When incorporating the ASP.NET DataGrid control into your Web apps, common operations such as paging, sorting, editing, and deleting data require more effort than you might like to expend. But all that is about to change. The GridView control--the successor to the DataGrid-- extends the DataGrid's functionality it in a number of ways. First, it fully supports data source components and can automatically handle data operations, such as paging, sorting, and editing, as long as its bound data source object supports these capabilities. In addition, ...

  • Security Briefs: A First Look at InfoCard
    The Web can be annoying at times. I'm certain that I'm not alone in my frustration with filling out the same old forms on every Web site I visit. Like most other techies, I've acquired many tools over the years to help combat this repetition, and I even wrote my own password manager for my hundreds of different identities on the Web.

    I've been spending a lot of time lately building secure Web services with the Microsoft® . NET Framework 2. 0, and Web Services Enhancements (WSE) 3. 0 has been a lifesaver for me, so I thought it would be appropriate to dedicate a column to security features in this new product.

  • Security Briefs: Access Control List Editing in .NET
    Access control lists (ACLs) can be complex beasts, and user interfaces for editing them are incredibly tricky to implement properly. That's why I was really excited when Windows® 2000 shipped with a programmable ACL editor, shown in Figure 1.

  • Security: Security Headaches? Take ASP.NET 2.0!
    ASP.NET 2.0 provides significant advantages with respect to security, especially for folks developing Web sites that use Forms authentication. By providing a user profile repository with support for roles, Forms authentication will move beyond the purview of the ASP.NET internals guru, and should become much more broadly accessible. This article introduces security in ASP.NET 2.0 to give you a head start with upcoming features.

  • Security Briefs: Beware of Fully Trusted Code
    The vast majority of managed applications run with full trust, but based on my experience teaching . NET security to developers with a broad range of experience, most really don't understand the implications of fully trusted code.

  • Authorize It: Use Role-Based Security in Your Middle Tier .NET Apps with Authorization Manager
    Authorization Manager in Windows Server 2003 represents a significant improvement in the administration of role-based security, making it more scalable, flexible, and easier to implement. Using Authorization Manager, you can define roles and the tasks those roles can perform. You can nest roles to inherit characteristics from other roles, and you can define application groups. In addition, Authorization Manager lets you use scripts to modify permissions dynamically, and it allows you to wrap your security logic in a security policy that can be stored in Active Directory. Authorization Manager also includes an easy-to-use API for running access checks. The author discusses all of these topics and demonstrates them with a working sample.

  • Security Briefs: Exploring S4U Kerberos Extensions in Windows Server 2003
    Building Web sites that provide services external to the corporate firewall is tricky. Usually it's not desirable to grant corporate domain accounts to external clients, and from a purely practical standpoint Kerberos does not work well over the Internet due to the typical configuration of client-side firewalls.

  • Security Tips: Defend Your Code with Top Ten Security Tips Every Developer Must Know
    There are many ways to get into trouble when it comes to security. You can trust all code that runs on your network, give any user access to important files, and never bother to check that code on your machine has not changed. You can run without virus protection software, not build security into your own code, and give too many privileges to too many accounts. You can even use a number of built-in functions carelessly enough to allow break-ins, and you can leave server ports open and unmonitored. Obviously, the list continues to grow. What are some of the really important issues, the biggest mistakes you should watch out for right now so that you don't compromise your data or your system? Security experts Michael Howard and Keith Brown present 10 tips to keep you out of hot water.

  • HTTP Pipelines: Securely Implement Request Processing, Filtering, and Content Redirection with HTTP Pipelines in ASP.NET
    ASP.NET is a flexible and extensible framework for server-side HTTP programming. While most people think of ASP.NET in terms of pages served, there is a lower-level infrastructure sitting beneath this page model. The underlying plumbing is based on a pipeline of app, module, and handler objects. Understanding how this pipeline works is key if you want to get the most out of ASP.NET as an HTTP server platform, while making your process more efficient, and keeping your server secure. This article introduces the architecture of the pipeline and shows how you can use it to add sophisticated functionality to an ASP.NET-based app.

  • Security in .NET: Enforce Code Access Rights with the Common Language Runtime
    Component-based software is vulnerable to attack. Large numbers of DLLs that are not tightly controlled are at the heart of the problem. Code access security in the Common Language Runtime of the Microsoft .NET Framework addresses this common security hole. In this model, the CLR acts as the traffic cop to assemblies, keeping track of where they came from and what security restraints should be placed on them. Another way the .NET Framework addresses security is by providing preexisting classes which have built-in security. These are the classes that are invoked in .NET when performing risky operations such as reading and writing files, displaying dialog boxes, and so on. Of course, if a component calls unmanaged code, it can bypass code access security measures. This article covers these and other security issues.

  • Web Security: Part 2: Introducing the Web Application Manager, Client Authentication Options, and Process Isolation
    This article, the second of two parts, continues coverage of Web security for Windows. It introduces the Web Application Manager in IIS that allows Web processes to be isolated, decreasing the security risk associated with running in a logon session. The article then picks up where Part One left off-it discusses authentication methods such as basic authentication, digest authentication, integrated Windows authentication, and anonymous logons, and the benefits and drawbacks of each.

  • Web Security: Putting a Secure Front End on Your COM+ Distributed Applications
    The Internet requires that developers provide a different security model for clients than is used on a closed network. Because it would be too resource-intensive for both the client and server to prove their identity to each other, you need to look at other ways to ensure secure communications. This article covers the options, from digital certificates to public and private key encryption to Secure Sockets Layer and Web certificates. The discussion covers the installation of certificates in Microsoft Internet Information Services along with other options specific to IIS. This article was adapted from Keith Brown's Programming Windows Security (Addison-Wesley), due out in July 2000.
