Cisco Cisco Web Security Appliance S670 Release Notes

When you upgrade AsyncOS for Web from the web interface or Command Line Interface (CLI), the 
configuration is saved to file in the /configuration/upgrade directory. You can access the upgrade 
directory using an FTP client. Each configuration file name is appended with the version number, and 
passwords in the configuration file are masked so they are not human readable.  

Generally, configuration files from earlier AsyncOS releases are incompatible with later AsyncOS 
releases and vice-versa. 

The encryption strength of the demo security certificate is 1024 bits both before and after upgrade to 
AsyncOS 8.5 and later. 

You must reboot the Web Security appliance after you upgrade AsyncOS for Web.

This section describes changes in behavior from previous versions of AsyncOS for Web that may affect 
the appliance configuration after you upgrade to the latest version. 

Beginning in AsyncOS 8.5, all available releases appear in the list of available upgrades, including 
releases that would previously have been provisioned only to a limited number of customers as a limited 
release. 

Each release in the list is identified by the release type (ED - Early Deployment, GD - General 
Deployment, MD - Maintenance Deployment, etc.) For an explanation of these terms, see 

. 

Beginning in AsyncOS 8.5, in order to open a support request from the appliance, you must enter a CCO 
ID and a support contract ID. 

Beginning in AsyncOS 8.5, certificate management functionality has been moved from the Security 
Services > HTTPS Proxy page to a new, stand-alone page: Network > Certificate Management.
