Hacker - Defending Active Directory Against Cyberattacks

Here is a very interesting Microsoft Virtual Academy about Active directory Security.

Interested in the why, how, and what of Active Directory (AD) and enterprise protection? This course has the answers you need to help you defend AD against cyberattacks. Learn from the experts, as they look at Active Directory from an enterprise risk perspective. The key to success is knowing what your high-value assets are, securing them, and securing their dependencies.

Whether your digital assets are on-premises or in the cloud, join us to explore the AD environment, today’s adversaries, relationship dynamics, and strategic prioritization, along with adoption of least privilege. Take a look at the different aspects of Active Directory security, based on findings from the Microsoft Cybersecurity Services team, learn strategies to protect privileged identities in your environment, and finish the course with a roadmap for hardening your AD environment. Defenders should be as extremely adaptive as adversaries are these days, and this course is a great place to start.
