Abstract— Computer viruses are widely recognized as a significant computer threat. The “birth rate” of new viruses is high and increasing due to global connectivity, and technology improvements can accelerate their spread. In response to this threat, some contemporary research efforts are aimed at creating computer virus immune systems. This paper analyses the computer viruses and attacks and also some countermeasures to prevent them. In particular, we discuss Intrusion Detection and Prevention techniques for handling web based attacks and to patch up different kinds of vulnerabilities in computer system.

Web based system makes the next way of computing. Global prosperity and even faster pace of business are driving the desire for employees, partners and customers to able to communicate from different location in this world.
With this phenomenal growth of computing devices, the threat of viruses is likewise growing. New platforms such as MAC OS of Apple and Microsoft Windows are highly attractive targets to virus and Trojan writers. As technology in the world of networking industries advances, virus writers have plenty of room for growth. Worse thing is security measures such as firewalls and virus scanners i.e. antivirus softwares are not widely used. The future may be even worse. With distributed programming platforms such as .NET, combine with Microsoft’s Windows platform the potential for viruses is even greater.

On the surface, the vulnerability of wireless devices to viruses and malicious code threats appears to follow the same patterns of vulnerabilities that the wired world has experienced. Yet, upon closer inspection, the vulnerabilities are more numerous and complex and can be categorized into three groups:
• Application-based threats
• Content-based threats
• Mixed threats…...

...XML / XSLT What is XML, and why has it gained so much momentum? XML, or Extensible Markup Language, is an excellent way of representing data in a structured format. The most popular application of XML is for data-exchange. Like HTML, XML is also a textual, tag-based "markup" language. However, unlike HTML, which has a fixed set of tags and focuses on "presentation", XML does not have any fixed set of tags, and XML is all about "data". It is possible to create our own tags, and write data inside these tags in an XML document. The XML data is structured in a hierarchical format, and there are many "parsers" available that allow easily getting to the data values. In addition to data-exchange, XML is being used for various other purposes, such as content management, XML-based configuration files, eBusiness, document publishing, application integration, and most notably XML-based messaging or Web services. Some of the reasons behind XML's success include: • The ability to define and use our own tags makes XML "extensible", and self-describing. • XML's textual nature makes it highly portable allowing us to send and receive data from one platform to the other without any issues (such as encoding). • The availability of many free XML parsers and processors, makes it really easy to create, read, and manage XML documents. • As mentioned earlier, XML is all about data. Separating "presentation" from the actual "content" has many benefits, including the......

...Opportunities to improve Communication and Perceptions and MPC: - Establish direct connects7: It would be a good idea for Bob & Mike to make special trips to have a first-hand understanding of the ground reality in Detroit and San Francisco. This would reduce the lack of communication connections due to the distributed nature of MPCs businesses and also the fact that Al has not been able to spend the necessary time at these locations. This will help Bob & Mike evaluate the real issues and the extent to which Al is aware and in-charge of the situation. They might as well find that Al has things under control and the regional managers report the regular status to Al and Al does provide the necessary guidance, albeit remotely - Upward Communication: It is seen that a majority of the line functions in the organizations report into Al. Since Al is a very senior executive, the Board needs to know Al’s performance accurately8. Direct connections with regional offices should provide a clear picture on Al’s day to day effectiveness. It is highly recommended that Al’s loyalty to the company, his excellent track record and his willingness to work in midst of serious issues on the personal front should be communicated to the Board along with news that he just helped close a much-awaited $15MM deal in Detroit. - Support Structures: The situation that MPC is facing with one of its senior executive is not new to an Organization; in fact this could be faced by anyone in the Organization.......

...Int Programming--Malone Basics of Java Programming (A Work In Progress) What Constitutes a Java Program? A Java program consists of one or more source files. Each source file is called .java, where is the name of the class contained in that source file and .java is the extension that identifies the file as a Java source code file. In general, each source file contains one class. The name of the class must match the name of the file (without the extension) exactly. To execute a Java program, you first need to compile the source code into byte code. Byte code files have the name .class. If you’re working from the shell, this is done using the javac command (where “c” is for compiler). Usually we will be compiling using the Xcode IDE. Once compiled, the program is executed using the Java interpreter (a.k.a. the Java Virtual Machine or JVM). From the shell, the JVM is invoked with the “java” command. Again we will usually be doing this with the Build and Go or Debug options of the Xcode IDE. A Java program must have a routine called main(), which is the starting point for program execution. main() will always look something like this: public static void main (String args[]) { // insert code here... System.out.println("Hello World!"); } Source Code Formatting Keep in mind the following when writing Java source code: Java is case sensitive (“foo”, “Foo”, and “fOO” are all considered to be different in Java). • Every line of code in Java must end in a semi-colon (“;”). • Java......

Trying to manage your business without referral is a serious lost opportunity. Referral can increase your business by 20% and referrals are proven to start school with an 80% start rate.

Become a Web Developer

...Project Objectives! Our aim is to design and develop a simple site design with a modern layout that's conducive to CMS systems like WordPress. We won't be applying any wild and crazy style effects in our design (the point here is to keep it simple), but we are going to approach the entire process, from start to finish, as a study in layout and a proper use of margins and padding. We'll be using the 960 grid system from start to finish, so if you've ever wondered what it's like to use the system, now's a great time to learn! We'll be making a few deviations from the norm, but for the most part we'll be using 960gs in the design and coding phases. Once you guys/gals are done, you're welcome to customize the design all you want with your own fonts, colors, styles and textures! Remember, this is just a starting out point - you're welcome to go as nuts as you want when it comes to the personality of your own version of the design. A Brief Course Outline. We might break this up differently once we hit the coding phase, but this should give you a good idea of where we're heading with this series: • The Design Phase • Session 1: Laying The Groundwork and Designing the Homepage • Session 2: Designing the Support Pages (Available Next Week) • The Coding Phase • Session 3: Slicing and XTHML Coding (Available Soon) • Session 4: Convert To a Wordpress Theme (Available Soon) Resources Used For This Project You can use your own resources if you'd like, but here's the full list......

...Estimating the Costs of a Reengineering Project Harry M. Sneed Anecon GmbH, Vienna Austria Institut für Wirtschaftsinformatik, University of Regensburg, Bavaria Email: Abstract: Accurate estimation of project costs is an essential prerequisite to making a reengineering project. Existing systems are usually reengineered because it is cheaper to reengineer them than to redevelop or to replace them. However, to make this decision, management must know what the reengineering will cost. This contribution describes an eight step tool supported process for calculating the time and the costs required to reengineer an existing system. The process is derived from the author’s 20 year experience in estimating reengineering projects and has been validated by several real life field experiments in which it has been refined and calibrated. Keywords: Reengineering, cost estimation, risk analysis, software measurement, gap analysis. It has been 15 years since the first studies on the economics of software reengineering projects appeared and since then a great deal of research has been done and a wide range of practical experience gathered.[1] At that time, reengineering projects were being calculated on the basis of the size alone, without consideration of complexity and quality. In the meantime, we have learned a lot more about how the complexity and quality of the software effect reengineering costs. The topic of estimating the costs......

How Real Estate Developers Can Improve Community and Political Relationships

...Joe Pohl REAL 470 Dr. Musil 5/12/15 Developer/Community Relations One of the first challenges a developer will face when taking on a new project will be getting the approval of the city councils and the citizens in the surrounding area of the project site. There have been many situations where development teams have done large amounts of work to put together what they believed to be a great plan, but ended up having their project shut down before they were even able to start because they could not get approval of the city boards. This causes a lot of time to be wasted, and can have other negative consequences for the development team such as unnecessary costs. There also have been examples of development projects where the team was able to strategically and effectively interact with communities in order to gain support from citizens and political bodies. Lessons can be learned from both the successful and unsuccessful development teams in order to determine what aspects of strategic interaction worked best, and what type of actions could have been done differently. Successful development projects occur at all different levels, and the size of the community that the development impacts can be at any size from a single neighborhood to an entire region. For example, there can be a region-wide sustainable urban planning project for an impoverished area, or there could be a simple construction project of a small-time business that could be beneficial for a......

App Developer

...A 12-year-old app developer TEDxManhattanBeach · 04:40 · Filmed Oct 2011 I've always had a fascination for computers and technology, and I made a few apps for the iPhone, iPod Touch, and iPad. I'd like to share a couple with you today. My first app was a unique fortune teller called Earth Fortune that would display different colors of earth depending on what your fortune was. My favorite and most successful app is Bustin Jieber, which is — (Laughter) — which is a Justin Bieber Whac-A-Mole. I created it because a lot of people at school disliked Justin Bieber a little bit, so I decided to make the app. So I went to work programming it, and I released it just before the holidays in 2010. A lot of people ask me, how did I make these? A lot of times it's because the person who asked the question wants to make an app also. A lot of kids these days like to play games, but now they want to make them, and it's difficult, because not many kids know where to go to find out how to make a program. I mean, for soccer, you could go to a soccer team. For violin, you could get lessons for a violin. But what if you want to make an app? And their parents, the kid's parents might have done some of these things when they were young, but not many parents have written apps. (Laughter) Where do you go to find out how to make an app? Well, this is how I approached it. This is what I did. First of all, I've been programming in multiple other programming languages to get the basics down, such......

Six Important Phases That Are Essential for Developers

...The systems development life cycle is important because it has six important phases that are essential for developers such as planning, analysis, design, and implementation. 1. Planning The feasibility study is sometimes used to present the project to upper management to get the approval and to have funding. Projects are evaluated in three main areas of feasibility: economical, organizational and technical. 2. Analysis The main objective of systems analysis is to determine where the problems in an attempt to help fix the system. 3. Design In systems, design functions and operations are described in detail, including screen layouts, business rules, process diagrams and other documentation. The output of this stage will describe the new systems as a collection of models or subsystems. 4. Build or coding Modular and subsystem programming code will be accomplished during this stage. Unit testing and module testing are done in this stage by the developers. This stage is intermingled with the next in that individual modules will need testing before integration to the main project. 5. Testing The code must be tested at various levels in software testing. Unit, system and user acceptance testings are often performed. There are many types of testing such as: Data testing, integration testing, user acceptance testing, performance testing and more. 6. Operations and maintenance The deployment of the system includes changes and enhancements before the sunset of the system...
