Being from the Hawaiian Islands, the annual gathering of the Kohola (humpback whales) is always a spectacular view. They can get over half their body out of the water and administer a cannonball body slam splash like you've never seen before. Most of the internet thinks they breach to either see what's up (so to speak), let other whales know they are around (if the haunting squeal isn't doing it) and most common, to relieve the body of lice, parasites and barnacles.
While nature's breaches are unmatched, many internet security breaches are run of the mill leakages.
Miscellaneous errors like sending an email to the wrong person
Crimeware (malware aimed at gaining control of systems)
Physical theft or loss
Web app attacks
Denial of service attacks
Payment card skimmers
The really cool thing about the 9 attack patterns is that Verizon has also charted the frequency of incident classification patterns per industry vertical. For instance, in financial services 75% of the incidents come from web application attacks, DDoS and card skimming while retail, restaurants and hotels need to worry about point-of-sale intrusions. Utilities and manufacturing on the other hand get hit with cyber-espionage. Overall across all industries, only three threat patterns cover 72 percent of the security incidents in any industry.
Once again, no one is immune from a breach and while media coverage often focuses on the big whales, the bad guys are not targeting organizations because of who they are but because a vulnerability was found and the crooks decided to see if they could get more. This means that companies are not doing some of the basics to stay protected. For the 2014 analysis, there were 1,367 confirmed data breaches and 63,437 security incidents from 50 global companies.
For the most part, the fixes are fairly basic: Use strong authentication, patch vulnerabilities quickly and encrypt devices that contain sensitive information. I've barely scratched the surface of the report and highly suggest a through reading.
