Placing iPEPS alongside the firewall
iPEPS 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 iPEPS alongside the firewall and
control a computer that is also IP connected within the local network.
IMPORTANT: If you make the iPEPS accessible from the public Internet, 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.
Ensuring sufficient security
The security capabilities offered by the iPEPS 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 configuration.
• 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 download the viewer.
• Use non-standard port numbers.
• Restrict the range of IP addresses that are allowed to access the iPEPS to only
those that you will need to use. To restrict IP access.
• Do NOT Force VNC protocol 3.3. Remote configuration.
• Ensure that the computer accessing the iPEPS is clean of viruses and
spyware and has up-to-date firewall and anti-virus software loaded that is
appropriately configured.
• Avoid accessing the iPEPS from public computers.
Security can be further improved by using the following suggestions:
• Place the iPEPS 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 iPEPS 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 iPEPS is situated alongside the firewall, it will require a public static IP
address (i.e. one provided by your Internet service provider).
