Week 4: Linux CLI Foundations

Garden State Cyber I now moves from threats into the command line.

You will learn the Linux terminal as an inspection tool: how to identify where you are, navigate files, read metadata, inspect processes, filter text, and document what you did.

This week

Lesson 1: From GUI to CLI: Read the System Directly

Learn the shell model, paths, navigation, file listing, and read-oriented commands. Compare GUI and CLI workflows without treating either interface as magic.

Lesson 2: Inspect Files, Processes, and Permissions

Read Linux permission strings, inspect process state, filter logs with grep, and connect file access to confidentiality, integrity, and availability.

Lesson 3: CLI Investigation: Build a Reproducible Evidence Trail

Work through a bounded synthetic investigation. Correlate login, file, and process evidence without modifying the lab or overstating what the evidence proves.

What you will produce

• command map
• System Snapshot
• permission reasoning notes
• command transcript
• evidence-correlation table
• defensible investigation conclusion

The goal is not terminal speed.

It is being able to say what command you ran, why you ran it, what it returned, and what the result does not prove.
