INTRODUCTION OF CLOUD SECURITY

Refers to the set of policies, technologies, and practices designed to protect data, applications, and infrastructure hosted in cloud environments from threats, unauthorized access, and data breaches.

 Key Components of Cloud Security

1. Data Security:

   - Encryption: 

   - Data Loss Prevention (DLP): 

   - Backup and Recovery:  

2. Identity and Access Management (IAM):

   - Authentication: 

   - Authorization: 

   - Single Sign-On (SSO):  

3. Network Security:

   - Firewalls: 

   - Virtual Private Cloud (VPC):

   - DDoS Protection:  

4. Application Security:

   - Secure Development Practices: 

   - Web Application Firewalls (WAF): 

   - API Security: 

 5. Endpoint Security:

   - Protects devices (laptops, mobiles, etc.)

   

6. Monitoring and Threat Detection:

   - Security Information and Event Management (SIEM):

   - Intrusion Detection and Prevention Systems (IDPS):

   - Cloud-Native Monitoring Tools:

 7. Compliance and Governance:

   - Ensures adherence to regulations 

   - Implements policies .

   - Regular security assessments.

 

8. Shared Responsibility Model

Cloud security operates under a shared responsibility model, where responsibilities are divided between the cloud service provider (CSP) and the customer:

- Cloud Provider Responsibilities:

 - Customer Responsibilities:

The exact division depends on the cloud service model:

- IaaS

- PaaS

- SaaS 

 

 Common Cloud Security Challenges

1. Misconfigurations: 

2. Insider Threats: 

3. Advanced Persistent Threats (APTs):

4. Shadow IT: 

5. Multi-Cloud Complexity: 

 

  Emerging Trends in Cloud Security

- AI and Machine Learning: 

- Cloud-Native Security: 

- Confidential Computing: 

- Serverless Security: 

- Zero Trust Architecture:
