Infrastructure Security in Cloud Computing

Infrastructure security in cloud computing ensures the safety of data, applications, and services hosted in the cloud. It involves measures like encryption, firewalls, identity and access management (IAM), and secure network configurations. Cloud providers and users share responsibilities for security under the "shared responsibility model." Providers secure physical infrastructure, while users manage data, applications, and access controls. Key threats include data breaches, insider threats, and DDoS attacks. Strategies like multi-factor authentication, regular security audits, and compliance with frameworks (e.g., ISO 27001) enhance protection. Organizations should adopt a zero-trust approach, ensuring strict verification for every user and device. Proactive monitoring, incident response plans, and continuous updates are essential to mitigate risks in cloud environments.

1. Infrastructure Security in Cloud Computing digitdefence.com
2. Introduction to Cloud Computing On-Demand Resources Users can access and scale computing resources like servers, storage, and databases as needed, eliminating the need for upfront investments. Pay-As-You-Go Users only pay for the resources they consume, reducing operational costs and maximizing efficiency. Global Reach Cloud providers offer services across multiple data centers, providing global accessibility and redundancy. digitdefence.com
3. Shared Responsibility Model in Cloud Security 1 Cloud Provider Responsible for the underlying infrastructure, network security, and platform security. 2 Customer Responsible for data security, application security, and user access management. digitdefence.com
4. Network Security in the Cloud Virtual Private Networks (VPNs) Create secure connections between users and cloud resources. Firewalls Filter incoming and outgoing traffic, blocking unauthorized access. Network Segmentation Divides the network into isolated segments to limit the impact of security breaches. digitdefence.com
5. Identity and Access Management Multi-Factor Authentication (MFA) Requires multiple forms of identification to verify user identity. Role-Based Access Control (RBAC) Grants users access to specific resources based on their roles and responsibilities. Least Privilege Principle Users should only have access to the resources they need to perform their tasks. digitdefence.com
6. Data Security and Encryption 1 Encryption at Rest Data is encrypted when stored on cloud storage services. 2 Encryption in Transit Data is encrypted during transmission between users and cloud resources. 3 Data Loss Prevention (DLP) Tools that identify and prevent the loss of sensitive data. digitdefence.com
7. Compliance and Regulatory Requirements HIPAA For healthcare organizations handling protected health information. PCI DSS For organizations handling credit card data. GDPR For organizations processing personal data of individuals in the European Union. digitdefence.com
8. Incident Response and Disaster Recovery 1 Incident Detection Identify potential security incidents through monitoring and logging. 2 Containment Isolate the affected systems to prevent further damage. 3 Recovery Restore affected systems and data to a secure state. digitdefence.com
9. Monitoring and Logging in the Cloud 24/7 Continuous Monitoring Monitor cloud resources and security events around the clock. 100% Log Analysis Analyze security logs to identify suspicious activities and potential threats. digitdefence.com
