Abstract

Example embodiments provide for a rule-based wizard type tool for generating secure policy documents. Wizard pages present a user with general Web Service security options or questions at a user interface, which abstracts the user from any specific code, e.g., XML code, used for creating a Web Service policy document. Based on user input selecting general criteria, security rules are accessed and evaluated for automatically making choices on behalf of the user for creating a secure policy document. Other embodiments also provide for presenting the user with an easily understandable visual representation of selected criteria of a policy document in, e.g., a tree like structure that shows relationships between various elements of the criteria.

Claims

1. At a computer system in a Web Services environment, a method of assisting a user in generating a more secure policy document by providing a rule-based tool that automatically selects security conditions for the user'"'"'s general security criteria such that the user does not have exposure to all security details, the method comprising acts of:

at a generation phase of the secure policy document;

presenting a set of Web Service security options to the user at a user interface, which abstracts the user from any specific code that will be generated for a secure policy document that satisfies one or more of the set of Web Service security options;

receiving user input selecting a general security criteria from the set of Web Service security options presented;

based on the received user input, accessing one or more security rules from a repository of extensible security metadata, the one or more security rules corresponding to the general security criteria;

determining whether the secure policy document to be generated is a client policy document or a service policy document; and

using the one or more security rules corresponding to the general security criteria to generate the secure policy document in accordance with the general security criteria, wherein generating the secure policy document includes automatically selecting specific security conditions that enforce the general security criteria input by the user, and wherein the security conditions that are more specific than the general security criteria input by the user are automatically selected based at least in part on whether the secure policy document is determined to be a client policy document or a service policy document, such that different one or more security rules are selected and applied in creating the secure policy document when the secure policy document is a client policy document as compared to when the secure policy document is a service policy document.

2. The method of claim 1, wherein the one or more security rules are based on Web Service industry wisdom from input given by experts in the industry for security purposes.

13. The method of claim 12, wherein the one or more security rules are based on Web Service industry wisdom from input given by experts in the industry for security purposes.

14. The method of claim 12, wherein the one or more security rules are based on governmental policies and the one or more security rules assist the user in creating a governmental conformant secure policy document.

15. The method of claim 14, wherein the one or more security rules are further based on Web Service'"'"'s policies and the one or more security rules assist the user in creating a secure policy document that conforms to the Web Service'"'"'s policies.

16. The method of claim 12, wherein the one or more security rules are used to generate a next set of options based on the received user input.

17. The method of claim 16, wherein the one or more security rules are used to not present a user with a specific option in order to prevent the user from selecting an invalid option.
