Import OpenAPI Specification to Define API Definition

Published April 5, 2023 | Last modified November 20, 2024

Objective

This guide provides instructions on how to import an OpenAPI Specification (formerly Swagger) file to define API groups and set rules to control access to APIs, enabling granular API access control ability. To learn more about security concepts, see Security.

Enabling this feature includes preparing the OpenAPI Specification files for your API definitions, importing them to F5 Distributed Cloud Services, and applying them to your load balancer. Also, you can enable API validation to ensure that traffic to your API complies with a specified schema.

Using the instructions provided in this guide, you can import OpenAPI Specification files, attach them to your load balancer, and apply service policies to restrict access to the API groups defined in the OpenAPI Specification files.

OpenAPI Validation

Many issues in the Open Web Application Security Project (OWASP) API Security Top 10 list are triggered because of missing input validation. To protect APIs from such issues, OpenAPI Validation is used. The OpenAPI Validation enables you to ensure that traffic to your API complies with a specified schema. If the traffic does not conform to your API schema, you can enable action to block the traffic, ensuring the security and integrity of your API.

OpenAPI Validation offers flexibility to configure validation of traffic on a per-endpoint, per-group, or per-base-path basis, so that you can customize the validation to suit your specific requirements.

In addition to blocking non-compliant traffic, OpenAPI Validation also supports reporting and allowing actions. It also supports identifying Shadow APIs and actions to report or block traffic to Shadow APIs. For more information on Shadow APIs, see API Endpoint Discovery and Schema Learning guide.

Note: The report action allows the traffic while raising an API security event.

OpenAPI Validation allows specifying of Allowed IPs list. This list can include specific IP addresses for which you want to skip validation, allowing you to control who has access to your API. Also, OpenAPI Validation can be enforced according to the authentication scheme that you have defined for your API. By doing so, you can ensure that only authenticated users can access your API, further enhancing the security of your system.

Prerequisites

The following prerequisites apply:

F5 Distributed Cloud Services Account. If you do not have an account, see Create an Account.
An HTTP load balancer advertising your application. For instructions on creating load balancer, see HTTP Load Balancer. See the vK8s Deployment guide for deploying your applications on the F5 Distributed Cloud's Network Cloud or Edge Cloud.

Configuration

You can create the API definition as part of the HTTP load balancer configuration or separately using the Manage > API Definition option. This guide presents instructions on creating a separate API definition and later applying it to a load balancer.

Importing OpenAPI Specification files to define API groups and control access to those groups includes the following sequence of activities:

Prepare OpenAPI Specification files containing API groups and definitions and import them using Console.
Define service policy to control access to the API groups.

Import OpenAPI Specification Files and Create API Definitions

Perform the following to prepare and import OpenAPI Specification files containing API groups and definitions.

Step 1: Prepare OpenAPI Specification files.

Prepare OpenAPI Specification files on your local machine with the API groups and definitions per your requirements.

The following are sample files for your reference. One file is for user API and the other file is for REST API:

Click Save and Exit to create file objects in Console.
Repeat the previous steps for importing more files.

Step 3: Create API definition.

In Web App & API Protection service, select Manage > API Management > API Definition.

Note: You can also add and edit definitions in Multi-Cloud App Connect> Manage > Load Balancers > HTTP Load Balancers.

Click Add API Definition.

Figure: Create API Definition

Enter Name in metadata section.
In OpenAPI Specification Files section, click Add Item to add a file.
From the File Path menu, select existing file or select Upload Swagger file to upload a new file.

Figure: Create API Definition

Step 3.1: Optionally, manage your inventory of endpoints.

In the API Endpoints Management section, enable Show Advanced Fields.

Figure: API Endpoints Management

Perform the following:
- API Inventory Inclusion List: This lists the endpoints in your inventory that are not in your file. You can configure them here, or you can view them here after moving a discovered endpoint to inventory in security monitoring for this load balancer.
- API Inventory Exclusion List: These are the endpoints from your file that you are excluding from your inventory. You can configure them here, or you can view them here after removing them from inventory in security monitoring for this load balancer.
- API Discovery Exclusion List: These are discovered endpoints that are not part of your API. You can view them here after marking them as Non-API in security monitoring for this load balancer.
- Schema Updates Strategy drop-down list: Used to specify how to work with API Inventory that is associated with multiple AppTypes:
  - Strict Schema Origin: Restricts schema updates to a single AppType. The origin of the schema update is stored and validated separately for each endpoint.
  - Mixed Schema Origin: The schema can be updated from all associated load balancers.
Click Save and Exit to create API definition object in Console.

Step 4: Add API definition to load balancer.

In the Web App & API Protection, select Manage > Load Balancers > HTTP Load Balancers.
In the Actions column for your load balancer, select Manage Configuration. Select Edit Configuration in the upper right corner to edit your load balancer.
In the API Protection section, use the API Definition drop-down menu to select Enable.
Select one of your API definitions from the API Definition drop-down menu.

Step 5: Optionally, configure OpenAPI validation.

Validation is disabled by default. You can select Disable from the Validation menu to turn off validation at any time.

Select an option from the Validation drop-down and configure per the options.

Step 5.1: Enable validation for all endpoints specified in API Inventory.

Select API Inventory. Click View Configuration.
Select Validate or Skip for the OpenAPI Validation Request Processing Mode menu to enforce validation or skip validation, respectively.
Select Report or Block for the Request Validation Enforcement Type to report or block the traffic, respectively. In case of reporting, the traffic is allowed along with triggering an API security event.
Select validation parameters from the OpenAPI Validation Response Processing Mode drop-down to specify which parameters should be validated with the specification. You can add more than one parameter.
After you finish with configuration, click Apply.

Step 5.2: Enable validation for specific endpoints in API Inventory.

Select Custom List to set specific list of endpoints. Click View Configuration.
Click Configure under Validation List.
Select Add Item in the validation list page, and enter a name for the list in the DNS-1035 format.
Set the OpenAPI Validation Request Processing Mode option.
Select Any Domain or Specific Domain from the Domain menu. In case of specific domain, enter a domain in the Specific Domain field. You can also use the See Suggestions option to choose from one of the suggested values.
Select an option from the Type drop-down menu to set a specific endpoint type. You can select a group or specific endpoint or a specific base path. In case of selecting a specific endpoint, enter a path in the Path field, and select methods from the Methods drop-down menu. You can select more than one method or set ANY method.
Select Apply to apply the list to the validation list page. Select Apply in the validation list page to apply the custom list to the validation settings in the API protection section of load balancer.
Configure the Fall Through Mode option to specify action for endpoints that are not specified in the file or in the custom rules list. By default, the fall through mode is to allow traffic for endpoints that are not specified in the file. Change the setting to Custom to control the traffic to these endpoints in a granular manner per the following guidelines:
- Click Configure under Custom Fall Through Rule List to open the custom list page and select Add Item.
- Enter a name for the list item in the DNS-1035 format.
- Select Skip, Report, or Block for the Action drop-down menu to skip processing or report or block the traffic, respectively. Report option allows the traffic while raising an API security event.
- Select an option from the Type drop-down menu to set a specific endpoint type. You can select a group or specific endpoint or a specific base path. In case of selecting a specific endpoint, enter a path in the Path field, and select methods from the Methods drop-down menu. You can select more than one method or set ANY method.
- From the OpenAPI Validation Response Processing Mode menu, select Validate to check for OpenAPI mismatches, and then perform the following:
  - From the Response Validation Enforcement Type menu, select Report to only notify of a violation or Block to prevent the mismatches.
  - From the Response Validation Properties menu, select the properties in the response to validate. You can choose from the three options provided.

Figure: Validate Response for OpenAPI Mismatch

Note: The custom error responses feature is not supported for OpenAPI Validation.

Select Apply to apply the list to the validation list page. Select Apply in the validation list page to apply the custom list to the validation settings in the API protection section of load balancer.

Step 6: Apply API definition to load balancer.

Click Save and Exit to save your load balancer configuration.

Figure: Select an API definition

Step 7: Create API group.

Select Manage > API Management > API Groups.
Select Add API Group.

Figure: Create API Groups

Enter a Name in metadata section.
In the API Endpoints section, select a load balancer from the HTTP Load Balancer drop-down menu. This will expand the API Endpoints section to show more options as well as a table of your existing endpoints (if you uploaded a file). If you did not upload a file, then the endpoints will be discovered as the load balancer operates.

Figure: Create API Group

Note: By default, none of the endpoints in this table are included in your new group. You can configure the API group to include endpoints now as part of its creation, or you can configure it later.

Configure your API group using the Include Path Matches and Include Label Matches fields and the options in the Actions column. The result will be to modify the states for each endpoint with respect to this group. In the example below, no endpoints are included in the group, so the only action available is Include. Selecting Include for a path will force its inclusion in the group regardless of other selections.

Figure: Configure API Group

Include Path Matches: Enter a path substring to select matching API endpoints into the group. Endpoint paths that include the entered string will have their states changed to "included" which is denoted by a circled check mark. Also, the action for this state is Exclude, which would remove the endpoint from the group even though it matches the include path string you entered.

Figure: API Group Path Matches

Include Label Matches: Use this field to create one or more labels to match. To create a label, select Add Label and then select a key, an operator, and a value/type (if necessary). This will include all endpoints that match the label. If you have multiple labels, all labels must match for an endpoint to be included. If you have both a path match and a label match, then only endpoints that match both will be included.

Figure: API Group Label Matches

State Column: The column entry shows whether the endpoint is included (circled check mark) or not included (circled minus sign). If the circled check mark is green, the endpoint was included manually. If the circled minus sign is red, the endpoint was excluded manually. States that are set manually can be changed using the Reset option in the Actions column.

Endpoint state counts bar: Just above the table header is a set of counts to help you understand the group as a whole.

Superset: The first count is the number of endpoints in the superset (all endpoints that are known). This number can change as new endpoints are discovered, or endpoints are removed. Endpoints that are discovered (added to the superset) will go through the same match process to possibly include them in the group; however, they are not included unless you edit the group and then select Save and Exit. Endpoints that are removed will have their API Category set to Not in Superset (currently not available). For endpoints that are no longer in the superset, the action is Delete (remove it from the table). You might not want to remove the endpoint if you expect the endpoint to add to the superset at a later date, which would allow it to automatically return to its prior configuration/state.
Match: This shows the number of endpoints is included by match, including those that are not shown in the table due to the items per page setting or the Search entry. Manually excluded endpoints do not affect this count.
Excluded Manually: This shows the number of endpoints manually excluded from the match. If this value is non-zero, there is a Reset option to undo all manual excludes.
Included Manually: This shows the number of endpoints manually included in the group. If this value is non-zero, there is a Reset option to undo all manual includes.

Figure: API Group State Column

Select Save and Exit to save the configuration changes.

Step 8: Update API group.

In the Web App & API Protection, select Manage > API Management > API Groups to see a list of your API groups. Each row represents a group and shows the group name, the load balancer it works with, how many endpoints are included in the group, when it was created, and if any endpoints have been added to the group since you last configured it (Updated Endpoints column).

Figure: API Groups

Select Manage Configuration from the Actions menu for your load balancer. Then select Edit Configuration to allow configuring of the group. Make configuration changes as described in the previous step.
Select Save and Exit to save the configuration changes.

Note: If you have newly discovered endpoints, and those endpoints were included by match, then selecting Save and Exit will automatically include those matched endpoints into the group even though you may not have taken any other action. If you select Cancel and Exit, newly discovered endpoints will not be added to your group regardless of match, and they will continue to be counted as Updated Endpoints.

Create Service Policy to Control Access to APIs

Perform the following to create service policies to control access to API groups based on API definitions and apply them to a load balancer.

Note: Rules can be configured and applied from within load balancers API EP monitoring view. See API Endpoint Discovery and Schema Learning guide for more info. Rules can also be applied to Shadow APIs. The discovered endpoints have an option to create protection rules and API rate limiting.

Step 1: Go to load balancers and start editing your load balancer.

Switch to Multi-Cloud App Connect service, and change to desired namespace.
Select Manage > Load Balancers > HTTP Load Balancers. A list of load balancers is presented.
Select ... > Manage Configuration for your load balancer.
Select Edit Configuration.

Note: The three types of APIs are distinguished only in Load Balancer API EP view.

Step 2: Start creating service policy.

In the Common Security Controls section, perform the following:

Step 2.1: Select existing service policy.

From the Service Policies drop-down menu, select Apply Specified Service Policies.
Select Configure or Edit Configuration link.
Select the existing policy from the Policies menu.
Click Apply.

Step 2.2: Create new service policy.

Select Add Item from the Policies menu.
Enter Name for the policy in the metadata section.
Select Allow from the Action drop-down menu.
In Advanced Match section, select Configure in API Group Matcher field.
Select an API group name string from the Exact values drop-down menu. Use Add Item to specify more than one group.
Select Apply to add the matcher.
Select Apply to add the new rule.
Create one more rule using the Add Item option in the rules section.
Enter a new name for this rule.
Set Deny as the Action and specify another API group to which you want to deny access (for example, all base URLs).
Select Apply.

Examples

Rule examples.

Note: This example creates a positive security model that only allows requests to operations that are specified in the file for each specified base URL. Requests to all operations (path plus the method) specified in files are allowed and requests to any unspecified operations under base URLs are denied. Requests sent to other URLs that do not match base URL are allowed.

Allow: The first rule allows the APIs.

Figure: API Matcher to Allow All Operational API URLs

Deny: The second rule denies the base URLs APIs.

Figure: Deny All Base URLs

The third rule allows all with the action as Allow. There is no need of API Matching for the third rule.

The sample order of service policy rules is as shown in the following image. This order is important as the rules are executed in the same order.

Figure: Order of Rules for Service Policy

Step 3: Complete creating service policy rules and policy.

Check that you created all rules per your requirements.
In Rules section, select Apply.
Select Continue to add the service policy to the load balancer.
Select Save and Exit to apply changes to load balancer configuration.
Refresh the page to view current API results when any changes are made in the Console. After APIs are learned, you can download the file, edit it if needed and import. Imported file will define API Inventory and groups, which can be used to create API protection rules.
