It enables you to configure a set of rules called a web access control list web ACL that allow, block, or count web requests based on customizable web security rules and conditions that you define.

These could affect API availability and performance, compromise security, or consume excessive resources. For example, you can create rules to allow or block requests from specified IP address ranges, requests from CIDR blocks, requests that originate from a specific country or region, requests that contain malicious SQL code, or requests that contain malicious script.

You can also create rules that match a specified string or a regular expression pattern in HTTP headers, method, query string, URI, and the request body limited to the first 8 KB. Additionally, you can create rules to block attacks from specific user agents, bad bots, and content scrapers. For example, you can use rate-based rules to specify the number of web requests that are allowed by each client IP in a trailing, continuously updated, 5-minute period.

There are even templates specific to WAF deployment you can use. I deployed by using the 2 NIC template because I prefer to separate the management interface from the traffic interface. I then added a secondary IP to the traffic network interface and an elastic IP for it. There are two deployment scenarios, in front of the API Gateway or behind. Here are the traffic flows for each. For example, it could be a web server running in EC2 or it could be serverless code running in Lambda.

The F5 in front is probably the optimal choice for most applications because it could block requests from reaching the API Gateway service, which has a cost associated with it per request. It also provides significant flexibility to have AWS calling other integrated services with ease which could be Lambda, a web server, or anything else.

One for the management interface, one for the traffic interface, and a third that you added for the virtual server secondary IP. The guide below assumes you will deploy in front of the API Gateway, which will require a rewrite of the URL and this is shown as the rewrite profile.

Of course! You can download and import this collection and environment from GitHub herefill in the required variables, and it will do all the work for you in a few seconds. Open up the environment and set the variables noted below. Also, you then use 0. Your monitor and pool will change as well. This is only the beginning. You will use the ephemeral DNS name based nodes for this solution. Anything not listed here will be left default. Now you have a functioning reverse proxy for your API.

First, create a new WAF policy. If not, you can select a Rapid Deployment Policy, Fundamental, or other as appropriate. Now you can add the WAF policy and the appropriate logging profile to your virtual server.

The API protection you deploy with this solution is a basic generic policy and is setup in transparent mode. It will start out with a large set of signatures from the API Security template.

Nice article, Graham! I was thinking that ASM really needs tools to be able to defend against small scale API automation attacks by throttling or rejecting bad actors.

Using AWS WAF to protect your APIs

ASM has native bot detection tools, but most of them rely on classic device detection which uses Javascript insertion, which isn't an option for an APIor provide protection for larger-scale attacks such as DDoS. It seems like this can really only be accomplished right now with an iRule. Something like this built right into ASM would be great not only for on-prem but also for cloud WAF deployments such as you feature in your article.

First, we need to create a few objects.Your apps and APIs are likely at risk, and increased mobility and the adoption of multi-cloud has only added to your attack surface. This demands holistic applications and API security for both monolithic and microservices-based applications.

To achieve this strong security posture across all environments, you need an application delivery solution that shares a common code base. This lets you implement consistent security policies across all your applications for comprehensive protection. Securing your applications and APIs in a multi-cloud infrastructure is both crucial and complex.

To prevent cyberattacks from taking advantage of your extended attack surface, you need to apply consistent security policies whenever you deploy any application.

Because all Citrix ADC form factors share a single code base, IT can achieve a consistent security posture for all applications and APIs across multi-cloud environments. This reduces the complexity and vulnerability of your entire infrastructure, from monolithic to microservices-based apps. This is why Citrix ADC provides comprehensive and integrated Layer 3—7 security, including a web application firewall WAF to protect your applications.

Identify and mitigate malicious bots with regularly updated bot signatures, behavior-based detection, and rate limits that prevent your public infrastructure from being overwhelmed.

For example, the Amazon. Since the online store uses the Microservice architecture pattern the product details data is spread over multiple services. For example. Consequently, the code that displays the product details needs to fetch information from all of these services. The granularity of APIs provided by microservices is often different than what a client needs. Microservices typically provide fine-grained APIs, which means that clients need to interact with multiple services.

For example, as described above, a client needing the details for a product needs to fetch data from numerous services. Different clients need different data. For example, the desktop browser version of a product details page desktop is typically more elaborate then the mobile version. Network performance is different for different types of clients.

For example, a mobile network is typically much slower and has much higher latency than a non-mobile network. This means that a native mobile client uses a network that has very difference performance characteristics than a LAN used by a server-side web application.

The server-side web application can make multiple requests to backend services without impacting the user experience where as a mobile client can only make a few. Implement an API gateway that is the single entry point for all clients. The API gateway handles requests in one of two ways. It handles other requests by fanning out to multiple services. The API gateway might also implement security, e.

A variation of this pattern is the Backends for frontends pattern. It defines a separate API gateway for each kind of client. In this example, there are three kinds of clients: web application, mobile application, and external 3rd party application.

There are three different API gateways. Each one is provides an API for its client.

Resource policies let you create resource-based policies to allow or deny access to your APIs and methods from specified source IP addresses or VPC endpoints. IAM roles and policies can be used for controlling who can create and manage your APIs, as well as who can invoke them. Lambda authorizers are Lambda functions that control access to REST API methods using bearer token authentication—as well as information described by headers, paths, query strings, stage variables, or context variables request parameters.

You can use the following mechanisms for performing other tasks related to access control:. For more information, see Generate and configure an SSL certificate for backend authentication.

Document Conventions. Set up method using the console. Use API Gateway resource policies.Go to the Azure portal to register your application. Search for and select APP registrations. When the Register an application page appears, enter your application's registration information:. On the app Overview page, find the Application client ID value and record it for later. Record this value for later. Select the Add a scope button to display the Add a scope page.

Then create a new scope that's supported by the API for example, Files. Finally, select the Add scope button to create the scope. Repeat this step to add all scopes supported by your API. Under Add a client secretprovide a Description. Choose when the key should expire, and select Add.

Now that you have registered two applications to represent the API and the Developer Console, you need to grant permissions to allow the client-app to call the backend-app.

Go to the Azure portal to grant permissions to your client application. Choose your client app. Then in the list of pages for the app, select API permissions. Under Delegated Permissionsselect the appropriate permissions to your backend-app, then select Add permissions. At this point, you have created your applications in Azure AD, and have granted proper permissions to allow the client-app to call the backend-app. In this example, the Developer Console is the client-app.

The following steps describe how to enable OAuth 2. The Client registration page URL points to a page that users can use to create and configure their own accounts for OAuth 2. In this example, users do not create and configure their own accounts, so you use a placeholder instead.

Retrieve these values from the Endpoints page in your Azure AD tenant. Browse to the App registrations page again, and select Endpoints. Copy the OAuth 2. You can use either v1 or v2 endpoints. However, depending on which version you choose, the below step will be different.

We recommend using v2 endpoints.

If you use v1 endpoints, add a body parameter named resource. For the value of this parameter, use Application ID of the back-end app. If you use v2 endpoints, use the scope you created for the backend-app in the Default scope field. Also, make sure to set the value for the accessTokenAcceptedVersion property to 2 in your application manifest.

Make a note of this URL.The tutorial shows how to transform your API so it does not reveal a private backend info. For example, you might want to hide the info about technology stack that is running on the backend. For example, you may want to limit a number of calls the API is called so it is not overused by developers. For more information, see API Management policies. This section shows how to hide the HTTP headers that you do not want to show to your users.

Pattern: API Gateway / Backends for Frontends

In this example, the following headers get deleted in the HTTP response:. For example:. This section shows how to add protection for your backend API by configuring rate limits. In this example, the limit is set to 3 calls per 15 seconds for each subscription Id.
