Yes, the Internet is a War Zone
Here's a sample report of the numbers and types of attacks a server that gets about 400k requests/day experience...at least, it did before I blocked about 200 countries (the service is very specific to the US/CA/UK).
This report covers a 9 days period. It only covers web based attacks and not attacks on other ports or brute force attacks.
Maybe it's time for you to have a security audit??
