The firmware itself is signed and encrypted. This ensures that only authentic firmware can be
downloaded to the device.
Secure/non-secure protocols
● Check whether it is necessary to use SNMPv1. SNMPv1 is classified as non-secure.
Make use of the possibility to prevent write access. The product offers corresponding
settings for this.
● If SNMP is activated, change the community names. If unrestricted access is not
necessary, limit access via SNMP.
● Use secure protocols if access to the device is not protected by means of physical
safeguards.
The following protocols provide secure alternatives:
HTTP → HTTPS
● To prevent unauthorized access to the device or network, set up appropriate safeguards
against non-secure protocols.
● Enable only the services (protocols) that will actually be used on the device. The same
applies to the installed interfaces/ports. Unused ports could be used to access the
network downstream from the device.
