Learning pathway
Cybersecurity Foundations
The systems knowledge security assumes, then the defensive practice built on top of it.
Potential prerequisites
- Basic computing confidence
- Patience for hands-on lab practice
Intended audience
Who this is for
- IT and support professionals moving toward security
- Developers who want to build more defensively
- Career changers prepared to build systems fundamentals first
Learning objectives
What you should be able to do
- 01Explain how traffic moves across a network and where it can be observed
- 02Read logs and identify what is worth investigating
- 03Model threats against a system you are responsible for
- 04Apply identity, access and configuration hardening basics
- 05Write a finding that an engineering team can act on
Suggested modules
A sequence that builds on itself
Each module assumes the one before it. Skipping ahead usually costs more time than it saves.
- Module 01
Networking fundamentals
Protocols, routing, DNS, TLS — the layer most security questions reduce to.
- Networking
- Module 02
Operating systems and identity
Permissions, processes, authentication and the privilege model underneath them.
- Operating systems
- Identity and access
- Module 03
Threat modelling
Thinking about a system the way an attacker would, before anything is built.
- Threat modelling
- Risk
- Module 04
Detection and logging
What to log, how to search it, and how to tell signal from the usual noise.
- Log analysis
- Monitoring
- Module 05
Common vulnerability classes
Injection, broken access control, misconfiguration and supply chain exposure.
- Application security
- Module 06
Incident response basics
Containment, investigation, evidence handling and the write-up afterward.
- Incident response
- Documentation
Practical exercises and projects
What you build along the way
The projects are the point. They're what you can show someone afterwards.
- Project 01
Home lab
Build a small network with a vulnerable host, attack it, then defend it. Document both sides.
- Project 02
Threat model of something real
Model a system you actually use and write up the exposures you find.
- Project 03
Capture-the-flag write-ups
Work through practice challenges and publish clear explanations of your reasoning.
Suggested progression
Where it leads next
- Defensive operations and detection engineering
- Offensive testing and red teaming
- Governance, risk and compliance, or cloud security architecture

What this pathway serves
- CybersecurityFind weaknesses before someone else does, and help organisations respond when something goes wrong.
- Software DevelopmentDesign, write and maintain the systems people use — most of the job is reading and changing what exists.
- Business and OperationsKeep the machine working and improve it — the roles that hold an organisation together.
