Basics - IT-Security

Nowadays, sensitive data is in electronic form processed in every company. If the protection of this data is at risk, this poses an essential threat to the company’s operational business. The participants are given the tools to recognize and assess these risks and to initiate appropriate countermeasures.

The central idea of this course is to provide network administrators, security representatives, executives and employees who process sensitive data with the basics for their work in handling confidential information and the basics of network security. General principles, best practices and attack techniques are presented. Numerous “live hacking” examples illustrate the theoretical explanations.
