Abstract: Many people depend on websites to perform their daily work. In spite of the rigorous testing of the websites for security flaws, some flaws still exist that prevent the secured usage. Many have discussed on infected websites and how to maintain user's privacy. The prevalence of user visible security design flaws will be examined, by observing several websites. After examining the flaws, steps to overcome security flaws will be developed in this paper. The results will give a brief...
Welcome to the chapter, Safeguarding a Computer and Recovering from Disaster. This chapter describes methods to protect a computer and take preventive measures in case of a disaster. In this chapter, you will learn to: Describe various recovery techniques in Windows XP Professional Explain Windows XP Professional boot process Configure advanced startup options Describe the backup utility Explain Automated System Recovery (ASR)14.1 IntroductionImagine a situation where a computer that does not...
This weakness may be caused by software bugs and flaws in the design of the system , The reason some weaknesses to the wrong data entry , Where that often allows direct execution of commands or language SQL statements , Often allows Weaknesses an attacker to circumvent the program to bypass screening access . There are a number of weaknesses that your computer or your network vulnerable : 1 . Validation error such as data entry errors resulting from code format text codes . 2 . Deal wrong with...
Explain the obstacles and advantages of the competing technologies J2EE and Microsoft's .NET with respect to teaching andlearning in a university environment J2EE and Microsoft .Net are two competing technologiesthat aim to achieve the same thing. That aim is to simplify development of webapplications by providing a standard set of components and services that can beaccessed regardless of operating system. This enables focus to given to thebusiness logic and development of it. The benefit of...
CVE stands for Common Vulnerabilities and Exposures.CVE Vulnerablities and exposures CVE is a dictionary of common names such as this CVE Identifiers for publicly known information security vulnerabilities, while its common configuration enumeration provides identifier for security configuration exposures and vulnerability issues (CVE, 2010). CVE common identifier facilitates the exchange of data across separate network security database, tools and provide the bases for assessing the...
Crthogonal Frequency Division Multiplexing is an effective modulation scheme to improve the performance of a communication system over wireless multipath fading channels. The aim of this paper is to analyze the effect of phase noise using different phase noise models due to local oscillators, and also propose the compensation technique for each model over fading channels. Also this paper analyzed the effect of phase noise over different channel conditions. The effect of phase noise in OFDM is...
Software Engineering Dissertation. Project Title: A web-based student monitoring system I need to write a Project Definition Document (1000 words). Project Title: A web-based student monitoring system Background of the project: I need a system by which personal tutors can monitor the attendance of their first-year students, to detect those who are not keeping up as early as possible. A partial system exists: it offers some queries, but is too inflexible for adding and modifying data. The...
In present, there is an increase in the ratio of applications based on heterogeneous multimedia traffic with new enhancements and conditions. The network traffic with different applications in accordance with the requirements in terms of delay, jitter, loss, throughput, interaction and reliability features. In the past, wireless local area networks with IEEE 802.11 standard did not support QoS management especially in case of voice, voice and delay sensitive application but due to the increase...
When developing a web site many things need to be considered for the elderly, the physically impaired and especially the disabled. Also to increase the accessibility of your web site a developer must take in consideration the user, the many ways the user interacts with the essentials components and how people with disabilities use the web. In order to completely understand the task at hand one must take in consideration these three major points - Firstly, web accessibility basically means that...
Abstract- This paper proposes a fully digital high performance variable speed drive of induction motor implementing based on a single chip DSP motor controller. Some important models and features of the Field Oriented control are analyzed in detail and the implementing flowchart is given. The proposed speed control algorithm programming in C is realized by the TMS320LF2407 DSP offering a fast current response. Simulation results show that the performance of Field Oriented control of induction...
