Cisco Cisco Email Security Appliance C680 User Guide

Starting in AsyncOS 7.5, RSA Email DLP scans the From, To, CC:, and Subject 
header of outgoing messages for DLP policy violations. If a DLP policy encrypts 
outgoing messages with DLP violations, it will not encrypt these headings. The 
Email Security appliance only encrypts the message body.

AsyncOS 7.5 includes a configuration history log that consists of a configuration 
file with an additional section listing the name of the user, a description of where 
in the configuration the user made changes, and the comment the user entered 
when committing the change. Each time a user commits a change, a new log is 
created containing the configuration file after the change.

For more information, see the “Logging” chapter in the Cisco IronPort AsyncOS 
for Email Daily Management Guide.

To prevent log files on the appliance from becoming too large, AsyncOS 7.5 
performs a “rollover” and archives a log file when it reaches a user-specified 
maximum file size or time interval and creates a new file for incoming log data. 
Based on the retrieval method defined for the log subscription, the older log file 
is stored on the appliance for retrieval or delivered to an external computer.

For more information, see the “Logging” chapter in the Cisco IronPort AsyncOS 
for Email Daily Management Guide.

With AsyncOS 7.5, you can now access log files at any time by clicking a link to 
the log directory on the Log Subscriptions page, then clicking the log file to 
access. Depending on your browser, you can view the file in a browser window 
or open or save it as a text file. This method uses the HTTP(S) protocol and is the 
default retrieval method.
