More than one Edge server must be deployed.
Medium Severity
<VulnDiscussion>To ensure hostile insiders are unable to easily commit DoS attacks and reduce the effectiveness of mail flow throughout the environment, a second Edge server is deployed to allow for multiple paths of mail flow both internally and externally into the environment. This prevents a single point-of-failure and allows for service to continue in the event of a DoS attack targeting one Edge role.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
