ACF2
ACF2 (Access Control Facility 2) is a commercial, discretionary access control software security system developed for the MVS (z/OS today), VSE (z/VSE today) and VM (z/VM today) IBM mainframe operating systems by SKK, Inc. Barry Schrager, Eberhard Klemens, and Scott Krueger combined to develop ACF2 at London Life Insurance in London, Ontario in 1978. The "2" was added to the ACF2 name by Cambridge Systems (who had the North American marketing rights for the product) to differentiate it from the prototype, which was developed by Schrager and Klemens at the University of Illinois—the prototype name was ACF. The "2" also helped to distinguish the product from IBM International Business Machines Corporation (using the trademark IBM), nicknamed Big Blue, is an American Multinational corporation, multinational technology company headquartered in Armonk, New York, and present in over 175 countries. It is ...'s ACF/VTAM. ACF2 was developed in response to IBM's RACF produc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RACF
Resource Access Control Facility (RACF) is an IBM software security product that provides access control and auditing functions for the z/OS and z/VM operating systems. RACF was introduced in 1976. Originally called RACF it was renamed to z/OS Security Server (RACF), although many mainframe professionals still refer to it as RACF. Its main features are: * Identification and verification of a user via user id and password check (authentication) * Identification, classification and protection of system resources * Maintenance of access rights to the protected resources (access control) * Controlling the means of access to protected resources * Logging of accesses to a protected system and protected resources (auditing) RACF establishes security policies rather than just permission records. It can set permissions for file patterns—that is, set the permissions even for files that do not yet exist. Those permissions are then used for the file (or other object) created at a late ...

Commercial Software
Commercial software, or, seldom, payware, is a computer software that is produced for sale or that serves commercial purposes. Commercial software can be proprietary software or free and open-source software. Background and challenge While software creation by programming is a time and labor-intensive process, comparable to the creation of physical goods, the reproduction, duplication and sharing of software as digital goods is in comparison disproportionately easy. No special machines or expensive additional resources are required, unlike almost all physical goods and products. Once the software is created it can be copied in infinite numbers, for almost zero cost, by anyone. This made commercialization of software for the mass market in the beginning of the computing era impossible. Unlike hardware, it was not seen as trade-able and commercialize-able good. Software was plainly shared for free (hacker culture) or distributed bundled with sold hardware, as part of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CA Technologies
CA Technologies, Inc., formerly Computer Associates International, Inc., and CA, Inc., was an American multinational corporation, multinational enterprise software developer and publisher that existed from 1976 to 2018. CA grew to rank as one of the largest independent software corporations in the world, and at one point was the second largest. The company created systems software (and for a while applications software) that ran in IBM mainframe, distributed computing, virtual machine, and cloud computing environments. The company's primary founder was Charles Wang. The main key to Computer Associates' fast growth was the acquisition of many lesser-sized software companies in the IBM mainframe industry segment. CA was known for large-scale dismissals of employees in the acquired firms, and for sometimes extracting cash flow from acquired products rather than enhancing them. Customers of CA often criticized the company for its poor technical support and hostile attitude. CA und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SHARE (computing)
SHARE Inc. is a volunteer-run user group for IBM mainframe computers that was founded in 1955 by Los Angeles-area users of the IBM 704 computer system. It evolved into a forum for exchanging technical information about programming languages, operating systems, database systems, and user experiences for enterprise users of small, medium, and large-scale IBM computers such as IBM S/360, IBM S/370, zSeries, pSeries, and xSeries. Despite the capitalization of all letters in the name, the official website says "SHARE is not an acronym; it's what we do." Overview A major resource of SHARE from the beginning was the SHARE library. Originally, IBM distributed what software it provided in source form and systems programmers commonly made small local additions or modifications and exchanged them with other users. The SHARE library and the process of distributed development it fostered was one of the major origins of open source software. In 1959 SHARE released the SHARE Operating Sy ...

ACF/VTAM
Virtual Telecommunications Access Method (VTAM) is the IBM subsystem that implements Systems Network Architecture (SNA) for mainframe environments. VTAM provides an application programming interface (API) for communication applications, and controls communication equipment such as adapters and controllers. In modern terminology, VTAM provides a communication stack and device drivers. History VTAM was introduced in 1974 after a series of delays as a major component of SNA along with the 370x Network Control Program (NCP) and Synchronous Data Link Control (SDLC). In IBM terminology, VTAM is an access method software allowing application programs to read and write data to and from external devices. It is called 'virtual' because it was introduced at the time when IBM was introducing virtual storage by upgrading the operating systems of the System/360 series to virtual storage versions. VTAM was supposed to be the successor to the older telecommunications access methods, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Discretionary Access Control
In computer security, discretionary access control (DAC) is a type of access control defined by the Trusted Computer System Evaluation Criteria (TCSEC) as a means of restricting access to objects based on the identity of subjects and/or groups to which they belong. The controls are discretionary in the sense that a subject with a certain access permission is capable of passing that permission (perhaps indirectly) on to any other subject (unless restrained by mandatory access control). Discretionary access control is commonly discussed in contrast to mandatory access control (MAC). Occasionally, a system as a whole is said to have "discretionary" or "purely discretionary" access control when that system lacks mandatory access control. On the other hand, systems can implement both MAC and DAC simultaneously, where DAC refers to one category of access controls that subjects can transfer among each other, and MAC refers to a second category of access controls that imposes constr ...

London Life Insurance
The London Life Insurance Company was a Canadian life insurance company that existed from 1874 to 2020. In 1997, London Life was acquired outright by Great-West Lifeco, the holding company of the Great-West Life Assurance Company, headquartered in Winnipeg. Great-West Lifeco had since 1969 been controlled by the Power Corporation of Canada. In 2003, Lifeco acquired Canada Life, thus bringing three of the country's largest life insurers under its control. Through the 2000s and 2010s, Lifeco ran the three insurance companies effectively as one, though they retained separate corporate identities. On 1 January 2020, Lifeco merged the three companies under the Canada Life name. History Formation of the company On 24 March 1874, the ''Act to incorporate the London Life Assurance Company'' received Royal Assent in the Parliament of Ontario.
