4. Cloud Security
Cloud security protects data stored on online platforms and cloud services.
5. Endpoint Security
Endpoint security protects devices like laptops, smartphones, and tablets from cyber threats.
6. Identity and Access Management (IAM)
This ensures that only authorized users can access specific systems and data.
Common Cyber Security Threats
Understanding cyber threats is essential to staying safe. Here are the most common threats:
