Multiple probabilistic packet marking (PPM) schemes for IP traceback have been proposed to deal with Distributed Denial of Service (DDoS) attacks by reconstructing their attack graphs and identifying the attack sources. In this paper, ten PPM-based IP traceback schemes are compared and analyzed in terms of features such as convergence time, perform...

Privacy settings are a crucial part of any online social network as users are confronted with determining which and how many profile attributes to disclose. Revealing more attributes increases users’ chances of finding friends and yet leaves users more vulnerable to dangers such as identity theft. In this paper, we consider the problem of finding t...

Users of online social networks often adjust their privacy settings to control how much information on their profiles is accessible to other users of the networks. While a variety of factors have been shown to affect the privacy strategies of these users, very little work has been done in analyzing how these factors influence each other and collect...

A variety of schemes based on the technique of Probabilistic Packet Marking (PPM) have been proposed to identify Distributed Denial of Service (DDoS) attack traffic sources by IP traceback. These PPM-based schemes provide a way to reconstruct the attack graph — the network path taken by the attack traffic — hence identifying its sources. Despite th...

Users of online social networks are often required to adjust their privacy settings because of frequent changes in the users' connections as well as occasional changes in the social network's privacy policy. In this paper, we specifically model the user's behavior in the disclosure of user attributes in a possible social network from a game-theoret...

Sources of a Distributed Denial of Service (DDoS) attack can be identified by the traffic they generate using the IP traceback technique. Because of its relevance, the Probabilistic Packet Marking (PPM) schemes for IP traceback is an intensively researched field. In these schemes, routers are given the extra function of randomly selecting packets f...

Research in the field of keystroke dynamics (KD) has traditionally assumed impostor attacks to be originated by humans. However, recent studies have revealed that bots and various categories of malware have the capacity to implement intelligently crafted synthetic attacks against KD systems. In this paper we make a large-scale study of human typing...
