Overview

In “Network Security Fundamentals” we combine fundamentals and practice: you get to know Network threat scenarios, Segmentation and DMZ and Firewall rule sets, apply what you learn in exercises and receive templates and checklists for your own use.

A stable, secure network is the prerequisite for almost every IT service, and with cloud connectivity, remote work, Wi-Fi and segmentation, complexity keeps growing. Our Network Security Fundamentals courses are aimed at network administrators, system owners and security teams who need to design, configure and secure networks and get them running again quickly after incidents. We combine protocol understanding with practical configuration: you work in a provided lab with real or virtual devices and analyze traffic yourself. The course runs online or on site, lasts one day and is offered at a fixed price per participant.

The course is delivered live – either online in a virtual classroom or on-site in our training rooms in Munich, Salzburg, Berlin, Augsburg, Hanover, Bremen, Stuttgart and Kaiserslautern. We can also run it exclusively for your team.
