Does ASL work with Nginx?
Yes. Nginx is protected through the ASL 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:
Note: Libmodsecurity 3.0 for nginx is currently in an "Alpha" state, and is not feature complete.
How to install the T-WAF
As root, run this command:
yum install asl-waf-module
How to configure the T-WAF for nginx
Step 1) Log into ASL.
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 for Libmodsecurity 3.0
Note: This requires nginx-plus from nginx.com, libmodsecurity 3.0 is not feature complete at this time.
1) Install nginx-plus-module-modsecurity from the nginx-plus repo
yum intsall nginx-plus-module-modsecurity
2) enable modsecurity in /etc/nginx/nginx.conf
3) extract the archive and copy the contents to the rule and config directories:
mkdir -p /etc/httpd/modsecurity.d/
cp rules/* /etc/httpd/modsecurity.d/
cp conf/tortix_waf.conf /etc/httpd/modsecurity.d/
4) Configure rule classes to activate in 00_mod_security.conf, and copy to nginx
cp conf/00_mod_security.conf /etc/nginx/conf.d/
5) Restart nginx
service nginx restart
