Access groups and policies management

Manage access groups and policies to efficiently organize users and service IDs, streamline permissions, and enhance access control for Kyndryl Bridge services.

Access groups

Access groups allows you to add or remove users or service IDs to the access group, as well as assigning it one or more access policies that could continue to be managed in a centralized construct, instead of adding the same access policies individually to all users or service IDs; this facilitates the onboarding experience by managing just a few steps in the process.
Users with an
Administrator
 role, which is the out-of-the-box role granted when the Kyndryl Bridge services account is first created, can add the access groups. Likewise, other users can also manage access groups if the access policies they are part of have the correspondent permissions. To understand which roles and permissions are required, see roles and permissions.
Accessing the access group page
The Access Groups page allows you to create, edit, and view access groups. At the same time, you can add and remove users from the access groups, and even create an access policy into the access groups. In this way, you can control your access management needs quickly and efficiently.

Nested access groups

Nested access groups allow administrators to assemble access groups together. To simplify the permission administration for a large number of users, the administrator organizes the access and creates a collection of different access groups. The clusters, which will inherit the access policies from the existing access groups, are known as nested access groups. Any access group can continue to work as normal or establish itself as the parent access group if no IDs or service IDs are associated to them. Access groups with any ID affiliation can become nested access groups once they are linked to a parent access group.
Prerequisites
  • Parent access groups must be empty and have no IDs affiliations.
  • Nested access groups are the only ones that have service IDs and user IDs associated with them.
  • Hierarchy is limited up to 1 level of access groups.
Adding a nested access group
  1. From the
    Kyndryl Bridge Console
     Home page access the secondary menu.
  2. From the
    App Manager
     dropdown, select
    IAM
    . The IAM page opens.
  3. Select
    Access Groups
     from the left navigation bar of the page.
  4. Click the overflow menu next to the access group to be the parent and select
    View Details
    .
  5. Click
    Add Nested Access Groups
    .
  6. Select the parent access group from the list by checking the box next to it.
  7. Click
    Add
    . Otherwise, click
    Cancel
    .
  8. A message confirming your action will be displayed.

Access policies

Access policies allow you to grant role(s) and permission(s) to a specific group of resources and targets. The main benefit of assigning an access policy to an access group is that it makes all members of that group inherit the same permissions. 
Basically, an access policy is the way in which an access group gets permission to perform actions for Bridge Common Services. An access policy includes a Subject (User IDs, Services IDs, Access Groups), a Target (associates resources), and a Permission (associates roles). To understand which roles and permissions are required, see roles and permissions. Imagine the following scenario where you want to create an access policy using Kyndryl Bridge IAM infrastructure:
I want to give a subject...
... access to a target
.
.. with specific permissions
  • User
  • Service ID
  • Access group (combination of user and service IDs)
  • IAM resources: of one or more resource types (policies, access group, and so on) 
  • Application resources: of one or more resource types (orders, catalogs, budgets, DRGs, VMs, Kubernetes Cluster, builds, repositories)
  • Common Services roles:
    • Administrator
    • Editor
    • Viewer
    • Operator 
  • App Roles:
    • App Role 1
    • App Role 2 
  • Custom role: Created based on the existing out-of-the-box roles permissions available.
