Exchange antimalware agent must be enabled and configured.
An XCCDF Rule
Description
<VulnDiscussion>Microsoft Exchange 2019 offers built-in antimalware protection for messages going through the transport pipeline. When enabled, the default settings are configured to automatically update. Exchange's built-in Malware Agent is not designed to address all malicious code protection workloads. This workload is best handled by third-party antivirus and intrusion prevention software. Sites must use an approved DOD scanner. Exchange Malware software has a limited scanning capability and does not scan files that are downloaded, opened, or executed.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
