F5 Hybrid Security Architectures: Part 3 F5 XC API Protection and NGINX Ingress
Here in this example solution, we will be using DevSecOps practices to deploy an AWS Elastic Kubernetes Service (EKS) cluster running the Arcadia Finance test web application serviced by F5 NGINX Ingress Controller for Kubernetes. For protection, will provide API Discovery and Security with F5 Distributed Cloud's Web App and API Protection service. Introduction: For those of you following along with the F5 Hybrid Security Architectures series, welcome back! If this is your first foray into the series and would like some background, have a look at the intro article. This series is using theF5 Hybrid Security ArchitecturesGitHub repo and CI/CD platform to deploy F5 based hybrid security solutions based on DevSecOps principles. This repo is a community supported effort to provide not only a demo and workshop, but also a stepping stone for utilizing these practicesin your own F5 deployments. If you find any bugs or have any enhancement requests, open a issue or better yet contribute! API Security: APIs are an integral part of our daily routine, facilitating everything from critical to mundane tasks. From banking and ride-sharing apps to the weather updates we check before stepping out, APIs enable these functionalities. Given the sensitive nature of the data that can be exposed by unprotected APIs, the need for effective security cannot be stressed enough. With F5 Distributed Cloud Web App and API protection security teams can discover, inventory, and secure these critical APIs. Here in this example solution, we will be using DevSecOps practices to deploy an AWS Elastic Kubernetes Service (EKS) cluster running the Brewz test web application serviced by F5 NGINX Ingress Controller. To secure our application and APIs, we will deploy F5 Distributed Cloud's Web App and API Protection service. This will provide us API Discovery and Security as well as a traditional Web Application Firewall and Malicious User Detection. Distributed Cloud WAAP:Available for SaaS-based deploymentsand provides comprehensive security solutions designed to safeguard web applications and APIs from a wide range of cyber threats. This solution utilizes a distributed cloud architecture, which enables it to provide real-time protection and scale to meet the needs of large enterprises. NIGNX Ingress Controller for Kubernetes: A lightweight software solution that helps manage app connectivity at the edge of a Kubernetes cluster by directing requests to the appropriate services and pods. It provides advanced load balancing, routing, identity, and security, as well as montioring and observability features. XC WAAP + NGINX Ingress Controller Workflow GitHub Repo: F5 Hybrid Security Architectures Prerequisites: F5 Distributed Cloud Account (F5 XC) Create an F5 XC API certificate NGINX Ingress Controller license AWS Account- Due to the assets being created, free tier will not work.

EX:TF_CLOUD_WORKSPACE_XCwould be created with the value xc Your GitHub Actions Secrets should resemble the following: Setup Deployment Branch and Terraform Local Variables: Step 1: Check out a branch for the deploy workflow using the following naming convention xc-nic deployment branch: deploy-xcapi-nic Step 2:Rename infra/terraform.tfvars.examples to infra/terraform.tfvars and add the following data #Global project_prefix = "Your project identifier" resource_owner = "You" #AWS aws_region = "Your AWS region" ex: us-west-1 azs = "Your AWS availability zones" ex: ["us-west-1a", "us-west-1b"] #Assets nic = true nap = false bigip = false bigip-cis = false Step 3: Rename xc/terraform.tfvars.examples to xc/terraform.tfvars and add the following data #XC Global api_url = "https://.console.ves.volterra.io/api" xc_tenant = "Your XC Tenant Name" xc_namespace = "Your XC namespace" #XC LB app_domain = "Your App Domain" #XC WAF xc_waf_blocking = true #XC AI/ML Settings for MUD, APIP - NOTE: Only set if using AI/ML settings from the shared namespace xc_app_type = [] xc_multi_lb = false #XC API Protection and Discovery xc_api_disc = true xc_api_pro = true xc_api_spec = ["Path to uploaded API spec"] *See below screen shot for how to obtain this value. #XC Bot Defense xc_bot_def = false #XC DDoS xc_ddos = false #XC Malicious User Detection xc_mud = true For Path to API Spec navigate to Manage->Files->Swagger Files, click the three dots next to your OAS, and choose "Copy Latest Version's URL". Paste this into the xc_api_spec in the xc/terraform.tfvars. Step 4: Modify line 16 in the .gitignore and comment out the *.tfvars line with # and save the file Step 5: Commit your changes Deployment: Step 1: Push your deploy branch to the forked repo Step 2:Back in GitHub, navigate to the Actions tab of your forked repo and monitor your build Step 3: Once the pipeline completes, verify your assets were deployed to AWS and F5 XC Step 4:Check your Terraform Outputs for XC and verify your app is available by navigating to the FQDN API Discovery andSecurity Dashboards: After leaving the Brewz test app deployed for a while we can start to see the API graph form. The F5 XC WAAP platform learns the schema structure of the API by analyzing sampled request data, then reverse-engineering the schema to generates an OpenAPI spec. The platform validates what is deploy versus what is discovered and tags any Shadow APIs that are found. We can also check the dashboards for any attacks that may have occurred while we were waiting for discovery to finish. The internet being what it is, it didn't take long for the platform to protect us against some attacks. Deployment Teardown: Step 1:From your deployment branch check out a branch for the destroy workflow using the following naming convention xc-nic destroy branch: destroy-xcapi-nic Step 2: Push your destroy branch to the forked repo Step 3: Back in GitHub, navigate to the Actions tab of your forked repo and monitor your build Step 4:Once the pipeline completes, verify your assets were destroyed Conclusion: In this article we have shown how to utilize the F5 Hybrid Security Architectures GitHub repo and CI/CD pipeline to deploy a tiered security architecture utilizing F5 XC WAAP and NGINX Ingress Controller to protect a test API running in AWS EKS. While the code and security policies deployed are generic and not inclusive of all use-cases, they can be used as a steppingstone for deploying F5 based hybrid architectures in your own environments. Workloads are increasingly deployed across multiple diverse environments and application architectures. Organizations need the ability to protect their essential applications regardless of deployment or architecture circumstances. Equally important is the need to deploy these protections with the same flexibility and speed as the apps they protect. With the F5 WAF portfolio, coupled with DevSecOps principles, organizations can deploy and maintain industry-leading security without sacrificing the time to value of their applications. Not only can Edge and Shift Left principles exist together, but they can also work in harmony to provide a more effective security solution.

Here in this example solution, we will be using Terraform to deploy an AWS Elastic Kubernetes Service cluster running the Arcadia Finance test web application serviced by F5 NGINX Kubernetes Ingress Controller and protected by NGINX App Protect WAF. We will supplement this with F5 Distributed Cloud Web App and API Protection to provide complimentary security at the edge. Everything will be tied together using GitHub Actions for CI/CD and Terraform Cloud to maintain state.F5 Hybrid Security Architectures: One WAF Engine, Total Flexibility (Intro)
Layered security, we have been told for years that the most effective security strategy is composed of multiple, loosely coupled or independent layers of security controls. A WAF fits snuggly into the technical security controls area and has long been known as an essential piece of application security. What if we take this further and apply the layered approach directly to our WAF deployment? The F5 Hybrid Security Architectures explores this approach utilizing F5's best in class WAF products.Minimizing Security Complexity: Managing Distributed WAF Policies
In this article and demo, we'll explore a few best practices and tools available to help organizations maintain robust security postures acrosstheir entire WAF infrastructure, and how embracingmodern approaches like DevSecOps and the F5 Policy Supervisor and Conversion tools can help overcome the challengesof managing security policies at scale.F5 Hybrid Security Architectures (Part 1 - F5's Distributed Cloud WAF and BIG-IP Advanced WAF)
