3.5 Ensure the Group Is Set Correctly on Apache Directories and Files

Profile Applicability

  • Level 1

Description

The Apache directories and files should be set to have a group Id of root, (or a root equivalent) group. This applies to all of the Apache software directories and files installed. The only expected exception is that the Apache web document root ($APACHE_PREFIX/htdocs) is likely to need a designated group to allow web content to be updated (such as webupdate) through a change management process.

Rationale

Securing Apache files and directories will reduce the probability of unauthorized modifications to those resources.

Audit

Identify files in the Apache directories other than htdocs with a group other than root:

# find $APACHE_PREFIX -path $APACHE_PREFIX/htdocs -prune -o \! -group root -ls

Remediation

Perform the following:

Set ownership on the $APACHE_PREFIX directories such as /usr/local/apache2:

# chgrp -R root $APACHE_PREFIX

Default Value

Default ownership and group is a mixture of the user:group that built the software and root:root.
