You can configure how the Email Security appliance downloads AsyncOS upgrades and updates. Cisco 
provides two methods (or “sources”) for upgrades and updates: streaming and remote. 

With streaming upgrades and updates, your Cisco appliances download the files directly from the Cisco 
update servers. Each Cisco appliance downloads the files separately. For more information, see 

.

For remote upgrades and updates, your Cisco appliances download the files from a server within your 
network. You only download the files from Cisco one time, and then serve them to your Cisco 
appliances. For more information, see 

.

Use the Security Services > Service Updates page to choose upgrading and updating methods (streaming 
is the default), as well as configure the system for these processes. For more information, see 

. Optionally, use the 

updateconfig

 command in the CLI.
