Abstract
A definition of modern social media leads to the characterization of advantages and disadvantages of social media in the workplace. The characteristics of social media are: reach, accessibility, immediacy, and permanence paradox. The extent of media invasion of privacy is discussed in this chapter, and ethical dilemmas are raised. Social networks are regarded as the main reasons for the decrease of productivity and other unanticipated confidential problems, which a company may face. Furthermore, the implications of security alerts lead to a dilemma between individual privacy and common interest. Different types of attacks might interfere with an existing functional network. Relevant current issues in Network Security include: authentication, integrity, confidentiality, non-repudiation, and authorization.
