Protecting Your Account

The first step in keeping our private information safe is controlling the information we choose to put out online for the world’s consumption. The internet is forever, and it is at risk if the information is online. As a society, we have become accustomed to sharing every aspect of our lives online. Even more difficult, nearly every app and website require our personal information, such as our names, emails, and phone numbers. David Emm, a principal security researcher at Kaspersky, stated “…we need to control what we want to make public and what we don’t.” Threat actors increasingly recognize the power of social media platforms and their potential to get them closer to their economic, political, or social gains.
