Our Master Class Active Directory Security workshop at a glance

Become an Active Directory security expert! This five-day workshop provides the practical know-how needed to implement an Active Directory implementation that both resists known attacks and is hardened against future attacks.

After attending this course you will have no (!) more questions about Active Directory security – I promise!

About the seminar

This workshop takes a close look at Active Directory security. Meanwhile, various attack scenarios are known (e.g., mimikatz) that target credential theft or ransomware implementation. The goal of this workshop is to understand these scenarios so that you can then prevent them and implement an Active Directory implementation that resists these attacks and is also hardened against future attacks. Active Directory are your “crown jewels” – without Active Directory, most corporate environments are completely crippled in production. Therefore: understand, harden and monitor so that you can sleep better.

Requirements

Attendees should have at least five years of experience with Active Directory and client systems.

Target group

The workshop is aimed at network administrators and security experts.

Training environment

The training runs completely virtualized. Each participant has a PC with 128 GB RAM, two NVME SSDs (throughput read up to 3,500 MB/s, write up to 2,300 MB/s) and a total bandwidth to the Internet of 1 Gbps.

Each participant “builds” his environment completely by himself with the trainer. With the appropriate hardware, new systems can be set up in seconds.
