  (Defend, Monitor, Respond)       (Attack, Exploit, Report)

Path A: Security Operations Center (SOC Analyst / Blue Team)

What You Do: You monitor security alerts. You investigate active incidents. You analyze system logs and defend the network from cyber attacks.

• Core Topics: SIEM, EDR, Threat Hunting, Incident Response Playbooks, Log Analysis, Sigma/YARA Rules, and Malware Analysis Basics.
• Primary Tools: Splunk, Microsoft Sentinel, Elastic Stack, Wazuh.
• Recommended Certifications:
• Cisco CyberOps Associate
• CompTIA CySA+
• BTL1 (Blue Team Level 1)

Path B: Penetration Tester / Ethical Hacker (Red Team)

What You Do: You act like a real attacker. You find security vulnerabilities. You safely exploit corporate systems and write detailed reports.

• Core Topics: Passive & Active Reconnaissance (OSINT), Port Scanning, Web Application Testing (OWASP Top 10), Active Directory Exploitation, Privilege Escalation, and Password Attacks.
• Primary Tools: Nmap, Burp Suite, Metasploit, Hydra, Hashcat, John the Ripper, ffuf.
• Recommended Certifications:
• eJPT (Junior Penetration Tester)
• CompTIA PenTest+
• OSCP (Offensive Security Certified Professional)

Phase 3: Advanced Career Paths

You will master the Blue Team or Red Team first. Then, you can choose an advanced career.

1. Purple Teaming

• What You Do: You mix defense and offense. You use Red Team attacks to test Blue Team alerts. You make the whole security team stronger.

2. DevSecOps

• What You Do: You add security to software development. You automate security testing for new code.

3. Cloud Security Engineer

• What You Do: You defend large cloud networks. You manage security for AWS, Azure, or Google Cloud.

4. Malware Analysis

• What You Do: You take apart harmful software. You learn exactly how viruses work. You use this knowledge to build better defenses.
