Placing Adderlink Ip Gold Alongside The Firewall - ADDER AdderLink IP Gold User Manual

Placing AdderLink IP Gold alongside the firewall

AdderLink IP Gold is built from the ground-up to be secure. It employs a
sophisticated 128bit public/private key system that has been rigorously analysed
and found to be highly secure (a security white paper is available upon request
from Adder Technology Ltd). Therefore, you can position the AdderLink IP Gold
alongside the firewall and control hosts that are also IP connected within the
local network.
IMPORTANT: If you make the AdderLink IP Gold accessible from the public
Internet or from a modem, care should be taken to ensure that the maximum
security available is activated. You are strongly advised to enable encryption and
use a strong password. Security may be further improved by restricting client
IP addresses, using a non-standard port number for access or limiting remote
access to dial up connections only.
Ensuring sufficient security
The security capabilities offered by the AdderLink IP Gold are only truly effective
when they are correctly used. An open or weak password or unencrypted link
can cause security loopholes and opportunities for potential intruders. For
network links in general and direct Internet connections in particular, you should
carefully consider and implement the following:
• Ensure that encryption is enabled.
By local configuration or by remote
• Ensure that you have selected secure passwords with at least 8 characters
and a mixture of upper and lower case and numeric characters.
By remote configuration.
• Reserve the admin password for administration use only and use a non-
admin user profile for day-to-day access.
• Use the latest Secure VNC viewer (this has more in-built security than is
available with the Java viewer). To

Gold to only those that you will need to use. To

• Add a further level of inherent security by restricting access only via modem

Security can be further improved by using the following suggestions:
• Use a KVM switch with On-Screen-Display driven security access and an
auto-logout (after inactivity) feature to provide a second level of security. KVM
switches such as the AdderView Matrix or SmartView XPro are recommended.
• Place the AdderLink IP Gold behind a firewall and use port the numbers to
route the VNC network traffic to an internal IP address.
• Review the activity log from time to time to check for unauthorized use.
• Lock your server consoles after they have been used.

Ports
In this configuration there should be no constraints on the port numbers
because the AdderLink IP Gold will probably be the only device at that IP
address. Therefore, maintain the HTTP port as 80 and the VNC port as 5900.
Addressing
When the AdderLink IP Gold is situated alongside the firewall, it will require a
public static IP address (i.e. one provided by your Internet service provider).
