Cyber Security Roadmap
A beginner-to-job-ready roadmap covering networking fundamentals, defensive security, ethical hacking, and professional certifications to launch a cyber security career.
✓ Every resource link below is verified live.
1. Stage 1: Foundations & Core Concepts
Networking Fundamentals
All security concepts rely on understanding how networks communicate.
Operating Systems (Linux & Windows)
Security professionals must administer and harden both OS families.
Core Security Concepts (CIA Triad, Threats, Vulnerabilities)
Foundational vocabulary underpins every cyber security discipline.
Introduction to Cryptography
Encryption and hashing protect data at rest and in transit.
2. Stage 2: Networking & Protocol Deep Dive
TCP/IP, DNS, HTTP/S & Common Protocols
Attackers exploit protocol weaknesses; defenders must know them deeply.
Packet Analysis with Wireshark
Capturing and reading packets reveals malicious traffic patterns.
Firewalls, IDS/IPS & VPNs
These are primary perimeter controls in every enterprise environment.
Network Scanning & Enumeration (Nmap)
Knowing what's on a network is step one for both attackers and defenders.
3. Stage 3: Defensive Security & Blue Team Skills
Security Information & Event Management (SIEM)
SIEMs aggregate logs for detecting and investigating incidents at scale.
Incident Response & Handling
Structured response limits damage and recovery time after breaches.
Vulnerability Management & Scanning
Proactively finding weaknesses before attackers do reduces attack surface.
Hardening & Security Baselines
Reducing default configurations limits exploitable attack vectors.
4. Stage 4: Ethical Hacking & Offensive Techniques
Web Application Security (OWASP Top 10)
Web apps are the most attacked surface; OWASP Top 10 is the baseline.
Penetration Testing Methodology
A structured methodology ensures thorough and legal security assessments.
Exploitation Basics with Metasploit
Metasploit is the industry-standard framework for understanding exploits.
Password Attacks & Privilege Escalation
Credential attacks are the leading initial access technique in breaches.
5. Stage 5: Cloud & Application Security
Cloud Security Fundamentals (AWS/Azure/GCP)
Most enterprises run workloads in cloud; cloud misconfigs cause major breaches.
Secure Software Development (DevSecOps)
Shifting security left into the SDLC prevents vulnerabilities at the source.
Container & Kubernetes Security
Containerized workloads introduce unique runtime and supply-chain risks.
6. Stage 6: Governance, Risk & Compliance (GRC)
Risk Management Frameworks (NIST CSF, ISO 27001)
Security programs must align with business risk and regulatory requirements.
Compliance & Regulations (GDPR, HIPAA, PCI-DSS)
Non-compliance carries legal penalties and reputational damage.
Security Policies & Documentation
Written policies enforce accountability and guide employee security behavior.
7. Stage 7: Certifications, CTFs & Career Launch
Industry Certifications (CompTIA Security+, CEH, OSCP)
Certifications validate skills and are often required for security job roles.
Capture the Flag (CTF) Practice
CTFs build hands-on attacker mindset and problem-solving under pressure.
Building a Home Lab
Practical lab experience accelerates skill development beyond courses alone.
Portfolio, Resume & Job Search
Showcasing projects and skills differentiates candidates in a competitive market.
