F5 Distributed Cloud Hybrid Security Architecture Deployments

Overview

Examples of hybrid security deployments utilizing F5 Distributed Cloud WAAP in conjunction with the F5 product portfolio. For more information on the project, please see the following article series F5 Hybrid Security Architectures: One WAF Engine, Total Flexibility

Getting Started

Prerequisites

Assets

  • xc: F5 Distributed Cloud WAAP
  • nap: NGINX Ingress Controller for Kubernetes with NGINX App Protect (WAF and API Protection)
  • bigip-base: F5 BIG-IP Base
  • bigip-awaf: F5 BIG-IP Advanced WAF
  • bigip-cis: F5 Big-IP Container Ingress Services
  • infra: AWS Infrastructure (VPC, IGW, etc.)
  • eks: AWS Elastic Kubernetes Service
  • brewz: Brews Microservice
  • arcadia: Arcadia Finance test web application and API
  • juiceshop: OWASP Juice Shop test web application

Tools

  • Cloud Provider: AWS
  • IAC: Terraform
  • IAC State: Terraform Cloud
  • CI/CD: GitHub Actions

Terraform Cloud

  • Workspaces: Create a CLI or API workspace for each asset in the workflow chosen. Check your work-flow article for more details

    Workflow Assets/Workspaces
    xc-bigip infra, bigip-base, bigip-awaf, juiceshop, xc
    xc-nap infra, eks, nap, arcadia, xc
    xc-nic-api infra, eks, nic, brewz, xc
    xc-bigip+bot infra, bigip-base, bigip-awaf, juiceshop, xc
    xcbn-cis infra, bigip-base, bigip-cis, eks, nic, brewz, xc

  • Workspace Sharing: Under the settings for each Workspace, set the Remote state sharing to share with each Workspace created.

  • Variable Set: Create a Variable Set with the following values:

    Name Type Description
    AWS_ACCESS_KEY_ID Environment Your AWS Access Key ID
    AWS_SECRET_ACCESS_KEY Environment Your AWS Secret Access Key
    AWS_SESSION_TOKEN Environment Your AWS Session Token
    NGINX_JWT Environment Your NGINX JSON Web Token value associated with your NGINX license.
    VOLT_API_P12_FILE Environment Your F5XC API certificate. Set this to api.p12
    VES_P12_PASSWORD Environment Set this to the password you supplied when creating your F5 XC API certificate
    ssh_key Terraform Your ssh key for accessing the created BIG-IP and compute assets
    admin_src_addr Terraform The source address and subnet in CIDR format of your administrative workstation
    tf_cloud_organization Terraform Your Terraform Cloud Organization name

GitHub

  • Fork and Clone Repo. Navigate to Actions tab and enable it.

  • Actions Secrets: Create the following GitHub Actions secrets in your forked repo

    • P12: The linux base64 encoded F5XC API certificate
    • TF_API_TOKEN: Your Terraform Cloud API token
    • TF_CLOUD_ORGANIZATION: Your Terraform Cloud Organization name
    • TF_CLOUD_WORKSPACE_<Workspace Name>: Create for each workspace in your workflow
      • EX: TF_CLOUD_WORKSPACE_BIGIP_BASE would be created with the value bigip-base

Workflow Runs

STEP 1: Check out a branch for the workflow you wish to run using the following naming convention.

DEPLOY

Workflow Branch Name
xc-bigip deploy-xc-bigip
xc-nap deploy-xc-nap
xcapi-nic deploy-xcapi-nic
xc-bigip+bot deploy-xc-bigip
xcbn-cis deploy-xcbn-cis

DESTROY

Workflow Branch Name
xc-bigip destroy-xc-bigip
xc-nap destroy-xc-nap
xcapi-nic destroy-xcapi-nic
xc-bigip+bot destroy-xc-bigip
xcbn-cis destroy-xcbn-cis

STEP 2: Rename infra/terraform.tfvars.examples to infra/terraform.tfvars and add the following data:

  • project_prefix = "Your project identifier name in lower case letters only - this will be applied as a prefix to all assets"
  • resource_owner = "Your-name"
  • aws_region = "AWS Region" ex. us-east-1
  • azs = ["us-east-1a", "us-east1b"] - Change to Correct Availability Zones based on selected Region
  • Also update assets boolean value as per your work-flows

STEP 3: Depending on your work-flow, rename and update related .tfvars. For example in xc-bigip work-flow, update bigip/terraform.tfvars.examples to bigip/terraform.tfvars and add the following data:

  • f5_ami_search_name = "F5 BIGIP-16.1.3* PAYG-Adv WAF Plus 25Mbps*" - You must be subscribed to the AMI in the AWS Marketplace
  • aws_secretmanager_auth = false
  • create_awaf_config = true
  • awaf_config_payload = "awaf-config.json"

Step 3: Rename xc/terraform.tfvars.examples to xc/terraform.tfvars and add the following data:

  • api_url = "Your F5XC tenant"
  • xc_tenant = "Your tenant id available in F5 XC Administration section Tenant Overview menu"
  • xc_namespace = "The existing XC namespace where you want to deploy resources"
  • app_domain = "the FQDN of your app (cert will be autogenerated)"
  • xc_waf_blocking = "Set to true to enable blocking"
  • Also update assets boolean value as per your work-flow based on the values in the tfvars example.

STEP 5: Commit and push your build branch to your forked repo

  • Build will run and can be monitored in the GitHub Actions tab and TF Cloud console

STEP 6: Once the pipeline completes, verify your assets were deployed or destroyed based on your workflow. From F5 XC console, you can check if the F5 XC load balancer has come to active. NOTE: The autocert process takes time. It may be 5 to 10 minutes before Let's Encrypt has provided the cert.
