EX16-MB-000200 - Exchange Mailbox databases must reside on a dedicated partition.

Information

In the same way that added security layers can provide a cumulative positive effect on security posture, multiple applications can provide a cumulative negative effect. A vulnerability and subsequent exploit to one application can lead to an exploit of other applications sharing the same security context. For example, an exploit to a web server process that leads to unauthorized administrative access to the host system can most likely lead to a compromise of all applications hosted by the same system.

Email services should be installed to a discrete set of directories on a partition that does not host other applications. Email services should never be installed on a Domain Controller/Directory Services server.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

Update the EDSP to specify the location where the Exchange Mailbox databases reside or verify that this information is documented by the organization.

Configure the mailbox databases on a dedicated partition.
