1.4 Security Notes
The WebRelay is a dedicated device and does not employ a general purpose computer operating
system (i.e. Windows, Linux etc.) It does not have features such as telnet, FTP, SSH, nor uncontrolled
open ports. This means it is extremely difficult if not impossible for someone to ‘break in’ to the
WebRelay and access other devices on your local network. WebRelay does not support remote
firmware updates which means that it is not possible for someone to remotely install malicious software.
The simplicity of the WebRelay makes it an inherently secure device. Nevertheless, as with any device
installed on a network, appropriate security precautions should be observed.
It is recommended that passwords be enabled for the Control Page and Setup Pages. Passwords
should be at least 8 characters in length and use a combination of upper and lower case letters and
numbers. For additional security, a firewall may be used to limit access to selected IP addresses.
Another option may be to set up a Virtual Private Network (VPN) between the network where WebRelay
resides and the client machine (web browser, second WebRelay, etc.).
The firmware in the WebRelay can be upgraded, but not over the internet. By design, a firmware
upgrade requires physical access to a button on the WebRelay enclosure.
