Cybersecurity Lab Exercises

This repo contains my notes and write-ups of all the practical labs I worked on during the course "Cybersecurity Advanced" at HOGENT.

If this is useful to a student, you're welcome! But just keep in mind that you won't learn anything unless you try stuff out (and fail) yourself ;)

Topics

The course covered many topics, including:

• Enumerating, analysing & segmenting an existing network
• Configuring host-based & network firewalls using nftables
• creating a ssh client config to properly manage all machines
• configuring suricata as an IDS
• setting up a SSH Honeypot
• implement a backup solution using borgbackup
• setting up a SIEM (Wazuh) and monitor Linux & Windows clients
• creating IPSec & OpenVPN tunnels
• utilising ansible for system hardening & threat hunting
