AsyncOS 
Reversion

AsyncOS for Web 7.5 supports the ability to revert the AsyncOS for Web operating 
system to a previous qualified build for emergency uses. However, you cannot 
revert to a version of AsyncOS for Web earlier than version 7.5.

Also, effective in version 7.5, when you upgrade to a later version, the upgrade 
process automatically saves the current system configuration to a file on the Web 
Security appliance. (However, Cisco recommends manually saving the 
configuration file to a local machine as a backup.) This allows AsyncOS for Web 
to load the configuration file associated with the earlier release after reverting to 
the earlier version. However, when it performs a reversion, it uses the current 
network settings with the earlier configuration file. 

To revert AsyncOS for Web to a previous version, use the 

revert

 CLI command.

For more information, see the “Reverting to a Previous Version of AsyncOS for 
Web” section in the “System Administration” chapter of the Cisco IronPort 
AsyncOS for Web User Guide.

URL Category 
Updates for URL 
Filtering 

The predefined set of URL categories for Cisco IronPort Web Usage Controls has 
been updated to accommodate new web trends and evolving usage patterns, and the 
system now allows Web Security appliances to automatically download additional 
changes. Category set changes in this release are designed to provide an optimal 
balance between simplicity and flexibility when configuring usage policies.

Additionally, the new set of URL categories associated with this release matches 
the Cisco ScanSafe URL category list, simplifying management for Cisco ScanSafe 
customers.

For more information, see 

 and the “Managing 

Updates to the Set of URL Categories” section in the “URL Filters” chapter of the 
Cisco IronPort AsyncOS for Web User Guide.

User System 
Preferences

In AsyncOS for Web 7.5, local users can define preference settings, such as 
language, specific to each account. These settings apply by default when the user 
first logs into the appliance. Users can change these settings during the appliance 
management session, but the settings revert to the default values when they log in 
again. 

The preference settings are stored for each user and are the same regardless from 
which client machine the user logs into the appliance. 

For more information, see the “Defining User Preferences” section in the “System 
Administration” chapter of the Cisco IronPort AsyncOS for Web User Guide.
