Chapter 1 Getting to know your Business Secure Router 37
Nortel Business Secure Router 252 Configuration — Basics
Nortel Contivity Client Termination
The Business Secure Router supports VPN connections from computers using
Nortel Contivity VPN Client 3.0, 5.01, 5.11, 6.01, 6.02, or 7.01 software.
Certificates
The Business Secure Router can use certificates (also called digital IDs) to
authenticate users. Certificates are based on public-private key pairs. Certificates
provide a way to exchange public keys for use in authentication.
SSH
The Business Secure Router uses the SSH (Secure Shell) secure communication
protocol to provide secure encrypted communication between two hosts over an
unsecured network.
HTTPS
HyperText Transfer Protocol over Secure Socket Layer, or HTTP over SSL is a
web protocol that encrypts and decrypts web sessions. Use HTTPS for secure
WebGUI access to the Business Secure Router.
IEEE 802.1x for network security
The Business Secure Router supports the IEEE 802.1x standard for user
authentication. With the local user profile in the Business Secure Router, you can
configure up to 32 user profiles without a network authentication server. In
addition, centralized user and accounting management is possible on an optional
network authentication server.
Firewall
The Business Secure Router has a stateful inspection firewall with DoS (Denial of
Service) protection. By default, when the firewall is activated, all incoming traffic
from the WAN (Wide Area Network) to the LAN is blocked unless it is initiated
from the LAN. The Business Secure Router firewall supports TCP/UDP
inspection, DoS detection and protection, real time alerts, reports and logs.
