TACACS
Terminal Access Controller Access-Control System (TACACS, ) refers to a family of related protocols handling remote authentication and related services for network access control through a centralized server. The original TACACS protocol, which dates back to 1984, was used for communicating with an authentication server, common in older UNIX networks including but not limited to the ARPANET, MILNET and BBNNET. It spawned related protocols: * Extended TACACS (XTACACS) is a proprietary extension to TACACS introduced by Cisco Systems in 1990 without backwards compatibility to the original protocol. TACACS and XTACACS both allow a remote access server to communicate with an authentication server in order to determine if the user has access to the network. * TACACS Plus (TACACS+) is a protocol developed by Cisco and released as an open standard beginning in 1993. Although derived from TACACS, TACACS+ is a separate protocol that handles authentication, authorization, and accounting (AA ...

Authentication Protocol
An authentication protocol is a type of computer communications protocol or cryptographic protocol specifically designed for transfer of authentication data between two entities. It allows the receiving entity to authenticate the connecting entity (e.g. Client connecting to a Server) as well as authenticate itself to the connecting entity (Server to a client) by declaring the type of information needed for authentication as well as syntax. It is the most important layer of protection needed for secure communication within computer networks. Purpose With the increasing amount of trustworthy information being accessible over the network, the need for keeping unauthorized persons from access to this data emerged. Stealing someone's identity is easy in the computing world - special verification methods had to be invented to find out whether the person/computer requesting data is really who he says he is. The task of the authentication protocol is to specify the exact series of steps n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AAA Protocol
Authentication, authorization, and accounting (AAA) is a framework used to control and track access within a computer network. Authentication is concerned with proving identity, authorization with granting permissions, accounting with maintaining a continuous and robust audit trail via logging. Common network protocols providing this functionality include TACACS+, RADIUS,C. Rigney, S. Willens, A. Rubens, W. Simpson, "Remote Authentication Dial In User Service (RADIUS)", IETF RFC 2865, June 2000. and Diameter.P. Calhoun, J. Loughney, E. Guttman, G. Zorn, J. Arkko, "Diameter Base Protocol", IETF RFC 3588, September 2003.Sasu Tarkoma, "Mobile Middleware: Architecture, Patterns and Practice", John Wiley and Sons, 2009, pp. 248–251. . Disambiguation In some related but distinct contexts, the term AAA has been used to refer to protocol-specific information. For example, Diameter uses the URI scheme AAA, which also stands for "Authentication, Authorization and Accounting", as well ...

Cisco IOS
The Internetworking Operating System (IOS) is a family of proprietary network operating systems used on several router and network switch models manufactured by Cisco Systems Cisco Systems, Inc. (using the trademark Cisco) is an American multinational corporation, multinational digital communications technology conglomerate (company), conglomerate corporation headquartered in San Jose, California. Cisco develops, m .... The system is a package of routing, switching, internetworking, and telecommunications functions integrated into a computer multitasking, multitasking operating system. Although the IOS code base includes a cooperative multitasking kernel, most IOS features have been ported to other kernels, such as Linux and QNX, for use in Cisco products. Not all Cisco networking products run IOS. Exceptions include some Cisco Catalyst switches, which run Cisco IOS XE, IOS XE, and Cisco ASR routers, which run either IOS XE or Cisco IOS XR, IOS XR; both are Linux-based op ...

Computer Access Control Protocols
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as ''programs'', which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots. Computers are at the core of general-purpose devices such as personal computers and mobile devices such as smartphones. Computers power the Internet, which links billions of computer ...

Openwall
The Openwall Project is a source for various software, including Openwall GNU/*/Linux (Owl), a security-enhanced Linux distribution designed for servers. Openwall patches and security extensions have been included into many major Linux distributions. As the name implies, Openwall GNU/*/Linux draws source code and design concepts from numerous sources; most importantly to the project is its usage of the Linux kernel and parts of the GNU userland, and others include the BSDs, such as OpenBSD for its OpenSSH suite and the inspiration behind its own Blowfish-based crypt for password hashing, compatible with the OpenBSD implementation. Public domain software The Openwall project maintains also a list of algorithms and source code which is public domain software. Openwall GNU/*/Linux releases LWN.net reviewed Openwall Linux 3.0. They wrote: ''PoC, , GTFO'' Issues of the ''International Journal of Proof-of-Concept or Get The Fuck Out'' (''PoC, , GTFO'') are mirrored ...

RADIUS
In classical geometry, a radius (: radii or radiuses) of a circle or sphere is any of the line segments from its Centre (geometry), center to its perimeter, and in more modern usage, it is also their length. The radius of a regular polygon is the line segment or distance from its center to any of its Vertex (geometry), vertices. The name comes from the Latin ''radius'', meaning ray but also the spoke of a chariot wheel.Definition of Radius at dictionary.reference.com. Accessed on 2009-08-08. The typical abbreviation and mathematical symbol for radius is ''R'' or ''r''. By extension, the diameter ''D'' is defined as twice the radius:Definition of radius at mathwords.com. ...

Diameter (protocol)
Diameter is an authentication, authorization, and accounting (AAA) protocol for computer networks. It evolved from the earlier RADIUS protocol. It belongs to the application layer protocols in the Internet protocol suite. ''Diameter Applications'' extend the base protocol by adding new commands and/or attributes, such as those for use with the Extensible Authentication Protocol (EAP). Comparison with RADIUS The name is a play on words, derived from the RADIUS protocol, which is the predecessor (a diameter is twice the radius). Diameter is not directly backward compatible but provides an upgrade path for RADIUS. The main features provided by Diameter but lacking in RADIUS are: * Support for SCTP * Capability negotiation * Application layer acknowledgements; Diameter defines failover methods and state machines (RFC 3539) * Extensibility; new commands can be defined * Aligned on 32 bit boundaries Also: Like RADIUS, it is intended to work in both local and roaming AAA si ...
