The JupiterOne Data Model is a reference model used to describe digital resources and the complex interconnections among all the resources in a technology organization as an entity-relationship graph.
The data model is defined by a set of Entities and their Relationships. It represents a reference model, not a strict or rigid structure.
Entity 
An Entity is a node/vertex in the graph that represents a resource within your digital infrastructure.
See full data model schema in this GitHub repo.
Class and Type of an Entity
Each Entity has a specific type that defines what that entity is, and is assigned one or more higher level class that represents a more abstract categorization or labeling of the entity in the perspective of security and technical operations.
Type
The type property represents the specific type that entity is as defined by
the source. For example, an AWS resource may be of type aws_instance or
aws_s3_bucket or aws_iam_user.
Class
The class of an entity is considered an abstract, super-type that defines
what that entity is within the general framework of IT and security operations.
In the above example, an aws_instance entity has a class of Host, while
an aws_s3_bucket is a DataStore, and an aws_iam_user a User.
Common Entity Properties
Most Entities will have the following common properties.
| Property | Type | Description |

Class Specific Entity Properties
Each specific class of Entity also has its own defined properties. For example,
a Person entity will have properties including firstName and lastName,
while a Device entity may have properties such as hardwareVendor,
hardwareModel, and hardwareSerial.
Custom Properties
Entities can also have custom properties that are specific to the type of that entity, defined by the source system where the resource belongs to, or defined by the individual or team managing the resource.
Defined Entities
Here is a list of reference entities defined by the JupiterOne Data Model, each with its own defined set of properties in addition to the shared common properties:
| Entity | Description |
|---|---|
AccessKey |
A key used to grant access, such as ssh-key, access-key, api-key/token, mfa-token/device, etc. Extends the Key entity class. |
AccessPolicy |

CodeRepo |
A source code repository. A CodeRepo is also a DataRepository therefore should carry all the required properties of DataRepository. |
CodeReview |
A code review (in git, a pull request). A CodeReview is also an official Record. |
Control |
A security or IT Control. This is most likely an additional Class applied to a Service (e.g. Okta SSO), a Device (e.g. a physical firewall), or a HostAgent (e.g. Carbon Black CbDefense Agent). |
ControlPolicy |
An operational or configuration compliance policy with technical specifications / rules that governs (i.e. enforces, evaluates, or monitors) a security control or IT system. |
CryptoKey |
A key used to perform cryptographic functions, such as an encryption key. Extends the Key entity class. |
DataObject |
An individual data object, such as an aws-s3-object, sharepoint-document, source-code, or a file (on disk). The exact data type is described in the _type property of the Entity. |
DataStore |
A virtual repository where data is stored, such as aws-s3-bucket, aws-rds-cluster, aws-dynamodb-table, bitbucket-repo, sharepoint-site, docker-registry. The exact type is described in the _type property of the Entity. |
Database |
A database cluster/instance. |
Device |
A physical device or media, such as a server, laptop, workstation, smartphone, tablet, router, firewall, switch, wifi-access-point, usb-drive, etc. The exact data type is described in the _type property of the Entity. |

Host |
A system that has an operating system running on it. The exact host type is described in the _type property of the Entity. The UUID of the host should be captured in the _id property of the Entity. |
HostAgent |
A software agent or sensor that runs on a host/endpoint. |
Incident |
An operational or security incident. |
IpAddress |
An re-assignable IpAddress resource entity. Do not create an entity for an IP Address configured on a Host. Use this only if the IP Address is a reusable resource, such as an Elastic IP Address object in AWS. |

Network |
A network, such as an AWS VPC, subnet, or VLAN. |
NetworkInterface |
An re-assignable software defined network interface resource entity. Do not create an entity for a network interface configured on a Host. Use this only if the network interface is a reusable resource, such as an Elastic Network Interface object in AWS. |
Organization |
An organization, such as a company (e.g. Amazon) or a business unit (e.g. HR). An organization can be internal or external. Note that there is a more specific Vendor class. |
PasswordPolicy |
A password policy is a specific ControlPolicy. It is separately defined because of its pervasive usage across digital environments and the well known properties (such as length and complexity) unique to a password policy. |
Person |
An entity that represents an actual person, such as an employee of an organization. |
Policy |
A written policy documentation. |
Procedure |
A written procedure and control documentation. A Procedure typically IMPLEMENTS a parent Policy. An actual Control further IMPLEMENTS a Procedure. |
Project |

Record |
An official record (e.g. Risk), or a written document (e.g. Policy/Procedure), or a reference entity (e.g. Vulnerability/Weakness). This could be a jira-issue, a bitbucket-pull-request, a jenkins-build, a policy document, a vulnerability finding, a documented risk, or even a paper-record. The exact record type is captured in the _type property of the Entity. |
Resource |
A generic assignable resource. A resource is typically non-functional by itself unless used by or attached to a host or workload. |
Risk |
An object that represents an identified Risk as the result of an Assessment. The collection of Risk objects in JupiterOne make up the Risk Register. A Control may have a MITIGATES relationship to a Risk. |
Service |
A service provided by a vendor. |
Site |
The physical location of an organization. A Person (i.e. employee) would typically has a relationship to a Site (i.e. locatedat or workat). Also used as the abstract reference to AWS Regions. |
Team |
A team consists of multiple member Person entities. For example, the Development team or the Security team. |
Training |
A security training module. |
User |
A user account/login to access certain systems and/or services. Examples include okta-user, aws-iam-user, ssh-user, local-user (on a host), etc. |
UserGroup |
A user group, typically associated with some type of access control, such as a group in Okta or in Office365. If a UserGroup has an access policy attached, and all member Users of the UserGroup would inherit the policy. |
Vendor |
An external organization that is a vendor or service provider. |
Vulnerability |
A security vulnerability finding (application or system or infrastructure, e.g. a CVE). A single vulnerability may impact multiple resources. The IMPACTS relationship between the Vulnerability and the resource entity that was impacted serves as the record of the finding. The IMPACTS relationship carries properties such as 'identifiedOn', 'remediatedOn', 'remediationDueOn', 'issueLink', etc. |
Weakness |
A security weakness (e.g. CWE). |
Workload |
A virtual compute instance, it could be an aws-ec2-instance, a docker-container, an aws-lambda-function, an application-process, or a vmware-instance. The exact workload type is described in the _type property of the Entity. |
Special Entities
There are three special entities defined. These are singleton entities.
| Entity | Description |
|---|---|
Everyone |
The global UserGroup that represents "everyone" publicly. |
Internet |
The Internet - '0.0.0.0/0'. |
Root |
The entity that represents the top level organization. |
Relationships
A Relationship is the edge between two Entity nodes in the graph. The
_class of the relationship should be, in most cases, a generic descriptive
verb, such as HAS or IMPLEMENTS.
Relationships can also carry their own properties.
For example, CodeRepo -- DEPLOYED_TO -> Host may have version as a property
on the DEPLOYED_TO relationship. This represents the mapping between a code
repo to multiple deployment targets, while one deployment may be of a different
version of the code than another. Storing the version as a relationship
property allows us to void duplicate instances of the code repo entity to be
created to represent different versions.
Relationships have the same metadata properties as entities, which are managed by the integration providers.
