This year global cyber-war went mainstream. Banks were robbed by digital criminals, Yahoo confessed to losing half a billion consumer records, foreign attacks leaked documents from the Democratic National Committee and presidential candidate Hillary Clinton, and thousands of small businesses and enterprise companies lost millions of dollars.

Yet cybersecurity is complex, and learning and fundamentals—how hacking works, what attackers want, and how to protect against a data breach—is a daunting prospect for everyone from curious amateurs to IT pros. Even organizations as security-minded as banks "only cover about half of what really matters," said Ernst & Young cybersecurity expert Ertem Osmanoglu in a recent interview. "Cyber is truly a business issue that needs to be a bigger part of the end-to- end business workflow."

Osmanoglu acknowledges that technology evolves quickly and that 100 percent security is impossible. "Therefore, organizations must be capable of immediately dealing with incidents to minimize loss," he said, and advised organizations of all sizes to leverage new technologies to improve organizational understanding of cyber-risk. "While new technologies will allow organizations to detect and respond to threats in real time, organizations should prioritize protection of high value assets. Information protection can seem overwhelming to executives, but allocating additional dollars towards crown jewels is a place to start ... cyber is truly a business issue that needs to be a bigger part of the end-to-end business workflow. "
