The answer to that question varies depending on the nature of the data itself. Some data is regulated by the government. If that data is compromised as a result of a security breach, your company could be in violation of a num- ber of laws and regulations. Data loss could also mean that your company couldn’t make accurate and timely ﬁnancial reports or even respond to a judge’s subpoena. And if the data is about your company’s newest won- der drug or next generation electronic gadget, losing that information or letting it fall into the wrong hands could cost millions. Data loss can have serious repercussions. A couple of years back at a computer security symposium, attendees were asked what the worst type of data loss would be.
