Computer Software and Open Source Issues: A Primer

Abstract:

The use of open source software by the federal government has been gaining attention as organizations continue to search for opportunities to enhance their information technology (IT) operations while containing costs. For the federal government and Congress, the debate over the use of open source software intersects several other issues, including, but not limited to, the development of homeland security and e-government initiatives, improving government information technology management practices, strengthening computer security, and protecting intellectual property rights. Currently, the debate over open source software often revolves primarily around information security and intellectual property rights. However, issues related to cost and quality are often raised as well.

Open source software refers to a computer program whose source code, or programming instructions, is made available to the general public to be improved or modified as the user wishes. Some examples of open source software include the Linux operating system and Apache Web server software. In contrast, closed source, or proprietary, programs are those whose source code is not made available and can only be altered by the software manufacturer. In the case of closed source software, updates to a program are usually distributed in the form of a patch or as a new version of the program that the user can install but not alter. Some examples of closed source software include Microsoft Word and Corel WordPerfect. The majority of software products most commonly used, such as operating systems, word processing programs, and databases, are closed source programs.

For proponents, open source software is often viewed as a means to reduce an organization's dependence on the software products of a few companies while possibly improving the security and stability of one's computing infrastructure. For critics, open source software is often viewed as a threat to intellectual property rights with unproven cost and quality benefits. So far there appear to be no systematic analyses available that have conclusively compared closed source to open source software on the issue of security. In practice, computer security is highly dependent on how an application is configured, maintained, and monitored. Similarly, the costs of implementing an open source solution are dependent upon factors such as the cost of acquiring the hardware/software, investments in training for IT personnel and end users, maintenance and support costs, and the resources required to convert data and applications to work in the new computing environment. Consequently, some computer experts suggest that it is not possible to conclude that either open source or closed source software is inherently more secure or more cost efficient.

At this time there appears to be no centralized accounting of open source software throughout the federal government. However, the growing emphasis on improved information security and critical infrastructure protection overall, will likely be an influential factor in future decisions to implement open source solutions. The rapidly changing computer environment may also foster the use of a combination of open source and closed source applications, rather than creating a need to choose one option at the exclusion of another. This report will be updated as events warrant.
