Updated 7/7/2008 - See Updates area below
I've written a small app that allows IIS sites to block Chinese and Korean web sites with just a couple clicks. It's called IISIP and is found here.
Unfortunately up to 80% of spam and server attacks come servers outside the US. Even though ASP.Net blocks a most attempts, it still clutters up your event logs with tons of junk that makes it harder to see real site errors.
I know of no other free way to do this so easily which is why I wrote the app. If you try to do this yourself you run into the following problems:
- A lot of sample code is out there to program IIS, but hardly any of it is built into a ready to run tool. Using these bits of sample code is a pain and requires integration time and often fixing someone else's glitches. IISIP is ready to run, 32-bit and 64-bit Windows.
- Even if you have a tool to bulk block IPs, it takes time to build your own block list. What's needed is integration of known block list INTO the app so everything you need is in one place. Thankfully sites like okean.com are maintaining such lists, and I've integrated them into the app.
- A final requirement to make this process easy is the ability to support dynamic and local "IP feeds". For example rather than hardcoding the lists into the app, the latest versions are automatically downloaded. You can also add other feeds by dropping an .xml file into the IPFeeds folder. So if you have your own lists built ISSIP can use them.
I'd appreciate any feedback - The app works well for me but it is new so if you want to be super safe you can backup your metabase first.
