    AWS Shared Responsibility Model

    A framework that outlines how security responsibilities are divided between AWS and its customers.

    AWS Responsibilities (Security of the Cloud)

    Physical Security: secures data centres (e.g., guards, cameras, controlled access).

    Hardware Management: AWS maintains and updates servers, storage devices, and networking equipment.

    Global Infrastructure: AWS ensures the security and availability of regions, availability zones, and edge locations.

    Managed Services Security: For managed services like Amazon RDS (Relational Database Service), AWS handles tasks like operating system updates and patching.

    Shared Responsibilities

    Patch Management: AWS patches the infrastructure, but you must patch your applications if you’re using services like EC2.

    Data Encryption: AWS offers encryption tools, but you decide what data to encrypt and manage encryption keys.

    How Responsibilities Shift Based on Service

    depending on whether you’re using Infrastructure as a Service (IaaS), Platform as a Service (PaaS), or Software as a Service (SaaS)

    Define the security responsibility when using Amazon EC2 (IaaS - Infrastructure as a Service).

    AWS: Manages physical infrastructure (data centers, servers, storage).

    Customer: operating system upwards, including applications, Configures network firewalls (security groups). Encrypts data stored on volumes.

    Define the security responsibility when using Amazon RDS (Relational Database Service) (PaaS -Platform as a Service)

    AWS: Handles infrastructure, operating system. Manages the underlying database engine. Handles patches and updates for the database software.

    Customer: Manages data (Ensures data is secure (e.g., encrypting sensitive fields).) Manages database access (users, passwords). application-level security. (database queries - database credentials)

    Define the security responsibility when using AWS Lambda (SaaS - Software as a Service)

    AWS: Manages infrastructure, operating systems, runtime environment.

    Customer: Ensures the function code is secure and performs intended tasks securely. Configures triggers securely (e.g., event sources like S3 or API Gateway). data provided to the service.

    Customer Responsibilities (Security in the Cloud) with examples

    Data: Protecting sensitive data stored in AWS. Example: Encrypting customer data stored in Amazon S3 using AWS Key Management Service (KMS).

    Applications: Securing applications running in the cloud. Example: Applying security patches to an application hosted on an Amazon EC2 instance.

    User Access Management: Managing who can access your AWS environment. Example: Creating IAM roles to restrict access to an Amazon RDS database.

    Configuration: Ensuring services like Amazon EC2 (Elastic Compute Cloud) are configured securely. Example: Configuring Security Groups in Amazon EC2 to allow only HTTPS traffic (port 443).

    Responsibilities Role-Based Access Level

    AWS allows the creation of roles using IAM, but you must define and assign roles to users or applications to restrict access based on their responsibilities.

    Study Notes

    AWS Shared Responsibility Model

    • A framework defining security responsibilities between AWS and customers.
    • AWS Responsibility: Securing the cloud infrastructure (physical security, hardware management, global infrastructure, managed service security).
    • Customer Responsibility: Securing resources within the cloud (data, applications, user access management, configuration).

    Key Concepts

    • AWS Responsibility (Cloud Security):
      • Physical security: data centers (guards, cameras, access control).
      • Hardware management: servers, storage, networking maintenance and updates.
      • Global infrastructure: regions, availability zones, edge locations.
      • Managed service security: services like Amazon RDS (operatingsystem updates, patching).
    • Customer Responsibility (In-cloud Security):
      • Data protection: sensitive data stored in AWS.
      • Application security: securing applications in the cloud.
      • User access management: controlling AWS environment access (IAM roles, policies).
      • Configuration security: secure service configurations (e.g., firewall rules, encryption for Amazon EC2).

    Shared Responsibilities

    • Patch Management: AWS patches infrastructure; Customers patch applications (e.g., EC2).
    • Data Encryption: AWS offers tools; Customers decide what to encrypt and manage keys.

    Responsibilities by Service Type

    • Infrastructure as a Service (IaaS) - Example: Amazon EC2:
      • AWS: Manages physical infrastructure (data centers, servers, storage).
      • Customer: Manages everything above the infrastructure (operating system, applications, data, user access).
    • Platform as a Service (PaaS) - Example: Amazon RDS:
      • AWS: Manages infrastructure, OS, and database engine.
      • Customer: Manages data, database access, and application-level security.
    • Software as a Service (SaaS) - Example: AWS Lambda:
      • AWS: Manages everything (infrastructure, OS, runtime environment).
      • Customer: Focuses on code and data security provided to the service.

    Responsibilities by Example

    • Amazon EC2 (IaaS):
      • AWS: Secures physical servers, networking, hypervisors.
      • Customer: Installs, secures OS, configures security groups, encrypts data volumes.
    • Amazon RDS (PaaS):
      • AWS: Manages database engine, handles patches and updates.
      • Customer: Manages database access, ensures data security (encryption).
    • AWS Lambda (SaaS):
      • AWS: Manages infrastructure, scaling, runtime environment.
      • Customer: Secures function code, configures triggers securely (e.g., S3, API Gateway).

    Importance of the Model

    • Secure Environment: Clear understanding of responsibilities.
    • Prevent Security Breaches: Avoid omissions and ensure comprehensive security measures.

    Study Tips

    • Memorize Responsibilities: Distinguish AWS and customer responsibilities.
    • Use Examples: Understand how responsibilities change with EC2, RDS, Lambda.
    • Understand Key Terms:
      • Encryption: Customers decide what to encrypt; AWS provides tools.
      • Firewalls (Security Groups): Customers configure for specific traffic.
      • Patching: AWS manages infrastructure; customers manage applications.
      • Backup and Recovery: AWS secures storage; customers configure data backups.
      • Data Responsibility: AWS secures infrastructure; customers secure data stored.
      • Configuration Management: AWS provides tools; customers define compliance.
      • Disaster Recovery (DR): Services provided by AWS; customers implement DR plans.
      • Role-Based Access (IAM): AWS provides tools; customers define user/application access.
    • Visualize: AWS as building owner; customer as tenant responsible for its space.
