It is a kind of common technique for a hacker to break into remote systems and to get root privileges using buffer overflow on UNIX suid programs .

通过对UNIX的suid程序使用缓冲区溢出攻击已成为黑客入侵远程系统并获取root权限的常用技术。

While suid and sgid are handy , and even necessary in many circumstances , improper use of these access mode can allow breaches of a system 's security .

虽然suid和sgid很便利，甚至在很多环境下是必需的，但是这些访问模式不适当的使用会造成系统安全上的漏洞。

For example , one common practice is to set the SUID bit for the KPPP Internet Connection Utility so all users can use it to dial in to the Internet .

举例来说，一个常见的做法将设定KPPP因特网连接公用程式如此所有使用者的SUID位元能使用它拨在对因特网。

Given this , you will not be surprised to learn that the crontab command , like the passwd command , is an suid program that runs with root authority .

When an executable program has the suid access modes set , it will run as if it had been started by the file 's owner , rather than by the user who really started it .

当可执行的程序设置为suid访问模式，它就会开始运行，好像是由文件所有者启动而不是由真正启动它的用户启动。

All the set user ID ( SUID ) bit commands and programs shipped in AIX V7.1 have this feature enabled automatically , and no further configurations are required from an end user .

If the file is executable , the suid or sgid bits , if set , will be displayed as lowercase s , otherwise they are displayed as uppercase S.

如果文件是可执行的，suid或sgid位如果已设置，将会显示为小写的s，否则就显示为大写的S。

Applying data mining algorithm to intrusion detection is a major research direction in computer security . Especially , when using data mining algorithm such as association analysis , sequence mining to analyze suid programs in Unix environment , the future is much promising .

将数据挖掘方法应用于入侵检测中研究的一个重要方向是，对Unix环境下特定程序运用关联、序列等数据挖掘算法。

It is displayed in a long directory listing in the place of the executable flag for other users ( the last character ), with the same meaning for upper and lower case as for suid and sgid .

它显示在其他用户的可执行标识中（最后的字符）的长目录清单，而且suid和sgid的大小写意义相同。

The suid and sgid bits are set and reset symbolically using the letter s ; for example , u + s sets the suid access mode , and g-s removes the sgid mode .

suid和sgid位使用字母s在符号上进行设置和重设；例如，u+s设置suid访问模式，g-s删除sgid模式。
