这一节讲述如何保持您的计算机远离安全威胁。

Give a separate user account to each person

When Xubuntu is installed, it is set up for a single person to use. If more than one person will use the computer, it is best for each person to have their own user account. This way they can have separate settings, documents, and other files. If necessary, files can also be protected from being viewed or changed by non-administrators.

To set up user accounts, choose ApplicationsSystemUsers and Groups. You must be an 第 14 章 管理任务 to do this.

See the 第 16 章 用户和用户组 for more information on setting up user accounts.
