Appendix D: Protocol Glossary
BOOTP (Bootstrap Protocol)
Similar to DHCP, but for smaller networks. Automatically assigns the IP address for a specific
duration of time.
CHAP (Challenge Handshake Authentication Protocol)
A secure protocol for connecting to a system; it is more secure than the PAP.
DHCP (Dynamic Host Configuration Protocol)
Internet protocol for automating the configuration of computers that use TCP/IP.
DNS (Domain Name Servers)
A system that allows a network nameserver to translate text host names into numeric IP
addresses.
EAP (Extensible Authentication Protocol )
An authentication framework used to pass the authentication information between the supplicant
(the console manager) and the authentication server. See also EAP-TLS, EAP-TTLS, FAST,
LEAP, and PEAP.
EAP-TLS (EAP Transport Layer Security)
An authentication protocol that uses TLS and Public key infrastructure (PKI) to set up
authentication with a RADIUS server. This method requires the use of a client-side certificate for
communicating with the server.
EAP-TTLS (EAP Tunneled Transport Layer Security)
An authentication protocol that uses TTLS and server-side certificates to set up authentication
between the console manager and a RADIUS server. The actual authentication is, however,
performed using passwords.
FAST (Flexible Authentication via Secure Tunneling)
An authentication protocol that uses Protected Access Credential (PAC) for verifying clients on the
network. Instead of using a certificate to achieve mutual authentication, FAST authenticates by
means of a PAC stored on the console manager, which can be managed dynamically by the
authentication server.
FTP (File Transfer Protocol)
A protocol for transferring files between computers on a network that is insecure by design and
susceptible to interception. See also SCP, SFTP, and TFTP.
IKEv1 and IKEv2 (Internet Key Exchange)
A protocol used to set up a security association in the IPsec protocol suite that allows two parties
to send data securely.
