"2023最新AWS认证开发者实践真题及答案：加密存储访问令牌解决方案"

e developer decides to store the access token in an AWS Systems Manager Parameter Store. The parameter store allows for secure storage of sensitive information such as passwords, API keys, and access tokens. The developer can use AWS Key Management Service (KMS) to encrypt the parameter store values, ensuring that the access token is encrypted at rest. To ensure that the access token is encrypted in transit, the developer can use AWS Identity and Access Management (IAM) roles to control access to the parameter store and restrict permissions to only the necessary actions. By using IAM roles, the developer can grant the application the necessary permissions to retrieve the access token from the parameter store without exposing it to unauthorized users. Additionally, the developer can use AWS Secrets Manager to rotate the access token periodically to enhance security. By configuring rotation policies in Secrets Manager, the access token can be automatically updated without manual intervention, reducing the risk of unauthorized access due to compromised tokens. For further information on securely storing sensitive information in AWS, the developer can refer to the official AWS documentation on AWS Systems Manager Parameter Store, AWS Key Management Service, and AWS Secrets Manager. These resources provide detailed guidelines on best practices for encryption and access control in AWS environments, ensuring the confidentiality and integrity of sensitive data. In conclusion, by storing the access token in an encrypted parameter store, using IAM roles for access control, and implementing token rotation with Secrets Manager, the developer can securely store and manage sensitive information in AWS while ensuring the confidentiality and integrity of the data. This approach aligns with industry best practices for protecting data and mitigating security risks in cloud-based applications.
