selinux-nginx

SELinux Nginx policy for Debian.

Modified from http://sourceforge.net/projects/selinuxnginx/

This policy has not been thoroughly tested or peer reviewed. Use at your own risk. However, it should be substantially better than running Nginx without any policy.

Other Nginx policies worth evaluating...

• https://github.com/heinoja9/selinux/tree/master/nginx_fe_local
  • RHEL/CentOS but easily modified for Debian

Install

apt-get install selinux-policy-dev
git clone https://github.com/simple10/selinux-nginx.git
cd selinux-nginx/nginx
make
semodule -i nginx.pp

# Relabel the filesystem
touch /.autorelabel
reboot

# Make sure nginx is running as nginx_exec_t
ls -Z /usr/sbin/nginx
# system_u:object_r:nginx_exec_t:SystemLow /usr/sbin/nginx

# Check the audit logs to see if nginx is being denied
audit2why -al
# No output is good. If there are denials, modify the policy as necessary.
