The name format and target location of the CSD image is disk0:/csd_<n>.<n>.*.pkg. The image name format of versions earlier than Cisco Secure Desktop 3.4 is securedesktop_asa_<n>_<n>*.pkg. The latest CSD image includes the Host Scan updates and Advanced Endpoint Assessment (AEA) remediation software. You must install and retain this image on the flash device of the ASA to enable CSD. To use the AEA, you must have an AEA license.
The adaptive security appliance configuration file retains the configuration settings in the Secure Desktop Manager > Setup panel when you click Apply All in that window. When you enable Secure Desktop Manager, it reads all other CSD configuration data from the disk0:/sdesktop/data.xml file on the flash device of the security appliance. Secure Desktop Manager automatically generates this file if it is not present. If you click Apply All in any other Secure Desktop Manager window, Secure Desktop Manager records the changes to the data.xml file. If you click Reset All in any Secure Desktop Manager panel other than Setup, all unapplied changes from your session are removed.
The ASDM Tools > Backup Configurations and Restore Configurations options let you back up and restore both the /sdesktop/data.xml file and CSD image.
You can also transfer a copy of the /sdesktop/data.xml file to the flash device of another ASA before enabling CSD on it, if you want to duplicate the CSD configuration.
