Identity management, otherwise known as identity and access management (IAM) is an identity security framework that works to authenticate and authorize user access to resources such as applications, data, systems, and cloud platforms. It seeks to ensure only the right people are being provisioned to the right tools, and for the right reasons.
Authentication (from Greek: αὐθεντικός authentikos, "real, genuine", from αὐθέντης authentes, "author") is the act of proving an assertion, such as the identity of a computer system user. In contrast with identification, the act of indicating a person or thing's identity, authentication is the process of verifying that identity.
In an e-authentication model, a claimant in an authentication protocol is a subscriber to some CSP. At some point, an applicant registers with a Registration Authority (RA), which verifies the identity of the applicant, typically through the presentation of paper credentials and by records in databases. This process is called identity proofing.
Zero trust architecture (ZTA) or perimeterless security is a design and implementation strategy of IT systems. The principle is that users and devices should not be trusted by default, even if they are connected to a privileged network such as a corporate LAN and even if they were previously verified.
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.
Mobile authentication is the verification of a user's identity through the use a mobile device. It can be treated as an independent field or it can also be applied with other multifactor authentication schemes in the e-authentication field. [29] For mobile authentication, there are five levels of application sensitivity from Level 0 to Level 4.
An authenticator is a means used to confirm a user's identity, [1] [2] that is, to perform digital authentication. A person authenticates to a computer system or application by demonstrating that he or she has possession and control of an authenticator. [3] [4] In the simplest case, the authenticator is a common password.
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. [2] The task of the authentication protocol is to specify the exact series of steps needed for execution of the authentication.
