Account Takeover Account takeover is a form of identity theft and fraud, where a malicious third party successfully gains access to a user’s account credentials. Designing MFA for Humans
Accountability The obligation of a person to accept the results of one’s actions, be they positive or negative. This person is probably also a species of an owner. Introduction to Access Control
Adaptive Authentication Adaptive authentication aims to determine and enforce the authentication level required at any time during a user session - when the session is commenced, during the session when access requirements force a re-evaluation, or when the session token expires. The factors to be used in achieving that authentication level are determined dynamically based on the access control policy governing the resources being accessed, and a variety of environmental conditions and risk factors in effect at that time for that user. Designing MFA for Humans
Agile Project Management A framework that uses a continuous, iterative process to deliver a defined piece of functionality, typically a component of a product or service. Scrum is a popular framework ( https://www.scrumalliance.org/about-scrum/overview ) Introduction to IAM Project Management

Data Controller Defined in Article 4(7) of the GDPR: “‘controller’ means the natural or legal person, public authority, agency or other body which, alone or jointly with others, determines the purposes and means of the processing of personal data;”. This article uses the term “organisation” as a synonym for “data controller”, since organisations involved in IAM will normally be data controllers. An Introduction to the GDPR
Data Mapping “a system of cataloguing what data you collect, how it’s used, where it’s stored, and how it travels throughout your organization and beyond.” Impact of GDPR on Identity and Access Management
Data Processor Defined in Article 4(8) of the GDPR for situations where an organisation processes personal data solely on the instructions of others. A Data Processor must not determine the purposes of processing, for example by processing in its own interests, or, beyond limited technical choices, the means of doing so. Data Processors are regulated by Article 28: in particular they must have a contract with the Data Controller that covers all the subjects listed in Article 28(3). Data Processors are excluded from some, but not all, of the liabilities and duties of Data Controllers. An Introduction to the GDPR
Data Protection by Design Data protection through technology design. See GDPR Article 25 for more detail Impact of GDPR on Identity and Access Management
Data Protection Officer An individual who must be appointed in any organization that processes any data defined by the GDPR as sensitive. The DPO is responsible for “Working towards the compliance with all relevant data protection laws, monitoring specific processes, such as data protection impact assessments, increasing employee awareness for data protection and training them accordingly, as well as collaborating with the supervisory authorities.”(See GDPR Articles 35, 37, 38, and 39 for more detail) Impact of GDPR on Identity and Access Management
Data Subject Defined in Article 4(1) of the GDPR (see “Personal Data” above) as the formal term for the human to whom personal data relates. This article uses the term “individual” as a synonym for “data subject”. An Introduction to the GDPR

Digital Wallet represents a digital metaphor for a physical wallet and is generally represented by the combination of the user agent and the underlying capabilities of the computing device, such as secure storage and secure enclaves on a mobile phone. The digital wallet contains digital cards. A Peek into the Future of Decentralized Identity
dPKI A decentralized public key infrastructure and is usually implemented via an immutable blockchain or ledger – a place where DIDs can be registered and looked up alongside the associated public keys of the DID and its metadata. dPKI can be described more generally as the verifiable data registry , as the dPKI is just one of many possible implementations for a verifiable data registry. While this paper refers to dPKI, the reader should be aware that a verifiable data registry need not necessarily be “decentralized”. A Peek into the Future of Decentralized Identity

Identification Uniquely establish a user of a system or application. Introduction to Access Control
Identity Defining attributes for a human user that may vary across domains, e.g., a user’s digital identity will have a different definition in a work environment as opposed to the user’s bank. A device identifier is sometimes referred to as its identity. Non-Human Account Management
Identity Governance and Administration (IGA) Includes the collection and use of identity information as well as the governance processes that ensure the right person has the right access to the right systems at the right time. Introduction to IAM Architecture
Identity Hub or Repository The place where users can store their encrypted identity-related information. An identity hub can be anywhere – on the edge, on the cloud, or on your own server. Its purpose is to store personal data. Some implementations may allow other entities to access the identity hub of the user if the user specifically grants such access. You can think of an identity hub as the individual’s personal data store. A Peek into the Future of Decentralized Identity
Identity Theft Law Laws governing crimes in which the perpetrator gains access to sensitive personal information belonging to the victim (such as birth dates, passwords, email addresses, driver's license numbers, social security numbers, financial records, etc.), and then uses this information to impersonate the victim for personal gain, such as to commit fraud, establish credit in the victim’s name, or access the victim’s accounts. Laws Governing Identity Systems

Privacy Law Laws that regulate the collection, use, storage, and transfer of personal data relating to identified or identifiable individuals. Laws Governing Identity Systems
Processing Defined in Article 4(2) of the GDPR: “‘processing’ means any operation or set of operations which is performed on personal data or on sets of personal data, whether or not by automated means, such as collection, recording, organisation, structuring, storage, adaptation or alteration, retrieval, consultation, use, disclosure by transmission, dissemination or otherwise making available, alignment or combination, restriction, erasure or destruction”. Note that even this long list of activities is not exhaustive: other activities may also fall within the definition of “processing”. Additional rules, in Article 22, apply to “automated individual decision-making, including profiling”.

Special Category Data (SCD) Categories of data that are regarded as particularly sensitive, so subject to additional regulation. Defined in Article 9(1) of the GDPR as “personal data revealing racial or ethnic origin, political opinions, religious or philosophical beliefs, or trade union membership, and the processing of genetic data, biometric data for the purpose of uniquely identifying a natural person, data concerning health or data concerning a natural person’s sex life or sexual orientation”; Article 10’s “personal data relating to criminal convictions and offences” requires similar treatment, so is normally considered as another category of SCD. An Introduction to the GDPR
Step-Up Authentication A method to increase the level of assurance (or confidence) the system has regarding a user’s authentication by issuing one or more additional authentication challenges, usually using factors different from the one(s) used to establish the initial authenticated session. The need for increasing the level of assurance is typically driven by the risk associated with the sensitive resource the user is attempting to access. Designing MFA for Humans
System Account A generic term for a privileged account that has extensive permissions to system-level functions, typically used to install new applications, perform system updates, or make configuration changes. Non-Human Account Management
Task Lowest level of defined activity; multiple tasks will typically be grouped into stages of project phases Intro to Project Management
