To access online for this services, the web browser is today’s almost unique software used. These days’ hackers know that browsers are installed into all computers and can be used to compromise a machine by distributing malware via … …Journal of Computer Science, Vol. 9, Issue 2 · 1 Apr 2013 · 6,810 accessesView PDFCite
Research ArticleOpen accessIn the abstractRandom Dummy Packet Distribution Approach for Detection of Routing Misbehavior in Mobile Ad Hoc NetworkT. Sakthivel, R. M. Chandrasekaran, S. Vijay BhanuA Mobile Ad hoc Network (MANET) works on the assumption that mobile nodes are cooperative. On the other hand, in practical, it may not be possible due to selfish, malicious and misbehaving nodes present in the network. These nodes are capable of interrupting the communication process and there is a potential for serious performance degradation. To improve the performance of … …Journal of Computer Science, Vol. 8, Issue 11 · 6 Nov 2012 · 6,977 accessesView PDFCite
Research ArticleOpen accessIn the abstractSurvey on Mobile Ad Hoc Network Attacks and Mitigation Using Routing ProtocolsS. P. Manikandan, R. ManimegalaiMobile Ad hoc Networks (MANET) due to its unpredictable topology and bandwidth limitations are vulnerable to attacks. Establishing security measures and finding secure routes are the major challenges faced by MANET. Security issues faced by ad hoc networks are node authentication, insider attack and intrusion detection. Implementing security measures is challenging due to the presence of limited resources in the … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 1 Sep 2012 · 6,856 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluating the Strengths and Weaknesses of Mining Audit Data for Automated Models for Intrusion Detection in Tcpdump and Basic Security Module DataG. Mohammed Nazer, A. Arul Lawrence SelvakumarProblem statement: Intrusion Detection System (IDS) have become an important component of infrastructure protection mechanism to secure the current and emerging networks, its services and applications by detecting, alerting and taking necessary actions against the malicious activities. The network size, technology diversities and security policies make networks more challenging and hence there is a requirement for IDS which should be … …Journal of Computer Science, Vol. 8, Issue 10 · 25 Aug 2012 · 7,132 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuzzy Based Secure Data Aggregation Technique in Wireless Sensor NetworksD. HevinRajesh, B. ParamasivanProblem statement: Secure data aggregation is a challenging task in wireless sensor network due to the facts like more complexity, greater overhead in the case of cryptographic techniques. These issues need to be overcome using efficient technique. Approach: We propose a fuzzy based secure data aggregation technique which was having 3 phases. In its first phase, it performs clustering and … …Journal of Computer Science, Vol. 8, Issue 6 · 17 Mar 2012 · 7,257 accessesView PDFCite
Research ArticleOpen accessIn the abstractMalware Detection Based on Hybrid Signature Behaviour Application Programming Interface Call GraphAmmar Ahmed E. Elhadi, Mohd Aizaini Maarof, Ahmed Hamza OsmanProblem statement: A malware is a program that has malicious intent. Nowadays, malware authors apply several sophisticated techniques such as packing and obfuscation to avoid malware detection. That makes zero-day attacks and false positives the most challenging problems in the malware detection field. Approach: In this study, the static and dynamic analysis techniques that are used in malware detection are … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 9 Jan 2012 · 9,150 accessesView PDFCite
Research ArticleOpen accessIn the abstractBehaviour Based Worm Detection and Signature AutomationMohammed Anbar, Selvakumar Manickam, Al-Samarraie Hosam et al.Problem statement: A worm is a malicious piece of code that self-propagates, often via network connections, to exploit security flaws in computers connected through the network. In general, worms do not need any human intervention to propagate and are considered a real threat to network assets and the properties of organizations. An Intrusion Detection Systems (IDSs) are employed to detect … …Journal of Computer Science, Vol. 7, Issue 11 · 6 Sep 2011 · 6,899 accessesView PDFCite

Research ArticleOpen accessIn the abstractAcknowledgment based Reputation Mechanism to Mitigate the Node Misbehavior in Mobile Ad Hoc NetworksK. Gopalakrishnan, V. Rhymend UthariarajProblem statement: The cooperation between the nodes is essential to discover and maintain routes in mobile ad hoc network. Due to the presence of misbehaving nodes, the node cooperation is not always guaranteed as the nodes agreed during the route discovery phase. This phenomenon results in frequent network partitioning and it makes the routing process difficult. It also degrades the … …Journal of Computer Science, Vol. 7, Issue 8 · 14 Jul 2011 · 6,570 accessesView PDFCite
