Overview
ISO/IEC 24760-1:2019/Amd 1:2023 is an internationally recognized amendment to the ISO/IEC 24760-1:2019 standard, issued by ISO and IEC. It focuses on enhancing the framework for identity management within the domain of IT security and privacy. This amendment updates key terminology and concepts related to identity management, addressing evolving security requirements and technological innovations.
The standard is critical for organizations aiming to establish robust identity management systems that ensure secure, reliable authentication and authorization. It defines foundational terms such as authenticators, authentication factors, and access tokens, which are essential in safeguarding digital identities and controlling access to resources.
Key Topics
Readily-verifiable Identifier
An identifier designed to be easily validated as belonging to a known entity, supporting efficient authentication processes.
Example: A digital signature derived from solving a cryptographic puzzle.Authoritative Identifier
A unique identifier issued by a trusted authority within a well-established domain, such as government-issued IDs, ensuring high trust in identity verification.Access Token
A trusted object encapsulating permissions that authorize a principal’s access to resources, often obtained after successful authentication. It can be either physical or virtual and may contain cryptographic information to verify its integrity.Authentication Factors
Four types are recognized to enhance authentication security:- Cognition factor: What the principal knows (e.g., a password).
- Possession factor: What the principal holds (e.g., a security token).
- Inherent factor: Physical characteristics (e.g., fingerprint).
- Behaviour factor: Typical actions or patterns (e.g., typing rhythm).
Multi-factor Authentication
Employs two or more authenticators from different authentication factors to increase security assurance.Authenticator
A secure device or software representing an entity in the authentication process, controlled by the principal. Examples include OTP generators, mobile authentication apps, and electronic identity cards.One-Time Password (OTP)
A single-use, randomly generated password for authentication, typically produced by an authenticator.Personal Secret
Exclusive knowledge to the principal, such as passwords or PINs, used for identity validation.Entity Authentication Assurance & Level of Assurance
These define the reliability and strength of confidence in identity assertions, guiding organizations in selecting appropriate authentication methods per risk level.Principal’s Personal Identity Management System (PPI)
An identity management system held under exclusive control by the principal, often implemented as a mobile identity or dedicated token.
Applications
ISO/IEC 24760-1:2019/Amd 1:2023 serves as a foundational reference for designing and implementing identity management solutions that prioritize IT security and privacy. Key application areas include:
Enterprise Identity and Access Management (IAM)
Establishing reliable and standardized identity verification across corporate resources.Government Identity Programs
Supporting secure issuance and management of authoritative identifiers used in digital government services.Multi-factor Authentication Deployment
Enhancing user authentication security by integrating authenticators across various authentication factors.Digital Identity Wallets and Mobile Identity Solutions
Guiding the creation of personal identity management systems that empower users with control over their digital identities.Secure Access Control Systems
Implementing access tokens and assurance levels to fine-tune access privileges in cloud services, applications, and IoT devices.
Organizations benefit by aligning with this standard to improve interoperability, compliance with data protection regulations, and resilience against identity fraud.

3.2
Add the following term:
3.2.5
access token
trusted object encapsulating the authority for a principal to access a resource
Note 1 to entry: An access token can be obtained in the result of an authentication.
Note 2 to entry: An access token may contain access permission information for a subject to access the resource

3.3
Add the following entries:
3.3.9
authentication factor
distinguishing feature of an authenticator to characterise its use in authentication
Note 1 to entry: Four different authentication factors can be recognized:
— cognition factor, any credential that is formed by something that the principal knows and can reproduce
(exclusively): a personal secret;
— possession factor, any credential that is formed by something that the principal possesses, e.g. an authenticator;
— inherent factor, any credential that is formed by a description of something that is inherent to the physical
existence of the principal, e.g. a biometric characteristic such as fingerprint, facial image, or 1, iris pattern;
— behaviour factor, any credential that is formed by a description of something that the principal typically
does, e.g. a behaviour pattern.
3.3.10
multi-factor authentication
authentication in which multiple authenticators are used of two or more authentication factors
Note 1 to entry: If two or more authenticators are being used in authentication that have the same authentication
factor, they should have been issued by different credential issuers.
Note 2 to entry: Using multiple authenticators (that differ in authentication factor can enhance the security of the
authentication as that could prompt the principal to act differently with each of them.
