Method Detail

isAuthorized

public boolean isAuthorized(Object key,
                   Object runtimeParameter)

Description copied from interface: AccessController

isAuthorized executes the AccessControlRule that is identified by key and listed in the resources/ESAPI-AccessControlPolicy.xml file. It returns true if the AccessControlRule decides that the operation should be allowed. Otherwise, it returns false. Any exception thrown by the AccessControlRule must result in false. If key does not map to an AccessControlRule, then false is returned. Developers should call isAuthorized to control execution flow. For example, if you want to decide whether to display a UI widget in the browser using the same logic that you will use to enforce permissions on the server, then isAuthorized is the method that you want to use. Typically, assertAuthorized should be used to enforce permissions on the server.

Specified by:

isAuthorized in interface AccessController

Parameters:

key - key maps to <AccessControlPolicy><AccessControlRules> <AccessControlRule name="key"

runtimeParameter - runtimeParameter can contain anything that the AccessControlRule needs from the runtime system.

Returns:

Returns true if and only if the AccessControlRule specified by key exists and returned true. Otherwise returns false

assertAuthorized

public void assertAuthorized(Object key,
                    Object runtimeParameter)
                      throws AccessControlException

Description copied from interface: AccessController

assertAuthorized executes the AccessControlRule that is identified by key and listed in the resources/ESAPI-AccessControlPolicy.xml file. It does nothing if the AccessControlRule decides that the operation should be allowed. Otherwise, it throws an org.owasp.esapi.errors.AccessControlException. Any exception thrown by the AccessControlRule will also result in an AccesControlException. If key does not map to an AccessControlRule, then an AccessControlException is thrown. Developers should call assertAuthorized to enforce privileged access to the system. It should be used to answer the question: "Should execution continue." Ideally, the call to assertAuthorized should be integrated into the application framework so that it is called automatically.

Specified by:

assertAuthorized in interface AccessController

Parameters:

key - key maps to <AccessControlPolicy><AccessControlRules> <AccessControlRule name="key"

runtimeParameter - runtimeParameter can contain anything that the AccessControlRule needs from the runtime system.

Throws:

AccessControlException

assertAuthorizedForData

public void assertAuthorizedForData(String action,
                           Object data)
                             throws AccessControlException

Deprecated.

Description copied from interface: AccessController

Checks if the current user is authorized to access the referenced data. This method simply returns if access is authorized. It throws an AccessControlException if access is not authorized, or if the referenced data does not exist.

Specification: The implementation should do the following:

1. Check to see if the resource exists and if not, throw an AccessControlException
2. Use available information to make an access control decision
1. Ideally, this policy would be data driven
2. You can use the current User, roles, data type, data name, time of day, etc.
3. Access control decisions must deny by default
3. If access is not permitted, throw an AccessControlException with details

Specified by:

assertAuthorizedForData in interface AccessController

Parameters:

action -

data -

Throws:

AccessControlException

org.owasp.esapi.reference.accesscontrol.FileBasedACRs#assertAuthorizedForData(java.lang.String, java.lang.Object)

assertAuthorizedForFile

public void assertAuthorizedForFile(String filepath)
                             throws AccessControlException

Deprecated.

Description copied from interface: AccessController

Checks if the current user is authorized to access the referenced file. The implementation should validate and canonicalize the input to be sure the filepath is not malicious.

This method throws an AccessControlException if access is not authorized, or if the referenced File does not exist. If the User is authorized, this method simply returns.

Specification: The implementation should do the following:

1. Check to see if the File exists and if not, throw an AccessControlException
2. Use available information to make an access control decision
1. Ideally, this policy would be data driven
2. You can use the current User, roles, data type, data name, time of day, etc.
3. Access control decisions must deny by default
3. If access is not permitted, throw an AccessControlException with details

Specified by:

assertAuthorizedForFile in interface AccessController

Parameters:

filepath -

Throws:

AccessControlException

See Also:

org.owasp.esapi.reference.accesscontrol.FileBasedACRs#assertAuthorizedForFile(java.lang.String)

assertAuthorizedForFunction

public void assertAuthorizedForFunction(String functionName)
                                 throws AccessControlException

Deprecated.

Description copied from interface: AccessController

Checks if the current user is authorized to access the referenced function. The implementation should define the function "namespace" to be enforced. Choosing something simple like the class name of action classes or menu item names will make this implementation easier to use.

This method throws an AccessControlException if access is not authorized, or if the referenced function does not exist. If the User is authorized, this method simply returns.

Specification: The implementation should do the following:

1. Check to see if the function exists and if not, throw an AccessControlException
2. Use available information to make an access control decision
1. Ideally, this policy would be data driven
2. You can use the current User, roles, data type, data name, time of day, etc.
3. Access control decisions must deny by default
3. If access is not permitted, throw an AccessControlException with details

Specified by:

assertAuthorizedForFunction in interface AccessController

Parameters:

functionName -

Throws:

AccessControlException

                                throws AccessControlException

Deprecated.

Description copied from interface: AccessController

Checks if the current user is authorized to access the referenced service. This can be used in applications that provide access to a variety of backend services.

This method throws an AccessControlException if access is not authorized, or if the referenced service does not exist. If the User is authorized, this method simply returns.

Specification: The implementation should do the following:

1. Check to see if the service exists and if not, throw an AccessControlException
2. Use available information to make an access control decision

assertAuthorizedForURL

public void assertAuthorizedForURL(String url)
                            throws AccessControlException

Deprecated.

Description copied from interface: AccessController

Checks if the current user is authorized to access the referenced URL. The implementation should allow access to be granted to any part of the URL. Generally, this method should be invoked in the application's controller or a filter as follows:

ESAPI.accessController().assertAuthorizedForURL(request.getRequestURI().toString());

This method throws an AccessControlException if access is not authorized, or if the referenced URL does not exist. If the User is authorized, this method simply returns.

Specification: The implementation should do the following:
