RootCA
Representation
The RootCA node represents the Active Directory LDAP objects of the certificationAuthority class located in the Certification Authorities container in the Configuration Naming Context.
Node properties
The node supports the properties of the table. Three types of property names will be used, depending on where the property is found:
- Entity Panel: Name shown in the BloodHound UI.
- Database: Name stored in the BloodHound database and returned by the BloodHound API. This is to be used when running Cypher queries.
- Directory: Name collected from the directory the node is stored in, for example, the LDAP name for an Active Directory property.
| Entity Panel | Database | Directory | Description |
| Object ID | objectid | objectGUID | The object’s unique identifier in the directory. |
| ACL Inheritance Denied | isaclprotected | nTSecurityDescriptor | Whether inherited permissions (ACEs) from containers are blocked on this object. |
| Basic Constraint Path Length | basicconstraintpathlength | caCertificate (X509Certificate) | The maximum number of non-self-issued intermediate certificates that may follow this certificate in a valid certificate chain. |
| Certificate Chain | certchain | caCertificate (X509Certificate) | A hierarchical list of certificates starting with the certificate for this CA and ending with a self-signed root certificate. Each certificate is signed by the private key of the next CA certificate. |
| Certificate Name | certname | caCertificate (X509Certificate) | The name of the CA’s certificate. |
| Certificate Thumbprint | certthumbprint | caCertificate (X509Certificate) | The thumbprint (unique identifier) of the CA’s certificate. |
| Created | whencreated | whenCreated | When the object was created in the directory. |
| Distinguished Name | distinguishedname | distinguishedName | The name of the object and it’s location in AD. |
| Domain FQDN | domain | - | The fully qualified domain name (FQDN) of the domain the object belongs to. |
| Domain SID | domainsid | - | The SID of the domain the object belongs to. |
| Has Basic Constraints | hasbasicconstraints | caCertificate (X509Certificate) | Whether the CA certificate has basic constraints. |
| Last Collected by BloodHound | lastcollected | - | The most recent time the object was collected and ingested in BloodHound. |
| Last Seen by BloodHound | lastseen | - | The most recent time the object or a reference to it was collected and ingested in BloodHound. |
| - | name | name + domain name | Name of the object + @ + the name of the domain. |
