A method of proving a person’s identity based on a user name and password.


A method of data encryption and decryption.

HyperText Transfer Protocol (HTTP)

A standard Internet transport protocol used by Web sites and Web browsers. NetIQ Operations Center is fully Web-enabled; therefore, users can connect to Operations Center via a standard Web browser that uses HTTP.

HyperText Transfer Protocol, Secure (HTTPS)

A secure Internet transport protocol used by Web sites and Web browsers. Commonly identified by the padlock icon displayed in a browser when a secured, authenticated session is established with a Web server. Operations Center supports the use of HTTPS to provide secure connections between a client and server.

Internet Inter-Orb Protocol (IIOP)

A standard protocol that eases legacy application and platform integration by allowing application components written in C++, Smalltalk, and other CORBA supported languages to communicate with components running on the Java platform. Operations Center uses unidirectional IIOP for its communications between ORBs and Operations Center servers.

Bidirectional Internet Inter-Orb Protocol (IIOP)

A dialect or modification of standard IIOP that permits better navigation through corporate firewalls and network address translation (NAT) devices. This protocol does not establish two socket channels to communicate bidirectionally; it reuses the socket established by the first connecting side of a two-way channel. Operations Center uses bidirectional IIOP for its base communications between Operations Center clients and servers and between Operations Center servers.

Lightweight Directory Access Protocol (LDAP)

An open, platform-independent, and vendor-independent information model and network protocol for querying and manipulating information in a directory. LDAP is essentially X.500 designed specifically to run on TCP/IP. It has become the standard used throughout large companies to access directory information about users and resources. With its External I&A Option, Operations Center supports integration with LDAP for external identification and authorization.

Secure Sockets Layer (SSL) Protocol

A standard protocol for secure communication over a network. SSL uses a combination of cryptographic protocols for authentication, privacy, and data protection of Internet communications. The application most commonly used with SSL is Hypertext Transfer Protocol (HTTP), which is the protocol for Internet Web pages. Lightweight Directory Access Protocol (LDAP) and other protocols, such as File Transfer Protocol (FTP), can also be used with SSL. Operations Center provides configurable options for using SSL to secure communications between Operations Center clients and servers, as well as between Operations Center servers and Operations Center ORBs and LDAP.

Tiny Encryption Algorithm (TEA) Cipher

One of the fastest and most efficient cryptographic algorithms. Operations Center uses the TEA Cipher to encrypt passwords.


A standard that describes an overall model for directory services, providing an information model and a network protocol for querying and manipulating information in a directory. Operations Center implements an X.500 directory structure for managing its internal data.
