In today’s digital world, everything from your bank account to your medical records is online. That convenience also brings risks—cybercriminals are constantly finding new ways to exploit systems, steal data, and cause chaos. This is where cybersecurity comes in.
🧠 What is Cybersecurity?
Cybersecurity is the practice of protecting systems, networks, and data from digital attacks. These attacks are often aimed at accessing, changing, or destroying sensitive information, extorting money from users, or interrupting normal business operations.
