Ensure the Group Is Set Correctly on Apache Directories and Files

Description

The Apache directories and files should be set to have a group of root (or a root equivalent group). This applies to all 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.

Impact

None documented

Audit Procedure

Verify that there are no 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 the group on the $APACHE_PREFIX directories, such as /usr/local/apache2:

$ chgrp -R root $APACHE_PREFIX

Default Value

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