Cybersecurity has become one of the most valuable and practical skills in Nigeria today. As more Nigerians rely on smartphones, online banking, digital businesses, remote jobs, and social media, cybercrime has increased rapidly. From online scams and identity theft to hacked websites and stolen business data, digital threats are now part of everyday life.

What Cybersecurity Really Means (Explained Simply)
Cybersecurity is the practice of protecting digital systems from attacks. These systems include computers, phones, websites, networks, servers, and online accounts.
In simple terms, cybersecurity answers questions like:
How do hackers break into systems?
How do we prevent them?
What do we do when an attack happens?
How do we keep data safe?
Cybersecurity is not just about hacking. Many beginners combine cybersecurity with other tech skills to increase opportunities, just like those learning data, marketing, or design skills outlined in Digital Skills for the Future. It also includes:
Securing passwords and accounts
Protecting company networks
Detecting suspicious activities
Responding to cyber incidents
Educating users on safe online behaviour
In Nigeria, cybersecurity is used in:
Banks and fintech companies
Telecoms and internet providers
Government systems
Schools and universities
Hospitals and healthcare systems
Online businesses and startups
