To meet the requirement of ensuring that emails received by company users that contain URLs do not make them susceptible to data loss from accessing malicious or undesired external content sources, the administrator must configure two features on Cisco Secure Email Gateway: antispam scanning and URL filtering. Antispam scanning can block or quarantine messages that are identified as spam based on various criteria, such as sender reputation, message content, and message headers. URL filtering can rewrite or defang URLs in messages that are associated with malicious or undesirable websites, such as phishing, malware, adult, or gambling sites. Reference: [Cisco Secure Email Gateway Administrator Guide - Configuring Antispam Scanning] and [Cisco Secure Email Gateway Administrator Guide - Configuring URL Filtering]

To combat backscatter, which is a type of spam that consists of bounce messages sent to forged sender addresses, the administrator must enable the Bounce Verification feature under Security Settings. This feature allows the appliance to verify whether a bounce message is legitimate or not by checking if the original message was sent from the appliance. If not, the bounce message is considered as backscatter and can be dropped or quarantined. Reference: [Cisco Secure Email Gateway Administrator Guide - Configuring Bounce Verification]

According to the Cisco Secure Email Threat Defense User Guide, the No Authentication option is only available if you are using a Cisco Secure Email Gateway (SEG) as your message source. This option allows visibility only, no remediation1.

The other options are not valid because:

A. Basic Authentication is not a visibility and remediation mode for Cisco Secure Email Threat Defense. It is a method of authenticating users with a username and password2.

C. Microsoft 365 Authentication is a visibility and remediation mode that allows you to use Microsoft 365 credentials to access Cisco Secure Email Threat Defense. It has two sub-options: Read/Write and Read. This mode is available for both Microsoft 365 and Gateway message sources1.

D. Cisco Security Cloud Sign On is not a visibility and remediation mode for Cisco Secure Email Threat Defense. It is a service that manages user authentication for Cisco security products, including Cisco Secure Email Threat Defense3.

To allow phishing simul-ations to bypass antispam scanning, the administrator must add two components to the allow list: domains and senders. Domains are the email domains that are used in the phishing simulations, such as example.com or test.com. Senders are the email addresses that are used to send the phishing simulations, such as [email protected] or [email protected]. By adding these components to the allow list, the administrator can prevent them from being blocked by antispam scanning and allow them to reach the end users for testing purposes. Reference: [Cisco Secure Email Gateway Administrator Guide - Creating Allow Lists]

According to the [Cisco Secure Email User Guide], you can create a text resource of type Disclaimer

Template and use the code view option to insert HTML code into the text box. Then, you can use this text resource in a content filter to prepend or append the HTML message to the email body[1, p. 15-16].

The other options are not valid because:

A. Creating a text resource type of Disclaimer Template and pasting the HTML code into the text box without changing to code view will not work, as the HTML code will be treated as plain text and not rendered properly[1, p. 15].

C. Creating a text resource type of Notification Template and pasting the HTML code into the text box will not work, as Notification Templates are used for sending notifications to senders or recipients, not for modifying the email body[1, p. 17].

D. Creating a text resource type of Notification Template and changing to code view to paste the HTML code into the text box will not work, as Notification Templates are used for sending notifications to senders or recipients, not for modifying the email body[1, p. 17].

Large file attachments will be sent as a securedoc attachment. This means that the recipient will receive an encrypted message with a securedoc.html attachment that contains a link to download the large file from the Cisco Secure Email Encryption Service portal[2, p. 9].

This feature can only be enabled if the Read from Message feature is enabled. The Read from Message feature allows you to encrypt messages based on keywords or phrases in the subject or body of the message. You need to enable this feature before you can enable the large file attachments feature[2, p. 8].

The other options are not valid because:

A. Large file attachments can be sent using both the websafe portal and the Cisco Secure Email Add-In. The websafe portal allows you to compose and send encrypted messages from any web browser, while the Cisco Secure Email Add-In allows you to encrypt messages from your email client such as Outlook[2, p. 6-7].

B. This feature allows users to send up to 100MB of attachments in a secure email, not 50MB[2, p. 9].

D. Large file attachments can be sent using both the websafe portal and the Cisco Secure Email Add-In. The websafe portal allows you to compose and send encrypted messages from any web browser, while the Cisco Secure Email Add-In allows you to encrypt messages from your email client such as Outlook[2, p. 6-7].

Cisco Talos is a cloud service that provides a reputation verdict for email messages based on the sender domain and other attributes such as IP address, sender behavior, message content, and attachment analysis. Cisco Talos is integrated with Cisco Secure Email Gateway and provides realtime threat intelligence and protection against spam, phishing, malware, and other email-borne threats.

The other options are not valid because:

A. Cisco AppDynamics is a cloud service that provides application performance monitoring and optimization for enterprise applications. It does not provide reputation verdicts for email messages.

B. Cisco Secure Email Threat Defense is a cloud service that provides visibility and remediation capabilities for email threats detected by Cisco Secure Email Gateway. It does not provide reputation verdicts for email messages.

C. Cisco Secure Cloud Analytics is a cloud service that provides network visibility and threat detection for cloud environments. It does not provide reputation verdicts for email messages.

A TXT record is a type of DNS record that contains arbitrary text data that can be used for various purposes such as verification, configuration, or authentication. A TXT record can contain the DKIM public key per RFC 6376, which is used to verify the digital signature of an email message generated by the DKIM private key of the sender domain.

The other options are not valid because:

A. A CNAME record is a type of DNS record that maps an alias name to a canonical name or another alias name. It does not contain any DKIM public key information.

B. An AAAA record is a type of DNS record that maps a hostname to an IPv6 address. It does not contain any DKIM public key information.

D. A PTR record is a type of DNS record that maps an IP address to a hostname, which is the reverse of an A or AAAA record. It does not contain any DKIM public key information.

According to the [Cisco Secure Email User Guide], Non-Viral threat detection is a feature of Outbreak Filters that detects and blocks email messages that contain non-viral threats such as phishing, fraud, or social engineering[1, p. 25]. To use this feature, you need to enable either AntiSpam or Intelligent Multi-Scan on your Cisco Secure Email Gateway, as these features provide the necessary scanning and filtering capabilities for Non-Viral threat detection[1, p. 26].

The other options are not valid because:

A. Non-Viral threat detection does not require Antivirus or AMP enablement to properly function.

Antivirus and AMP are features that detect and block email messages that contain viral threats such as malware or ransomware[1, p. 27-28].

B. The Outbreak Filters option Graymail Header does not affect Non-Viral threat detection. Graymail Header is an option that allows you to add a header to email messages that are classified as graymail, which are messages that are not spam but may be unwanted by some recipients, such as newsletters or promotions[1, p. 25].

D. The Outbreak Filters option URL Rewriting does not affect Non-Viral threat detection. URL Rewriting is an option that allows you to rewrite the URLs in email messages to point to a Cisco proxy server, which can scan the URLs for malicious content and redirect the users to a warning page if needed[1, p. 25].
