Cybersecurity is the practice of protecting computer systems, networks, data, and digital devices from unauthorized access, attacks, damage, or theft. It involves using technologies, processes, and strategies to safeguard information and ensure:
🔒 Confidentiality – keeping information private and only accessible to authorized people.
⚖️ Integrity – making sure data is accurate and not altered by unauthorized users.
📶 Availability – ensuring systems, applications, and data are accessible whenever needed.
Cybersecurity covers many areas such as:
Network Security (protecting networks from hackers or malware)
Information Security (keeping sensitive data safe)
Application Security (making sure apps are secure from vulnerabilities)
Cloud Security (protecting data stored online)
Endpoint Security (securing laptops, phones, and other devices)
👉 In short, cybersecurity is all about defending digital systems from cyber threats like hacking, phishing, viruses, and ransomware.
