A DoD-approved third-party Exchange-aware malicious code protection application must be implemented.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-80621	EX16-ED-003020	SV-95331r1_rule		Medium

Description
Malicious code protection mechanisms include, but are not limited, to, anti-virus and malware detection software. In order to minimize potential negative impact to the organization that can be caused by malicious code, it is imperative that malicious code is identified and eradicated. Malicious code includes viruses, worms, trojan horses, and spyware. It is not enough to simply have the software installed; this software must periodically scan the system to search for malware on an organization-defined frequency. Exchange's built-in Malware Agent is not designed to address all malicious code protection workloads. This workload is best handled by third-party anti-virus and intrusion prevention software. Site must utilize an approved DoD scanner. Exchange Malware software has a limited scanning capability and does not scan files that are downloaded, opened, or executed.

Check Text ( C-80353r1_chk )
Site must utilize an approved DoD third-party malicious code scanner. Consult with System Administrator to demonstrate the application being used to provide malicious code protection in the Exchange implementation. If System Administrator is unable to demonstrate a third-party malicious code protection application, this is a finding. If System Administrator is unaware of a third-party malicious code protection application, this is a finding.
