Abstract: In one set of embodiments, methods, systems, and apparatus are provided to attach one or more service policies to resources in an enterprise by receiving a first service policy, receiving a first policy attachment that identifies one or more policy attachment attributes of resources in the enterprise, and generate a first global policy attachment that references the first policy attachment and the first service policy. The method can include receiving a request to access a resource including an attribute that matches one of the policy attachment attributes. The method can include determining that the first service policy is an effective policy for the resource based on the matching resource attribute with the policy attachment attribute. The method can include controlling access to the resource responsive to the request using the effective policy.

Abstract: In one set of embodiments, methods, systems, and apparatus are provided to attach one or more quality of service policies to resources in an enterprise system by receiving a first global policy attachment that references an attachment attribute value and a first service policy, receiving a request to access a policy subject associated with a subject attribute value, identifying an effective policy set referenced by the first global policy attachment, the effective policy set including the first service policy if the attachment attribute value equals the subject attribute value, and granting the request to access based upon the at least one effective policy. The at least one effective policy may further include a first service policy referenced by the first global policy attachment if a first policy attachment scope referenced by the first global policy attachment matches or contains a subject scope associated with the policy subject.

Abstract: Framework for conditionally attaching web service policies to a policy subject (e.g., a web service client or service endpoint) at subject runtime. In one set of embodiments, a validation process can be performed at a policy subject during an initialization phase to ensure that there are no validation errors with respect to the web service policies that may be conditionally attached to the subject. This validation process can include grouping the policies that have been associated with the policy subject (via policy attachment metadata) by their corresponding constraint expressions, and determining which groups can potentially overlap (i.e., be simultaneously attached to the policy subject) at runtime. Each set of overlapping groups can then be validated using a predefined set of validation rules to identify potential errors pertaining to the policies in the set.

Abstract: Techniques for resolving conflicts between web service policies that are attached (via LPA and/or GPA metadata) to a policy subject (e.g., a WS client/service endpoint). In one set of embodiments, a priority value can be assigned to each policy attached to a policy subject via the policy's corresponding policy attachment metadata file. These priority values can be taken into account when determining whether one policy should be given precedence over another, conflicting policy attached to the same policy subject. In certain embodiments, as part of this determination, the priority value of a policy can be given greater weight than the scope at which the policy is attached.

Abstract: Framework for conditionally attaching web service policies to a policy subject (e.g., a web service client or service endpoint) at subject runtime. In one set of embodiments, a constraint expression can be defined that specifies one or more runtime conditions under which a policy should be attached to a policy subject. The constraint expression can be associated with the policy and the policy subject via policy attachment metadata. The constraint expression can then be evaluated at runtime of the policy subject to determine whether attachment of the policy to the policy subject should occur. If the evaluation indicates that the policy should be attached, the attached policy can be processed at the policy subject (e.g., enforced or advertised) as appropriate. Using these techniques, the policy subject can be configured to dynamically exhibit different behaviors based on its runtime context.

Abstract: Techniques for resolving conflicts between web service policies that are attached (via LPA and/or GPA metadata) to a single policy subject (e.g., a WS client/service endpoint). In one set of embodiments, a determination can be made whether two conflicting policies that are attached to a single policy subject are identical. This determination can be based on, e.g., a Uniform Resource Identifier (URI) that is used to identify the policies in their respective policy attachment metadata files, as well as any policy configuration properties. If the two conflicting policies are determined to be identical, the policy attachment metadata for one of the policies can be considered valid, while the policy attachment metadata for the other, duplicate policy can be ignored. In this manner, validation errors arising from duplicate policy attachments can be avoided.
