Security 
The SVG2500 provides the following: 
•  A 
firewall 
to protect the SVG2500 LAN from undesired attacks over the Internet 
•  For wireless transmissions, data encryption and network access control 
Network Address Translation 
(NAT) 
provides some security because the IP 
addresses of SVG2500 LAN computers are not visible on the Internet. 
This diagram does not necessarily correspond to the network cabling. A full 
discussion of network security is beyond the scope of this document.
