3.9 Ensure the Pid File Is Secured

Profile Applicability

Level 1

Description

The PidFile directive sets the file path to the process ID file to which the server records the process id of the server, which is useful for sending a signal to the server process or for checking on the health of the process.

Rationale

If the PidFile is placed in a writable directory, other accounts could create a denial of service attack and prevent the server from starting by creating a PID file with the same name.

Audit

Find the directory in which the PidFile would be created. The default value is the ServerRoot/logs directory.
Verify that the process ID file directory is not a directory within the Apache DocumentRoot
Verify that the ownership and group of the directory is root:root (or the user under which Apache initially starts up if not root).
Verify the permissions on the directory are only writable by root (or the startup user if not root).

Remediation

Find the directory in which the PidFile would be created. The default value is the ServerRoot/logs directory.
Modify the directory if the PidFile is in a directory within the Apache DocumentRoot.
Change the ownership and group to be root:root, if not already.
Change the permissions so that the directory is only writable by root, or the user under which Apache initially starts up (default is root).

Default Value

The default process ID file is logs/httpd.pid.
