...Critical Information Systems Lance Kaea Carson BSA 310 May 15, 2011 Rich Harrell Critical Information Systems An Information System is an organizations framework for efficiency, productivity, and functionality. It “is a collection of hardware, software, data, people and procedures that are designed to generate and disseminate information and data that supports the activities of an organization” (International Graduate, 2011). Kudler Fine Foods is an organization specializing in providing domestic and imported sustenance to consumers. This paper clarifies an information system critical to their business process and examines how this system has an effect on the organization’s intricate structure. Information Systems Information systems used by organizations often follow a “traditional hierarchical structure” (Turban & Volonino, 2010. p.42). The structure commonly consists of seven functional types (1) Personal and Productivity Systems, (2) Transaction Processing Systems, (3) Functional and Management Information Systems, (4) Enterprise Systems, (5) Inter-organizational Systems, (6) Global Systems, and (7) Special Systems. Each category plays an essential role in the overall function of an organization when utilized. The development of an application program is used to execute or support a specific organization task or business process through the use of that information system. Although system types and applications can be independent of each other, most...

Since computers help us to deal with approximately all the major functions of our lives as well as are so inevitable that spending even a day or two away from the computer can leave us feeling powerless. In this prospect, many people control their routine lives by means of their personal computers. However, at the present computer security has become a very critical issue. Additionally, security refers to the technique to discover as well as stop illicit utilization of our secret information or computer. In this scenario, some preventive measures enable us to stop criminal users (as well known as "intruders") from accessing and using some part of our computer system. In addition, recognition of such intrusions helps us in deciding whether or not somebody tried to gain access into our computer system, if they were successful in their attempt, as well as what they could have acquired from the system (ComputerSecurityService, 2011), (Armor2net Software Ltd., 2004) and (Norton, 2001). In addition, the term “computer security” is very commonly used, though; the information and data saved on a computer are in danger to few risks unless the computer is connected to other systems...

...iPad’s Security Breach Zul-Jalaal Abdullah Strayer University Shelby Oaks campus Business Enterprise-508 April 21, 2011 Dr. Carolyn Tippett Discuss Goatse Security firm possible objective when they hacked into AT&T’s Website. Here’s what happened: Goatse Security discovered a rather stupid vulnerability on the AT&T site that returned a customer email if a valid serial number for the iPAD sim card was entered. (Arrington, 2010, para. 2). An invalid number returned nothing, a valid number returned a customer email address. Goatse created a script and quickly downloaded 114,000 customer emails. It was then turned over to Gawker, after, they say, AT&T was notified and the vulnerability was closed (Arrington, 2010, para. 2). Gawker published some of the data with the emails removed. Stated Goatse: “All data was gathered from a public web server with no password, accessible by anyone on the Internet. There was no breach, intrusion, or penetration, by any means of the word. ”(Arrington, 2010, para. 2). AT&T is characterizing the incident as “unauthorized computer “hackers” maliciously exploited a function designed to make your iPad log-in process faster by pre-populating an AT&T authentication page with the email address you used to register your iPad for 3G service (Arrington, 2010, para. 3). ”We don’t see much hacking here, and we don’t see anything really malicious (Arrington, 2010, para. 3). AT&T was effectively publishing the information on the open...

...THE EFFECTS OF COMPUTER GAMES TO THE ACADEMIC PERFORMANCE OF THE GRADE VI PUPILS IN ___________ELEMENTARY SCHOOL S. Y. 2010 - 2011 A Research Proposal Presented to the Faculty of the College Department ________________________________ Quezon In partial fulfillment of the Requirements for Research 2 ________________________ October 2010 Chapter I INTRODUCTION Background of the Study Computers are ubiquitous. As computers have become less expensive they have been purchased by more and more families for their homes. Because of this, many children begin to use computers at an early age. Even if computers are not available in their home, children almost certainly will begin to come into contact with computers in school. Some adults are amazed by how readily young children use computers. Many children find that using computers gives them a sense of power and accomplishment. And, unlike many adults whose first or primary contact with computers is work related, most children first use computers for entertainment purposes and games. This is by no means the only use that children have for computers. Because computer use is promoted in schools, and because computers are so ubiquitous, children have a great deal of exposure to them. Not everyone, however, is comfortable with the use of computers by young children. Some, including the Alliance for Childhood, have called for a halt to the...

...SEC 572 iLAB 1 Denial of Service Attacks Student Name: Aloysius Jallah Professor: Mark Merkow Name of the attack Denial of service attack (DoS): According to Week 1 TCO, denial of service attack is an attack that considerably reduces the power of the network from appropriately communicating with other networks and/or endpoint users (Merkow 2015). Hence, the end result of the attack is the incapacitation of the target network … rendering it inaccessible to its anticipated end-users through the application of flooding technique. Additionally, if the attacker understands and/or discovers that an intermediary network can give off excessive traffic capacity than the victim network can manage and/or process, the attacker uses the flooding technique to transmit an enormous batch of UDP packets headed for the victim; thus, the end result of this activity can cause flooding traffic congestion and exhaustion of the connection resources of the victim. In cunning attacks, “attacking hosts can flood packets in a burst to congest and disrupt existing TCP connections” (Kuzmanovic et al, 2005). However, for every action, there is equal and opposite reaction. As knowing denial of service (DoS) attack comes into play, software developers and system administrators also come up with the mechanisms and/or solutions to combat, reduce and prevent the potential impact of malicious criminal and/or attackers. Attack discovery and resolution dates: Denial of service (DoS) attacks can be identify...

...reflective and inquisitive minds, and are prone to the commission of errors, it is certain that nothing can be done to perfection. In spite of the fact that many discoveries, developments and inventions seem to be perfect, research has always proved that they can be improved upon. In the light of these lines, I do agree with Griffith on the statement that there is no hope of doing perfect research. The definition of the term research by the Merriam-Webster dictionary is a devoted and systematic study, investigation or examination of previously done work, with an aim of establishing or developing new inventions or conclusions. The term may also be used to imply to the revision of already existing laws, theories or experiments with a target of discovering new facts and findings. This makes the hope of doing perfect research unfeasible. The various developments and transformations, which the world has gone through since the dawn of civilization, satisfy the statement that there is no hope in doing perfect research. In this paper, I am going to support my line of reasoning by referring to two research examples. The marked improvements and developments in the fields of medicine, diagnostic and therapeutic science are vastly attributed to the doing of research. Cancer is one of life’s threatening diseases, which has enabled the doing of...
