How to Start a Career in Cybersecurity in Nigeria

Cybersecurity is not one job, it is a family of roles with different skills, different entry points, and different timelines. Here is a realistic map of where to start, what to learn first, and which certifications are actually worth the money.

01It Is Not One Job

"I want to get into cybersecurity" is a bit like saying "I want to get into medicine." True, but which part? Defending networks, breaking into systems on purpose to find holes before criminals do, investigating incidents after they happen, and writing the policies that govern all of it are genuinely different jobs with different daily work, even though they all fall under one umbrella term.

02The Main Entry-Level Roles

SOC AnalystMonitors security alerts in real time, the most common entry point into a security team, and where most people actually start.
Penetration TesterBreaks into systems with permission, to find the holes before a real attacker does. Usually not a day-one entry role; most testers start in a SOC or as a developer first.
Security EngineerBuilds and maintains the actual defenses: firewalls, access controls, secure infrastructure. Often a path from general software or systems engineering.
Incident Responder / ForensicsInvestigates what happened after a breach, reconstructs the timeline, and helps prevent a repeat.

03Foundations to Build First

Before any specialization, three foundations matter more than any tool or certification: how networks actually work (TCP/IP, DNS, how traffic moves), how operating systems work (Linux fundamentals especially, since most security tooling lives there), and basic scripting (Python or Bash, enough to automate a repetitive task). Skip these and every certification you chase afterward is memorized theory without the intuition to apply it.

04Certifications Worth Pursuing

The industry has a lot of certifications, and not all of them are worth the money at every stage. As a realistic order: CompTIA Security+ is the most recognized entry-level credential and a genuinely reasonable first target. CEH (Certified Ethical Hacker) is well-known and useful for signaling intent toward offensive security, though employers increasingly weight practical skill over the certificate alone. OSCP (Offensive Security Certified Professional) is the one that actually carries weight for a penetration testing role, because it's a hands-on practical exam, not multiple choice, but it's a stretch goal, not a starting point.

05The Nigerian Angle

Nigerian banks, fintechs, and telcos all run real internal security teams, and demand for people who genuinely understand both offense and defense keeps growing as digital fraud gets more sophisticated. The threats covered in TEKHUB's own case-file series, phishing, SIM-swap-style takeovers, BVN scams, are not abstract international examples; they're the exact fraud patterns a Nigerian security analyst deals with in real incident response.
