Implementing fine-grain security policies in enterprise HTML5 applications
What is fine-grain security?
Fine-grained access control refers to the data security model where users of different permissions are given different sets of access rights to read, right, or edit data. Considering fine-grained security policy within applications is becoming more important as apps are increasingly designed to reach a wider group of users. As businesses move to bring their apps to web and mobile, it is more common to create different views of the same core application that are optimized for the specific audience. For instance, an application admin will have a different view than a user performing data entry in the field and a different view from the manager looking for summary statistics. These different application "views" all carry different access rights to the data. Implementing fine-grained security policies within an application is typically the role of the application administrator. Designing in utilities to manage fine-grained access control is the role of the developer.

Leveraging Visual WebGui to integrate fine-grain security into your apps
Gizmox recently announced new features of Visual WebGui that supports the ability to define form-level security policies within VWG apps. Visual WebGui is designed to integrate with enterprise access control technologies like LDAP or Active Directory where access rights can be managed centrally. Visual WebGui developers can build fine-grained policy control that lets application admins define the specific access rights of different types of usersat runtime. The Visual WebGui Business Server integrates with enterprise access control servers at runtime to enforce policy within the application. Abstracting this functionality to the platform level radically simplifies the process of building this kind of access control into an application..Demo

Security enhancement feature added to Visual WebGui enterprise HTML5 Platform
Access to an enterprises internal web based application poses significant security problems for most organizations. With the expansion of the internet and BYOD, applications that were accessed in the past only from within an organization over an internal intranet network have now expanded to the outside world in the form of mobiles and tablets found at employee’s homes or on the road. As these applications usually contain sensitive data, a developer must consider a whole world of scenarios that need to take effect specifically, the systems firewall which protects from hacking and the authentication and authorization mechanism. Internal enterprise applications usually require authentication and authorization by a logged in user to access certain or all of the information on a given application. Moreover, these applications need to make decisions based on a given logged in user: some pages or actions might be restricted to only logged in users, or to a certain subset of users; other pages might show information specific to the logged in user, or might show more or less information, depending on the user viewing the page.

Creating a forms security
At Gizmox, we have always focused on how to ease the developers’ transition to secure, native-like, HTML5 web application development so that it as friendly and familiar as possible. For this reason. we have created the Forms Security mechanism in Visual WebGui. This mechanism allows developers to fairly easily and rapidly integrate a filesystem-based permissions mechanism into Visual WebGui applications which run in an Active Directory environment on Windows operating systems. This is done by generating a dummy file for each form in an application, in a dedicated directory under the application root. After this has been generated, a system admin for example, could leverage access to the application’s forms by modifying the appropriate dummy file permissions through a familiar IIS Manager or file system interface..Building secure internal web based applications for enterprises will surely come naturally for Visual WebGui developers, making the look and feel of your Visual WebGui’s application as native to the device as possible with native level security

USING VISUAL WEBGUI VISUAL EFFECTS TO BUILD INTERACTIVE APPLICATION UI'S
Desktop vs. Web Application Interface Design
Building effective user interfaces for enterprise applications is one of the most confounding elements of business application programming. Genius developers that excel at linking complex data sources, designing highly efficient application logic, and architecting well organized user screen stacks often struggle to build attractive, intuitive, and responsive UIs. The challenge is that building good UIs requires equal parts art, social science, and programming skill. This challenge is felt particularly strongly in the world of business application development. As business app developers are shifting away from desktop application platforms to web development for delivery on both desktops and mobile devices. Desktop development tools like VB6 and PowerBuilder had well developed UI tools based on windows based user interaction models. Adapting user interface concepts to desktop and mobile web poses unique challenges to developers. This MSDN article “Designing for Web or Desktop?” provides a nice comparative summary of the topic.Visit our blog for our entire selection of blogs
While there are a rich sets of HTML5 controls that the C# or Java programmer can use to help with web design, many of of the web development toolsets were conceived to facilitate development of modern websites – not to support the specific interaction model of business applications. In preparing this article, I found this older article from Smashing Magazine discussing the specific differences in designing website UIs vs. web application UI interesting.
Customizing Properties of Application Controls
One of the challenges facing the web application developer who is making the transition from desktop development is that they do not have the direct access to control properties they do with desktop development environments. Gizmox Visual WebGui is a web application development environment built with the desktop developer in mind. Part of this is giving the same kind of access to the appearance and behavior of the application control set that desktop developers get. The video series below provides an overview of how to modify the visual effects of Visual WebGui controls. For an extensive set of examples including sample code, check out the Visual WebGui CompanionKit section dedicated to Visual Effects.Using Visual WebGui Visual Effects
