This will help digital forensics investigators to predict, detect and even prevent any criminal activities in different forms.

In order to deal with the forensic implications of social networks, current research on both digital forensics and social networks need to be incorporated and understood. The data generated through the use of these technologies need to be analyzed for forensic purposes when criminal and terrorist activities are involved. Social networks in any form, specifically online social networks (OSNs), are becoming a part of our everyday life in this new millennium especially with the advanced and simple communication technologies through easily accessible devices such as smartphones and tablets. Furthermore, we suggest future research directions. We also offer simple-to-implement recommendations for OSN users which can improve their security and privacy when using these platforms. In addition, we present an overview of existing solutions that can provide better protection, security, and privacy for OSN users. In this paper we present a thorough review of the different security and privacy risks which threaten the well-being of OSN users in general, and children in particular. These risks become even more severe when the users are children. This information, if put into the wrong hands, can be used to harm users both in the virtual world and in the real world. According to recent studies, OSN users readily expose personal and private details about themselves, such as relationship status, date of birth, school name, email address, phone number, and even home address. Many online social network (OSN) users are unaware of the numerous security risks that exist in these networks, including privacy violations, identity theft, and sexual harassment, just to name a few.
