To maintain data confidentiality, implement server-side encryption for data at rest in AWS storage and database services. Additionally, use AWS Key Management Service to store and manage your encryption keys securely. For data in transit, enable HTTPS (TLS) to ensure that your data is encrypted while being transmitted.

You can enhance the trustworthiness of your data and resources by using AWS Key Management Service (KMS) and AWS Certificate Manager (ACM) across all accounts in your organization. This approach provides broad security coverage and helps ensure that your data is protected and managed effectively.

To maintain control over your personal data, utilize tools like AWS Secrets Manager to protect database access credentials and AWS Private CA to manage certificates at scale. Additionally, consider using Amazon Macie to discover and classify sensitive data, which can help you meet privacy regulations and ensure compliance.
