Cybersecurity is the practice of protecting systems, networks, devices, and data from digital attacks, unauthorized access, damage, or theft. It involves using technologies, processes, and controls to ensure the confidentiality, integrity, and availability (CIA) of information.

🔐 Key Areas of Cybersecurity

1. Network Security – Protecting networks from intruders, malware, and attacks.
2. Application Security – Securing software and apps from vulnerabilities.
3. Information Security – Safeguarding data from unauthorized access or alteration.
4. Operational Security – Managing access controls and permissions.
5. Endpoint Security – Protecting devices like laptops and mobile phones.
6. Cloud Security – Securing cloud-based systems and data.
7. Identity and Access Management (IAM) – Ensuring only authorized users can access resources.
8. Disaster Recovery & Business Continuity – Ensuring systems can recover from attacks or failures.
