Linux/UNIX System and Network Security

This Security Bootcamp is a unique hands-on course designed to give administrators practical experience with obscure and difficult security tasks in a supportive learning environment. Theoretical knowledge is given before and after the class so lectures can focus on the important issues that administrators will face while securing their network, designing reflexive defenses, protecting users, data and services, providing incident response and performing rudimentary forensics.

This bootcamp is a fast-paced course and assumes basic Linux system & network administration expertise. There is substantial lecture work with continuous hands-on training.

The class is complemented by our e-learning website and access to our instructors before and after the class.
