If you look what's out there in terms of security tools, it is slim pickings.
For Linux there's a lot of tools, but you have to be a rocket scientist to implement it.
What we need is a way to set up a honeypot/tar-pit on windows/OS X/Linux that is easy to understand, set up and operate.
The honeypot reports unwanted access attempts to Comodo, who in term compiles a secure list for the honeypot/tarpit clients out there to download.
Such a list is then at the disposal and can be used to populate a router's ACL etc.
Botnets are huge. We need the equivalent in defending against them.
