Data Security
Encryption: As a best practice to secure your data in AWS, encrypt everything! Encrypt your data at rest in AWS across your storage options. Automation and omnipresent, that's how you should design your encryption. Encrypting data helps you in the following ways:
Privacy
Integrity
Reliability
Anonymity
Use KMS: Encryption using keys rely heavily on availability and security of keys. If you have the key, you have the data. Essentially, whoever owns the key, owns the data. So, ensure that you use a reliable and secure key management infrastructure for managing all your keys. AWS KMS is a fully managed service available for all your key management needs. Use this to manage your keys for encrypting data in S3, RDS, EBS volumes, and so on. Also, ensure that you control access to these keys through IAM permissions and policies.
Rotate your keys: Ensure that keys are rotated periodically, usually quite frequently. The longer a key lives the higher is the security risk attached to it...
