There is no valid way to measure just how many networks are violated each day and data stolen or corrupted, since most companies decline to go public with that information unless it results in criminal prosecution.
Most prefer not to admit that their seemingly secure networks were breached unless they can also say they got the culprit. Ironically, the only way to put a dent in cybercrime may be to fess up when it happens and let the world know just how prevalent the problem is within the sanctums of businesses large and small. Such efforts won't stop network security breaches, but they may provide common ground for companies to at least slow it down.
This is the idea behind Verizon Business's most recent Data Breach Investigations Report, which highlights some of the work done by the company's forensics investigators to track down and document security breaches among its customer base.
