A very simple question here, with no right or wrong answers. Having read the article about the Target breach, whose fault do you think was it? Explain the basis of your inclination, the rationale. If you want to assign fault to multiple parties, that's fine, just provide a rough estimate of how much fault you would assign to each. Was this attack avoidable why, or why not?

The answer should be from 100 to 150 words.
