Cisco Cisco Email Security Appliance C160 Mode D'Emploi

You specify primary and secondary actions that the Email Security appliance will take when it detects a 
possible DLP violation in an outgoing message. Different actions can be assigned for different violation 
types and severities. 

Primary actions include: 

Deliver 

Drop

Quarantine 

Secondary actions include: 

Sending a copy to a policy quarantine if you choose to deliver the message. The copy is a perfect 
clone of the original, including the Message ID. Quarantining a copy allows you to test the RSA 
Email DLP system before deployment in addition to providing another way to monitor DLP 
violations. When you release the copy from the quarantine, the appliance delivers the copy to the 
recipient, who will have already received the original message.

Encrypting messages. The appliance only encrypts the message body. It does not encrypt the 
message headers.

Altering the subject header of messages containing a DLP violation.

Adding disclaimer text to messages.

Sending messages to an alternate destination mailhost.

Sending copies (bcc) of messages to other recipients. (For example, you could copy messages with 
critical DLP violations to a compliance officer’s mailbox for examination.)

Sending a DLP violation notification message to the sender or other contacts, such as a manager or 
DLP compliance officer. See 

. 

These actions are not mutually exclusive: you can combine some of them within different DLP policies 
for various processing needs for different user groups. You can also configure different treatments based 
on the different severity levels in the same policy. For example, you may want to quarantine messages 
with critical DLP violations and send a notification to a compliance officer, but you may want to deliver 
messages with low severity levels.

Create at least one dedicated quarantine to hold messages (or copies of messages) that violate DLP 
policies. 

This can be a local quarantine on an Email Security appliance or a centralized quarantine on a 
Security Management appliance.
