SecureLinx SLC User Guide
A network naming and administration system developed by
Sun Microsystems for smaller networks. Each host client or
server computer in the system has knowledge about the
entire system. A user at any host can access files or
applications on any host in the network with a single user
identification and password.
NIS uses the client/server model and the Remote Procedure
Call (RPC) interface for communication between hosts. NIS
consists of a server, a library of client programs, and some
administrative tools. NIS is often used with the Network File
System (NFS).
A set of protocols for accessing information directories,
specifically X.500-based directory services. LDAP runs over
TCP/IP or other connection-oriented transfer services.
An authentication and accounting system used by many
Internet Service Providers (ISPs). A client/server protocol, it
enables remote access servers to authenticate dial-in users
and authorize their access to the requested system or
service.
RADIUS allows a company to maintain user profiles in a
central database that all remote servers can share. It
increases security, allowing a company to set up a policy
that can be applied at a single administered network point.
Kerberos is a network authentication protocol that enables
two parties to exchange private information across an
unprotected network.
It works by assigning a unique electronic credential, called a
ticket, to each user who logs on to the network. The ticket is
embedded in messages to identify the sender.
