Enable only those services that are used on the device, including physical ports. Free physical
ports can potentially be used to gain access to the network behind the device.
Use the authentication and encryption mechanisms of SNMPv3 if possible. Use strong
passwords.
Con󹪝guration 󹪝les can be downloaded from the device. Ensure that con󹪝guration 󹪝les are
adequately protected.
Con󹪝guration 󹪝les can be password protected during download. You enter passwords on the
WBM page "System > Load & Save > Passwords".
When using SNMP (Simple Network Management Protocol):
Con󹪝gure SNMP to generate a noti󹪝cation when authentication errors occur.
For more information, see WBM "System > SNMP > Noti󹪝cations".
Ensure that the default community strings are changed to unique values.
Use SNMPv3 whenever possible. SNMPv1 and SNMPv2c are considered non-secure and
should only be used when absolutely necessary.
If possible, prevent write access.
Interfaces security
Disable unused interfaces.
Use IEEE 802.1X for interface authentication.
Use the function "Locked Ports" to block interfaces for unknown nodes.
Use the con󹪝guration options of the interfaces, e.g. the "Edge Type".
Con󹪝gure the receive ports so that they discard all untagged frames ("Tagged Frames Only").
