Abstract
In recent years, online social networks (OSNs) like Facebook are being used in an extensive manner. Besides providing friendship connection between two individuals, OSNs allow a set of multiple individuals to connect in a group. Sometimes these groups are open for all to join, whereas in some cases these have closed community with some special attention. The second type of groups mentioned above may become the target of intruders. The primary goal of these intruders is to collect confidential group information and transfer those to places that are vulnerable to the group’s interest. Also, a significant number of intruders can affect critical decisions and deviate the group from its original intent. In this poster, we introduce a set-cover based, novel infiltration technique which we call Set-Cover Attack to intrude into a target group. We also simulate our algorithm on a realworld social network group. In addition to this, we propose a defense mechanism which relies on a trust hierarchy of group members.

Our annual information security symposium will take place on April 3rd and 4th, 2018.
