Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

Who is triggering which content filters?

Whose email is getting caught by content filters?

Inbound Internal Users are the users for which you received email, based on the Rcpt To: address. 
Outbound Internal Users are based on the Mail From: address and are useful when tracking the types of 
email that senders on your internal network are sending.

Note that some outbound mail (like bounces) have a null sender. They are counted under outbound and 
“unknown.”

Click on an internal user to view the Internal User detail page for that user. 

Click the Columns link below the table to show columns that are hidden by default, such as the Incoming 
Detected by Advanced Malware Protection column. 

The Internal User detail page shows detailed information about the specified user, including a breakdown 
of incoming and outgoing messages showing the number of messages in each category (spam detected, 
virus detected, stopped by content filter, and clean). Optionally, for incoming messages, you can click 
the Columns link below the table to show the Incoming Detected by Advanced Malware Protection 
column. This value reflects the number messages that contained attachments that were determined by 
file reputation filtering to be malicious. It does not include verdict updates or files found to be malicious 
by file analysis. Incoming and outgoing content filter and DLP policy matches are also shown.

Click on a content filter name to view detailed information for that filter in the corresponding content 
filter information page (see 

). You can use this method to get a list of 

users who also sent or received mail that matched that particular content filter.

You can search for a specific internal user (email address) via the search form at the bottom of the 
Internal Users page and the Internal User detail page. Choose whether to exactly match the search text 
or look for items starting with the entered text (for instance, starts with “ex” will match “example.com”).

The DLP Incidents page shows information on the incidents of data loss prevention (DLP) policy 
violations occurring in outgoing mail. The appliance uses the DLP email policies enabled in the 
Outgoing Mail Policies table to detect sensitive data sent by your users. Every occurrence of an outgoing 
message violating a DLP policy is reported as an incident. 

Using the DLP Incidents report, you can answer these kinds of questions:

What type of sensitive data is being sent by your users?

How severe are these DLP incidents?

How many of these messages are being delivered?

How many of these messages are being dropped?
