in simple and easy language, with definitions, diagrams, examples, threats, solutions, and key exam points.
Cloud Security is the set of policies, technologies, tools, and controls used to protect cloud data, applications, and infrastructure from cyber threats and unauthorized access.
👉 In simple words: Protecting cloud data and systems from hackers and misuse
Cloud security ensures:
✔ Protects sensitive data ✔ Prevents hacking and data theft ✔ Ensures privacy ✔ Maintains system availability ✔ Builds user trust
User → Authentication → Authorization → Secure Cloud Access → Data Protection
Protecting data stored in cloud
✔ Methods:
Protecting cloud networks from attacks
✔ Methods:
Securing cloud applications
✔ Example:
Controlling who can access what
✔ Methods:
Protecting cloud data centers
✔ Example:
Converting data into unreadable form
✔ Protects data during storage and transfer
Verifying user identity
✔ Example:
✔ Uses:
Filters incoming and outgoing traffic
Restoring lost data
Detects suspicious activity
Limits user permissions
