The AWS Shared Responsibility Model is a crucial concept for understanding security and compliance in the Amazon Web Services (AWS) cloud. It clarifies the division of security responsibilities between AWS and its customers. Here's a breakdown:
AWS Training in Pune Core Concept:
Essentially, AWS is responsible for the "security of the cloud," while the customer is responsible for "security in the cloud."
AWS Responsibilities ("Security of the Cloud"):
AWS is responsible for protecting the infrastructure that runs all of the AWS services. This includes:
Physical security of data centers.
Hardware and software infrastructure.
Networking components.
Customer Responsibilities ("Security in the Cloud"):
Customer responsibilities vary depending on the AWS services they use. Generally, customers are responsible for:
Managing their data.
Controlling access to their resources.
Configuring security settings.
Operating system security (in some cases).
Application security.
Variations Based on Service Type:
The degree of customer responsibility changes based on the type of AWS service used.
Infrastructure as a Service (IaaS) (e.g., EC2): Customers have more responsibility, as they manage the operating system, applications, and data.
Platform as a Service (PaaS) (e.g., RDS): AWS manages the underlying infrastructure, and customers focus on application and data security.
Software as a Service (SaaS) (e.g., S3): AWS manages most of the infrastructure, and customers primarily focus on data security and access control.
Key Takeaways:
Understanding the Shared Responsibility Model is essential for maintaining a secure AWS environment.
Customers must actively manage their security responsibilities to protect their data and applications.
It is very important to remember that regardless of the type of cloud service being utilized, that the customer is always responsible for their data.
