Cloud Service Security Models: Navigating the Layers of Cyber Protection in the Cloud Era
Welcome to a comprehensive exploration of cloud service security models. This lesson is part of our “Basics in Cybersecurity Series”, delving into the intricacies of cloud computing and its critical security aspects.
Demystifying the Cloud
The cloud, often perceived as complex, is fundamentally a transformative approach to utilizing computing resources. It evolved from traditional setups where organizations owned extensive hardware systems.
The Birth of Cloud Computing
With virtualization technology, the underutilization of servers was addressed. This breakthrough led to cloud computing’s birth, characterized by its primary service models:
- Infrastructure as a Service (IaaS): Services like Amazon Web Services and Microsoft Azure offer fundamental computing resources.
- Platform as a Service (PaaS): Provides additional layers over IaaS, including operating systems and middleware.
- Software as a Service (SaaS): Examples include Google Mail and Salesforce, where software is hosted by a third party.
The Cloud Security Conundrum
In cloud environments, security is a shared responsibility between the cloud provider and the customer.
Shared Responsibility Model
- Physical Security: Provided by the cloud provider.
- Infrastructure Security: The provider secures the physical servers and virtualization layers.
- Application Security: The customer is responsible for securing their applications and data.
Challenges in Cloud Security
Transitioning to cloud services brings forth challenges, including basic security tools provided by cloud vendors and the complexity of securing multi-cloud environments.
