Ensure 'Turn on e-mail scanning' is set to 'Enabled'

보통레벨 1자동defender

설명

This policy setting configures e-mail scanning. When e-mail scanning is enabled, the engine will parse the mailbox and mail files, according to their specific format, to analyze the mail bodies and attachments. Several e-mail formats are currently supported, for example: pst (Outlook), dbx, mbx, mime (Outlook Express), binhex (Mac). The recommended state for this setting is: Enabled. Rationale: All emails should be scanned by an antivirus solution such as Microsoft Defender Antivirus, as email attachments are a commonly used attack vector to infiltrate computers with malicious software. Audit reads the Group Policy registry value and prints 'compliant', 'unset' (policy not configured, reported as FAIL) or the non-compliant value. Registry value: HKLM\SOFTWARE\Policies\Microsoft\Windows Defender\Scan:DisableEmailScanning (REG_DWORD); compliant when it is 0. Remediation writes 0 locally; in a domain set it through the ADMX so Group Policy does not revert it.
