Cybersecurity is easier to understand once you know the layers underneath it. Learn in order — understand, observe, practise, then connect the pieces.
Each subject helps you understand the next one. The goal is not to memorise terms — it is to understand enough to solve real problems.
Understand what the protocol or system does.
See what packets, logs and CLI output are telling you.
Test the concept with questions, scenarios or a lab.
Connect each topic so the network makes sense as one system.
If you are completely new, start with Networking. If you already have a foundation, start where your current gaps are.
Start from the basics: IP addresses, packets, switching, routing, network services and troubleshooting.
Understand how network traffic moves before you learn how to secure it.Learn to control network traffic: firewalls, policies, NAT, VPNs, segmentation and security operations.
Learn to reason about what traffic should be allowed, denied, inspected and logged.Learn how attackers think and work — reconnaissance, enumeration, testing and security validation.
Understand how an attack unfolds, without skipping the fundamentals for tools.Networking, Network Security and Ethical Hacking are the starting stack — not the finish line. New practical tracks will be added once they meet the AddySec standard.
Expect deeper firewall, Linux, automation and modern security learning over time.Once a concept makes sense, test it. Use MCQs for recall, scenarios for judgement, troubleshooting for diagnosis and labs for hands-on practice.
Networking, Network Security and Ethical Hacking are the starting stack. Every release adds more depth to the same connected system.
