## Abstract

A data model for managing identity and access management (IAM) data implemented at an electronic database may include a set of logical resource elements, a set of physical resource elements, and a set of access requests elements that respectively model logical resources, physical resources, and access requests received at an access request manager of an enterprise. The physical resource elements may be respectively associated with the logical resource elements such that access rights for the physical resources may be obtained based on a logical resource specified in the access request. A system for managing IAM may include a mapping module configured to transform heterogeneous IAM data provided by a plurality of IAM data sources into homogeneous IAM data formatted according to the common IAM data format. A data store may implement the IAM data model such that the data store is configured to store the homogeneous IAM data.

## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority to Provisional Patent App. No. 61/740,205 filed on Dec. 20, 2012 and entitled “COMMON DATA MODEL FOR IDENTITY ACCESS MANAGEMENT DATA,” which is incorporated in its entirety in the present disclosure.


TECHNICAL FIELD
Aspects of the disclosure provided generally relate to identity and access management and in particular relates to management of identity and access management data using a common data model.
BACKGROUND
Identity and access management (IAM) refers to the processes, technologies, and policies for managing digital identities and controlling how identities can be used to access resources. Resources may refer to computer systems including the hardware and software components that make up the computer systems or a network of computer systems. For example, resources may include information systems, applications, services, programs, computing devices (e.g. servers, PCs), network devices (e.g. switches and routers, networks, files, file systems, databases and database objects (e.g. tables, views, and stored procedures), and the like.
Organizations may utilize various IAM products and services to implement IAM processes, which include authentication, access, and auditing. Authentication refers to verifying identities based on one or more credentials in order to gain access to a resource; access refers to managing login accounts, providing access rights to resources, and authorizing the use of resources; and auditing refers to validating and testing authentication and access capabilities.
IAM products and services may maintain event logs that include information about events that occurred during the authentication, access, and auditing processes. Event information may include, for example, the date and time of the event, the resource at which the event occurred, and other information that identifies and categorizes the event. In this regard, the event log data generated by IAM technologies and services may be referred to as IAM data.
Organizations are increasingly interested in performing large scale data analysis on the IAM data generated by IAM products and services. Analysis of IAM data can be useful, for example, to demonstrate compliance with regulatory requirements. Analysis of IAM data can also be useful to preemptively identify threats to the resources of the organization, e.g., from malware operating with the computing systems of the organization. More generally, analysis of IAM data may enable an organization to improve the efficiency and effectiveness of its IAM policies and procedures.
IAM products and services, however, may generate and store IAM data in unique or proprietary formats. IAM data stored in unique or proprietary formats may not be compatible with the formats required by various data analysis tools. To utilize the analytical tools to perform data analysis on the IAM data, a point-to-point mapping between the unique IAM data format and the format required by the data analysis tool may be necessary. Accordingly, organizations may not be able to integrate uniquely formatted IAM data for large scale data analysis of the integrated IAM data at a data analysis tool.
Therefore a need exists for a common data model for IAM data in the IAM domain.

DETAILED DESCRIPTION
Aspects of the disclosure related to identity and access management (IAM). Identity and access management may alternatively be referred to as identity management (IdM) as well as access and identity management (AIM). As noted above, a common data model for the identity and access management domain is needed. The common IAM data model described below provides a mapping for IAM elements and the relationships between those IAM elements such that uniquely formatted IAM data originating at different sources may be integrated and subsequently analyzed. The IAM data may include identity data compiled during the authentication process, access data compiled during the access process, and event data for events occurring during other IAM processes.
An IAM data source may be any resource utilized to implement IAM processes, policies, or procedures. Examples of IAM data sources that implement IAM processes, policies, or procedures include, for example, a Resource Access Control Facility, an Active Directory service, and a Security Intelligence and Risk Management (SIRM) platform. Each of these IAM technologies may generate and compile IAM data in a unique or proprietary format.
Because these technologies are each utilized to implement IAM processes, however, the IAM data generated by these technologies are semantically related or semantically equivalent within the IAM domain. The common data model provided maps this semantically related data to a common IAM data format such that IAM data across IAM technologies may be subsequently integrated and analyzed.
Referring to FIG. 1, an example of an IAM data processing system 100 that includes a common IAM data model 102 is shown. The IAM data model 102 may be implemented at a data storage device 103, e.g. at a database as a set of database tables with corresponding fields and relationships.
Multiple IAM data sources 104, 106, 108 may generate uniquely formatted IAM data 110, 112, 114 during an IAM process. Data mapping modules 116, 118, 120 may be configured to transform the uniquely formatted IAM data 110, 112, 114 into commonly formatted IAM data 122, 124, 126 that conforms to the common IAM data model 102. As seen in FIG. 1, each data mapping module 116, 118, 120 may be respectively configured to map IAM data from a particular IAM data source 104, 106, 108 in order to obtain the commonly formatted IAM data 122, 124, 126.
As shown by way of example, data mapping module 116 may be configured to transform uniquely formatted IAM data 110 into commonly formatted IAM data 122; data mapping module 118 may be configured to transform uniquely formatted data 112 into commonly formatted IAM data 124; and data mapping module 120 may be configured to transform uniquely formatted IAM data 114 into commonly formatted IAM data 126.
Having transformed the uniquely formatted IAM data 112, 114, 116 into commonly formatted IAM data 122, 124, 126, the data store 103 may store the commonly formatted IAM data. The IAM data processing system 100 may integrate the commonly formatted IAM data stored at the data store 103 to obtain integrated IAM data 128. Analytical tools may thus perform data analysis on the integrated IAM data 128 collectively rather than on the uniquely formatted IAM data 110, 112, 114 individually. In this way, the analytical tools may perform large scale data analysis on IAM data originating from multiple IAM data sources.
The IAM data processing system 100 thus avoids having to convert the uniquely formatted IAM data 110, 112, 114 from each IAM data source 104, 106, 108 in a point-to-point fashion. Instead, a single data mapping module 130 may transform the integrated IAM data 128 into IAM data 132 having a format required by an analytical tool 134. Various analytical tools may be selectively employed to analyze the integrated IAM data 128, e.g., using business analytics and business intelligence software.
The system 100 may also be employed to manage access to physical resources 136 and logical resources 138 of an enterprise (e.g., a corporation). Accordingly, the system may also include an access request manager 140 for receiving and processing access requests. The IAM data model 102 may model and create associations between the logical resources 138 and the physical resources 136. The access request manager 140 may initiate provisioning of access rights to logical resources 138 and physical resources 136 in response to receipt of an access request. Further, the access request manager may provision access rights and entitlements based on a physical permission specification 142. Access requests will be discussed in further detail below.
FIG. 2 illustrates a block diagram of an IAM data processing module/device 201 (e.g., a computer server) in an IAM data processing system 200 that may be used according to an illustrative embodiment of the disclosure. The device 201 may have a processor 203 for controlling overall operation of the IAM data processing module 201 and its associated components, including RAM 205, ROM 207, input/output (I/O) module 209, and memory 215.
I/O 209 may include a microphone, keypad, touch screen, and/or stylus through which a user of the enhanced backup and retention management module 201 may provide input, and may also include one or more of a speaker for providing audio output and a video display device for providing textual, audiovisual and/or graphical output. Software may be stored within memory 215 and/or storage to provide instructions to processor 203 for enabling device 201 to perform various functions. For example, memory 215 may store software used by the device 201, such as an operating system 217, application programs 219, and an associated database 221. Processor 203 and its associated components may allow the device 201 to run a series of computer-readable instructions to process IAM data. For instance, processor 203 may cause module 201 to extract IAM data from an IAM data source and transform the IAM data to the common IAM data format such that the IAM data conforms to the common IAM data model. In addition, processor 203 may retrieve the commonly formatted IAM data from the database 221 and transform the commonly formatted IAM data based on a format required by an analytical tool.
The server 201 may operate in a networked environment supporting connections to one or more remote computers, such as terminals 241 and 251. The terminals 241 and 251 may be personal computers or servers that include many or all of the elements described above relative to the computing device 201. The network connections depicted in FIG. 2 include a local area network (LAN) 225 and a wide area network (WAN) 229, but may also include other networks. When used in a LAN networking environment, the server 201 is connected to the LAN 225 through a network interface or adapter 223. When used in a WAN networking environment, the server 201 may include a modem 227 or other means for establishing communications over the WAN 229, such as the Internet 231. It will be appreciated that the network connections shown are illustrative and other means of establishing a communications link between the computers may be used. The existence of any of various well-known protocols such as TCP/IP, Ethernet, FTP, HTTP and the like is presumed.
Additionally, an application program 219 used by the IAM data processing module 201 according to an illustrative embodiment of the disclosure may include computer executable instructions for invoking functionality related to extracting IAM data from IAM sources and mapping the extracted IAM data to the common IAM data model.
IAM data processing module 201 and/or terminals 241 or 251 may also be mobile terminals, such as smart phones, personal digital assistants (PDAs), and the like, including various other components, such as a battery, speaker, and antennas (not shown).
The disclosure is operational with numerous other general purpose or special purpose computing system environments or configurations. Examples of well-known computing systems, environments, and/or configurations that may be suitable for use with the disclosure include, but are not limited to, personal computers, server computers, hand-held or laptop devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, and distributed computing environments that include any of the above systems or devices, and the like.
The disclosure may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, and the like. that perform particular tasks or implement particular abstract data types. The disclosure may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked, for example, through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.
Referring to FIG. 3, a flowchart 300 of example method steps for processing IAM data in accordance with the common IAM data model is shown. The common IAM data model may be implemented at a data store that stores IAM data conforming to the common IAM data model (step 302). The IAM data model may be implemented at a data modeling tool. The data modeling tool may be configured to generate data definition language (DDL) for implementing the common IAM data model at a data store, e.g., a database. The DDL may define the database schema that corresponds to the common IAM data model, and a database management system may use the DDL to create the database tables and columns that correspond to the common IAM data model.
IAM data may be retrieved from an IAM data source (step 304). Various tools may be selectively employed to extract the IAM data from the IAM data sources, e.g., data integration software. A data mapping module may map the uniquely formatted IAM data to the common IAM data model (step 306). Multiple data mapping modules may be employed to respectively map IAM data extracted from multiple IAM data sources. In this way, uniquely formatted IAM data from multiple sources is transformed to a common IAM data format, e.g., the common IAM data format defined by the common IAM data model described in this disclosure.
Having mapped the extracted IAM data to the common IAM data format, the commonly formatted IAM data may be stored in the data store that implements the common IAM data model (step 308). If additional IAM data sources remain (step 310), then steps 304-308 may be repeated to retrieve uniquely formatted IAM data from another IAM data source, map the uniquely formatted IAM data to the common IAM data model, and store the transformed commonly formatted IAM data in the data store that implements the common IAM data model.
The common IAM data model thus permits the combination and integration of IAM data from different IAM data sources. Once the commonly formatted IAM data has been stored in the data storage device, the IAM data is available for subsequent processing as needed, e.g., for large scale data analysis.
To perform data analysis, commonly formatted IAM data may be retrieved from the data storage device (step 312). The commonly formatted IAM data retrieved from the data store may be IAM data integrated from multiple IAM data sources. A data mapping module may transform the commonly formatted IAM data to a format required by an analytical tool (step 314). The analytical tool may thus perform data analysis on the integrated IAM data that originated from multiple IAM data sources as uniquely formatted IAM data (step 316).
An enterprise (e.g., a business) may also utilize the common IAM data model to manage access rights to various resources of the business. FIG. 4 is a flowchart 400 of example method steps for managing IAM data at an enterprise. A common IAM data model may be implemented at a data store, e.g., a database (block 402). The common IAM data model may be, for example, the common IAM data model described in this disclosure. The logical resources and physical resources of an enterprise may be identified (block 404). Logical resources may be associated with corresponding physical resources using the IAM data model implemented at the data store (block 406), e.g., via database records. Logical and physical resources will be discussed in further detail below. Enterprise engineers, business managers, information technology personnel, and other individuals associated with the enterprise may, for example, be responsible for identifying and modeling the logical resources and physical resources at the data store that implements the IAM data model.
Profiles and roles associated with the enterprise may be identified and modeled using the IAM data model implemented at the data store (block 408), e.g., by adding and updating database records corresponding to and associated with the profile and roles. Business tasks, activities, processes, and functions may be identified and also modeled using the IAM data model implemented at the data store (block 410), e.g., database records corresponding to the business tasks, activities, processes, and functions may be created, updated, and related at the database implementing the IAM data model. For example, business tasks may be associated with business activities using the IAM data model implemented at the data store (block 412). Additionally, business processes may be associated with business activities using the IAM data model implemented at the data store (block 414). Further, business functions may be associated with business processes using the IAM data model implemented at the data store (block 416). Moreover, business activities may be associated with logical permissions using the IAM data model implemented at the data store (block 418). Job functions may be identified and modeled using the IAM data model implemented at the data store (block 420), e.g., by adding and updating database records corresponding to and associated with the job functions. Job functions may be associated with business activities using the IAM data model implemented at the data store (block 422). Business managers may, for example, be responsible for identifying and modeling profiles and roles as well as the business tasks, activities, processes, and functions of the enterprise.
Having identified, modeled, and associated resources, job functions, and business tasks, activities, processes, and functions, access to those resources may be provisioned based on a particular job function or business task, activity, process, or function. Accordingly, an access request manager may receive an access request regarding a logical resource (block 424). The access request manager may identify the logical resource indicated in the access request (block 426) and identify one or more physical resources that correspond to the logical resource (block 428). The access request manager may thus initiate provisioning of physical entitlements to the physical resources corresponding to the logical resource (block 430) and obtain physical permissions to those physical resources (block 432). Obtaining the physical permissions may include translating logical permissions into physical permissions based on a physical permission specification associated with the logical resource (block 434). Once the access information has been provisioned, the access request manager may provide the access information for the logical resource to a user (block 436). Access requests will be discussed in further detail below.
In FIGS. 5-26 various diagrams that illustrate portions of an IAM data model are shown. Those skilled in the art will recognize that the IAM data model organizes IAM concepts into attributes, elements, and relationships using what may be referred to as an element-relationship (ER) diagram, also known as an entity-relationship diagram. It will be appreciated, however, that because the IAM domain employs the term “entity” in an IAM context, the ER diagram described in this disclosure will be referred to as an “element-relationship” diagram for the purpose of clarity. When implemented at a database, the elements, attributes, and relationships may equate to tables, columns, and relationships in the database (e.g., a relational database). Furthermore, those skilled in the art will recognize the notations used in the figures as establishing respective relationships between the various elements of the ER diagram including, e.g., inheritance relationships as well as one-to-one (1:1), zero-to-one (0:1), one-to-many (1:M), zero-to-many (0:M), and many-to-many (M:M) relationships. Some of the diagrams include attributes that identify and describe the elements and relationships. One or more attributes may be employed as a primary key (i.e., unique key) to uniquely identify an instance of an element or a relationship (e.g., a row in a database table). Attributes may also be employed as foreign keys to establish the relationships between elements. In the ER diagram for the IAM data model, primary keys and foreign keys are underscored (i.e., underlined).
Referring now to FIGS. 5-10, summary views of an example of an IAM data model are shown. In FIG. 5, a portion 500 of an example IAM data model relating to resources, accounts, physical entitlements, profiles, and roles is shown. A resource (e.g., a system resource) may be a computer system including any hardware and software components as well as a network of computer systems. Resources may include information systems, applications, services, programs, computing devices (e.g. servers, PCs), network devices (e.g. switches, routers, networks, files, file systems, databases, and database objects such as tables, views, and stored procedures). A resource manager may be an operating system level or an application level function that manages access to one or more resources. Resource managers may include an operating system file manager that manages access to files and file systems, a database management system (DBMS) that manages access to database tables and views and an application using application level security to control access to application programs. A resource manager may manage one or more resources. Accordingly, a resource may be associated with the resource manager that manages the resource. A resource manager may be associated with one or more user accounts.
A user may be anything identified on a system or a network. Users may include, for example, associates and customers that access bank systems. A resource manager may issue user accounts to users in order to manage access to the resources associated with the resource manager. One example of a user account may be a server login account that provides access to a server. The user account, in this example, may or may not provide access to other resources associated with the server such as files stored at the server. A resource manager may assign an access identifier to a user account, e.g., an identifier for a directory service.
Access refers to the ability of a user to perform an action on a resource. Examples of access rights include, for example, create, read, update, delete, and execute. An access right refers to the authority to perform types of access such as reading or writing to a file. Entities may include, for example, individuals, organizations, and even other resources. Individuals and organizations may be collectively referred to as parties (e.g., parties to a contract).
A system identifier refers to an identifier for an individual or for a resource in a computing environment. An identifier for a resource may be referred to as a service ID. An Individual as well as a service ID may be associated with a system identifier that may be related to many user accounts. A user account may allow the associated the individual or service ID to access one or more of the resources controlled by a resource manager. In some implementations, a resource may be controlled by multiple resource managers. When an individual or service ID needs to access resources controlled by multiple resource managers, an individual or service ID may be associated with multiple user accounts. User accounts may include a single sign-on account that manages the login process on behalf of other accounts. A single sign on manager is a type of resource manager.
A group may be a container for multiple user accounts and for other groups. A group may, for example, be associated with both user accounts and other groups. A group may also be assigned an access ID. Identifiers for user and groups may share a common set of access IDs. A group may be composed entirely of other groups or of both user accounts and groups. Groups may be nested for any number of levels. Related groups may contain the groups and user accounts that are members of each group.
A physical permission may be a set of one or more access rights to resources. Physical permissions may include, for example, the authority to execute server transactions; authority to read a file, authority to update a database table, and the like. A physical entitlement with respect to an access control list (ACL) may be a combination of a physical permission and a user account (or group). In this way, entitlements may be associated with user account or a group as well as with groups nested within groups. A physical entitlement may serve as the basis for run-time authorization decisions. A profile may be the named collection of permissions, e.g., physical permissions. Rule profiles may be based on job codes or job categories. A physical entitlement with respect to role based access control (RBAC) may be a set of user accounts (or groups) associated with a profile. A physical entitlement based on RBAC may be a set of one or more user accounts (or groups) associated with a profile.
In FIG. 6, a portion 600 of an example IAM data model relating to logical resources, logical permissions, and physical permissions is shown. A logical resource, in this example, is a type of resource or a resource component that is visible or accessible to an end user. Logical resources may include, for example, end user procedures, job aids, and use cases. Logical resources may, in some cases, be implemented with resources and resource components that are not visible to an end user. One example of a logical resource may be a screen used by an end user to maintain customer accounts. A server transaction that invokes the screen may be a resource associated with the logical resource but may not be visible to the end user. Logical resources may correspond to or be associated with one or more physical resources. In this example, Logical Resource To Resource contains combinations of logical resources and corresponding physical resources. The relationship between logical resources and physical resources, in this example, is modeled as a many-to-many relationship such that a logical resource may be implemented by many physical resources and such that a physical resource can be implement many logical resources.
A permission may be a set of one or more access rights to one or more logical or physical resources. Permissions may include, for example, access rights to use a particular screen (i.e., a logical resource), access rights to execute a particular application, access rights to delete a row in a database table, and the like. A logical permission may be a set of one or more access rights to one or more logical resources. Logical permissions may include, for example, the ability to access and use customer maintenance screens in order to maintain customer accounts. The IAM data model, in this example, establishes the Logical Permission element as a subtype of Permission. The Logical Permission element may identify a particular logical permission. A logical permission may be associated with multiple combinations of access rights to logical resources. The Logical Permission To Access Rights And Logical Resources element, in this example, associates pairings of access rights and logical resource to a particular logical permission. The IAM data model, in this example, also establishes the Physical Permission element as a subtype of Permission. The Physical Permission To Access Rights And Resources element, in this example, relates a physical permission to combinations of access rights and resources that are deployed on target platforms and used for access decisions at run-time.
A logical permission may be translated into a physical permission that can be deployed to a target platform. A physical permission specification may employed to translate a logical permission to zero, one, or multiple physical permissions. One example includes mapping server transaction codes utilized to execute a set of customer maintenance screens that are defined as logical resources. A logical resource may be associated with a corresponding physical permission specification. A physical permission specification may be associated with pairs of access rights and resources. In this way, logical resources may appear to be seamlessly integrated to a user but involve relationships between multiple physical resources on multiple platforms. The IAM data model, in this example, also establishes the Physical Permission Specification element as a subtype of Permission. The Physical Permission Specification To Access Rights And Resources element relates a specification to specific combinations of access rights and resources.
In FIG. 7, a portion 700 of an example IAM data model relating to business activities, job functions, and logical permissions, is shown. A business task may refer to a discrete unit of work having an associated set of inputs and outputs. One example of a business task includes the review of a loan form submitted by a customer for completeness and to verify customer name and address information on the form. A business activity may refer to a set of business tasks having a specific inputs and outputs for a particular business purpose. One example of a business activity includes loan origination, which may include includes many business tasks such as assisting a customer in preparing a loan form, reviewing the loan form for completeness, verifying customer account information on the form, and verifying any information not in the account records. Because a business task may be a discrete unit of work, a business task may be associated with many business activities and a business activity may be associated with many business tasks. To continue the example above, verifying customer account information may be associated with other business activities beyond loan origination. A business process may refer to a set of one or more steps designed to produce a product or service. Proceeding from loan origination thru close in an example of one business process that may include multiple business activities such as, e.g., loan origination, credit checking, and preparing closing documents. A business process may span multiple business functions. For example, a loan origination office may manage multiple individuals performing a portion of the process.
An individual performing a business activity may need access to one or more logical resources (e.g. screens and reports). The Business Activity To Logical Permission element may associate business activities to logical permissions (i.e. access rights to logical resources). A logical resource may be utilized by multiple business activities (e.g. an account lookup screen), and a business activity may utilize multiple logical resources (e.g. screen to request a credit report and a screen to update the customer records). A physical permission may be related to a group, in this example, via the Physical Entitlement-ACL element. A group of physical entitlements may thus be associated with a business activity, in this example, via the Business Activity To Group element.
A job function may be a collection of related business activities. An individual may be associated with a job function. One example of a job function includes a teller at a bank where the teller may perform multiple business activities such as, e.g., opening and servicing customer accounts, taking deposits, processing loan forms, and the like. Business activities may be associated with different business processes. Other examples of business processes include customer relationship management, check processing from deposit through clearing, loan origination to close. A job function may involve performing activities with within each of these business processes.
Roles may be associated with a set of entitlements, e.g., in role based access control (RBAC). The IAM data model, in this example, may associate roles with a set of entitlements that are, in turn, associated with a set of business activities. Logical permissions may be associated with a set of business activities that are, in turn, associated with a job function. The IAM data model, in this example, associates an individual with a job function, job functions with a business activities, and business activities with logical entitlements. The IAM data model, in this example, also associates an individual with a system identifier and through the system identifier to a user account. A user account may be associated with physical entitlements, which may correspond to the implementation of logical entitlements. The IAM data model, in this example, also models incompatible business activities. Incompatible business activities may be business activities where it is undesirable to have the same individual perform those business activities. For example, it may be undesirable to have an individual responsible for originating loans should to approve loans.
FIG. 8, a portion 800 of an example IAM data model relating to access requests is shown. An access request refers to a request to provision an individual with the necessary access rights, entitlements, and permissions to access a logical resource and corresponding physical resources. The IAM data model, in this example, includes an Access Request Header element and an Access Request Detail element to model access requests. The Access Request Header element, in this example, includes an access request status, the user account of the requestor, the user account or group of the requestee, the access request resource.
The Access Request Detail element may permit a single access request to support many different actions on many different types of requests. The IAM data model, in this example, models five types of access requests, although it will be appreciated that additional or alternative types of access requests may be employed. Access request types may include, e.g., an access request by job function, an access request by business activity, an access request by business unit, an access request by logical permission, and an access request by physical permission specification. An access request detail may be associated with an access request detail action. The Access Request Detail Action Type element may contains a set of actions associated with an access request (e.g. add, suspend, and revoke).
Access request details may be associated with one or more events that include approvals and physical completion of items. The Access Request Detail Event Type element may include the domain of valid event types. The Access Request Detail Item Event History element may include the date time history of respective events.
FIG. 9, a portion 900 of an example IAM data model relating to access requests with respect to job functions and logical permissions is shown. The IAM data model permits an alternative approach to RBAC. The IAM data model leverages the business architecture concept that describes the business in terms business process composed of business activities and business tasks. As discussed above, job functions may be a collection of pre-defined business activities and may correspond to roles with respect to RBAC, and logical permissions may be access rights to resources visible to the business. When an individual performs a business activity, the individual may need to access various resources of the business, e.g., particular software applications or services. As noted above such resources may be defined as logical resources, and logical permissions may provide access to those logical resources. Logical permissions may be associated with business activities, and business activities may be associated with job functions. In this way, roles are based on the business architecture and use logical entitlements that have business meaning in the context of the business activities associated with the roles.
Job functions may be a collection of specific business activities. An individual may be assigned multiple job functions, and a job function may be associated with particular business activities. For example, a baseline job function may be set up for basic resources such as an email application and a timekeeping application. A business may assign this baseline job function to a new hire and submit an access request for these basic applications. A manager may submit subsequent access requests for other job functions based on activities performed by the new hire. For example, basic teller job function may include business activities for customer service, deposit process, safe deposit boxes, and the like. A senior teller job function may include business activities beyond the scope of responsibility for a basic teller. In this example, a senior teller may be associated with multiple job functions: the baseline job function for access to basic resources, the basic teller job function for access to resources utilized by basic tellers, and the senior teller for access to resources utilized by senior tellers.
In this way, the IAM data model advantageously streamlines the process of identifying logical resources and what job functions, business activities and the like should have access to those resources. Moreover, the IAM data model permits enterprise from dividing the process providing access into a business side and a physical side. On the business side, entitlements may be requested in business terms, and access reviews may be conducted in business terms. On the physical side, the IAM data model establishes a link between access requests in business language and the specifications to provision physical entitlements. Furthermore, a reconciliation process between the physical entitlement specifications and the entitlements provisioned may ensure that provisioned entitlements can be linked to corresponding access requests. As a result, the business may advantageously operate in business terms without regard to the entitlements ultimately provisioned in physical terms. Additionally, access reviews may be performed in the same language as access requests, that is, in terms of job functions, business activities, and logical permissions. Access requests may be provisioned as physical entitlements, and a reconciliation process may allow access reviews to be performed in business terms without referring to the underlying physical entitlements.
FIG. 10 a portion 1000 of an example IAM data model relating to access requests with respect to job functions and physical permissions is shown. In this example, an individual may be hired and assigned one or more job functions (Person To Job Function). The assigned job function may be associated with one or more business activities (Job Function To Business Activity). A business activity may be associated with logical permissions, that is, access rights defined in terms of logical resources (Business Activity To Logical Permission). These are the logical resources and access rights to the logical resource the individual may need to carry out the business activity. Logical resources may be associated with physical resources (Logical Resource To Resource).
An access request (Access Request) may be generated using the user account associated with the individual (Person→System Identifier→User Account) and a job function. The access request may be associated with a the Access Request element and one of the elements corresponding to a subtype of access request, e.g., the Access Request by Job Function element. Access request subtypes may include other attributes specific to each subtype of access request.
Business level access reviews may thus be conducted in terms of the logical permissions associated with an employee via the job function associated with the employee and the business activities associated with the job function. A manager may thus request logical permissions and perform reviews of approved access requests and associated logical entitlements.
Those skilled in the art will appreciate, with the benefit of the approach set forth above with respect to access requests by job function, that similar approaches may be employed with respect to access requests by business activity, access requests by business unit, access requests to particular logical resources, and access requests to particular physical resources. The example IAM data model set forth in FIGS. 11-26 may be implemented and utilized to manage these additional types of access requests.
