1.2.2 Security
Connecting your computer to the Internet exposes it to a wide range of risks. The Si wireless
home gateway comes with security functions to safeguard your system and data. Three types of interfaces
can be controlled by the Firewall: Internal (LAN), external (WAN) and DMZ (DeMilitarized Zone). A DMZ is
usually used by a company that wants to host its own Internet services without sacrificing unauthorized
access to its private network. Typically, the DMZ contains devices accessible to Internet traffic such as
HTTP, FTP, DNS and SMTP servers. You can configure the Firewall to allow or block access from one
interface type to another interface type.
You can configure the Firewall by using a default Security level, by Firewall port filters, by Firewall
validators and by Security triggers.
