Root
In contrast to most other Linux distributions Puppy does not differentiate between a normal user and the administrator root. Rather you always works as root, which simplifies the use of Puppy. The question arises if it is unsecure to work as root and to have full access to all files, programs and data.
For the normal home user, there are no special risks compared to other Linux distributions. On the contrary, Puppy is probably a bit safer than many other distributions.
First let's analyze the risk of a distribution, which differentiates between user and root. The user works as a normal user, who does not have privileges to write/delete programs and system files. An intruder can compromise only the user’s files. However the intruder has an entrance to the system and can try to gain root-privileges (find the password file, use exploits to transfer malware code and so on), and afterwards try to get access to all files.
As long as Puppy starts from CD-ROM (and is not installed on the harddrive) the program-files and system-files are secure. Everytime you reboot any malware programs, which an intruder could have left, are gone. Of course your own files stored into the pup_save.3fs-file or on a harddrive can be compromised by an intruder, but this can happen to the normal user of another Linux-distribution as well. If you want to be safe from intrusion, store checksums of all files and backup your files regulary.

超级用户 （Root）
和其他Linux发行版本不同，Puppy的普通用户和超级用户没有区别。你就用超级用户登陆来做事情吧，这会让你使用Puppy变得更简单。那么，问题就出来了，“老用超级用户，会不会让我硬盘上的东东们随时有不测的风险？”
当然，普通用户的话和其他发行版一样，甚至可以说Puppy还更安全一点。
那么就一个Linux发行版来说，普通用户和超级用户的危险指数到底有怎样不同呢？如果是普通用户，它对程序和系统文件就没有写和删除的权限，黑客至多也就能黑到这个倒霉鬼，但是一旦坏人进屋了，它就会有机会去得到一些东西，比如password文件去破解超级用户的密码，最后控制整个系统。
这么说普通用户也挺危险的？不用怕，因为Puppy是从CD-ROM启动的，即使你被黑了，你一重启，黑客就死了。当然你保存在pup_save.3fs-file或者硬盘上的东西就有可能被黑，但是别的发行版本也会有同样遭遇。有一个笨办法，保存所有文档的checksums并且经常做备份。
