Comparing Java and .NET Security
Comparing Java and .NET Security: Lessons Learned and Missed Nathanael Paul David Evans University of Virginia Department of Computer Science [nate, evans ]@cs.virginia.edu Abstract Many systems execute untrusted programs in virtual machines (VMs) to mediate access to system resources. Sun introduced the Java VM in 1995, primarily intended as a lightweight platform for executing untrusted code inside web pages. More recently, Microsoft developed the .NET platform with similar goals. Both platforms share many design and implementation properties, but there are key differences between Java and .NET that have an impact on their security. This paper examines how .NET’s design avoids vulnerabilities and limitations discovered in Java and discusses lessons learned (and missed) from experience with Java security. Keywords: virtual machine security, Java security, .NET security, security design principles. 1. Introduction Java and .NET are both platforms for executing untrusted programs with security restrictions. Although they share similar goals and their designs are similar in most respects, there appear to be significant differences in the likelihood of security vulnerabilities in the two platforms. Figure 1 shows the number of major security vulnerabilities reported for each platform. As of December 2005, the Common Vulnerabilities and Exposures (CVE) database contains 150 entries concerning Java vulnerabilities [27], 38 of which we classify as major Java platform security vulnerabilities (we do not include application-specific bugs unrelated to the VM itself). The remaining vulnerabilities included in Figure 1 but not in the CVE are from Sun [39] (9 vulnerabilities) and McGraw and Felten [22] (5 vulnerabilities). The contrast with the .NET platform, in which no major security vulnerabilities have yet been found, appears striking. -

Understanding and Using Assemblies and Namespaces in .NET
Understanding and Using Assemblies and Namespaces in .NET Summary: Creating assemblies and namespaces in Microsoft Visual Basic .NET Objectives Understand assemblies in Microsoft® .NET. Understand namespaces in .NET. Use Microsoft Visual Basic® .NET to create and customize an assembly. Use Visual Basic .NET to create a namespace. Assumptions The following should be true for you to get the most out of this document: You are familiar with Visual Basic programming. You understand the basic concept of object-oriented programming. You have access to Visual Basic .NET. Contents Introduction Assemblies Namespaces Practice Creating an Assembly Practice Creating a Namespace What's New Since Visual Basic 6.0? Summary Introduction Microsoft .NET provides several ways to think of your code as more than just a bunch of disconnected lines. As a Visual Basic programmer, you're already familiar with the concept of a class, a section of code that defines an object and its behavior. But two of the higher-level groupings may be unfamiliar to you: An assembly provides a fundamental unit of physical code grouping. A namespace provides a fundamental unit of logical code grouping. As you'll see in this document, you can use Visual Basic .NET to create both assemblies and namespaces. You'll need to understand both of these concepts to be a productive Visual Basic .NET developer. Assemblies An assembly is a collection of types and resources that forms a logical unit of functionality. All types in the .NET Framework must exist in assemblies; the common language runtime does not support types outside of assemblies. Each time you create a Microsoft Windows® Application, Windows Service, Class Library, or other application with Visual Basic .NET, you're building a single assembly. -
