Cloud Security
Protecting data, applications, and infrastructure in cloud environments
Cloud security encompasses the technologies, policies, controls, and services that protect cloud data, applications, and infrastructure from threats. As organizations migrate to cloud environments, they face unique security challenges that require specialized approaches and shared responsibility between cloud service providers and customers.
Key Security Considerations
- • Data protection and privacy
- • Identity and access management
- • Compliance and governance
- • Threat detection and response
- • Business continuity and disaster recovery
Cloud Deployment Models
- • Public cloud (AWS, Azure, GCP)
- • Private cloud (dedicated infrastructure)
- • Hybrid cloud (combination of public/private)
- • Multi-cloud (multiple providers)
- • Community cloud (shared by specific community)
Shared Responsibility Model
Cloud security operates on a shared responsibility model, where the cloud provider and customer each have distinct security responsibilities depending on the service model:
Infrastructure as a Service (IaaS)
Provider secures physical infrastructure, network, and hypervisor. Customer responsible for OS, applications, data, and access management.
Platform as a Service (PaaS)
Provider secures infrastructure and platform components. Customer responsible for applications, data, and access management.
Software as a Service (SaaS)
Provider secures most components. Customer primarily responsible for data classification, user access management, and compliance.
Misconfiguration
Improperly configured cloud resources leading to exposure
Insecure APIs
Vulnerable interfaces for cloud service management
Identity Management
Weak authentication and authorization controls
Data Protection
Inadequate encryption and data loss prevention
Compliance
Meeting regulatory requirements across jurisdictions
