Wren:ICF

Overview

Wren:ICF is an umbrella brand encompassing community-developed Identity Connector Framework as well as a set of production-ready connectors – LDAP, Office 365, SSH, SQL, PowerShell, REST and many more.

The main project is Wren:ICF Java Framework where the various parts of the framework (specification, APIs, SPIs and network protocol) are forged, and it also provides the default connector runtime environment for the Java world.

Wren:ICF .NET Framework is a connector framework implementation and runtime environment for Microsoft's .NET world.

Framework Features

Wren:ICF addresses the following topics:

• connector specification – definition of connector interfaces and available operations
• connector runtime environment – Java and .NET server implementations managing individual connectors, their discoverability and lifecycle (e.g. pooling)
• remote connector protocol – low-level remote connector network protocol

Runtime environment manages individual connectors through connector SPI methods and offers their functionality through public API. Each connector works with a specific set of objects (e.g. accounts and groups) defined by self-described schema, and can implement one or more well defined operations.

Identity Connectors

Wren:ICF provides a set of common basic connectors and scriptable connectors with sample integrations:

• LDAP Connector – integration with LDAP server (e.g. Active Directory)
• CSV File Connector – reading and writing rows from a CSV file
• Scriptable SSH Connector – custom remote shell invocations through managed JSch connection
• Scriptable SQL Connector – custom database commands through managed JDBC connection
• Scriptable REST Connector – custom calls through managed HTTP connection
• Scriptable Groovy Connector – custom groovy scripts for Wren:ICF operations
• Scriptable PowerShell Connector – custom PowerShell scripts for Wren:ICF operations

Many other connectors are available under Wren Security's GitHub organization or by third-party vendors.
