有关信息安全的应用程序级别 [英] Application-level regarding information security

问题描述

我正在研究Web应用程序(网站)，并希望在其上应用有关安全级别的一些建议.
这些是需要做的一些事情:
1.谁不在局域网中谁就可以登录系统
2.谁在局域网上什么时候可以登录
3.这两种情况下谁都可以登录(在LAN上，而不在LAN上)

如果您在可以更好地保护Web应用程序安全的同时，还得到其他一些好的建议，链接或Tuto，请给我建议.

Hi I am working on web application(Website) and want some advice on security level to be applied on it.
These are some of the thing that need to be done:
1.Who can logged in the system when he is not on the LAN
2.Who can logged in when is when is on LAN
3.Who can logged in, in both cases (on LAN and not on LAN)

If you got other nice advice, links, or tutos, in the away that I can better secure the web application, please advice me.

推荐答案

这种类型的安全性是相当复杂，但是我确实知道需要它.

基本上，您需要查看请求的原始IP地址. IP地址范围是可路由和不可路由的.所有可路由地址都是基于Internet或WAN的地址.所有不可路由的地址都是基于LAN的地址.您需要查看请求的IP范围，并确定请求的来源(WAN或LAN).然后，您需要查看是否允许用户从WAN或LAN输入并应用正确的操作方法.

这里是要注意的问题，这仅适用于IPv4.我对IPv6的研究还不够深入，无法弄清楚如何进行这种尝试.您可能需要考虑在物理网络层执行此操作.

另一个选择是运行多个网站.您可以将WAN流量转到一个网站，将LAN流量转到另一个网站.每个Web服务器可以维护自己的授权用户，因此您可以相应地应用安全性.

虽然我确实知道这样做的必要性，但我的建议是认真地重新考虑您的安全模型，并确定您是否真的需要这种复杂的安全性.

This type of security is rather complex, but I do understand the need for it.

Basically, you need to look at the originating IP address for the request. There are IP address ranges that are routable and non-routable. All routable addresses are internet or WAN based addresses. All non-routable addresses are LAN based addresses. You need to look at the IP range of the request and determine where the request is coming from (WAN or LAN). You then need to look up if the user is allowed to enter from the WAN or LAN and apply the correct course of action.

Here is the catch, this only works for IPv4. I haven''t studied enough on IPv6 to figure out how to attempt this. You may need to consider doing things at the physical networking layer to achieve this.

The other option is comes into running multiple websites. You could have your WAN traffic go to one web site and your LAN traffic go to another web site. Each web server could maintain their own authorized users so you can apply security accordingly.

While I do understand the need for this, my suggestion is to seriously rethink your security model and decide if you really need such complex security.
