**1. To create a security configuration with in-transit encryption enabled with PEM for certificate provider, and at-rest encryption enabled with SSE-S3 for S3 encryption and AWS-KMS for local disk key provider**

- Command::

	 aws emr create-security-configuration --name MySecurityConfig --security-configuration '{
		"EncryptionConfiguration": {
			"EnableInTransitEncryption" : true,
			"EnableAtRestEncryption" : true,
			"InTransitEncryptionConfiguration" : {
				"TLSCertificateConfiguration" : {
					"CertificateProviderType" : "PEM",
					"S3Object" : "s3://mycertstore/artifacts/MyCerts.zip"
				}
			},
			"AtRestEncryptionConfiguration" : {
				"S3EncryptionConfiguration" : {
					"EncryptionMode" : "SSE-S3"
				},
				"LocalDiskEncryptionConfiguration" : {
					"EncryptionKeyProviderType" : "AwsKms",
					"AwsKmsKey" : "arn:aws:kms:us-east-1:123456789012:key/12345678-1234-1234-1234-123456789012"
				}
			}
		}
	}'

- Output::

    {
    "CreationDateTime": 1474070889.129,
    "Name": "MySecurityConfig"
    }
