What is a data breach?
A data breach is a security incident in which a malicious actor breaks through security measures to illicitly access data.
Data about individuals—names, birthdates, financial information, social security numbers and driver’s license numbers, and more—lives in innumerable copies across untold numbers of servers at private companies, public agencies, and in the cloud. If someone who isn’t authorized to access personally identifiable information (PII) manages to get a look at it, that can have dire consequences both for the individual and for the organization that stored the data and was supposed to keep it safe.
