OACC - pronounced [oak] - is a fully featured API to both enforce and manage your application's authentication and authorization needs.

In a nutshell, OACC provides permission-based authorization services and allows your application to enforce security by answering the question:

Is entity 'A' allowed to perform action 'p' on entity 'B'?

• Fully implemented API
  All the functionality to manage your application's security model, out of the box.

• Single access-control paradigm
  Always operate at the resource level. Manage permissions exclusively between resources.

• Flexible security model
  Secure any operation between your domain objects and the actors on them.

• Permission delegation
  Authorize subjects to delegate their permissions to others with GRANT OPTIONS.

• Identity delegation
  Authorize an authenticated subject to securely "impersonate" another subject.

• Efficient query methods
  Find resources by permission with efficient symmetric query methods.

Learn more about all of OACC's authorization and authentication features on the Features page of the project website.

The easiest way to include the latest OACC release into your project is to declare the following Maven coordinates as a dependency in your POM file:

<dependency>
    <groupId>com.acciente.oacc</groupId>
    <artifactId>acciente-oacc</artifactId>
    <version>2.0.0</version>
</dependency>

To install, configure and initialize the OACC database, please refer to the Get Started Tutorial on the project website.

The SecureTodo sample application illustrates how to integrate OACC into a Java application and how to address several real-world authorization scenarios. The writeup is also available in the Github repository that contains the full source code.
