Manage access bindings

This page explains how to manage your existing access bindings, which define how access policies are applied to your user groups. You can view, modify, and delete these bindings as needed. Access bindings determine how access levels and session controls are applied to a user group.

For information about how to create access bindings and for more details on access levels and session controls, see Apply policies to user groups with access bindings.

View access bindings

After the access bindings are created for a group of users, access to the Google Cloud console and Google Cloud APIs are controlled based on satisfaction of the bound access level.

You can view the details of the access binding that you created, edit it, or delete it.

Console

In the Google Cloud console, go to the Access Context Manager page.

Go to Access Context Manager
If you are prompted, select a project. The list of access bindings are listed on the Access Context Manager page.

gcloud

To view all access bindings, run the following command:
```
  gcloud access-context-manager cloud-bindings list \
   --organization ORG_ID
```
ORG_ID: Your organization ID. If the access-context-manager/organization property hasn't been set, replace ORG_ID in the optional --organization flag with the ID for the organization that you used when creating the GcpAccessAdmin role.
To view the details of an access binding, run the following command:
```
  gcloud access-context-manager cloud-bindings describe \
  --binding=BINDING_ID
```
BINDING_ID is the ID of the access-binding or fully qualified identifier for the access binding.

API

View all access bindings:

Before using any of the request data, make the following replacements:
- ORG_ID is the ID for the organization that you used when creating the GcpAccessAdmin role. If the access-context-manager/organization property hasn't been set, replace ORG_ID in the optional --organization flag with the ID for the organization that you used when creating the GcpAccessAdmin role.
HTTP method and URL:

Update an access binding

You can update an access binding to do the following:

Add, remove, or change which applications have a policy.
Modify the access levels for an application within a user group.
Add a new dry run access level or promote an existing one to a live level.

Console

In the Google Cloud console, go to the Access Context Manager page.

Go to Access Context Manager
If you are prompted, select a project.
On the Access Context Manager page, select an access binding and then click Edit to update it.

You cannot update access bindings with dry run access levels or session controls in the Google Cloud console.

gcloud

Create a YAML binding file.
```
gcloud access-context-manager cloud-bindings update
  --binding ACCESS_BINDING
  --binding-file BINDING_FILE_PATH
[  --level DEFAULT_ACCESS_LEVEL ]
[  --dry-run-level DEFAULT_DRY_RUN_ACCESS_LEVEL           ]
[  --session-length=DEFAULT_SESSION_LENGTH                ]
[  --session-reauth-method=DEFAULT_SESSION_REAUTH_METHOD  ]
```
Replace the following:
- ACCESS_BINDING is in the form organizations/ORG_ID/gcpUserAccessBindings/ACCESS_BINDING_NAME.
- BINDING_FILE_PATH: The path to the YAML file that contains the access binding scheme. The binding file supports only scopedAccessSettings.
- DEFAULT_ACCESS_LEVEL: The optional access level name, which takes the form accessPolicies/POLICY_ID/accessLevels/ACCESS_LEVEL_NAME. Replace POLICY_ID with the access policy ID, and ACCESS_LEVEL_NAME with the access level name.
- DEFAULT_DRY_RUN_ACCESS_LEVEL_2: An optional access level name in the form `accessPolicies/POLICY_ID/accessLevels/ACCESS_LEVEL_NAME`. Include this flag to apply the specified dry run access level to all applications by default if they aren't specified in the YAML.
- DEFAULT_SESSION_LENGTH: The optional session duration using ISO 8601 duration format, such as 30m for 30 minutes, or 2h for two hours.
- DEFAULT_SESSION_REAUTH_METHOD: The optional method to challenge users to re-verify their identity, which must be one of the following:
  - LOGIN: Apply the standard login, which can include MFA or other Workspace-defined factors.
  - PASSWORD: Only require a password, even if other factors are defined. If passwords are managed using an external IdP, users are redirected to the IdP. If the IdP session is live, users are implicitly re-authenticated. If the IdP is not live, users must sign in through the IdP.
  - SECURITY_KEY: Require a hardware security key.
How the --level and --binding-file arguments work together
- If you only use --binding-file, only the applications in the file have the policies applied.
- If you only use --level, the access level applies to all applications.
- If you use both, the rules are combined. The --level value applies to all applications, whereas the policies in the YAML file specified by --binding-file only apply to the applications as defined in the file.
Working with session controls
- To set default session controls for all applications, use --session-length and --session-reauth-method.
- If you also define session controls in the YAML file, those session controls override the default settings for those specific applications.
- You must use --session-length and --session-reauth-method together.
To remove a default access level or a default dry run access level, provide an empty string, such as --level= or --dry-run-level=. When these arguments are not provided, the update command won't make any changes.

To remove a session control, set --session-length=0.

API

Create a JSON body.
```
{
  "accessLevels": [
    "DEFAULT_ACCESS_LEVEL"
  ],
  "scopedAccessSettings": [
    {
      "scope": {
        "clientScope": {
          "restrictedClientApplication": {
            "clientId": "CLIENT_ID"
          }
        }
      },
      "activeSettings": {
        "accessLevels": [
          "ACCESS_LEVEL_A"
        ],
        "sessionSettings": [
          {
            "sessionLength": "SESSION_LENGTH",
            "sessionReauthMethod": "SESSION_REAUTH_METHOD",
            "sessionLengthEnabled": true
          }
        ]
    }
    },
    {
      "scope": {
        "clientScope": {
          "restrictedClientApplication": {
            "name": "CLIENT_NAME"
          }
        },
        "activeSettings": {
          "accessLevels": [
            "ACCESS_LEVEL_C"
          ]
        }
      }
    }
  ]
}
```
Replace the following:
- DEFAULT_ACCESS_LEVEL: The optional access level name, which takes the form accessPolicies/POLICY_ID/accessLevels/ACCESS_LEVEL_NAME. Replace POLICY_ID with the access policy ID, and ACCESS_LEVEL_NAME with the access level name.
- CLIENT_ID: The OAuth client ID. You must use clientId when an application contains sessionSettings.
- ACCESS_LEVEL_A: An access level name in the format accessPolicies/POLICY_ID/accessLevels/ACCESS_LEVEL_NAME.
- SESSION_LENGTH: The session duration using ISO 8601 duration format, such as 30m for 30 minutes, or 2h for two hours.
- SESSION_REAUTH_METHOD: The optional method to challenge users to re-verify their identity, which must be one of the following:
  - LOGIN: Apply the standard login, which can include MFA or other Workspace-defined factors.
  - PASSWORD: Only require a password, even if other factors are defined. If passwords are managed using an external IdP, users are redirected to the IdP. If the IdP session is live, users are implicitly re-authenticated. If the IdP is not live, users must sign in through the IdP.
  - SECURITY_KEY: Require a hardware security key.
- CLIENT_NAME: The client name. If the application contains sessionSettings, you cannot use the client name. Instead, use the OAuth client ID.
- ACCESS_LEVEL_C: An access level name in the format accessPolicies/POLICY_ID/accessLevels/ACCESS_LEVEL_NAME.
Send the PATCH request.
```
PATCH https://accesscontextmanager.googleapis.com/v1/ACCESS_BINDING?fieldMask=FIELDMASK
```
Replace the following:
- ACCESS_BINDING is in the form organizations/ORG_ID/gcpUserAccessBindings/ACCESS_BINDING_NAME.
- FIELD_MASK: A required, comma-separated list of fields that you want to update. This tells the API which parts of the access binding to modify.
fieldMask should contain the top-level JSON keys in the request body that you want to update, which can contain accessLevels, dryRunAccessLevels, and scopedAccessSettings.

Important: If you don't include a fieldMask, nothing is updated.

If successful, you should receive a representation of the JSON object. If there is a problem, you receive an error message.
