2. Encryption and Authentication
TLS (Transport Layer Security)
protects data transferred over the
network by encrypting file names and formats. The System Administrator
can also add IPSec capabilities to secure Internet Protocol (IP)
communications from lower layer protocols, such as TCP (Transmission
Control Protocol) and UDP (User Datagram Protocol) by authenticating
and encrypting each IP packet of a data stream across the Internet.
Additionally, the imageRUNNER ADVANCE DX 4700 Series supports
IEEE 802.1X, which provides port-based authentication. Authentication
involves communications between a supplicant, authenticator, and
authentication server. The supplicant is authentication software on a
client device. The client device (the imageRUNNER ADVANCE DX 4700
Series) needs the supplicant to provide credentials, such as user
names/passwords or digital certificates, to the authenticator (a wireless
access point). The authenticator then forwards the credentials to the
authentication server (generally a RADIUS database) for verification. If
the credentials are valid in the authentication server database, the client
device can access resources located on the protected side of the
network.
3. Network Port and Application Access Control
Network Port and Application Access Control enables system
administrators to set up only the necessary protocols, such as IPP, FTP,
SNTP, SNMP, RAW, LPD, and others for transferring data. These
protocols can be switched ON and OFF. The administrator can also
disable unneeded services, protocols, ports, and the potential paths of
attack so that attacks on the machine can be minimized.
44 TLS V1.3 is supported by the imageRUNNER ADVANCE DX 4700 Series; however, MEAP
applications, uniFLOW, imageWARE Remote, and the CDS only support up to TLS V1.2.
