Since the organization is lodging understudy individual data and also managerial resources and organization data, it is fundamental that the framework is still utilitarian, solid, and secure. PC systems have considered this innovation and are presently separated of verging on each business. The building housing some offices, classrooms, a library, and computer labs has two choices with regards to setting up a system. They can utilize a totally wired system, which utilizes organizing link to associate PCs, or they can utilize a remote system, which utilizes radio frequencies to interface PC. Remote systems or commonly called wireless network have permitted associations to wind up more versatile; in this way, associations are currently utilizing a blend of both wired and remote systems. They fundamental equipment format for the two sorts of systems are genuinely comparative yet for an association to go remote it requires a couple of more equipment parts. In spite of the convenience nature of computer system, they do open the association up to security and protection dangers. In the event that an organization is confronted with a security they are ways that they can alter and forestall future security dangers.

When a computer is infected with a botnet your computer can perform tasks over the internet while you have no clue its happening. Normally criminals infect a large number of computers forming a network or a botnet. Botnets send out spam emails to spread viruses attack other computers and to commit other kind of crime and fraud. Some botnets can be large some can be small but size does not matter either way damage will be done regardless. Some of the most popular botnets are Conficker which never has activated to cause significant damage, but that don’t exactly means the threat is gone for it still remains very active. Another one is called Zeus. Zeus is a large botnet and has much detection mainly because individuals can configure it to use a different command. Zeus is mainly is configured to steal information such as banking credentials and send it to its attacker. Waledac works thru a peer-peer network and it can load malicious software, and proxy HTTP content to host malicious websites. Bredolab main focus is on downloading Scareware, fake anti-virus programs, and Ransonware. Their plan is to infect many computers with these programs and hope the victims purchase these programs and make some profit. Pushdo/Cutwail is two different botnets that use each other.

...Cyber Security Student: Maurice Jones Class ISSC461: IT Security: Countermeasures Instructor: Professor Christopher Weppler Date: 2 August 2013 Introduction “In a future conflict, an adversary unable to match our military supremacy on the battlefield might seek to exploit our computer vulnerabilities here at home (President Barack Obama, 2012).” Technology has changed the total lifestyle of people around the world. Here in the United Stated, society’s daily lives revolve around social interaction, economic stability, job security and information dominance. Information Dominance is “the degree of information superiority that allows the possessor to use information systems and capabilities to achieve an operational advantage in a conflict or to control the situation in operations other than war while denying those capabilities to the adversary (US Cyber Command, 2012).” Corporations as well as many of the world’s governments have risen and fallen due to their degree of Information Dominance and Information Security. Cyber-attacks have increased exponentially within the last 10 years. Battlefield lines that were once drawn in the sand no longer exist. Cyber-attacks can occur from any location in the world and at any time. A Cyber-terrorist has the ability to use current communication infrastructure to launch an attack that could cripple a nation. In 2012, Defense Secretary, Leon Panetta spoke at the Business Executives for National Security (BENS) summit....

...Challenges to Criminal Law Making in the New Global Information Society: A Critical Comparative Study of the Adequacies of Computer-Related Criminal Legislation in the United States, the United Kingdom and Singapore Warren B. Chik* Introduction Computer and Internet usage is on the rise due to lower costs of computer ownership and connectivity as well as faster and easier accessibility. As it is another mode of commercial and personal transaction and one that is heavily dependent on interaction through computers and automatic agents rather than face-to-face meetings, which increases distance and allows anonymity, it is another avenue for crimes to perpetuate. “Computer Crime” encompasses crimes committed against the computer, the materials contained therein such as software and data, and its uses as a processing tool. These include hacking, denial of service attacks, unauthorized use of services and cyber vandalism. “Cyber Crime” describes criminal activities committed through the use of electronic communications media. One of the greatest concerns is with regard to cyber-fraud and identity theft through such methods as phishing, pharming, spoofing and through the abuse of online surveillance technology. There are also many other forms of criminal behaviour perpetrated through the use of information technology such as harassment, defamation, pornography, cyber terrorism, industrial espionage and some regulatory offences.

...Chapter I Introduction A. Background of the Study A browser is software application that provides a way to look at and interact with all the information on the World Wide Web (Goertz, 2001). It uses HTTP to submit requests of web servers over the Internet on behalf of the browser user. Web browser is use for retrieving and presenting information resources identified by a Uniform Resource Identifier (URI) that may be video, image, web page, or other kinds of content. It can also be used to access information provided by web servers in private networks or files in file systems. There has been a virtual explosion of browsers which are designed according to their operating system and others, target specific users such as those majoring on social networking. There are also clones of established browsers such as Firefox and Google Chrome which seek to improve on the original by being “leaner” of offering different features (Anonymous, 2011). According to Bowler (2009) the browser world have spent time focusing on delivering their product to multiple OS. This helps them build many of the browsers such as Mozilla Firefox, Google Chrome, Opera, Internet Explorer and Safari. Mozilla started from scratch — Firefox was the result. And now users have no shortage of browsers to choose from, partly due to the work of the Mozilla foundation. the first full point release of Mozilla’s popular open-source Web browser in nearly three years, combines user-interface, performance and Web-standards...

In the early 1980s, Steve Wozniak left the company and Steve Jobs hired John Sculley as the President of the company. After facing many failures, Apple launched its Macintosh computers for house hold users. In mid 1980s, Steve Jobs had to leave the company because of his controversial relations with the president. At that time John Sculley rejected the offer of Microsoft‘s CEO, Bill Gates to license the Macintosh operating system to Microsoft. After this refusal, Gates developed DOS operating system and in late 1980s, the competition between DOS and Macintosh decreased Apple's sale, workforce and resignation of John Sculley. So, Apple's current CEO planned to purchase Next Step operating system of Jobs in order to improve the Macintosh operating system. In late 90s Jobs again became the CEO of the company and be started surprising relations with Microsoft by developing a Macintosh version of office software. Apple also took cost saving measures like streamlining the product line, production of printers. Steve Jobs brought Apples' focus on two concepts of consumer series with the prefix “I” for internet like iMac, iBook laptop and professional with prefix “power” such as PowerMac desktop and PowerBook...

A SWOT analysis not only can help an organization realize it strengths, weaknesses, opportunities, and threats it can also help the organization capitalize on the weaknesses that may exist with other organizations. Introduction Apple Inc. was founded 1976 and was the brain child of Steven Jobs and Steven Wozniak. Although the organization was actually born on April Fool’s Day many will agree that Jobs and Wozniak’s vision for the future of computers was much bigger than a foolish dream or prank. Wozniak had a love for developing computers and while working for Hewlett-Packard he developed what would become the first Apple Computer (Apple, n.d.). It was Jobs vision of the future with computers that pushed Wozniak to realize his dream of selling his first very graphic computer. Apple struggled its first year trying to convince the public to purchase its newly graphic designed computer. It was not until 1977 when Apple...
