Have you ever clicked a link in an email without thinking? Sent an attachment to someone who shouldn’t have it? Held a locked door open for someone who said they were delivering a package to your workplace? Security breaches like these can happen to anyone. While many cases involve technology, it’s much easier to trick a person than to hack a system. In fact, human error is the number one factor in security breaches, from cyberattacks to physical trespassing. And it only takes one person to cause damage to a whole organization. Everyone makes mistakes, and hackers are good at gaining your trust and getting you to do something you shouldn’t. Knowing what makes you vulnerable—and how to fix it—is the best way to prevent human error!
