Answer: AWS Key Management Service (KMS) is a fully managed service from Amazon Web Services (AWS) that allows you to create and manage encryption keys used to encrypt data. Encryption keys are easy to manage and help you protect data stored in AWS services and applications.
Q2. What are AWS KMS keys?
Answer: AWS KMS key is the logical representation of an encryption key in AWS KMS. It is used to encrypt and decrypt data stored in various AWS services such as Amazon S3, Amazon RDS, and Amazon EBS. KMS keys provide secure storage, access control and auditing.
Answer: AWS KMS uses a process called key generation to generate encryption keys. In the AWS KMS service, sensitive information is securely created and cannot be accessed by the user. The key file is used to encrypt and decrypt data, and the key itself is used for the key file.
Q4. What are AWS KMS keys?
Answer: AWS KMS supports two types of customer master keys (CMKs):
- AWS-managed CMKs: These keys are created, managed, and rotated by AWS on your behalf. It is designed for simplicity and ease of use.
- Customer Control CMKs: These keys are created and managed by you so you have full control over your key loop, including rotation and deletion.
Q5. How does AWS KMS secure keys?
Answer: AWS KMS uses a variety of security measures to protect the confidentiality and integrity of keys. Important information is never left out of the AWS KMS service. AWS KMS also integrates with AWS Identity and Access Management (IAM) to manage access to keys based on privileges and user roles.
Q6. What is AWS KMS?
Answer: Key rotation is the process of automatically generating new encryption keys and deprecating old ones. AWS KMS supports key changes for customer-managed CMKs that help improve the security of encrypted data without changing the keys in your application.
Q7. Can AWS KMS keys be used outside of AWS services?
Answer: Yes, AWS KMS keys can be used outside of AWS services. AWS KMS provides APIs that allow you to integrate KMS keys into your own applications and services, providing a valuable solution for your data.
Q8. What is Envelope Encryption and AWS KMS?
Answer: Encryption envelope is a process that encrypts data with data key and then encrypts data key with master key.
AWS KMS is a service that provides the master key used for the encryption envelope. AWS KMS simplifies the management and protection of master keys, making it easier to implement secure encryption methods.
Q9. How does AWS KMS integrate with AWS CloudTrail?
Answer: AWS KMS integrates with AWS CloudTrail to provide auditability and visibility into key usage.
CloudTrail lists key administrative events such as creation, deletion, and usage, allowing you to track and monitor key events for compliance and security purposes.
Q10. How does AWS KMS support compliance and data protection?
Answer: AWS KMS helps with compliance and data protection by providing centralized key management, insights, and access control. It allows you to securely and efficiently manage encryption keys, helping you meet regulatory and data privacy requirements.
