CYBERSECURITY ANALYST ROADMAP · STAGE 01 OF 04

Networking and operating-system foundations

Understand how hosts, networks, and common operating systems communicate and record activity.

What you will learn

Explain a normal network request and identify where useful security evidence may be recorded.

CORE SKILLS

Key concepts in networking and operating-system foundations

01

Network fundamentals

Learn how data moves between systems so unusual connections can be investigated in context.

Topics include

  • IP addressing and routing
  • DNS, HTTP, and TLS concepts
  • Ports and common protocols
02

Linux and Windows basics

Navigate system files, processes, users, and logs on the operating systems security teams commonly monitor.

Topics include

  • Processes and services
  • Users, groups, and permissions
  • System and authentication logs
03

Scripting and automation

Use small scripts to parse logs, normalize events, and reduce repetitive defensive analysis.

Topics include

  • Python or shell basics
  • Text and structured-log parsing
  • Safe, reviewed automation
04

Security vocabulary

Use threat, vulnerability, risk, and control precisely when describing defensive findings.

Topics include

  • Confidentiality, integrity, availability
  • Threats and attack surfaces
  • Risk and control concepts

APPLY WHAT YOU LEARN

Practical project

In a local lab or public sample dataset, document a normal web request and identify which endpoint, DNS, and server logs could help investigate an anomaly.

CHECK YOUR UNDERSTANDING

You are ready to move on when

  • Can explain the network flow without guessing from a single alert.
  • Can distinguish a suspicious signal from confirmed compromise.
