Nginx

Does AED work with Nginx?

  • Yes. Nginx is protected through the AED T-WAF module.

Note

Do not use the embedded modsecurity module for nginx. The opensource modsecurity module for nginx, although advertised as “stable” by the modsecurity.org website, is very unstable and unreliable and should not be used at this time. Please see the github website for details on bugs in the nginx modsecurity module: https://github.com/SpiderLabs/ModSecurity/issues


How to install the T-WAF

  • Run the following command as root:

    yum install asl-waf-module
    

How to configure the T-WAF for Nginx

Step 1) Log into AED.

Step 2) Click on the “Configuration” tab.

Step 3) Click on the “WAF” tab and select “WAF configuration”.

Step 4) Click the “Add” button.

Step 5) Select “Local Web Server” from the “Add protection for” drop down.

Step 6) Select the port that Nginx runs on. Normally this is port 80.

Optional Step 7) Check the SSL box (if you want to protect the SSL service(s) provided by Nginx)

Enter the file system path to your SSL certificate, and SSL key in the “Path to SSL Certificate” and “Path to SSL Key file” boxes.

Step 8) Click Save

Note

Nginx does not support the WAF in embedded mode.


NGINX with Libmodsecurity 3.0

Note

This requires nginx-plus from nginx.com, libmodsecurity 3.0 is not feature complete at this time.

Step 1) Install nginx-plus-module-modsecurity from the nginx-plus repo by running the following command:

yum install nginx nginx-module-modsecurity

Step 2) Enable modsecurity in /etc/nginx/nginx.conf by adding the following line:

load_module modules/ngx_http_modsecurity_module.so;

Step 3) Extract the archive and copy the contents to the rule and config directories by running the following commands:

tar xvf nginx-waf-201709121114.tar.gz
mkdir -p /etc/httpd/modsecurity.d/
cp rules/* /etc/httpd/modsecurity.d/
cp rules/conf/tortix_waf.conf /etc/httpd/modsecurity.d/

Step 4) Configure rule classes to activate in 00_mod_security.conf, and copy to nginx by running the following commands:

cp rules/conf/00_mod_security.conf /etc/nginx/conf.d/

Step 5) Restart Nginx by running the following command:

service nginx restart
