To upgrade, [contact our sales team](https://go.chronicle.security/beyondcorp-enterprise-upgrade).\n- Ensure that you have one of the following Identity and Access Management roles:\n - Access Context Manager Admin (`roles/accesscontextmanager.policyAdmin`)\n - Access Context Manager Editor (`roles/accesscontextmanager.policyEditor`)\n- Understand the objects and attributes that are used to build the [Common Expression Language (CEL)](https://opensource.google.com/projects/cel) expressions for custom access levels. For details, see [Custom access level specification](/access-context-manager/docs/custom-access-level-spec).\n\nCreate custom access levels\n---------------------------\n\nYou can create access levels with one or more conditions. If you want the users'\ndevices to satisfy multiple conditions (a logical AND of conditions), create\nan access level that contains all the required conditions.\n\nTo create a new custom access level using the data provided by Intune, do the\nfollowing:\n\n1. Go to the **Access Context Manager** page in the Google Cloud console.\n\n [Go to Access Context Manager](https://console.cloud.google.com/security/access-level)\n2. If you are prompted, select your organization.\n3. On the **Access Context Manager** page, click **New**.\n4. In the **New Access Level** pane, enter the following:\n 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.\n 2. In the **Create Conditions in** section, select **Advanced Mode**.\n 3. In the **Conditions** section, enter the expressions for your custom access level. The condition must resolve to a single boolean value.\n\n To find the available Intune fields for your CEL expression, you can review the\n [Intune data](/chrome-enterprise-premium/docs/setting-up-intune#verify-client-data)\n collected for your devices.\n **Examples**\n\n The following CEL expression creates a rule that allows access only from\n Intune-managed devices that are compliant: \n\n ```scdoc\n device.vendors[\"Intune\"].is_managed_device == true && device.vendors[\"Intune\"].data[\"complianceState\"] == \"compliant\"\n ```\n\n The following CEL expression creates a rule that allows access only from devices that Intune synced in the last three days. The `lastSyncDateTime` field is provided by Intune. \n\n ```text\n request.time - timestamp(device.vendors[\"Intune\"].data[\"lastSyncDateTime\"]) \u003c duration(\"72h\")\n \n ```\n | **Note:** Chrome Enterprise Premium can take up to 60 minutes to pull updates from Intune, and Intune syncs only a few times in a day if the device is active. Therefore, we recommend accommodating this schedule when planning the freshness duration.\n\n For examples and more information about Common Expression Language\n (CEL) support and custom access levels, see the [Custom access level specification](/access-context-manager/docs/custom-access-level-spec).\n 4. Click **Save**.\n\nAssign custom access levels\n---------------------------\n\nYou can assign custom access levels to control access to\napplications. These applications include [Google Workspace](https://workspace.google.com/) apps\nand the applications that are protected by [Identity-Aware Proxy](/iap/docs/concepts-overview)\non Google Cloud (also known as IAP-secured resource).\nYou can assign one or more access levels for the apps. If you\nselect multiple access levels, users' devices only need to satisfy the conditions in **one**\nof the access levels to be granted access to the app.\n| **Note:** If you want user devices to satisfy conditions in more than one access level (a logical AND of access levels), create an access level with all the required conditions.\n\n### Assign custom access levels for Google Workspace applications\n\nAssign access levels for Google Workspace applications\nfrom the Google Workspace Admin console:\n\n1. From the Admin console Home page, go to **Security \\\u003e Context-Aware Access**.\n\n [Go to Context-Aware Access](https://admin.google.com/u/1/ac/security/context-aware)\n2. Click **Assign access levels**.\n\n You see a list of apps.\n3. In the **Organizational units** section, select your organizational unit or group.\n4. Select the app for which you want to assign an access level, and click **Assign**.\n\n You see a list of all access levels. Access levels are a shared resource\n between Google Workspace, Cloud Identity, and Google Cloud so you\n might see access levels that you didn't create in the list.\n5. Select one or more access levels for the app.\n6. To apply the access levels to users on desktop and mobile apps (and on the browser), select **Apply to Google desktop and mobile apps**. This checkbox applies to built-in apps only.\n7. Click **Save**. The access level name displays in the assigned access levels list next to the app.\n\n### Assign custom access levels for IAP-secured resources\n\nTo assign access levels for IAP-secured\nresources from the Google Cloud console, follow the instructions in\n[Apply an access level for IAP-secured resources](/chrome-enterprise-premium/docs/access-levels#applying_an_access_level).\n\nWhat's next\n-----------\n\n- [Monitor device inventory](/chrome-enterprise-premium/docs/view-inventory-intune)"]]
