Building a Computer Network Test Lab

This course will help you build your own computer network testing environment, let it be a simple Active Directory, Splunk for log collection, Intrusion detection, Windows or Linux operating systems.
You can implement all or only a few of the systems we are going to discuss during the course depending on your needs and the resources available. I recommend using a local virtualization technology with 16GB RAM minimum, like vSphere, VMware Workstation, Virtualbox, or similar.
The second subnet will be the one for collecting logs and for forensics computers.

The training will cover:

1. installing different operating systems, like Windows 7, Windows 10, Windows Server 2016, Windows Server 2019, Ubuntu Linux, CentOS Linux.
2. installing security appliances: Security Onion, AlienVault OSSIM.
3. learn installing and configuring OPNsense firewall by separating
4. installing and configuring services: Active Directory, Splunk SIEM, OPNsense firewall, time sync using NTP.

This will allow you to test out solutions without the risk of damaging a production environment.
The course is giving you directions on how to set up these systems and will show you one use case at this time. I will continue adding more content as I develop more, and update the content based on feedback.
The training is not focusing on lexical knowledge and is not explaining what the different tools are doing in general. I assume that you either Google those or already have an idea about each solution. For example, I am not going to explain in detail what a SIEM is used for. We are going to set it up and use it.
This training is focusing on giving you the technical knowledge to be able to get systems up and running as quickly as possible and work with each other in a network.
