If you want to build a career in cybersecurity, this roadmap will guide you from beginner to expert, covering skills, certifications, tools, and specializations. Whether your goal is to become a Penetration Tester, SOC Analyst, or Cybersecurity Engineer, this path will help you get there.
Phase 1: Foundation (Beginner Level)
Goal: Build strong computer and networking fundamentals.
Before diving into cybersecurity, you must understand how computers and networks work.
Learn the Basics
- Computer fundamentals: OS, file systems, CPU, RAM, storage
- Internet basics: IP, DNS, HTTP/HTTPS
- How data travels through networks (packets, ports, protocols)
Core Topics
- Networking: OSI model, TCP/IP, routing, switching
- Operating Systems: Windows + Linux basics
- Command-line tools: cmd, PowerShell, bash
- Virtualization: VirtualBox, VMware for lab setup
Practical Steps
- Install Linux (Ubuntu or Kali) on a VM
- Explore file systems, permissions, and terminal commands
- Learn basic network setup (LAN, IP config, DNS)
Recommended Learning
- Course: CompTIA IT Fundamentals (ITF+)
- Practice: Create a home lab using VirtualBox and Kali Linux
- Books: “Networking Basics for Hackers” or “The Linux Command Line”
Phase 2: Networking & System Administration
Goal: Master the systems and networks you’ll protect.
Cybersecurity experts must understand how systems and networks operate internally.
Networking Deep Dive
- TCP/IP model, IP addressing, Subnetting
- Firewalls, NAT, VPNs, VLANs
- Network devices: routers, switches, IDS/IPS
- Common ports and protocols (FTP, SSH, SMTP, HTTPS)
System Administration
- Windows Server: Active Directory, Group Policy, User Management
- Linux Administration: Shell scripting, cron jobs, SSH
- File permissions, process monitoring, system logs
Practical Steps
- Set up a local network in VirtualBox
- Create users, configure permissions
- Practice managing Linux/Windows servers
Recommended Learning
- CompTIA Network+
- Cisco CCNA (optional but highly valued)
- Free resources: Professor Messer Network+ playlist, NetworkChuck YouTube channel
Phase 3: Cybersecurity Fundamentals
Goal: Understand security concepts, threats, and vulnerabilities.
Once you know how networks and systems work, it’s time to learn how they can be attacked and protected.
Core Concepts
- CIA Triad (Confidentiality, Integrity, Availability)
- Threats: malware, phishing, ransomware, insider attacks
- Vulnerabilities, exploits, and patches
- Cryptography basics — encryption, hashing, keys, certificates
Tools to Learn
- Wireshark: Network traffic analysis
- Nmap: Network scanning
- Metasploit: Exploitation framework
- Burp Suite: Web app security testing
- Nessus / OpenVAS: Vulnerability scanning
Practical Steps
- Analyze packets with Wireshark
- Scan your home network with Nmap
- Try scanning vulnerabilities in test VMs
Recommended Learning
- CompTIA Security+ — solid cybersecurity foundation
- Practice labs on TryHackMe or Hack The Box
- Study OWASP Top 10 Web Vulnerabilities
Phase 4: Hands-On Ethical Hacking (Red Team)
Goal: Learn offensive hacking to strengthen your defense.
Ethical hacking teaches you how attackers think and act — which helps you defend better.
Key Concepts
- Footprinting & reconnaissance
- Scanning & enumeration
- Exploitation techniques
- Privilege escalation
- Web app attacks (SQLi, XSS, CSRF, SSRF)
- Wireless and password attacks
Tools
- Kali Linux (main hacking OS)
- Burp Suite
- Hydra / John the Ripper (password cracking)
- Aircrack-ng (Wi-Fi hacking)
- OWASP ZAP
Practical Steps
- Perform ethical hacking labs (TryHackMe “Complete Beginner to Expert”)
- Test vulnerabilities on demo sites (PortSwigger Web Security Academy)
- Participate in Capture the Flag (CTF) competitions
Recommended Learning
- EC-Council CEH (Certified Ethical Hacker)
- Practical Ethical Hacking course by Heath Adams (Udemy)
- Bug Bounty Hunting programs on HackerOne / Bugcrowd
Phase 5: Defensive Security (Blue Team)
Goal: Learn how to detect, respond, and prevent attacks.
Once you know how attacks happen, learn how to defend systems and analyze incidents.
Core Topics
- Incident Response: Detection → Containment → Eradication → Recovery
- Threat Intelligence: Identifying indicators of compromise (IOCs)
- SIEM Tools: Splunk, ELK Stack, IBM QRadar
- Digital Forensics: Collecting and analyzing evidence
- Malware Analysis: Reverse-engineering malicious code
Practical Steps
- Set up a free Splunk lab and analyze logs
- Simulate attacks using Metasploit and detect with SIEM
- Try malware sandbox tools like Any.Run
Recommended Certifications
- CompTIA CySA+ (Cybersecurity Analyst)
- Blue Team Level 1 (BTL1)
- GIAC GCIA / GCIH (Advanced defensive certs)
Phase 6: Advanced & Specialization
Goal: Pick your cybersecurity domain and master it.
After building a solid base, focus on one or two specialties to stand out.
Specialization Options
| Specialization | Description | Example Tools / Certs |
| Penetration Testing | Exploit systems & apps ethically | OSCP, Burp, Metasploit |
| SOC Operations | Monitor and respond to live threats | Splunk, CySA+, BTL1 |
| Digital Forensics (DFIR) | Investigate cybercrimes | Autopsy, EnCase, GCFA |
| Cloud Security | Secure AWS, Azure, GCP | AWS Security, CCSP |
| Application Security | Secure code & prevent vulnerabilities | OWASP, SANS DEV401 |
| Network Security Architecture | Design secure network frameworks | CISSP, CCNP Security |
Advanced Certifications
- OSCP (Offensive Security Certified Professional)
- CISSP (Certified Information Systems Security Professional)
- AWS / Azure Cloud Security Specialty
- GIAC series (for deep specialization)
Phase 7: Continuous Learning & Career Growth
Goal: Stay updated and grow your cybersecurity presence.
Cybersecurity evolves daily — continuous learning is key.
Keep Practicing
- Regularly use TryHackMe, Hack The Box, PortSwigger Academy
- Read threat reports from IBM, CrowdStrike, and CISA
- Follow top researchers on LinkedIn, X, and YouTube
- Participate in bug bounty and CTF competitions
