Security type
Security is used to validate the identification of each device or computer that is attempting to access a
network. The security type used on a network is determined during network design and depends on the
network security requirements. Consequently, security methods are closely associated with encryption
options that are also used on the network.
HP Jetdirect wireless print servers support the following security types:
●
No security . No encryption or authentication is used. Open system. Your wireless network does
not require device authentication or security to access the network. However, your network might
use WEP encryption keys for data privacy.
● WEP-Personal . Each device on your wireless network uses a shared encryption key (a shared
password value) for network access and communication. Each device on the network must use
the same key. The HP Jetdirect print server supports IEEE 802.11 WEP keys for encrypted network
communications.
●
WEP-Enterprise . The network uses WEP with EAP/802.1x authentication. This type of security
utilizes a central authentication server, such as RADIUS, to authenticate users on the network. The
HP Jetdirect print server supports these server-based authentication protocols: LEAP, PEAP, and
EAP-TLS.
● WPA/WPA2–Personal . Your network uses wi-fi protected access (WPA) with a pre-shared key
that is typically generated by a pass-phrase. WPA encryption is normally used for wireless
communication and offers improved security.
●
WPA/WPA2–Enterprise . Your network uses WPA with EAP/802.1x authentication. This type of
security utilizes a central authentication server, such as RADIUS, to authenticate users on the
network. The HP Jetdirect print server supports these server-based authentication protocols:
LEAP, PEAP, and EAP-TLS.
For more information about authentication, see the HP Jetdirect Print Servers Administrator’s Guide
supplied on the HP Jetdirect CD-ROM.
