Active Directory and GPO5:34
Explore active directory domain services and its Azure cloud version, enabling centralized management of users, computers, and policies via domain controllers and GPO.
Authentication5:15
Explore authentication, authorization, and accounting (AAA) concepts, illustrating centralized identity with Active Directory and radius for VPN access, and differentiate standard users from local admins on Windows devices.
User accounts and passwords3:59
Manage domain users and computers on a Windows server by configuring group policy to enforce password length, complexity, history, and age, plus account lockout and Radius-based VPN access and MFA.
MFA7:41
Explore how multi-factor authentication strengthens security beyond passwords by using factors like a mobile app push, fingerprint, or location-based access, with easy hardware, software, or app options.
Audits and logs7:06
Explore how to use event viewer and Windows logs to troubleshoot security and network issues, filter Kerberos tickets, view Reliability Monitor, and audit policies via local group policy editor.
Encryption: symmetric and asymmetric6:25
Encryption and hashing7:39
Explore real-world encryption and hashing, using SHA-256 or SHA-512 to verify downloaded files. See BitLocker full-disk encryption with TPM, enable it on Windows 11, and understand DFS file-level encryption.
VeraCrypt in action5:26
Install VeraCrypt on Windows 11 from the official site, enable disk encryption, set strong passwords with random data, and note performance impacts on Windows 11 home without bitlocker.
