# Ensure Other Write Access on Apache Directories and Files Is Restricted

## Description

The permission on the Apache directories should be `rwxr-xr-x` (755) and the file permissions should be similar, except not executable unless appropriate. This applies to all the Apache software directories and files installed, with the possible exception in some cases that a group with write access for the Apache web document root (`$APACHE_PREFIX/htdocs`) may be needed to allow web content to be updated. In addition, the `/bin` directory and executables should be set to not be readable by other.

## Rationale

None of the Apache files and directories, including the Web document root, should allow other write access. Other write access is likely to be very useful for unauthorized modification of web content, configuration files, and software.

## Impact

None documented

## Audit Procedure

Verify that there are no files or directories in the Apache directory with other write access, excluding symbolic links:

```
# find -L $APACHE_PREFIX \! -type l -perm /o=w -ls
```

## Remediation

Perform the following to remove other write access on the `$APACHE_PREFIX` directories:

```
# chmod -R o-w $APACHE_PREFIX
```

## Default Value

The default permissions are mostly `rwxr-xr-x`, except for some files which have group or other permissions that are affected by the umask of the user performing the build.
