Configure HTTPD-Served Web Content Securely

Description

Running httpd inside a chroot jail is designed to isolate the web server process to a small section of the filesystem, limiting the damage if it is compromised. Versions of Apache greater than 2.2.10 (such as the one included with Red Hat Enterprise Linux 7) provide the ChrootDir directive. To run Apache inside a chroot jail in /chroot/apache, add the following line to /etc/httpd/conf/httpd.conf:

ChrootDir /chroot/apache

This necessitates placing all files required by httpd inside /chroot/apache , including httpd's binaries, modules, configuration files, and served web pages. The details of this configuration are beyond the scope of this guide. This may also require additional SELinux configuration.
