I keep telling the story of attempting to buy some enterprise routers. I would logon to my distributor's website, click on the CISCO SELECT range, and get blocked from the site for an attempted SQL injection ("SELECT" in the query string). On the topic of mod_security in general, something like half of these are .php urls, and there's a good chance many readers aren't even running a php interpreter. Somewhere, there's a person attempting to convince the reader that that is exactly the sort of malicious traffic you need a WAF for.
