The purpose of this research is to compare the commonly used social networking sites in terms of security features and to provide information about the security measures that can be taken and to raise awareness. In this direction, three popular social networking sites such as "Facebook", "Twitter" and "Youtube" are examined. In the study, the security and privacy features of social networking sites were presented comparatively and the data reached were interpreted and presented in tabular form. In this context, the ISO / IEC 17799 standard on information security has been observed.
