当我还在上中学的时候，县里的学校系统设置了所有的“安全”软件来防止孩子们接触部分互联网，或者改变配置设置和安装垃圾软件。除了该软件非常边缘的事实(一些shell修改可以通过在文件>保存框中单击鼠标右键绕过)，他们还设置了教师的密码来教学。

是啊，真的很安全。

About 3 years ago I built a site for a somewhat large non-profit organization in our state. When it came time to deploy the application to their web host server, I noticed an odd file named "cc.txt" or something obvious like that in their public site. It was under their web root, was getting served, and was a csv file of all their donor's names, addresses, credit card numbers, expiration dates, and CVV/CVC codes. I cannot count the number of times I brought the issue up - first to my boss, then our company accountant, the client's IT director, finally the client's President. That was 3 years ago. The file is still being served, it can even be googled. And it's been updated. I tend not to respond to their donation solicitations when I get them.

我们有一个旧的计算机集群，在我工作的一个实验室里没有运行。几个本科生认为，让它运行起来会很有趣，这样他们就可以学习一点并行计算了。他们让它运行起来，结果证明它非常有用。

One day I came in and was checking out the stats...It was running at 100%. Now this was a 24 node cluster and there were only 3 of us that ever used it so it was a little strange that it was running at this load. I started playing with it, trying to figure out what was loading it...turned out someone had gained access and was using it as their own little porn server and spammer. I asked the undergrads what kind of security they put on it, they looked at me and said "Security? We didn't think it would need any."

我给它加了个密码，就这样。把它用作色情服务器的人原来是一个本科生的朋友。

我将分享一个我创造的。种。

多年、多年、多年以前，我工作的公司需要在他们的ASP网站上建立索引。所以我去设置索引服务器，排除了一些管理目录，一切都很好。

然而，我不知道有人给了一个销售人员ftp访问网络服务器，这样他就可以在家工作，这是拨号的日子，这是他交换文件的最简单的方式....他开始上传东西，包括详细说明我们服务....标记的文档当人们搜索“成本”时，索引服务器就会索引并开始提供服务。

记住，孩子们，白名单不是黑名单。

不过这还不是我见过的最严重的安全漏洞。但这至少是我自己发现的最糟糕的情况:
