Руководство Пользователя для Cisco Cisco Email Security Appliance C170

In AsyncOS 7.1, you can control from which IP addresses users access the Email 
Security appliance. Users can access the appliance from any machine with an IP 
address from an access list you define. You can create the list using the GUI or the 

adminaccessconfig > ipaccess 

command in the CLI. See 

 for more information.

AsyncOS 7.1 allows you to display a customizable message called a “login 
banner” when a user attempts to log into the Email Security appliance through 
SSH, Telnet, FTP, or Web UI. The login banner appears above the login prompt in 
the CLI and to the right of the login prompt in the GUI. The login banner can only 
be created using the 

adminaccessconfig > banner

 command. See 

 for more information.

In AsyncOS 7.1 adds the option of a No Password Required security level to 
encryption profiles. This is the lowest level of encrypted message security. The 
recipient does not need to enter a password to open the encrypted message, but the 
read receipts, Secure Reply, Secure Reply All, and Secure Message Forwarding 
features will be unavailable to prevent another email user from sending a message 
on behalf of the original recipient. See 

 for more information.

transmitted or received over the network to which the appliance is attached. This 
feature can help you debug the network setup and to discover what network traffic 
is reaching the appliance or leaving the appliance. A
