Which AWS service provides options for managing and securing encryption keys?

AWS Key Management Service (KMS) is the correct answer because it is specifically designed to create, manage, and control the use of encryption keys used to encrypt data across a variety of AWS services and applications. KMS provides a centralized key management mechanism that allows users to handle cryptographic keys in a secure and efficient manner. This service supports symmetric and asymmetric key generations and includes detailed logging of key usage and activity, which aids in compliance and auditing processes.

KMS integrates with many other AWS services, enabling seamless encryption solutions for data at rest and in transit. This feature is crucial for maintaining data privacy and securing sensitive information. Additionally, KMS can work alongside AWS Identity and Access Management (IAM) to provide fine-grained permissions for key usage, ensuring that only authorized users and applications can access the keys.

In summary, AWS KMS is the go-to service for managing and securing encryption keys in the AWS ecosystem, providing essential functionalities that help organizations meet regulatory compliance and secure their data effectively.
