What is the Shared Responsibility Model in AWS

The Shared Responsibility Model is a fundamental concept in AWS that defines who is responsible for what when it comes to security and compliance in the cloud.

In this model, responsibilities are shared between AWS and the customer:

---

🔐 AWS's Responsibility – "Security of the Cloud"

AWS is responsible for the infrastructure that runs all the services offered in the AWS Cloud. This includes:

• Physical security of data centers

• Network infrastructure

• Hardware and software that support the cloud services

• Environmental controls (power, cooling, etc.)

---

🧑‍💻 Customer's Responsibility – "Security in the Cloud"

The customer is responsible for securing the data and applications they put into the cloud. This includes:

• Managing access using IAM (Identity and Access Management)

• Securing your data (e.g., encryption, backups)

• Updating your software and operating systems

• Configuring firewalls and network settings (e.g., security groups, NACLs)

---

🤝 Why is it Important?

Understanding this model helps avoid confusion. Many security issues happen because people think AWS handles everything. In reality, both AWS and the customer must work together to keep things secure.
