3.2 Network Security
Normally the electric meter forms a physical barrier, i.e. only devices connected to this meter can
be part of the network and benefit from the phase coupling. We strongly recommend that you use
the HNP6L-ET and HNX-ET
internal device encryption. It is configured with the Homeplug
PowerPacket Configuration Utility software.
How to Use Passwords Correctly
• You can improve your security substantially by following some important rules regarding
the use of passwords.
• Keep your passwords as secret as possible.
• Never write a password down nor store them in notebooks, wallets and text files in
computers.
• Do not pass on your password unnecessarily.
• Select a random password. Use random strings of letters and numbers. Passwords from
common language usage are not secure.
• Change the password regularly or immediately if you feel it has been compromised.
• Passwords should be changed as frequently as possible. This requires a little effort, but
increases your security considerably. Even if only the slightest indication of a leak exists,
the password should be changed.
To set the Password of the device, first select the device by clicking on its name in the lower
panel and then click on the EnterPassword button.
