Set up for data encryption

You can use cryptographic keys stored and managed in your AWS account KMS to encrypt your organization's data stored in Gong.

For Gong to use the external CMK (Customer Managed Key), two conditions must be satisfied:

The CMK should have a policy that allows a Gong-owned principal (specifically an IAM role), to use the CMK with a set of predefined permissions, for example, Encrypt or Decrypt.
The principal should have an attached policy to use the CMK with appropriate permissions.

To satisfy these conditions, your administrator must set up the CMK in your AWS account as explained in this article.

Required permissions

This table explains the permissions we need for your key and why:

Permission	Why we need the permission
Decrypt Encrypt GenerateDataKey	To enable Gong to store encrypted files for your organization.
DescribeKey	To enable Gong to verify that the key is a symmetric key that meets requirements.
ListGrants	To enable Gong to list existing grants for the CMK.
CreateGrant	To enable Gong to delegate permissions dynamically from the ExternalCmkAccessGranter principal to the various services in Gong that store and read encrypted data.
RevokeGrant RetireGrant	To enable Gong to remove the created grant, retire in regular cases, and revoke if some services get forcefully shutdown.

Create and configure your CMK

Make sure your region is us-east-1.
In AWS KMS, create a symmetric encryption.

When you are asked to add a policy, paste the following snippet to enable access from the Gong AWS account:

{            
    "Sid": "Allow Gong.io to use this CMK",
    "Effect": "Allow",
    "Principal": {
"AWS":"arn:aws:iam::655275192472:role/ExternalCmkAccessGranter"            
    },
    "Action":[                
    "kms:Decrypt",
    "kms:Encrypt",
    "kms:RevokeGrant",
    "kms:GenerateDataKey",
    "kms:DescribeKey",
    "kms:RetireGrant",    
    "kms:CreateGrant",
    "kms:ListGrants"
    ],
    "Resource": "*"        
}

After the CMK is created, make a note of the CMK’s ARN, for example:

arn:aws:kms::1234567890:key/12345678-90ab-cdef-1234-123456789ab

This is the key you need when you encrypt your organization's data in Gong.
