2fa access to DWC or RestAPI

Actually, the user must identify himself with an userid/password.

To enhance the security and make it easier for the lambda user, We have the need being able to use either 2FA or Certificate-based logons to the web-interface of Dynamic Workload Console.

Since DWC is using Websphere Liberty it could very well be that the authentication/authorization is actually done by Liberty. The fact that the initACEE is not mentioned in DWC doesn’t necessarily mean it’s not being used by Liberty. (end user certificate with parameter and callable service aka hostIdMappings -> initACEE)

An comparaison from our colleagues  with an IBM-BMC solution hint that is possible : 

I have just learned that BMC AMI OPS UI depends on the certificate of the end user to control the identity against RACF before granting any access

If we decide to use an web-proxy in between the end user and the MainFrame Web-GUI, then we can not provide the required end user certificate to the Web-GUI and therefore the certificate based login as described below is not possible.

 

To evaluate other possibilities, we need someone who ca explain us the service IRRSIA0  and if it might be possible to provide another similar service for the UBS iSSO solution…

Can you please help to identify such an SME for the service IRRSIA0

 

 

When RACF® is called by initACEE to determine the user ID to associate with the client certificate, it does so based on your installation's set of certificate mapping rules.

 

In UBS we have the hostid mapping extension in use https://www.ibm.com/docs/en/zos/2.2.0?topic=service-using-hostidmappings-extension

 

Authorized applications, such as Web servers, can present a client's certificate containing a hostIdMappings extension and invoke the initACEE callable service (IRRSIA00) to request to have a security context (ACEE) created or have the client's user ID queried and returned. 

 

IRRSIA00: https://www.ibm.com/docs/en/zos/2.2.0?topic=services-initacee-irrsia00-callable-service

 

Authorized applications, such as Web servers, can also present a client's certificate containing a hostIdMappings extension and invoke the initACEE callable service to request to have a security context (ACEE) created or have the client's user ID queried and returned.

    The 2FA authentication on the DWC is already supported through the OpenID standard.


    OpenID is a widely used decentralized authentication protocol that allows users to log in to multiple applications with a single set of credentials. In other words we decided not to implement this feature internally to the DWC but to enable it with the identity management tools that all organizations already use in their environment.


    If your identity management tool supports OpenID, it means you can enable two-factor authentication for added security. Users would not only need their usual login credentials but also a secondary authentication factor, such as a verification code sent to their mobile device. This extra layer of security significantly reduces the risk of unauthorized access and enhances overall protection.
