EX13-CA-000140 - Exchange software must be installed on a separate partition from the OS.


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 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.


Update the EDSP.

Install Exchange on a dedicated application directory or partition separate than that of the OS.
