Build tools that
cross job titles.
Bring the Cyber Security, Sysadmin, and Network Admin paths together. Build a TCP port scanner and practise Windows administration against a simulated fleet.
This is the next stage after the three intermediate role courses, building on The Basics and their shared skills in analysis, administration, and networking. The advanced lessons are coming soon.
Build a TCP port scanner
Take an explicit host and port list, attempt TCP connections, and return useful objects with open, refused, timed out, or error outcomes.
- Validate inputs and bound each connection attempt
- Separate probe logic from reporting
- Test timeouts and failures with simulated probes
- Compare results with an expected service inventory
A shared tool for service-exposure reviews, expected-listener checks, and network troubleshooting.
Explore a simulated Windows fleet
Practise operating-system and remoting patterns with a clearly labelled lab environment that supports all three roles.
- Query OS, processor, and memory details
- Inspect running processes and stop simulated processes
- Preview changes with WhatIf and preserve lab state
- Run script blocks on simulated remote computers
- Handle offline hosts and access-denied outcomes
The remoting lessons will explain WSMan and PowerShell Remoting concepts while keeping browser execution inside the simulation.
