How to Configuring Authentication-Related Audit Policies in Windows Server 2016

By | 03/04/2018

What is Audit Authentication?

Auditing is an important security component. Windows Server 2016 domain controllers and other servers log security-related events to the Security log, where you can monitor and identify issues that might warrant further investigation. Auditing can log successful activities to provide documentation of changes. It also can log failed and potentially malicious attempts to access enterprise resources.

Infrastructure Requirement :

  • 1 Client PC running Windows 10 (CLIENT-10)

Lets get started.

01 – Configuring Authentication-related Audit Policies
