlated data is compared to a normalized baseline and a catalog of data security threat models to proactively identify potential threats to data.
