Provide ability to decrypt encrypted query/path parameters in a GET request

The API consumer need to pass a client card / credit card number to retrieve account information such as account balance or mortgage information with a GET method. Even though the request URL is protected in transport layer with TLS/SSL, the URL can be logged by API gateway, network devices and z/OS Connect which does not meet the bank's data security requirements.

    This requirement has been evaluated.

    Security recommendation for information deemed sensitive enough to encrypt in transit through distributed systems is that it is only decrypted at the point it is needed. If the value is decrypted in z/OS Connect EE before being passed onto further systems there is still a risk of it being logged either in z/OS Connect EE or in any of the systems and networks it then goes through. The recommendation would be for the caller to encrypt the sensitive value, use the encrypted value in the API as normal (path parameter, query parameter etc), have z/OS Connect EE map the value to the desired copybook field and passed through the Z infrastructure, and have the target application decrypt the value when it is required.

    Due to the conflicts with secure engineering practices that this enhancement request creates, it is not likely that this would be implemented in future zOS Connect EE releases, so correspondingly this requirement is being rejected. You have an opportunity to resubmit in twelve months time if you wish it to be considered then.
