E. Network Security
The imageRUNNER ADVANCE DX 4700 Series machines secure network
communications by using IP Address and MAC (Media Access Control)
Address filters, encryption and authentication, and network port and
application access control.
1. IP Address and MAC Address Filters
IP Address Filter performs a function similar to many firewalls. It permits
or rejects incoming packets from up to 16 IP addresses or ranges of IP
addresses. Also, IP address filters to outbound connections can be
applied. For example, if such functions as Remote Copy and Universal
Send are used, system administrators can block or restrict users from
sending files to specific IP addresses. This helps to minimize the risk of
data being sent out of the company to systems that are not trusted.
MAC Address Filter permits or rejects access for up to 100
MAC
addresses. It is useful for environments that use DHCP (Dynamic Host
Configuration Protocol) for IP address assignments. If DHCP leases
expire and a new IP address is issued to a certain system, the filter can
still identify the system’s MAC address, and permit or reject access to the
machine. MAC addresses can be easily added, edited, or deleted through
the Remote UI. MAC Address Filter takes a higher priority than IP
Address Filter, which prevents unknown systems from attacking the
machine.
