Forwarding proxy (or something) web server protection?

DeicistDeicist Registered User regular
Hi All,

I'm looking for an application to do a specific function, to save me rolling my own. First off, here's the background:

We currently run a web server application that's provided by a third party. There's a few instances of this app running on a server, each running on a different port (obviously). Now, in the logs for one of these instances we're seeing a lot of 'script kiddy' type attacks, requesting '/phpmyadmin/setup/setup.php' and so on. I'm not particularly worried about these attacks, however I'd like to do something proactive about them.

Here's what I'd like:

Something to sit in between the web server and the outside world, that checks incoming requests and, should they be 'suspicious' (ie: blacklisted useragents, blacklisted urls) drop the request and add the ip address to a blacklist. If the request is valid then forward the request to the web server and return the response.

Now, I know there's plugins / modules for IIS, Apache et al that will do this for those servers, however I need something that runs seperately and can protect any server sat behind it.

Is there anything like this out there?

    mod_proxy for Apache will probably do what you need here.

    http://httpd.apache.org/docs/2.0/mod/mod_proxy.html

    I've set up something similar before, using an Apache proxy to protect/filter access to certain web apps.

    Even easier would be to setup a cron to grep your logs for those common exploit attempts and block the IPs in the firewall. I've seen an increased number of those PHPMyAdmin sniffers going around. Luckily, our systems don't have PHPMyAdmin accessible via a common url like that, but I've thought about writing something for us to use.
