!!! Overview
[{$pagename}] is a computing term that refers to an application outside the [operating system] that provides a layer of security to various system artifacts.
The term is typically seen when referring to security products on [IBM] [z/OS|zOS] platforms. An example is the [RACF] security package. [1]
[{$pagename}] is best known on [IBM] [Mainframe]
On [z/OS|zOS] there are three primary External Security Managers (ESM)
* [RACF] - Short for [Resource Access Control Facility], is an [IBM] software product. It is a security system that provides access control and auditing functionality for the z/OS and z/VM operating systems. [RACF] was introduced in [1976|Year 1976]
* [Top Secret] - [Computer Associates]
* [ACF2] ([Access Control Facility])
In 1987, acquisitions made [Computer Associates] the largest independent vendor of mainframe infrastructure software and dominant vendor of OS/MVS security software with CA-Top Secret (#2 market share) and CA-ACF2 (#1 market share). IBM's RACF product held the #3 market share position.
I really have no idea where market share of these products are today.
[{$pagename}] is an [Authentication Agent] for [z/OS|zOS] platforms and can be utilized to provide [Single Sign-On] for applicaitons on the platform.
There is a [DirXML] [ZOS BIDIRECTIONAL DRIVER] that will work with most of the [{$pagename}] on [z/OS|zOS] platforms.
