300-720 Exam Dumps : Securing Email with Cisco Email Security Appliance (300-720 SESA)

one of the methods to enable Cisco SecureX integration on a Cisco Secure Email Gateway appliance is to use the Threat Response service1. This service allows the appliance to send telemetry data to the SecureX cloud and provide visibility and response capabilities across multiple security products1. To use this service, the administrator needs to perform the following steps1:

• Enable the Threat Response service: The administrator needs to go to Network > Cloud Service Settings and enable the Threat Response service. This will generate a registration token that can be used to register the appliance with SecureX1.
• Select the correct Threat Response Server: The administrator needs to select the appropriate Threat Response server based on the region where the appliance is located. The available regions are North America, Europe, and Asia Pacific1.

To enable File Reputation and File Analysis on the Cisco Secure Email Gateway appliance, the administrator must configure the appliance to use SSL for the connection to the File Reputation server. This will ensure that the communication between the appliance and the cloud service is secure and encrypted. The administrator must also upload a valid certificate from a trusted CA on the appliance for this purpose. The other options are not required or effective for this task. References: [Cisco Secure Email Gateway Administrator Guide - Configuring File Reputation and File Analysis]

Configuring the outbound firewall rule to permit traffic on port 3237 is the additional action that resolves the issue. AMP file reputation is a feature that allows Cisco ESA to check files attached to messages against a cloud-based database of known malicious files and apply appropriate actions, such as block, deliver, or quarantine.

By default, AMP file reputation uses TCP port 3237 to communicate with the cloud-based database. If this port is blocked by a firewall, AMP file reputation will not work properly.

To resolve this issue, the administrator can configure the outbound firewall rule to permit traffic on port 3237 from Cisco ESA.

The other options are not valid actions to resolve the issue, because they do not affect the port used by AMP file reputation.
