| TERM | DEFINITION | ||
|
|
|
|
|
| A type of firewall that tracks each connection, traversing all firewall | |||
|
| interfaces to ensure validity. In addition to examining the source and | ||
|
| destination in the packet header based on static rules, a stateful | ||
|
| inspection firewall: | ||
|
| • | Examines packet headers via the context established by previous | |
|
|
| packets that traversed the firewall | |
|
| • | Monitors the connection state and saves it in a table | |
|
| • | Closes ports until a connection to a specific port is requested | |
|
| • | May examine the packet contents up through the application layer | |
|
|
| to determine more than just the source and destination | |
|
| A stateful inspection firewall is more advanced than a static filter | ||
|
| firewall. | ||

| subscriber | A home or office user who accesses television, data, or other | ||
|
| services from an Internet Service provider. | ||
|
|
| ||
| synchronous | The SBG901 uses synchronous timing for upstream data | ||
|
| transmissions. The CMTS broadcasts timing messages that | ||
|
| bandwidth is available. The SBG901 reserves data bytes requiring x | ||
|
| number of | ||
|
| specified time (synchronized). At the specified time, the SBG901 | ||
|
| transmits the | ||
|
|
| ||
| upstream | In a cable data network, upstream describes the direction of data | ||
|
| sent from the subscriber’s computer through the cable modem to | ||
|
| the CMTS and the Internet. | ||

| Wireless Cable Modem | The Motorola SURFboard Wireless Cable Modem Gateway is a | ||
| Gateway | single device that combines a cable modem, router, Ethernet switch, | ||
|
| wireless access point, and DHCP server for SOHO or SME use. | ||

| ||
| WPA | |||
|
| Alliance web page: http://www.wifialliance.org. It is a far more robust | ||
|
| form of encryption than WEP. Motorola recommends using WPA if | ||
|
| all of your client hardware supports WPA. | ||
