Description

Soffid Console provides a graphical interface, with a hierarchy structure, that allows the management of Policy Decision Points in a easy way. You can create new policy sets, policies, policy set references and policy references.

To start you only need to click the button with the add symbol (+) and start to configure the policy set.

Once you have created the root policy set, you can add new policy sets, polices, policy set references and policy references as your company need. You only need to click on the proper button and fulfill the data. You can add more than one root policy set.

Also, you can import a PolicySet into the system. You need click the import option on the hamburger icon and pick up the file to import, that file must be a well-formed XML.

Policy set

Description

A PolicySet is a container that can hold other Policies or PolicySets, as well as references to policies found in remote locations.

Every PolicySet contains a target and obligations, both can be empty.

The target contains the subjects, resources, actions and environments where the policy set will be applied. A target can contain more than one subject, environment, resource or action or none of them. And contains 

Policy Set can be exported to an XML file by clicking on Export button. The file will contain the Policy Set Target and all the elements included in it, like other PolicySets, Policies or References.

It is possible to create a new version for a PolicySet by clicking on 'Add new version'. That will copy all PolicySet elements on the tree with the following version number.

Target

Description

In XACML all the attributes are categorized into four main categories:

• Subjects
• Resources
• Actions 
• Environments

A target can contains more than one subject, environment, resource or action or none of them. The target is the way to define the scope of an autorization policy. The result will be MATCHES if it all the target elements defined match.

• Attribute Designator: lets the policy specify an attribute with a given name and type, and optionally an issuer as well.
• Attribute Value: contains a literal attribute value.

Categories

Subjects

An actor whose attributes may be referenced by a predicate.

Allows you to add one or more subjects as a target where the policy will be applied.

To configure a subject, first of all you need to select an attribute. You can select a value for an attribute designator list, or write the attribute selector value and select the data type.

Then, you need to select the operator, it will be used to compare or compute attributes.

And finally, you need to set a value, with which the attribute will be computed or compared. The value data type depends on the attribute data type.

Resources

Data, service or system component.

Allows you to add one or more resources as a target where the policy will be applied.

To configure a resource, first of all you need to select an attribute. You can select a value for a attribute designator list, or write the attribute selector value  and select the data type.

Then, you need to select the operator, it will be used to compare or compute attributes.

And finally, you need to set a value, with which the attribute will be computed or compared. The value data type depends on the attribute data type.

Actions

An operation on a resource.

Allows you to add one or more actionss as a target where the policy will be applied.

To configure an action, first of all you need to select an attribute. You can select a value for a attribute designator list, or write the attribute selector value  and select the data type.

Then, you need to select the operator, it will be used to compare or compute attributes.

And finally, you need to set a value, with which the attribute will be computed or compared. The value data type depends on the attribute data type.

Environments

The set of attributes that are relevant to an authorization decision and are independent of a particular subject, resource or action.

Allows you to add one or more environments as a target where the policy will be applied.

To configure an environment, first of all you need to select an attribute. You can select a value for a attribute designator list, or write the attribute selector value  and select the data type. The 

Then, you need to select the operator, it will be used to compare or compute attributes.

And finally, you need to set a value, with which the attribute will be computed or compared. The value data type depends on the  attribute data type.

Actions

The behavior of the actions is the same in each category, subjects, actions, resources and environments. 

Add new	Allows you to add a new element to the list. To add a new element you need to click the add button, located at the end of the header and fulfill the form and save the data.

Rules

Description

A rule is the most elementary unit of policy. It may exist in isolation only within one of the major actors of the XACML domain. In order to exchange rules between major actors, they must be encapsulated in a policy. A rule can be evaluated on the basis of its contents.

A rule is composed by a target, an effect and a condition. It is able to add more than one rule to the policy.

Obligations

Description

XACML defines obligations as actions that have to be returned to the PEP with the PDP response XACML .

If the PDP's evaluation is viewed as a tree of rules, policy sets and policies, each of which returns "Permit" or "Deny", then the set of obligations returned by the PDP to the PEP will include only the obligations associated with those paths where the effect at each level of evaluation is the same as the effect being returned by the PDP.
