Abstract The impact of Online Social Networks (OSNs) on human lives is foreseen to be very large with unprecedented amount of data and users. OSN users share their ideas, photos, daily life events, feelings and news. Since OSNs’ security and privacy challenges are more potential than ever before, it is necessary to enhance the protection and filtering approaches of OSNs contents. This paper explores OSNs’ threats and challenges, and categorize them into: account-based, URL-based and content-based threats. In addition, we analyze the existing protection methods and highlight their limitations and weaknesses. Based on that, we propose a comprehensive, user-level, proactive and real-time OSNs’ protection system, called Hybrid Real-time Social Networks Protector (HRSP). HRSP has three components; a user-level security protocol and two classification models. The protocol defines a structure for OSN’s cryptographic services, including encryption, access control and users’ authentication. The classification models employ machine learning, black lists, white lists and users’ feedback, in order to classify URLs into: Benign, Risk and Inappropriate classes, and contents into: Benign, Hate speech and Inappropriate classes. We constructed two data sets of 150,000 URLs and 22,000 tweets to build and test the two classification models. Results show an overall accuracy of 93.2% for the URL model and 84.4% for the content model, while the protocol implementation produces compatible size and time overhead. The components of HRSP are integrated and have compatible design with OSN platforms. Keywords Online social networks · URLs’ security · OSN content classification

Browsing OSNs is considered as one of the most preferred and popular online activities, with high user engagement rates, attractive interfaces and expanding the accessibility from mobile devices. OSN accounts, private websites and blogs are widely used in different demands, in which they are satisfying their users need; starting from social relationships with family and friends, up to commercial E-marketing, social events, education, media press and even politics declarations. Popular social networks include (Jin et al. 2013): Facebook (“Facebook—log in or sign up” 2018), T
