The digital world keeps evolving, and with it comes a growing demand for experts who can secure data and systems from complex threats. While cybersecurity  and information security may sound alike, they differ in scope, skills, and salary potential. In 2025, both fields are booming, especially in Nigeria, where digital transformation is accelerating. If you’re considering a career in tech, understanding these differences will help you make the right choice—and with training from ECR Academy, you can get started without breaking the bank.

Cybersecurity vs. Information Security: What’s the Difference?

Cybersecurity focuses on protecting digital systems, networks, and online assets from hackers, malware, and other cyber threats. It’s the frontline defense against attacks. Information security (InfoSec) is broader; it covers all forms of information, whether digital, physical, or even verbal. Think of it this way: all cybersecurity is information security, but not all information security is cybersecurity.

Overlapping Areas Between the Two Fields

Both aim to protect sensitive information, but cybersecurity is a subset of information security. Think of it like this: all cybersecurity is information security, but not all information security is cybersecurity.
