What are friendly accounts in Conformity?

A Friendly account is the one that is allowed to access resources on another account because it is trusted. Once a Friendly account is added to the relevant rules, it will result in a success check after a Conformity Bot scan.

Account Administrators explicitly allow specific actions or behaviours for friendly accounts. These accounts may have access to a limited set of functionality deemed safe by the administrator.

For example:

AWS Account A has access to resources in AWS Account B. Both accounts may or may not be owned by the same company or Account A might just “trust” the Account B from AWS console.

In this case, Account B would be a friendly (trusted) account to Account A as determined by the customer. Therefore certain rule failures caused by Account B are excluded from the check.

How do I configure Friendly accounts for a rule?

Please Note:: Configuring a rule with friendly accounts will allow users who do not have access to these accounts to view their AWS Account IDs in the rule check.

  1. Click on the Configure Rule button on the account from the list of supported rules.
  2. You can add Friendly accounts by either selecting one or more of the following options: :
    1. Manual addition (For All Users): enter the account name in the text box and click on the Add new button.
    2. Accounts within your AWS Organization (For Admin Users Only)
      1. Select this option to include all accounts in your AWS organization as friendly accounts.
        Notes:
        • This option will only work for the AWS account in Conformity that is also your AWS Organization’s management account as it requires access to account Ids of all accounts in your AWS Organization.
        • For the rule VPC-006 - VPC Endpoint Cross Account Access only - All users can add friendly accounts using this option.
    3. All within this Conformity organization (For Admin Users Only)
      Select this option to include all AWS accounts in the current Conformity Organization as friendly accounts.
    4. All with the following Conformity tags (For Admin Users Only)
