Good tips and hints.In order to solve web application vulnerabilities we have created HDIV (HTTP Data Integrity Validator) open source project. We can briefly define HDIV as a Java Web Application Security Framework. HDIV extends web applications’ behaviour by adding Security functionalities, maintaining the API and the framework specification. This implies that we can use HDIV in applications developed in Struts 1.x, Struts 2.x, Spring MVC and JSTL in a transparent way to the programmer and without adding any complexity to the application development. It is possible to use HDIV in applications that don’t use Struts 1.x, Struts 2.x, Spring MVC or JSTL, but in this case it is necessary to modify the application (JSP pages). The security functionalities added to the web applications are these: INTEGRITY: HDIV guarantees integrity (no data modification) of all the data generated by the server which should not be modified by the client (links, hidden fields, combo values, radio buttons, destiny pages, etc.). Thanks to this property HDIV helps to eliminate most of the vulnerabilities based on the parameter tampering. EDITABLE DATA VALIDATION: HDIV eliminates to a large extent the risk originated by attacks of type Cross-site scripting (XSS) and SQL Injection using generic validations of the editable data (text and textarea). CONFIDENTIALITY: HDIV guarantees the confidentiality of the non editable data as well. Usually lots of the data sent to the client has key information for the attackers such as database registry identifiers, column or table names, web directories, etc. All these values are hidden by HDIV to avoid a malicious use of them. For example a link of this type, http://www.host.com?data1=12&amp;data2=24 is replaced by http://www.host.com?data1=0&amp;data2=1, guaranteeing confidentiality of the values representing database identifiers. Also it is possible to hide the name of the parameters becoming the link into http://www.host.com?0=0&amp;1=1. ANTI-CROSS SITE REQUEST FORGERY (CSRF) TOKEN: Random string called a token is placed in each form and link of the HTML response, ensuring that this value will be submitted with the next request. This random string provides protection because not only does the compromised site need to know the URL of the target site and a valid request format for the target site, it also must know the random string which changes for each visited page.http://www.hdiv.org/gresch2008-09-02T15:28:10+02:00software http integrity data security develop springframework In order to solve web application vulnerabilities we have created HDIV (HTTP Data Integrity Validator) open source project.

Used in conjunction with Spring autowiring of bean dependencies you can develop teired application contexts that represent the architectural tiers of your application, and thus you testing strategy. The simplest example is a separation of service beans and DAO beans into separate xml application contexts so that the services can be fully tested in isolation of the DAOs. The DAO beans are still required by the services typically as an injected property. Spring AutoMock can automatically register a Mock and a proxy of certain beans, so that the Mocks can be injected into your test cases and the matching proxy into the item under test. This reduces the need for repeated Spring test configuration.http://automock.sourceforge.net/gresch2008-09-02T15:23:58+02:00software mock testing java develop qa springframework Spring AutoMock is a test enabling framework to allow automatic exposure of Mocked beans for a Spring application.

It allow complex processes to be layed out and managed graphically which promotes rapid development and ease of maintenance. Physhun is lightweight enough to run in simple standalone applications, but flexible and powerful enough to be used for orchestration in SOA. Physhun allows processes to be long lived, persistent and transactional. Processes can be purely synchronous, or can be interacted with asynchronously as is common in Workflow processes. The Physhun framework uses the Spring framework, and exposes all of the value added services provided by Spring, including inversion of control (IOC), aspect-oriented programming (AOP) and transaction management. Process control with Physhun is accomplished by defining processes as state models. A state model is defined as a Spring bean, comprised of States, Transitions, Conditions and Actions, all of which are also defined as Spring beans. Actions contain the implementation of the behavior that is executed on state transitions. Similarly, conditions contain the implementation that codifies the conditions that must be met for a state transition to occur. Predefined Actions and Conditions are provided in the Physhun framework and the Physhun-XML packages, or the user can easily define custom Actions and Conditions as necessary. Furthermore, the framework is built in such a way that things like state machine rules, process storage, caching and lookup, etc can be customized and plugged in. State models can be defined programatically, by writing XML defining the state model, or graphically using an editor like freely available Physhun Modeler. Physun Modeler is a free GUI that can be used to graphically define state models. PhyshunModeler software is provided free of charge, but is not open source software.http://physhun.sourceforge.net/gresch2008-08-28T15:29:32+02:00software frameworks java_ee develop statechart soa springframework finite Physhun is a framework for modeling, building and executing processes as Finite State Models in J2SE and J2EE environments.

JaValid is licensed under the Eclipse Public License 1.0. JaValid 1.1-rc1 is the latest release. JaValid is an annotation-based validation framework, which allows you to annotate your Java objects to introduce validation. JaValid can be used in any type of Java application (standalone application, web application etc). The framework currently provides full integration with the Spring Framework, Java Server Faces, Facelets, and any database. The framework can be extended easily, by means of extensions, and allows you to add your own validation constraints in addition to the ones shipping with the framework. The framework is documented well (both the source and the general documentation), so check it out. To learn more, have a look on the documentation page. The source and distributions are hosted on sourceforge, go to the downloads directly here. You may also want to check out the weblog, which contains some useful information, including several examples.
