Table 2: Ports required for communication
Port Direction Description

8721

Incoming

TCP (HTTP) port opened on the Data Governance server computer. This is the base port for the Data Governance REST API, used for communication with Data Governance server REST services, including the One Identity Manager clients and Windows PowerShell.

8722

Incoming

TCP (net.tcp) port opened on the Data Governance server computer. Used for communication with Data Governance agents, One Identity Manager clients, One Identity Manager web server, and PowerShell.

NOTE: The net.tcp port is configurable in the Data Governance Configuration wizard. The HTTP port (8721) listed above should always be 1 less than the net.tcp port. These first two ports align with the base addresses in the DataGovernanceEdition.Service.exe.config file under the IndexServerHost service. It is highly recommended that you only change this port using the Data Governance Configuration wizard to ensure the configuration file, One Identity Manager database and service connection points are updated properly; otherwise, you may lose connection with the Manager, the Data Governance service and/or Data Governance agents.

IMPORTANT: Do NOT use the Designer to change the QAMServer configuration parameters, including the Port parameter.

8723

Incoming

HTTP port used for communication with the One Identity Manager web server (/landing and /home pages).

18530 - 18630

Incoming

TCP port range opened on all agent computers. Used for communication with the Data Governance server. (The first agent on an agent host will use port 18530, and each subsequent agent on the same host will take the next available port, i.e., 18531, 18532, and so on.). In addition, this range is used to open a TCP listener for NetApp Cluster Mode hosts if resource activity collection is enabled.

Component communication

Server and database communication

Information about all Data Governance Edition infrastructural elements such as service accounts, managed hosts and the security index information collected by the Data Governance agents is stored in the One Identity Manager database. Processing of security index updates, access and activity queries or any infrastructural changes to the system involve communication between the Data Governance server and the database.

How is the database connection information stored securely?

The connection information used when communicating with the One Identity Manager database is stored in the Windows Registry on the Data Governance server. The connection information is written to the registry key "HKLM\SOFTWARE\One Identity\Broadway\Server" and is encrypted using the Microsoft Data Protection API.

Only the user account that encrypts the value can read it. If the account running the Data Governance server is changed, the database connection string has to be reset and re-encrypted.

Agent and server communication

Data Governance agents are semi-autonomous services running in a distributed environment. They are designed to remain fault tolerant in a fluctuating global network. In a typical organization, computers are rebooted, network outages occur, and systems are disrupted in any number of ways. Data Governance agents are set to automatically start when a server is restarted. Data Governance agents require an initial configuration from the server; however, they will continue to scan and collect activity per configuration even when unable to communicate with the Data Governance server. All the collected activity and security updates are synchronized with the Data Governance server when connectivity is restored.

How is this communication encrypted?

The communication uses encrypted WCF (Windows Communication Foundation) channels and the net.tcp protocol. .NET v4.5 is required on all agent host computers, except for SharePoint 2010 agents, which requires .NET v3.5.1.

Client and server communication

Data Governance client elements are embedded into the Manager client application. The user interface elements communicate with the Data Governance server and directly with the One Identity Manager database as needed.

Communication with the database is performed in the same way as any other One Identity Manager database communication, using the authentication information provided when the user launches the client tools.

When communicating with the Data Governance server, the client uses an encrypted WCF channel and the net.tcp protocol.

.NET 4.5.2 is required on the Data Governance server and client computers.

How is this communication authenticated?

When communicating directly with the One Identity Manager database, the client is authenticated using standard One Identity Manager authorization checks. For more information on this type of authentication, see Granting Access Permissions to One Identity Manager Schema in the One Identity Manager Configuration Guide.

When user interface elements communicate with the Data Governance server, the authentication is performed using the One Identity Manager role-based authentication checks using the logged on Windows identity. This can lead to a discrepancy in authentication between the client and server. If possible, it is recommended that the client user authenticates to One Identity Manager using the “Active Directory user account (role based)” authentication mechanism, so no ambiguity exists. This mechanism maps the logged on Active Directory account to a One Identity Manager employee and uses that employee’s application roles to determine what permissions they have.

NOTE: Regardless of the identity used to log in to the client application, it is the Employee associated with the logged in Windows account that is used for permissions checks when communicating with the Data Governance server.
