It is difficult to come up with a precise definition of cloud computing. In general terms, it’s the idea that your computer’s applications run somewhere in the "cloud," that is to say, on someone else’s server accessed via the Internet.

On September 7, Equifax, one of the three national credit reporting agencies (credit bureaus), reported a data breach that may have compromised the personal information of 143 million individuals.  That’s almost half the population of the U.S.  The compromised data is said to include Social Security numbers, birth dates, addresses and driver’s license numbers.  In some cases, the compromised data may also include credit card numbers.  The number of people impacted and the sensitivity of the breached information may make this the most significant data breach ever.
