[1] Originally called RACF it was renamed to z/OS Security Server (RACF), although most mainframe folks [who?] still refer to it as RACF. [2] Its main features are: [1]
In computers, logical access controls are tools and protocols used for identification, authentication, authorization, and accountability in computer information systems.

The Underwriters Laboratories' UL 294 is a safety standard that addresses the construction, performance, and operation of access control systems intended to regulate or control entry into and exit from secured areas. These systems can also restrict access to certain devices through electrical, electronic, or mechanical means.
Attribute-based access control (ABAC), also known as policy-based access control for IAM, defines an access control paradigm whereby a subject's authorization to perform a set of operations is determined by evaluating attributes associated with the subject, object, requested operations, and, in some cases, environment attributes.
In computer security, general access control includes identification, authorization, authentication, access approval, and audit.A more narrow definition of access control would cover only access approval, whereby the system makes a decision to grant or reject an access request from an already authenticated subject, based on what the subject is authorized to access.
Distributed Access Control System (DACS) [1] is a light-weight single sign-on and attribute-based access control system for web servers and server-based software.DACS is primarily used with Apache web servers to provide enhanced access control for web pages, CGI programs and servlets, and other web-based assets, and to federate Apache servers.
