...Undersigned Project Committee Approves the Project Titled INTRUSION DETECTION AND PREVENTION SYSTEM: CGI ATTACKS by Tejinder Aulakh APPROVED FOR THE DEPARTMENT OF COMPUTER SCIENCE Dr. Mark Stamp, Department of Computer Science Date Dr. Robert Chun, Department of Computer Science Date Ms. Sunitha Thummuri, Cisco Systems Date APPROVED FOR THE UNIVERSITY Associate Dean Office of Graduate Studies and Research Date iii ABSTRACT INTRUSION DETECTION AND PREVENTION SYSTEM: CGI ATTACKS by Tejinder Aulakh Over the past decade, the popularity of the Internet has been on the rise. The Internet is being used by its clients to access both static and dynamic data residing on remote servers. In the client-server interaction, the client asks the server to provide information, and, in addition, the server may also request that clients provide information such as in “web forms.” Therefore, the Internet is being used for many different purposes which also include the web servers collecting the information from the clients. Consequently, attacks on the web servers have been increasing over the years. Due to the fact that web servers are now able to produce dynamic web pages based on the received requests, the web servers are now more vulnerable to attack than ever before. One of the ways to produce the dynamic web page is Common Gateway Interface (CGI) technology. Attackers take the advantage of CGI scripts to perform an attack by sending illegitimate inputs to the web server. This report...

...Server Side Security Unit 1 Individual ProjectRunning head: SERVER SIDE SECURITY UNIT 1 IP Server Side Security Unit 1 Individual Project American Intercontinental University IT465-1102B-02: Intrusion Detection and Prevention for Windows Security June 12, 2011 Basic Server Security The four basic necessities of server security include antivirus, strong passwords, firewalls, and critical updates. Antivirus software prevents infiltration and/or stops an attack completely. It will check a set of coding against a database of virus codes. It is important to use a well stocked virus database source. Strong passwords are typically ten to fourteen characters in length, a mix of numbers, symbols, upper, and lower cases lettering. Patterns, names, and identifiable information should be avoided (HostingHelpers, 2008). Critical updates include receiving security updates from an online source. These are done in forms of patches and/or updates that will correct coding, fix exploitable code, and a wealth of other things. These are vital to working with several applications. Firewalls are able to block unwanted traffic. These can help with security and keep random connection attempts form using up server and system resources (HostingHelpers, 2008). Firewalls Firewalls are very resourceful. Depending on the size of the company and users, choosing the correct firewall can be critical. There are many firewalls out there and companies that produce them both freely and paid. You...

...|Cloud Computing | Corporate Memo To, The Executive Committee Sub: Cloud Computing Arrival The cloud is here, but better exploitation of cloud computing will require improving IT cost transparency management practices to prevent overspending on IT, manage decentralized IT spending, and enable sustainable shared IT service organizations. There is considerable ambiguity in many enterprises about how to financially approach the cloud at the highest levels within IT and in corporate finance. In its various forms, cloud computing has the potential to radically change the way IT organizations budget, fund, charge back and manage IT spending and staff. From an economic perspective, cloud computing is a direct response to an IT marketplace that is addicted to "speed and quality" in enterprises that need a shift in focus to "cost and business value." Because the expectations of IT services have not been managed well throughout the years, there is now a gap between internal client expectations for service levels and the ability of enterprises to pay for this level of service. For 2011, the worldwide market forecast for public cloud is estimated at $89 billion, with a five-year compound annual growth rate (CAGR) of 19%. Compared to the forecast for all IT marketplaces in 2011 of $2.6 trillion, cloud represents only 3.5% of the IT marketplace...

...solution for students or their parents to view this data as information from one user friendly interface. The Arnewood School is a secondary school and sixth form college which has realised the need for this kind of information to me made available to students and parents via a secure, user friendly, single sign-on interface. This project aimed to produce a web portal which integrated and displayed information from preexisting and newly designed information systems in a way which was inline with the requirements of The Arnewood School and potential users. Due to the nature of developing such a system without having any knowledge of user requirements, a suitable methodology had to be selected which allowed for vague user requirements that could change at any time. Following this, background research and user requirements gathering was completed in order ensure the solution matched both the requirements of users and the requirements specified by The Arnewood School. Finally, the solution was designed and implemented before being suitably tested and evaluated. i Acknowledgements First and foremost I would like to thank Kevin McEvoy my project supervisor for his help...

...INTRODUCTION 1. INTRODUCTION Telecom Connections is a web based application through which user can effectively use the benefits of Telephone Provider. We have analyzed the needs of the users, and thus developed a web based application, for providing telephone connections and associated services online. Because now a days people became so busy with their work and they don’t want to waste their time by going and waiting for long time or waiting in a queue for applying for new connections or to get their bills or to give the complaints regarding the service. Also they are not sure whether waiting for that much time , they will get their turn or not. If so they will get out with frustration .By considering all this issues associated with the manual process we have developed a web application for the telecom users , where in the user can apply for new connections online , can view the bill status online , can send the feedback and do complaints regarding the service provided by the telecom company. 1. PURPOSE OF THE PROJECT: We are going to build an automated system where user can online apply for phone connections and they can view their telephone bills and they can also post the complaints details. EXISTING SYSTEM AND PROPOSED SYSTEM 2. EXISTING SYSTEM AND PROPOSED SYSTEM 2.1 PROBLEMS EXISTING IN SYSTEM: In existing system user has no option of online. He has to go to telecom office...

...KEL156 MARK JEFFERY A&D High Tech (A): Managing Projects for Success In his twelve years as a technology project manager at A&D High Tech, Chris Johnson had a strong track record of delivering projects on time and on budget. His techniques for project planning, estimating, and scheduling had become best practices at the St. Louis-based computer products company. He had just led a project team that successfully revamped the supply chain systems in less than eighteen months. He was especially proud since many observers had doubted that the project could be completed on time. As part of the strategic initiatives set forth by its CEO and founder, Ted Walter, A&D was to be second to none in utilizing technology to increase operational efficiency and reduce costs. The supply chain project therefore received notable attention in the boardroom and with its competitors. Time and again, Johnson was asked to tackle difficult assignments that were critical to the company’s growth and profits. He had already been mentioned as the successor to the vice president of e-business, Chuck Gagler, pending his retirement. (See Exhibit 1 for the A&D High Tech organizational chart.) In early May 2002 Johnson received an urgent message from the company’s CIO, Matt Webb. Webb asked Johnson to join him for a meeting with A&D’s senior managers to discuss taking over the company’s online store project. Johnson realized that up to that point the company’s top brass had virtually ignored the Internet...

...Development 6 Part II. Risk Analysis 8 Identification of Risk 8 Risk Analysis 9 Risk Management 10 Appendices 12 Appendix 1: Waterfall Approach 12 Appendix 2: Agile Approach 12 Appendix 3: Risk Management 13 References 14 Introduction This week’s assignment focus on the processes of system development and risk involved. For someone like me who never was part of the full design phase of the development process, I never knew the full concept of how the projects or applications were built from initiation. This assignment will allow me to have a high level understanding of the processes involved in system development, thereby allowing me to get a full grip of Project Management involved in the entire system development lifecycle. The 1st part of the assignment will allow me to identify and differentiate the 3 different development processes; waterfall, iterative and agile. I am hoping that after completing this part, I will somehow be able to identify the appropriate process for a particular application development. Among the 3 types of development approaches, the only one that I am familiar of is the waterfall approach. The 2nd part of the assignment will allow me to group the risk involved with the scenario presented. As I go through this part of the assignment, my aim would be to be able to group the risk accordingly for my future project so that I can address them accordingly. Scenario Suppose that your organization, a mall management company, wants...
