Permission Schemes

A permission scheme is a set of

assignments for the project permissions

Every project has a permission scheme

One permission scheme can be associated with multiple projects

Permission schemes prevent having to set up permissions individually for every project

UserService uses UserDAO and FacebookWS

And you shouldn’t really care, all that is important is that UserService depends on dao and webservice object.

Joshua Blooch gives fine example of builder pattern.

Instead of making the desired object directly, the client calls a constructor (or static factory) with all of the required parameters and gets a builder object. Then the client calls setter-like methods on the builder object to set each optional parameter of interest. Finally, the client calls a parameterless build method to generate the object, which is immutable. The builder is a static member class of the class it builds.

Principle of least privilege

object-capability model, any software entity can potentially act as both a subject and object

Access control models used by current systems tend to fall into one of two classes:

Both capability-based and ACL-based models have mechanisms to allow access rights to be granted to all members of a group of subjects (often the group is itself modeled as a subject)

identification and authentication determine who can log on to a system, and the association of users with the software subjects that they are able to control as a result of logging in; authorization determines what a subject can do; accountability identifies what a subject (or all subjects associated with a user) did.

Authorization determines what a subject can do on the system

Authorization

Access control models

categorized as either discretionary or non-discretionary

three most widely recognized models are

Attribute-based access control

Discretionary access control

Discretionary access control (DAC) is a policy determined by the owner of an object. The owner decides who is allowed to access the object and what privileges they have.

Every object in the system has an owner

access policy for an object is determined by its owner

DAC systems, each object's initial owner is the subject that caused it to be created

Mandatory access control

Mandatory access control refers to allowing access to a resource

that allow a given user to access the resource

Management is often simplified (over what can be required) if the information can be protected using

or by implementing sensitivity labels.

Sensitivity labels

A subject's sensitivity label specifies its

level of trust required for access

subject must have a sensitivity level equal to or higher than the requested object

Role-based access control

Role-based access control (RBAC) is an

access policy

Object-Level Security

Caching: Spring Security optionally integrates with Spring's Ehcache factory. This flexibility means your database (or other authentication repository) is not repeatedly queried for authentication information when using Spring Security with stateless applications.

Run-as replacement: The system fully supports temporarily replacing the authenticated principal for the duration of the web request or bean invocation. This enables you to build public-facing object tiers with different security configurations than your backend objects.

Tag library support: Your JSP files can use our taglib to ensure that protected content like links and messages are only displayed to users holding the appropriate granted authorities. The taglib also fully integrates with Spring Security's ACL services, and obtaining extra information about the logged-in principal.

User Provisioning APIs: Support for groups, hierarchical roles and a User management API, which all combine to reduce development time and significantly improve system administration.

it's so contrary to the basic idea of object-oriented design

procedural style design

completely miss the point of what object-oriented design is all about

It's also worth emphasizing that putting behavior into the domain objects

One source of confusion in all this is that many OO experts do recommend putting a layer of procedural services on top of a domain model, to form a Service Layer

this isn't an argument to make the domain model

service layer advocates use a service layer in conjunction with a behaviorally rich domain model.
