The Data Tethers project is building an operating system that prevents loss of sensitive data when portable computers or storage devices are lost or stolen. Loss of such information is commonplace and often very damaging. Data Tethers addresses this problem by ensuring that when a portable device leaves a secure environment, sensitive data is not allowed to go with it. Many organizations have policies saying that such data should not leave their premises, but they have no enforcement mechanism. Data Tethers provides that mechanism. Data Tethers must track data as it is copied from file to file, since the goal is to prevent data loss, not just to protect particular files. The system must deal with issues of data lingering on in deleted files, temporary storage locations, and other obscure places in a modern computer, since thieves will look for sensitive data in those places, as well. Data Tethers is being added to Sun Microsystem's Open Solaris, an existing operating system in common use, and will make use of Sun's standard mechanism for adding functionality to Open Solaris. The expected results of the Data Tethers project will be a working open source operating system that will allow the owners and curators of sensitive data to avoid loss of that data through loss of their devices. This system will be freely available to all through a well-known web distribution mechanism, and will also serve as a template for how other operating system providers can add similar services to their systems.

数据TETHERS项目正在建立一个操作系统，该操作系统可防止丢失或偷走的便携式计算机或存储设备时丢失敏感数据。丢失此类信息是司空见惯的，通常非常有害。 数据tethers通过确保便携式设备留下安全的环境来解决此问题，不允许使用敏感的数据。 许多组织的政策说，这种数据不应离开其前提，但没有执行机制。 数据tethers提供了这种机制。 数据tethers必须跟踪数据从文件中复制到文件，因为目标是防止数据丢失，而不仅仅是保护特定文件。 该系统必须处理删除的文件，临时存储位置以及现代计算机中其他晦涩的位置中徘徊的数据问题，因为盗贼也将在这些地方寻找敏感数据。 数据tethers被添加到Sun Microsystem的Open Solaris，这是一种常用的现有操作系统，并将利用Sun的标准机制来添加功能以打开Solaris。 数据TETHERS项目的预期结果将是一个有效的开源操作系统，它将允许敏感数据的所有者和策展人通过丢失其设备来避免该数据丢失。 该系统将通过众所周知的Web分发机制免费提供，并且还将作为其他操作系统提供商如何在其系统中添加类似服务的模板。
