NOTE: Administrative shares are not exempt from this requirement.
NOTE: In the case of a storage area network or file storage network, where partitions on the storage device are dedicated to front end / back end web services, the additional partitions will be mapped to the correct file storage network partition in the web server configuration. This can apply to both web content and web scripts.
NOTE: The presence of operating system shares on the web server is not an issue as long as the shares are not part of the web content directories. The use of shares to move content from one environment to another is permitted if the following conditions are met: they are approved by the IAM/IAO; the shares are restricted to only allow administrators write access; the use of the shares does not bypass the sites approval process for posting new content to the web server; and developers are only permitted read access to these directories.
