Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

Your appliance ships with a 30-day evaluation key for virus scanning engines. During this portion of the 

systemsetup

 command, you can choose to accept one or more license agreements and enable anti-virus 

scanning on the appliance. You must accept a license agreement for each anti-virus scanning engine you 
want to enable on your appliance. 

After you accept the agreement, the anti-virus scanning engine you selected is enabled on the incoming 
mail policy. The Email Security appliance scans incoming mail for viruses, but it does not repair infected 
attachments. The appliance drops infected messages.

See 

 for the anti-virus configuration options available on the appliance. 

This next step prompts you to enable both SenderBase participation and Outbreak Filters. Your appliance 
ships with a 30-day evaluation key for Outbreak Filters.

Outbreak Filters provide a “first line of defense” against new virus outbreaks by quarantining suspicious 
messages until traditional Anti-Virus security services can be updated with a new virus signature file. If 
enabled, Outbreak Filters will be enabled on the default Incoming Mail Policy. 

If you choose to enable Outbreak Filters, enter a threshold value and whether you would like to receive 
Outbreak Filters alerts. For more information about Outbreak Filters and threshold values, see 

.

SenderBase is an email reputation service designed to help email administrators research senders, 
identify legitimate sources of email, and block spammers.

If you agree to participate in the SenderBase Email Traffic Monitoring Network, Cisco will collect 
aggregated statistics about email sent to your organization. This includes summary data on message 
attributes and information on how different types of messages were handled by Email Security 
appliances.

See 

 for more information.

Cisco AsyncOS sends alert messages to a user via email if there is a system error that requires the user’s 
intervention. Add at least one email address that receives system alerts. Separate multiple addresses with 
commas. The email addresses that you enter initially receive all types of alerts at all levels, except for 
Directory Harvest Attack Prevention alerts. You can add more granularity to the alert configuration later 
using the 

alertconfig

 command in the CLI or the System Administration > Alerts page in the GUI. For 

more information, see
