Determine maintenance tasks and processes. Account for the AWS shared responsibility model for database services The AWS shared responsibility model defines the division of security and compliance responsibilities between AWS and the customer. When it comes to database services, such as Amazon RDS (Relational Database Service) and Amazon DynamoDB, the shared responsibility model applies as follows: AWS Responsibilities: Infrastructure Security: AWS is responsible for securing the underlying infrastructure that supports the database services, including physical security, network security, and availability of data centers. Database Service Availability: AWS ensures that the database services are available and accessible to customers within the defined service level agreements (SLAs). Patching and Upgrades: AWS manages the patching and updates of the database service software, ensuring that the underlying infrastructure and database engine are up to date with security fixes. Customer Responsibilities: Data Protection: Customers are responsible for protecting their own data within the database services. This includes data encryption, access control, and implementing security measures to prevent unauthorized access. Configuration and Management: Customers are responsible for configuring and managing the database instances, including setting up security groups, managing database users and permissions, and implementing backup and recovery processes. Application-Level Security: Customers are responsible for securing their applications that interact with the database services, including implementing secure coding practices, preventing injection attacks, and managing authentication and authorization mechanisms. Compliance and Auditing: Customers are responsible for meeting regulatory and compliance requirements applicable to their data, including data privacy, industry-specific regulations, and data retention policies. It's important to note that while AWS takes care of the underlying infrastructure and the security of the database services, customers still have significant responsibilities for securing their data, applications, and configurations within those services. Following security best practices, implementing appropriate access controls, encrypting sensitive data, and regularly reviewing and updating security measures are essential for fulfilling the customer's responsibilities under the shared responsibility model. AWS provides various security tools, features, and services that customers can leverage to enhance their security posture within the AWS environment. It's recommended to review the specific documentation and guidelines provided by AWS for each database service to ensure compliance with the shared responsibility model and to implement appropriate security measures for your specific use case.
