With Internet-shattering distributed-denial-of-service (DDoS)
attacks, troves of records leaked through data breaches, and
a renewed focus by organized cybercrime on business targets,
2016 was a defining year for security. Indeed, in 2016 more than
4 billion records were leaked, more than the combined total
from the two previous years, redefining the meaning of the term
“mega breach.” In one case, a single source leaked more than
1.5 billion records.
