"Patrick Clawson, newly appointed chief executive at PatchLink, poured scorn on the panic associated with “zero day vulnerabilities” calling it “bullshit”.

“I’m calling bullshit on the whole zero day thing. These vulnerabilities are announced on that day, not released, it’s in the year running up to that date where they cause problems. By the time something like Slammer becomes well known, it is a nuisance, but [as an IT manager] what you have to worry about, is what you don’t know.”"
