INFRASTRUCTURE SECURITY IN CLOUD COMPUTING

 INFRASTRUCTURE SECURITY

 Definition

Security of the IT environment, including hardware, networks, virtual machines, storage, and operating systems, whether on-premises or in the cloud, against threats such as unauthorized access, data breaches, or service disruptions.

 

 Features of Infrastructure Security

1. Comprehensive Protection: 

2. Scalability:

3. Automation: 

4. Shared Responsibility: 

5. Compliance Integration: 

6. Resilience(flexibility): 

 

 Types of Infrastructure Security

Categorized based on the components it protects:

 1. Physical Infrastructure Security:

   - Protects data centres, servers, and hardware.

 

2. Network Security:

   - Secures data transmission and network connectivity.

   

3. Compute Security:

   - Protects virtual machines (VMs), containers, and serverless functions.

   

4. Storage Security:

   - Safeguards data stored in cloud databases, object storage (e.g., AWS S3), or block storage.

    

5. Endpoint Security:

   - Secures devices (laptops, mobiles) accessing cloud infrastructure.

  

 Tools for Infrastructure Security

1. Cloud-Native Tools:

   - AWS: GuardDuty, Inspector, CloudTrail.

   - Microsoft Azure: Azure Defender, Azure Security Center.

   - Google Cloud: Security Command Center, Chronicle.

 

2. Third-Party Tools:

   - Palo Alto Prisma Cloud: 

   - CrowdStrike Falcon: 

   - Splunk: 

   - Tenable Nessus: 

 

3. Open-Source Tools:

   - Wazuh: 

   - Falco: 

 Techniques for Infrastructure Security

1. Encryption:

2. Identity and Access Management (IAM):

3. Network Segmentation:

4. Patch Management:

   - Regularly update.

 5. Threat Detection and Response:

   - Deploy Intrusion Detection/Prevention Systems (IDS/IPS) and SIEM solutions.

   - Example: Use AWS GuardDuty to detect malicious activity in real time.

 6. Configuration Management:

 7. Zero Trust Architecture:

 8. Backup and Disaster Recovery:

 

 Advantages of Infrastructure Security

1. Enhanced Protection: .

2. Compliance: .

3. Scalability: 

4. Automation: 

5. Resilience: 

6. Cost Efficiency: 

 

 Limitations of Infrastructure Security

1. Complexity:

2. Misconfiguration Risks:

 3. Cost:

 4. Shared Responsibility Confusion:

 5. Evolving Threats:

  6. Skill Gaps:
