Using NGINX App Protect WAF with NGINX Controller

Take the steps in this guide to deploy NGINX App Protect WAF as a datapath instance for use with NGINX Controller.

Note: Refer to the NGINX Controller Technical Specifications guide to find out which distributions are supported for use with NGINX Controller and NGINX Controller Agent.

Setup

Before proceeding, you should review the Prerequisites, Platform Security Considerations and User Permissions sections of the NGINX App Protect WAF Admin Guide.

Install NGINX App Protect WAF

Note: If a version of NGINX App Protect WAF prior to 3.6 is required, please contact the NGINX Sales team to assist with this configuration.

If you already have NGINX packages in your system, back up your configs and logs:

sudo cp -a /etc/nginx /etc/nginx-plus-backup
sudo cp -a /var/log/nginx /var/log/nginx-plus-backup

Create the /etc/ssl/nginx/ directory:
```
sudo mkdir -p /etc/ssl/nginx
```
Log in to the NGINX Customer Portal and download the following two files:
```
nginx-repo.key
nginx-repo.crt
```
See Also: You can use the NGINX Controller REST API to download the key and cert files.
Copy the above two files to the CentOS server’s /etc/ssl/nginx/ directory. Use an SCP client or another secure file transfer tool to perform this task.

Install prerequisite packages:

sudo yum install ca-certificates epel-release wget

Remove any previously downloaded NGINX Plus repository file from /etc/yum.repos.d:
```
sudo rm /etc/yum.repos.d/nginx-plus-*.repo
```
Add NGINX Plus repository by downloading the file nginx-plus-7.4.repo to /etc/yum.repos.d:
```
sudo wget -P /etc/yum.repos.d https://cs.nginx.com/static/files/nginx-plus-7.4.repo
```
Add NGINX App Protect WAF repository by downloading the file app-protect-7.repo to /etc/yum.repos.d:
```
sudo wget -P /etc/yum.repos.d https://cs.nginx.com/static/files/app-protect-7.repo
```
If NGINX Plus or NGINX App Protect WAF was previously installed on the system, clean up package manager cache information:
```
sudo yum clean all
```
Install the latest NGINX App Protect WAF package.

See Also: Please refer to NGINX App Protect Compatibility Matrix for specific version compatibility.

If you wish to install a specific version, please replace app-protect with the target version, for example app-protect-25+3.671.0:
```
sudo yum install app-protect
```
Check the NGINX binary version to ensure that you have NGINX Plus installed correctly:
```
sudo nginx -v
```
Configure SELinux as appropriate per your organization’s security policies. NGINX App Protect WAF applies the prebuilt SELinux policy module during the installation. If you encounter any issues, check the Troubleshooting Guide.

Note: NGINX Controller has specific requirements regarding SELinux configuration.
Start the NGINX service:
```
sudo systemctl start nginx
```
Start the bd_agent service (for Controller ADC Agent 3.20.1 or Controller APIM Agent 3.19.2 only)

If you plan to use this instance with Controller ADC Agent 3.20.1 or Controller APIM Agent 3.19.2, you need to start the bd_agent:
```
/bin/su -s /bin/bash -c '/opt/app_protect/bin/bd_agent &' nginx
```
Verify NGINX Plus and BD processes are running:
```
ps -ef | grep nginx
ps -ef | grep bd
```
Note: If you plan to use this instance with Controller ADC Agent 3.20.1 or Controller APIM Agent 3.19.2, also verify that bd_agent is running:
```
ps -ef | grep bd_agent
```
To upgrade your signature package to the latest version and obtain the best protection, refer to Updating App Protect Attack Signatures.

If you already have NGINX packages in your system, back up your configs and logs:

sudo cp -a /etc/nginx /etc/nginx-plus-backup
sudo cp -a /var/log/nginx /var/log/nginx-plus-backup

Create the /etc/ssl/nginx/ directory:
```
sudo mkdir -p /etc/ssl/nginx
```
Log in to the NGINX Customer Portal and download the following two files:
```
nginx-repo.key
nginx-repo.crt
```
Copy the above two files to the RHEL server’s /etc/ssl/nginx/ directory. Use an SCP client or another secure file transfer tool to perform this task.
Install prerequisite packages:
```
sudo yum install ca-certificates wget
```
Remove any previously downloaded NGINX Plus repository file from /etc/yum.repos.d:
```
sudo rm /etc/yum.repos.d/nginx-plus-*.repo
```
Add NGINX Plus repository by downloading the file nginx-plus-7.4.repo to /etc/yum.repos.d:
```
sudo wget -P /etc/yum.repos.d https://cs.nginx.com/static/files/nginx-plus-7.4.repo
```
Add NGINX App Protect WAF repository by downloading the file app-protect-7.repo to /etc/yum.repos.d:
```
sudo wget -P /etc/yum.repos.d https://cs.nginx.com/static/files/app-protect-7.repo
```

Enable Yum repositories to pull App Protect dependencies:

Download the file dependencies.repo to /etc/yum.repos.d:

sudo wget -P /etc/yum.repos.d https://cs.nginx.com/static/files/dependencies.repo

If you have a RHEL subscription:

sudo yum-config-manager --enable rhui-REGION-rhel-server-optional rhui-REGION-rhel-server-releases rhel-7-server-optional-rpms

If you don’t have a RHEL subscription, you can pull the dependencies from the CentOS repository.

Create a new repository, centos.repo, in /etc/yum.repos.d/ with the content:

[centos]
name=CentOS-7
baseurl=http://ftp.heanet.ie/pub/centos/7/os/x86_64/
enabled=1
gpgcheck=1
gpgkey=http://ftp.heanet.ie/pub/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7

```
ps -ef | grep nginx
ps -ef | grep bd
```
Note: If you plan to use this instance with Controller ADC Agent 3.20.1 or Controller APIM Agent 3.19.2, also verify that bd_agent is running:
```
ps -ef | grep bd_agent
```
To upgrade your signature package to the latest version and obtain the best protection, refer to Updating App Protect Attack Signatures.

Note: As of NGINX Plus R24, support for Debian 9 is no longer available. As a consequence, NGINX App Protect WAF 3.1 is the final version available for this operating system version.

To upgrade your signature package to the latest version and obtain the best protection, refer to Updating App Protect Attack Signatures.

Note: Ubuntu 20.04 activates AppArmor by default, but NGINX App Protect WAF will run in unconfined mode after being installed as it is shipped with no AppArmor profile. To benefit from AppArmor access control capabilities for NGINX App Protect WAF, you will have to write your own AppArmor profile for NGINX App Protect WAF executables found in /opt/app_protect/bin such that it best suits your environment.

Using NGINX App Protect WAF with NGINX Controller isn’t supported on Amazon Linux 2 LTS.

Using NGINX App Protect WAF with NGINX Controller isn’t supported on Alpine.

Add NGINX App Protect WAF to NGINX Controller

If this NGINX Plus instance is already managed by Controller, restart the Agent after NGINX App Protect WAF is installed.

Otherwise, complete the tasks in the NGINX Controller Add an NGINX App Protect WAF Instance guide.

Use NGINX App Protect WAF with NGINX Controller

Note: When configuring NGINX App Protect WAF as a datapath instance for NGINX Controller, you should not modify the nginx.conf file. The nginx.conf file will be automatically updated when enabling WAF on a Component in NGINX Controller.
