Audio Logs Encrypted

Ensure that Amazon Lex audio logs are encrypted using desired KMS encryption level

For audio logs you use default encryption on your S3 bucket or specify an AWS KMS key to encrypt your audio objects. Even if your S3 bucket uses default encryption you can still specify a different AWS KMS key to encrypt your audio objects for enhanced security.

Encrypt Lex audio logs with customer-manager keys (CMKs) present in your account
