Computer Networks And The Internet

In the early days of computing, a hacker was primarily referred to as a computer guru, someone who is extremely technical with a high expertise in computer also known as “Expert Programmers”. Nevertheless, as technology is advancing at a face pace, hacking has adopted a completely different definition. The modern definition is someone who access a computer system primarily to steal or destroy information. Hacking has caused major harm in the realm of technology. Over the years, hackers have become much more lethal in their craft. They manage to break into complex information systems from entities such as banks, government agencies, and private businesses. Furthermore, they often manipulate their victims through social engineering in order to obtain financial benefits. Hackers hold different label such as: black hat hacker and white hat hacker in which all have their own motives.

Once, there was a boy named Tom Tapia. He was about 10, almost 11. He loved to play games like Stare_Woofs, or really any hacking game. When he grew up… he was a hacker, a black hat one. He started out as just a script kiddy, in high school, changing his grades and charging other students to change theirs. Then he grew more and more intelligent. He learned how to hack in C++, then all forms of Java, then Lua, and eventually every programming language. By the time he was 25, he was a very skilled hacker, even attempted the white house once, almost made it when the daily system reboot threw ‘em out.

The Home Depot and Target have been one of the many retail establishments cyber attack breaches that have being targeted by cyber attackers. The Home Depot was the target of a cyberattack payment card system breach where their credit card information was basically stolen on September of 2014. The attacked occurred by attackers gaining third party credentials in order to gain access to the system, after they gained access to the system they weakened the system gaining their own access privileges. After doing all the mentioned above, malware was installed quickly on Home Depot’s self-check-out system. All these steps where taking by the cyber attackers resulting in the loss of more than fifty million credit card accounts and email addresses.

1. List two advantages of wireless networking. User mobility in the workplace, and cost effective networking media for use in areas that are difficult or too costly to wire.

Many crimes have been committed using the computer as a target. Hackers have been known to target major corporations and hack into their feeds and disrupt their network flow. In 2000, on February 7, the Yahoo domain was down for three hours, due to hackers

Hacking is gaining of access to systems without any permission to access. This includes the act computer geeks looking for some fame, as well as criminals wanting to steal personal information and sell it on black markets

“Nowadays, every company with an Internet connection is a potential victim. Hackers used to focus just on high-value organizations, like financial corporations, but now the tools are so efficient and cheap that hackers can afford to attack anyone and everyone around the clock,” said Dr. Paul Judge, vice president and Chief Research Officer of Barracuda Networks, which offers IT support and data protection services.

Generally in connection based structure when two or more workstations transmit information in the same time, data gets blended up to noise and this state is known as collision. Right when the effect is seen in the workstations hold up certain amount of time and attempt to send once again. In this circumstance it can 't be picked when a workstation will get a chance to transmit. This kind of condition is known as nondeterministic protocol

"Hackers", on the other hand probably view the system more abstractly, as a resource waiting to be used at the end of a telephone line, a challenge beckoning them, calling to them irresistibly, whispering to them, "There will be no damage done and no one will be the wiser."

As the world becomes more and more reliant on computers the computer hacking industry is greatly rising. With people such as Kevin Mitnick, who is known as a "computer terrorist" (Kjochaiche 1), computerized information isn't safe any more. Kevin is known as "the most high-profiled computer criminal and responsible for more havoc in the computer world today."(1) He considered this a fun and easy task. He got caught and thrown into prison, but once he got out nothing changed. Kevin stated that as long as the technology is there it just calls to people to break into it. Computer hackers usually start off young, thinking that it is nothing but a little harmless fun. But as they get older, they realize it has turned into

Threats against big companies and people across the world isn’t a trending topic. A lack of protection from within the platforms can create internal, external, and political problems for people and business companies. Internally, hackers try to compromise computers and gather sensitive information from the inside as if it was their private property. Externally, hackers gather information for their own personal gain and to pose a great threat from outside of the business or person’s home because they can find access into the system a lot easier with new advanced technology. Over time, computer hacking has grown into something that is essentially a worldwide problem in countries like North Korea, Russia, the United States, and China that is. Overall, some these countries are trying to eliminate and capture hackers and produce a stronger more secure based program for all of the computer platforms. The literature points out that the only way of fixing the problem with hackers is to invest much more money into producing a more secure security system for all platforms that is basically impossible to decode or enter the program.

Also criminals can use computers to communicate and store data. These criminals involved in these illegal activities are called hackers.

Local area networks (LANs). DEFINITION The concept of local area networks (LANs) is not new. It represents a logical development of computer technology. With the advent of microcomputers in the 1980s many office workers began bringing their own disks into work, compromising data integrity.

Stealing valuable data: Hackers steal data stored in the internet worth millions of dollars. With access to such valuable data, they can then generate revenue, promote terrorism.
