Option
Description
Default System 
Hostname
The fully-qualified hostname for the Web Security appliance. This name 
should be assigned by your network administrator. This hostname is used to 
identify the appliance in system alerts.
DNS Server(s): 
 
Use the Internet’s Root 
DNS Servers
Configures the appliance to use the Internet root DNS servers for domain 
name service lookups.
You might choose this option when the appliance does not have access to 
DNS servers on your network.
The appliance requires access to a working DNS server in order to perform 
DNS lookups for incoming connections. If you cannot specify a working 
DNS server that the appliance can reach while you set up the appliance, you 
can configure it to use the Internet root DNS servers or temporarily assign the 
IP address of the Management interface so that you can complete the System 
Setup Wizard.
For more information about configuring DNS settings, see 
DNS Server(s): 
 
Use these DNS Servers
Specifies local DNS servers for domain name service lookups. You must 
enter at least one DNS server, and up to three total.
You can choose to use the Internet root DNS servers or specify your own 
DNS servers.
For more information about configuring DNS settings, see 
NTP Server
Uses a Network Time Protocol (NTP) server to synchronize the system clock 
with other servers on the network or the Internet.
By default, the Cisco IronPort time server (time.ironport.com) is entered.
Time Zone
Sets the time zone on the appliance so that timestamps in message headers 
and log files are correct. Use the drop-down menus to locate your time zone 
or to define the time zone using the GMT offset.
For more information about the GMT offset, see
