Attackers are taking this high usage of internet as an advantage and trying to attack the users. Attackers are infecting the vulnerable web applications by injecting malicious code into its webpages. Whenever user browses the infected website knowingly or unknowingly, the malicious code is downloaded into his system by exploiting the vulnerabilities in the browser. With this, attacker gets the control over the user’s system to perform malicious operations.Attacker may also use the infected system as a hop point for redirecting other users to his malicious server through which he can download the malicious codes. These kind of attacks are known as Drive by Download attacks. In recent times, Drive by Download is the major channel for propagating the malware. In this paper, JavaScript Defender is presented for analyzing and defending against the HTML and JavaScript based Drive by Download attacks. Read More Read Less

Abstract Introduced by Yao in early 1980s, secure computation is being one among the major area of research interest among cryptologists. In three decades of its growth, secure computation which can be called as two-party computation, or multiparty computation depending on the number of parties involved has experienced vast diversities. Research has been carried out by exploiting specific properties of functionalities... Introduced by Yao in early 1980s, secure computation is being one among the major area of research interest among cryptologists. In three decades of its growth, secure computation which can be called as two-party computation, or multiparty computation depending on the number of parties involved has experienced vast diversities. Research has been carried out by exploiting specific properties of functionalities and generic approach to achieve efficient practical secure computation protocols. This paper considers the application secure two-party computation of AES-128 for comparison of the above two approaches. Read More Read Less

Abstract Anomalies in computer networks has increased in the last decades and raised concern to create techniques to identify the unusual traffic patterns. This research aims to use data mining techniques in order to correctly identify these anomalies.

Anomalies in computer networks has increased in the last decades and raised concern to create techniques to identify the unusual traffic patterns. This research aims to use data mining techniques in order to correctly identify these anomalies. Weka is a collection of machine learning algorithms for data mining tasks which was used to identify and analyze the anomalies of a data set called SPAMBASE in order to improve this environment.
