Revision as of 06:51, 16 June 2011

This document is currently under development - Please use the Discussion page for threaded conversation

Proposed Migration Roadmap

  • ESAPI 2.1
    • Create new package org.owasp.esapi.core
    • Create new set of Interfaces in new package with each extending it's org.owasp.esapi counterpart
    • Deprecate methods in org.owasp.esapi Interfaces
  • ESAPI 2.5
    • Remove deprecated methods that were deprecated at or before ESAPI 2.0
    • Introduce new ServiceLocator API
  • ESAPI 3.0
    • Seperate Core API into it's own artifact/project called ESAPI-Core
    • Create new set of artifacts as outlined in ESAPI_Project_Structure
    • Introduce Core API Testing Suite

Core API Specification

AccessController

The AccessController is responsible for determining if the currently logged in user has access to a given resource. The resource can be anything that implements the Resource Interface.

Changes from ESAPI 2.0

  • Removed deprecated methods
  • Added Generic Stereotypes to the Key and Context parameters)

StereoTypes

Parameter Description
R A class that implements the Resource Interface and represents the Resource the user is requesting access to
Context Any object that represents the current context of the Authorization request - this is generally a Key-Value map

Methods

<R extends Resource,Context> void assertAuthorized(Resource resource, Context context) throws AccessDeniedException

Assert that the currently logged in user can access the given Resource with the given Context parameters

Parameters
Parameter Default Value Description
resource The resource that the user is attempting to access
context The context of the request. This could be any type of object - for instance if requesting access to data, the context may be the resource identifier for the identified resource.
Exceptions
Exception Description
AccessDeniedException If the assertion evaluates to false, an AccessControlException will be thrown with contextual information as to the reason for the failure

<R extends Resource,Context> boolean isAuthorized(Resource resource, Context context)

Determine if the given resource is accessible by the currently logged in User

Parameters
Parameter Default Value Description
resource The resource that the user is attempting to access
context The context of the request. This could be any type of object - for instance if requesting access to data, the context may be the resource identifier for the identified resource.
Return

Returns true if the resource is accessible to the currently logged in user and false if it is not.
