The macOS system must disable FileVault automatic log on.
An XCCDF Rule
Description
<VulnDiscussion>If FileVault is enabled, automatic log on must be disabled, so that both FileVault and login window authentication are required. The default behavior of macOS when FileVault is enabled is to automatically log on to the computer once successfully passing user's FileVault credentials. Note: DisableFDEAutoLogin does not have to be set on Apple Silicon-based macOS systems that are smartcard enforced, as smartcards are available at preboot.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
