Creating a basic access level

Console

To create a basic access level:

1. Open the Access Context Manager page in the Google Cloud console.

   Open the Access Context Manager page

2. If you are prompted, select your organization.

3. At the top of the Access Context Manager page, click New.

4. In the New Access Level pane:

   1. In the Access level title field, enter a title for the access level. The title must be at most 50 characters, start with a letter, and can contain only numbers, letters, underscores, and spaces.

   2. In the Conditions section, click the add button for the type of attribute you want to add, and then provide the values you want applied to that attribute.

      For a complete list of the attributes you can add, read about access level attributes.

      For example, if you want the access level to consider where a request is coming from within your network, you would select the IP Subnetworks attribute.

      Repeat this step to add multiple attributes to the same condition. When a condition has multiple attributes, all of the attributes must be met by the access request.

      An access level condition can include one of each type of attribute. Some attributes include additional options, such as the Device Policy attribute.

      Access levels support conditions based on user identity. However, to add identities to a condition, you must create or update the access level using the gcloud CLI or the API.

   3. Use the When condition is met, return option to specify whether you want the condition to require that a request meet all specified attributes (TRUE) or whether the request must meet anything but those attributes (FALSE).

      For example, if you want to deny requests from a certain IP address range of your network, specify the IP address range using the IP Subnetworks attribute and then set the condition to FALSE.

   4. Optionally, click Add another condition to add an additional condition to your access level and then repeat the previous two steps.

      For example, if you want to deny access to a subset of IP addresses within a broader IP address range, create a new condition, specify the subset IP address range for the IP Subnetworks attribute, and set the condition to return FALSE.

      Repeat this step to add multiple conditions to the same access level.

   5. If you created more than one condition, use Combine condition with to specify whether you want the access level to require a request to meet at least one of the conditions (OR), or all of the conditions (AND).

   6. Click Save.

gcloud

Before you begin

• If it doesn't exist yet, create an access policy for your organization.

To create an access level using the gcloud command-line tool, use the gcloud access-context-manager levels create command.

gcloud access-context-manager levels create LEVEL_NAME OPTIONS \
    --policy=POLICY

Where:

• LEVEL_NAME is the unique name for the access level. It must begin with a letter and include only letters, numbers, and underscores. The name can be a maximum of 50 characters.

• OPTIONS are the required options from the following table.

  Options
  basic-level-spec	A YAML file that specifies one or more conditions for the access level.
  title	A short title for the access level. The access level's title is displayed in the Google Cloud console.
  combine-function	(Optional) Determines how conditions are combined. Valid values: AND, OR
  description	(Optional) A long-form description of the access level.

• POLICY is the ID of your organization's access policy. If you have a default policy set, this parameter is optional.

Optionally, you can include any of the gcloud-wide flags.

basic-level-spec YAML file

When you use the gcloud command-line tool to create an access level, you must provide a YAML file for the basic-level-spec option. The YAML file defines one or more conditions for the access level. Conditions must contain at least one attribute. When a condition contains more than one attribute, they are combined as either an AND operation (all must be true) or as a NAND operation (none can be true), depending on whether the negate attribute is included in the condition.

For a complete list of the attributes you can include in your YAML file, read about access level attributes.

For more information about access levels and YAML, refer to the example YAML for an access level.

Example command

gcloud access-context-manager levels create Device_Trust \
    --basic-level-spec=corpdevspec.yaml \
    --combine-function=AND \
    --description='Access level that conforms to corporate spec.' \
    --title='Device_Trust Extended' \
    --policy=1521580097614100

API

Before you begin

• If it doesn't exist yet, create an access policy for your organization.

To create an access level, call accessLevels.create.

POST https://accesscontextmanager.googleapis.com/v1/accessPolicies/POLICY/accessLevels

Where:

• POLICY is the ID of your organization's access policy.

Request body

The request body must include an AccessLevel resource that specifies the conditions you want for the new access level. Each Condition has one or more attributes that are evaluated as an AND operation (all must be true) or as a NAND operation (none can be true) depending on whether the negate field is set to true. The resulting evaluation determines whether the condition is met or not.

Response body

If successful, the response body for the call contains an
