Security in social media

          Security in social networks is an increasingly important factor for more and more users worldwide. It is also normal, since people share a lot of personal information, to which not only friends and family have access, but also strangers, who create threats. Most social networks are under threat, whether it's connection issues or Java vulnerabilities that hackers can exploit. Although social networks like Facebook have their own system where they store user data, and many unsafe external applications access a wealth of information because users give them too many permissions. Once they are inserted into the application storage system, no one can control what happens to them.
