1. 01Module 1 — Welcome to the Blue Team

   Discover the role of defensive security teams, SOC analysts, security engineers, incident responders, and threat hunters within a modern cybersecurity organization.

2. 02Module 2 — Building a Defensive Mindset

   Learn how defenders think about assets, attack surfaces, threats, vulnerabilities, risks, and security controls.

3. 03Module 3 — Security Hardening

   Learn the fundamentals of securing systems, applications, accounts, networks, and endpoints by reducing unnecessary exposure and strengthening configurations.

4. 04Module 4 — Networks & Defensive Monitoring

   Understand what normal network activity looks like and learn how defenders monitor traffic, services, connections, and unusual behavior.

5. 05Module 5 — Logs: The Defender's Evidence

   Learn why logs are critical to cybersecurity investigations and how to collect, structure, search, and analyze them to understand what happened.

6. 06Module 6 — SIEM & Security Operations

   Discover how SIEM platforms bring security data together and learn how analysts use alerts, dashboards, queries, and correlation to identify potential incidents.

7. 07Module 7 — Detection Engineering

   Learn how security teams turn attacker behavior into detection rules and alerts. Explore the importance of reducing false positives while maintaining effective coverage.

8. 08Module 8 — Threat Intelligence

   Understand how defenders use threat intelligence to learn about adversaries, indicators, tactics, techniques, and emerging threats.

9. 09Module 9 — Endpoint Security

   Explore how defenders monitor workstations and servers for suspicious processes, files, connections, authentication activity, and other signs of compromise.

10. 10Module 10 — Incident Response

    Learn the incident-response lifecycle: preparation, identification, containment, eradication, recovery, and lessons learned.

11. 11Module 11 — Digital Forensics Fundamentals

    Discover the basics of investigating compromised systems and preserving evidence. Learn how artifacts such as logs, processes, files, and authentication records can help reconstruct an incident.

12. 12Module 12 — Threat Hunting

    Move beyond waiting for alerts. Learn how defenders proactively search for suspicious activity and investigate hypotheses based on attacker behavior.

13. 13Module 13 — Malware Analysis for Defenders

    Learn how defenders recognize suspicious files and understand basic malware behavior, indicators, and defensive response strategies in safe, isolated environments.

14. 14Module 14 — Attack Simulation & Defense

    Analyze controlled attack scenarios from the defender's perspective. Identify attacker activity, investigate evidence, contain the threat, and improve detection afterward.

15. 15Module 15 — Security Operations & Reporting

    Learn how professional SOC teams document incidents, communicate findings, prioritize alerts, escalate events, and produce clear security reports.

16. 16Final Blue Team Challenge

    Take part in a realistic simulated security incident. Monitor the environment, investigate alerts, identify the attack path, contain the threat, document your findings, and recommend improvements to the organization's defenses.
