Know the risks
It all starts with the awareness of the risks along with the realization that everybody is a potential target. Much of what we do every day involves the internet positively in one way or another. On the other hand, the digital world is also inhabited by criminals who never miss a chance to steal fellow netizens’ data or money, or both. First of all, then, it pays to be clear-eyed not just about the benefits, but also about the security and privacy risks of cyberspace.
This ties in with the fact that attackers deploy ever more advanced tools and techniques to attack their targets. While we hold no sway over attackers’ capabilities and incentives, we can make their “job” harder by acknowledging and addressing the vulnerabilities in ourselves, as well as in our devices and software.
