Synopsis:

This course aims to teach students cybersecurity fundamentals by combining penetration testing with defense strategies. Using an innovative blend of lectures and practical tutorials, students engage in highly interactive classes. Each new concept is immediately reinforced with hands-on exercises, allowing students to apply what they have learned in real-time.

Throughout the semester, the course integrates both attack and defense techniques. In realistic scenarios accessed via a cyber range, students will practice a wide range of skills: reconnaissance, scanning, exploiting vulnerabilities, privilege escalation, lateral movement, exfiltration, malware analysis, network security forensics, binary reversing, log analysis, intrusion detection systems, honeypots, and applications of machine learning and AI in cybersecurity.

Classes are in English. Teachers speak English, Czech, Spanish, Greek, and Bosnian.

Requirements:

Basic knowledge of how to operate Linux systems. You should be able to complete at least the first half of the Bandit challenge levels (https://overthewire.org/wargames/bandit/).

Basic knowledge of Internet operations and networking

Fluent knowledge of how to use SSH (connect, copy files through and from)

What equipment student needs:

Computer to take the class and participate in the assignments

A laptop that can connect to the Internet, able to SSH, and install new software

An SSH client installed

Wireshark installed (https://www.wireshark.org/download.html)

What Students Will Be Provided With

Detailed weekly coursebook with all the theory, commands, and tools used in class

Live video stream and recordings of every class and recordings of previous years

Access to the class cyber range to conduct the assignments and exercises

Access to a chat system to ask questions before, during, and after class
