Cloud security includes a set of policies, technologies, and controls designed to protect:

• Data stored in the cloud

• Applications running in the cloud

• Infrastructure that supports cloud computing

☁️ Types of Cloud Environments:

1. Public Cloud – Services offered over the internet by providers like AWS, Azure, or Google Cloud.

2. Private Cloud – Cloud environment used exclusively by one organization.

3. Hybrid Cloud – Combination of public and private clouds.

4. Multi-Cloud – Using multiple cloud providers for different services.

🔑 Key Cloud Security Challenges:

• Data breaches and leaks

• Misconfigured cloud settings

• Unauthorized access

• Insecure APIs

• Insider threats

• Compliance with regulations (like GDPR, HIPAA, etc.)

🛡️ Cloud Security Measures:

1. Identity and Access Management (IAM) – Controls who can access what.

2. Encryption – Protects data at rest and in transit.

3. Firewalls & Intrusion Detection Systems (IDS/IPS) – Monitor and control network traffic.

4. Endpoint Security – Protects devices connected to the cloud.

5. Regular Auditing & Monitoring – Ensures systems remain secure.

6. Zero Trust Security Model – “Never trust, always verify” approach.

7. Backup and Disaster Recovery – Ensures data can be restored after incidents.
