EX16-MB-000620 - The Exchange Email application must not share a partition with another application.
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 with the location of where Exchange is installed. Install Exchange on a dedicated application directory or partition separate than that of the operating system.
