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.
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 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.
Brute force password guessing protection
The Business Secure Router has a special protection mechanism to discourage
brute force password guessing attacks on the Business Secure Router’s
management interfaces. You can specify a wait time that must expire before you
can enter a fourth password after entering three incorrect passwords.
Content filtering
The Business Secure Router can block web features such as ActiveX controls,
Java applets, and cookies, as well as disable web proxies. The Business Secure
Router can block specific URLs by using the keyword feature. The administrator
can also define time periods and days during which content filtering
is enabled.
Packet filtering
The packet filtering mechanism blocks unwanted traffic from entering or leaving
your network.
