Security
The Motorola SURFboard Wireless Cable Modem Gateway provides:
•
A firewall to protect the SBG1000 LAN from undesired attacks over the Internet
•
Security measures to prevent eavesdropping of wireless data
Network Address Translation ( NAT ) provides some security because the IP addresses of SBG1000 LAN
computers are not visible on the Internet.
The logical network diagram does not necessarily correspond to the network cabling. A full discussion of network
security is beyond the scope of this document.
