Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

When the Email Security appliance sends DLP incident data to Enterprise Manager, the appliance must 
include the complete LDAP distinguished names in order to identify message senders. The appliance 
retrieves this information from an LDAP server. 

Complete all steps to this point in the table in 

. The User Distinguished Name Query option is not 

available unless you follow these instructions. 

Create an LDAP server profile on your Email Security appliance. See 

 

for more information.

Create a query string that the appliance will use to retrieve the complete distinguished name unless 
you want to use the default query. For Active Directory servers, the default query string is 

(proxyAddresses=smtp:{a})

. For OpenLDAP servers, the default query string is 

(mail={a})

. You 

can define your own query and email attributes, including multiple attributes separated by commas.

Select System Administration > LDAP on the Email Security appliance.

Edit the profile for the LDAP server you want to use.

Select the check box for User Distinguished Name Query. 

This option is available only if you have selected RSA Enterprise Manager as the DLP deployment 
option. 

Enter a name for the query.

Enter the query string for retrieving the user distinguished name.

Click the button to test your query. 

Submit and commit your changes.

You will use Enterprise Manager to associate Outgoing Mail Policies with DLP policies, in order to 
specify which DLP policies apply to which senders and recipients. For information, see the RSA 
Enterprise Manager documentation. Enterprise Manager sends this information to the Email Security 
appliances for use when scanning messages. 

Unlike with RSA Email DLP, outgoing mail policies cannot use the default mail policy’s DLP settings 
when Enterprise Manager is enabled. If a mail policy is not specified for a DLP policy in Enterprise 
Manager, DLP scanning is not enabled on the mail policy. 

If you want to migrate your existing RSA Email DLP configuration to RSA Enterprise Manager, you can 
export your DLP configuration to a .zip file that you can upload to Enterprise Manager before switching 
the appliance from RSA Email DLP mode to RSA Enterprise Manager mode.
