•Security
The CheetahAccess Wireless Gateway supports security features that can deny
Internet access to specified users, or filter all requests for specific services the
administrator does not want to serve. The CheetahAccess Wireless Gateway’s
firewall can also block common hacker attacks, including IP Spoofing, Land Attack,
Ping of Death, IP with zero length, Smurf Attack, UDP port loopback, Snork Attack,
TCP null scan, and TCP SYN flooding.
• Virtual Private Network
The CheetahAccess Wireless Gateway supports three of the most commonly used
VPN protocols – PPTP, L2TP and IPSec. These protocols allow remote users to
establish a secure connection to their corporate network. If your service provider
supports VPNs, then any of these protocols can be used to create an authenticated
and encrypted tunnel for passing secure data over the Internet (i.e., a traditionally
shared data network). The VPN protocols supported by the CheetahAccess
Wireless Gateway are briefly described below.
- Point-to-Point Tunneling Protocol – Provides a secure tunnel for
remote client access to a PPTP security gateway. PPTP includes
provisions for call origination and flow control required by ISPs.
- Layer Two Tunneling Protocol – Includes most of the features
provided by PPTP, but has less overhead and is more suited for
managed networks.
- IP Security – Provides IP network-layer encryption. IPSec can
support large encryption networks (such as the Internet) by using
digital certificates for device authentication.
