A hands-on roadmap for cyber security professionals — from securing and hardening systems to running penetration tests, hunting threats, responding to incidents, and operating the tools used on real targets every day.
Security work is heavily Linux and command-line driven. You will need these before the hands-on sections become practical.
A reference to follow when implementing a real network project.
Cyber Security engineering is the high-stakes discipline of protecting critical software applications, network infrastructure, and enterprise data from malicious threats and unauthorized exploitation. Security engineers combine defensive vigilance with offensive insight to safeguard systems.
This roadmap covers the complete cyber security spectrum: network packet inspection, system hardening, web application penetration testing (OWASP Top 10), threat hunting with SIEM and Sigma rules, digital forensics and incident response (DFIR), applied cryptography, and Zero Trust architecture.
Master TCP/IP network analysis with Wireshark, Linux/Windows OS hardening, log triage in SIEM platforms, and fundamental OWASP Top 10 vulnerabilities.
Key competencies:
Conduct web app pentesting with Burp Suite, author Sigma threat detection rules, investigate malware indicators (DFIR), and manage public key infrastructure (PKI).
Key competencies:
Architect Zero Trust enterprise perimeters, lead adversary emulation aligned with MITRE ATT&CK, manage cloud security (CSPM), and oversee SOC2/ISO audits.
Key competencies:
Starting with defensive security (SOC Analyst, System Hardening, Network Monitoring) builds an invaluable foundation in how systems, protocols, and logs actually work. Once you understand normal system behavior, identifying and testing vulnerabilities becomes significantly easier.
MITRE ATT&CK is a globally accessible knowledge base of adversary tactics, techniques, and procedures (TTPs) based on real-world cyber attacks. It provides a shared taxonomy for threat hunting, penetration testing, and evaluating security control coverage.
For entry-level roles, CompTIA Security+ provides a solid baseline. For penetration testing, the OSCP (Offensive Security Certified Professional) is the industry gold standard for hands-on capability. For experienced security management and architecture, the CISSP remains premier.
Document your practical labs on GitHub or a technical blog: publish write-ups of retired HackTheBox machines, create custom Sigma detection rules for recent CVEs, build open-source Python security tools, or participate in responsible vulnerability disclosure (Bug Bounty) programs.
