A honeypot is used to attract and monitor attacker activities and capture valuable information that can be used to help practice good cybersecurity. Predictive modelling of a honeypot system based on a Markov decision process (MDP) and a partially observable Markov decision process (POMDP) is performed in this paper. Analyses over a finite planning horizon and an infinite planning horizon for a discounted...
In this paper, an efficient projection wavelet weighted twin support vector regression (PWWTSVR) algorithm is proposed. PWWTSVR determines the regression function by solving a pair of smaller unconstrained minimization problems in primal space, which can reduce computational costs. Classical SVR algorithms give the same emphasis to all training samples, which degrades performance. PWWTSVR gives samples...
The popularity and accessibility of Sina Microblog have attracted a large number of spammers to conduct spamming behaviors. They can spread advertisements, disseminate pornography, virus and expose phishing. All of these behaviors are extremely harmful to legitimate users. It is necessary to detect spammers from legitimate users in Sina Microblog. In this paper, we defined two kinds of spammers, advertising...
