Identity management ( IdM ), also known as identity and access management ( IAM or IdAM ), is a framework of policies and technologies to ensure that the right users (that are part of the ecosystem connected to or within an enterprise) have the appropriate access to technology resources.
The UID, along with the group identifier (GID) and other access control criteria, is used to determine which system resources a user can access. The password file maps textual user names to UIDs. UIDs are stored in the inodes of the Unix file system, running processes, tar archives, and the now-obsolete Network Information Service.
SSO is a subset of federated identity management, as it relates only to authentication and technical interoperability. Centralized identity management solutions were created to help deal with user and data security where the user and the systems they accessed were within the same network – or at least the same "domain of control".
Single sign-on ( SSO) is an authentication scheme that allows a user to log in with a single ID to any of several related, yet independent, software systems. True single sign-on allows the user to log in once and access services without re-entering authentication factors.
View history. System for Cross-domain Identity Management ( SCIM) is a standard for automating the exchange of user identity information between identity domains, or IT systems. One example might be that as a company onboards new employees and separates from existing employees, they are added and removed from the company's electronic employee ...
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.
A personal identification number ( PIN ), or sometimes redundantly a PIN number or PIN code, is a numeric (sometimes alpha-numeric) passcode used in the process of authenticating a user accessing a system.
