INFO: .NET Framework Change in Default Machine Level Security Policy (Q317399)

When you install Microsoft .NET Framework Service Pack 1 (SP1), this automatically sets a new default security policy, replacing the previous security policy that was in effect. The change in default security policy disallows managed code downloaded from the Internet zone from running (as configured on the Security tab under Internet Options in Microsoft Internet Explorer). Previously, this code was allowed to run with a limited set of permissions roughly analogous to the permissions that script...

The XML Signature and XML Encryption standards are being used extensively as building-block technologies. Microsoft® Office InfoPath™ uses XML signatures to sign partial or whole forms. Web services use XML signatures to sign SOAP messages and XML encryption to encrypt them. The XML manifests for ClickOnce®-based applications, new in Visual Studio® 2005, also use XML signatures. The .NET Framework 1.x includes an object model for the XML Signature standard, and the .NET Framework 2.0 adds additi...

Over the years I've had many people ask me to write about GINA, the Graphical Identification and Authentication component that serves as the gateway for interactive logons. This month I'll begin my coverage of this topic to help you get started if you're tasked to build such a beast. I'll build a sample called KIOSKGNA, which is the simplest possible GINA implementation I could think of. Next time I'll introduce a sample called FULLGINA, a more fully featured GINA. The examples and code snippets...

In a typical high-tech organization, often there is a need for engineers to visit client sites for installation or on-site support for periods of days or months.In such scenarios there are requirements for a means to track job requests, check existing schedules, allocate human resources for sales-service-installation visits, check resource utilization, timely reminders and so on. In this article, Paresh Joshi will develop a system using ASP.NET that addresses these needs with an in-built work fl...

Security has always been a top issue for all kinds of applications, especially Web applications. Web apps are accessible to almost the entire universe and are open to attack.

Web Services is a current hot topic because of its interoperability, ease of consumption, use of standard Web protocols, seamless integration with heterogeneous systems, etc. Therefore more platforms are now incorporating Web Services into their architecture. And with that greater amount of use, the need for security...

The Security Support Provider Interface Revisited

Read Reviews | Write Review |   Your Rating: 

This is a follow-up to an earlier column on the Security Support Provider Interface (SSPI), the Windows® equivalent of the GSSAPI interface. It's extremely unfortunate for developers trying to write platform-neutral code that they are not equivalent, but back when SSPI was developed, platform neutrality was not a priority. Way back in August 2000, I explained the need for the SSPI interface; namely, it abstracts the differences between various authentication protocols. I also showed how you can...

Like many developers of managed code, I frequently interact with system internals. One day, while working on the managed access control list (ACL) class library for the Microsoft® .NET Framework 2.0 (see my article in the November 2004 issue of MSDN®Magazine), I had to implement support for changing a security descriptor on an object. In some situations, this operation requires enabling Take Ownership and Security privileges. I poked around and discovered that there was no existing support in th...

Exploring Handle Security in Windows

A while ago I did some research trying to figure out how security works with handles in the face of interprocess communication, impersonation, handle inheritance, and the powerful DuplicateHandle API. This month I'll present my findings along with a program that you can use to explore the issues further. I used to speculate about how security works with built-in operating system objects (processes, semaphores, registry keys, files, window stations, and so on). But only after I wrote a program to...

Improve Manageability through Event Logging

The three traditional pillars of computing security are confidentiality, integrity, and availability. Often when I speak of availability, I talk about obvious threats such as denial of service attacks, but there's more to it than that. An application that requires high availability must be resilient to abnormal situations. If something goes wrong, an administrator must be able to sort out a solution quickly. Applications designed with management in mind tend to be more highly available, partly b...

One of my favorite new features in Windows Vista™ is Windows® Speech Recognition, which allows you to operate your computer using only your voice, including dictating text into e-mail messages or other documents. Windows Speech Recognition uses the Text Services Framework (TSF) to insert, select, and correct dictated text. TSF is a scalable framework for the delivery of advanced text input technologies. It provides a standardized method for text services—such as voice recognition, handwriting re...

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. So I've pulled together a number of examples where fully trusted code can skirt around common language runtime (CLR) security features, starting each with a question that seems to have an obvious answer....

The Security Infrastructure of the CLR Provides Evidence, Policy, Permissions, and Enforcement Services        
Total Hits: 3  |  Today: 0 Author: Don Box       Rating:  
Read Reviews | Write Review |   Your Rating: 

The common language runtime of the .NET Framework has its own secure execution model that isn't bound by the limitations of the operating system it's running on. In addition, unlike the old principal-based security, the CLR enforces security policy based on where code is coming from rather than who the user is. This model, called code access security, makes sense in today's environment because so much code is installed over the Internet and even a trusted user doesn't know when that code is safe...
