  A social network is a social structure made up of individuals or
organizations called nodes, which are connected by one or more specific types
of interdependency, such as friendship, common interest, and exchange of
finance, relationships of beliefs, knowledge or prestige. A cyber threat can be
both unintentional and intentional, targeted or non targeted, and it can come
from a variety of sources, including foreign nations engaged in espionage and
information warfare, criminals, hackers, virus writers, disgruntled employees
and contractors working within an organization. Social networking sites are not
only to communicate or interact with other people globally, but also one
effective way for business promotion. In this paper, we investigate and study
the cyber threats in social networking websites. We go through the amassing
history of online social websites, classify their types and also discuss the
cyber threats, suggest the anti-threats strategies and visualize the future
trends of such hoppy popular websites.
