The ultimate goal of wireless communication systems is to create a global personal and multimedia communication without any capacity issues.

Automated multilevel defence model to investigate packets for web interface

Web applications placed on server are subject to various forms of attacks. When a server is hacked, the client gets exposed to malicious servers. These malicious servers completely control the exposed and compromised client web servers through remote access of the SQL database connected to them. The aim of this paper is to develop and deploy an automated multilevel defence Intrusion Response Model which would filter the packets in the first stage, look for the malicious data hidden in the second stage, investigate packets for securing web server using client honeypot in the third stage and analyse the data stored in the repository of the client honeypot in the fourth stage. Hence, the paper offers simulated web based applications in order to detect, monitor and analyse any malicious activity. The different client honeypot are efficient up to 60%. As can be seen, by using the right mix of effective network management and fast analysis of packets, we can greatly reduce the level of false alarms up to 28%. This practice would make the system most effective.

Intrusion Detection System Using Genetic Algorithm for Cloud

Cloud and its transactions have emerged as a major challenge. This paper aims to come up with an efficient and best possible way to transfer data in cloud computing environment. This goal is achieved with the help of Soft Computing Techniques. Of the various techniques such as fuzzy logic, genetic algorithm or neural network, the paper proposes an effective method of intrusion detection using genetic algorithm. The selection of the optimized path for the data transmission proved to be effective method in cloud computing environment. Network path optimization increases data transmission speed making intrusion in network nearly impossible. Intruders are forced to act quickly for intruding the network which is quite a tough task for them in such high speed data transmission network.

E-commerce website quality assessment based on usability

Today website is considered as an image of an organization. For designing an effective website it is required to identify the need of the visitors of the website. In current scenario the objective of e-commerce websites is to provide the users or customers a platform where they can retrieve any information and also can perform other tasks like adding to cart, save for later, checkout, payment, tracking records and may more. In this paper, techniques like Adaptive Neuro Fuzzy Inference System Approach (ANFIS) and Analytical Hierarchy Process (AHP) were used to assess the usability of e commerce website and propose a model to successfully assess and compare websites on the basis of usability. First of all, the important factors related to usability from the literature or educational materials were identified. A survey using these factors as base was conducted which served as a valuable input from user for identifying the parameters affecting usability, which was further used in assessing the usability parameters of the e-commerce websites (such as Flipkart, Amazon, Snapdeal, Myntra). A Fuzzy inference system (FIS) file was generated using the parameters identified in the survey, member functions and other rules. Training data was generated using the survey conducted. ANFIS system used this training data and FIS file to create an optimal model for assessing the usability of the websites. This model can also be used to identify the important parameters to improve usability of the website using the valuable review of daily website users via the conduct of survey.

A heterogeneous wireless network integrating smartphones, WLANs and VANET to enhance on-road surveillance and security

In todays scenario, crime is widely prevalent in every sector of the society. However it has been observed that in most of the cases a vehicle was involved in some or the other way. To make the roads safer and to enhance the public safety on roads, various technologies have been combined which constituents Intelligent Transportation Systems (ITS) network. One example of this field is “Vehicular Ad hoc Networks” (VANETs) which is a subclass of “Mobile Ad hoc Networks” (MANETs). In VANET, automobiles act as mobile nodes and are capable of communicating with one another as well as stationary infrastructure, hence creating an autonomous and dynamic mobile network. This research paper focusses on the proposal of a model for on-road surveillance & security system by integrating various different wireless network technologies/devices, such as Smart phones, WLANs & MANET. The paper also discusses the insecure environment that stirred the need for an efficient surveillance system and how this model approaches to provide a solution. We have used MATLAB tool to simulate and validate the proposed model. The successful implementation of any such system will help in controlling the crime rate as well as it may also aid in providing necessary evidences.

The Cost-Benefit Analysis of Vulnerability of Web Server Through Investigation

With the rise of web applications, there has been a paradigm shift as web servers are no longer a technical requirement for any organization, but it is seen as an extension for business propositions. These web servers are designed with the basic function of hosting websites and applications such as gaming, data storage and enterprise applications. This paper attempts to investigate the various vulnerabilities of the web server and the path followed by the attacker to attack. The extensive survey has been done on the various methods of attacks which are an outcome of the loopholes in the design and architecture, deployment of the web server. If the components are designed and modeled taking into considerations the various vulnerabilities explained in the paper, the chances of attacks on the web server is minimized drastically. The paper also discusses the novel formula for the calculation of severity of attacks. This formula helps to assess the attack and is instrumental in the calculation of cost-benefit analysis.
