Cable and Internet Networks
In most cases cable or DSL companies such as Comcast or DirectPC are just a single type of Internet connection company. But sometimes companies acquire these one-connection companies to make their companies bigger and better such as AOL buying Time Warner. As these companies get bigger and start to offer more types of connections they also start to have more security conflicts. AOL’s software for its dial up connection has a firewall built in to it, the firewall protects it users from hackers and unwanted programs from running. And the software works almost perfectly for keeping unwanted people or programs out, but the only catch is you have use their software. Road Runner, which is now part of AOL, is a cable company, which only provides high-speed Internet access, not full proof security. This problem leaves you open for hackers that are randomly barraging Internet connected PC’s with “pings” or “port scans”, probing to find unprotected PCs. Once found, a hacker can compromise your PC with a dangerous Internet threat such as a Trojan horse, spyware or even a malicious worm (Zone Labs).
Since AOL doesn’t provide any type of firewall or hacker protection while you have a cable connection with them they do suggest certain types of firewall software to buy. For single end users they suggest you use firewall software like Norton’s Personal Firewall, which costs around $49.95, or NetBarrier 2.0 if you own a Macintosh. Both of these software packages include basic features for a single end user, for instance the ability to delete your cookies and the ability to set up filters or rules to a computer. For network users AOL suggest that you use firewall software such as ZoneAlarm Pro 3.0 which costs $49.95 for a one-user license and goes up from there. ZoneAlarm Pro 3.0 not only provides cookie control, pop-up ad control but also provides email protection and it can suspend 46 different file types. Unlike other personal firewalls, ZoneAlarm Pro includes Program Control to protect against known and unknown threats. With ZoneAlarm Pro, you can control the ability to specify which programs are trusted to access the Internet, by monitoring all outbound traffic. You can also block and make your computer invisible on the internet-“if you can’t be seen, you can’t be hacked” (Zone Labs). Another type of software that they sugge...

Hacking, with the intent to steal or deface, is so feared in the corporate world that companies have spent $1.8 billion this year alone on computer network security products and services (Home Hackers 1). Cracking of home computers has been rare, but it is always a growing concern. Any machine connected to the Internet is potentially vulnerable, but the best targets are those with high-speed, "always on" connectors, such as cable modems or digital subscriber lines. Systems with high-speed connections are typically targeted because they are the simplest to track down. People have to realize that hacking is not a prank or a game, especially when hackers are hitting such spots as the White House site, the FBI site and the Senate site. The fines and jail time for these hackers are not very funny either. Arrests are being made and punishments can be up to life in prison and thousands, and in some cases millions of dollars in fines.
In the world today, computers are used in every field. Be it a major space exploration or a small chore like cleaning our room. The use of computers has made our lives easier but at the same time a computer failure can make our lives miserable too. We trust computers more than we trust anything else these days. We use computers to communicate, share personal information, buy goods online, etc. We also trust computers with our safety. Starting from house alarm systems and other safety devices we have now moved on to using computers to Test Car Crashes.
Things of this nature can happen and have happened in the past. Back in the old days you had mechanical switches doing crossbars, things of that nature. Today all telephone switches are computerized, they're everywhere. With a computer switch, if you take the first word "computer" that's exactly what it is, a switch being operated by a computer. The computer is connected to a modem, so are you and all the hackers, therefore you too can run the switches.
Privacy and security issues have become one of the top concerns among computer users in today’s market. It has become a game of survival of the fittest in protection of your security. The only true way to defend yourself is knowledge. You should prepare your self against hackers, spammers and potential system crashing viruses and web bugs. Lets focus on how you can protect yourselves from the would be thieves.
The computer will start to perform well and there will be no more
The protection of your network requires a level of network security. If you do not have security on your network, then you are capable of being hacked or receiving malware, spy, virus, and lots more. There are many programs or applications that can help detect and prevent strange activities on your computer, but there is also ways that you can help prevent anything from happening. Creating a password for your network is a good start toward protection of your computer. Try to make the password something only you would know, and maybe throw some numbers in there as well to maximize protection. It is good to know who all is on your network and internet; because if someone were to log on to your internet from a distance, they could plant viruses and other things into your files on the network. Quite a bit of problems occur in network when file sharing takes place in a work place to copy or manage files. Most of the time when this happens, no one sets the security setting up themselves,...
Prior to 1995, AOL was very successful in the commercial online industry relative to its competitors CompuServe and Prodigy primarily because of its pricing rate structure which was the easiest for customers to understand and plan for ahead of time. CompuServe and Prodigy offered the same pricing as AOL for its standard service, but, charged additional fees for premium services and downloading which made it more difficult for customers to anticipate their monthly spending.
The Internet boom of the 1990’s gave rise to the popularity of America Online AOL and Time Warner saw themselves at a crossroads where old and new media would become one. The histories of both AOL and Time Warner are extensive and have not always been successful. Time Warner itself was created by two mega-mergers. The first merger was in 1989 between Time Inc., publisher of many magazines such as Time Magazine, and Warner Communications. Both companies have histories stretching as far back as 75 years or so. In 1996, this company merged with Turner Broadcasting, which brought CNN with its founder Ted Turner. These two mergers created a company ready to lead in any form of media. The company launched the HBO television network. Time Warner, headquartered in New York, had $27.3 billion in revenues in 1999 and a market value of $112.6 billion. On the other side of the merger there is new media giant AOL, today the biggest, richest, and most successful internet company in the world. It was founded in 1985 as Quantum Computer Services and by 1994, after changing its name, had a million subscribers. In its early years, it almost fell because of the problems associated with introducing unlimited access for a fixed monthly fee. As its number of users increased, so did its capacity problems, which made many customers angry because they could not get a connection. The problem was solved when AOL made a deal with MCI WorldCom, which led merge with its rival CompuServe.

The Internet is a fun little playground and at the same time a hostile environment. Like any other society, it's plagued with the kind of people who enjoy the electronic equivalent of writing on other people's walls with spray paint, tearing off their mailboxes, or just sitting in the street blowing their car horns. Some people get real work done over the Internet, and some must protect sensitive or proprietary data. Usually, a firewall's purpose is to keep the intruders out of your network while letting you do your job.
... to get user data back (“Ransomware”). This means that criminal is using a computer by locking your computer by passing your permission on the computer. This makes it possible to make millions of dollars by making viruses and scams in less than one hour (ComputerCareClnc). In the computer world we will never find the true answer.
Digital Subscriber Line new technology that takes advantage of standard copper telephone line to provide secure, reliable, high-speed Internet access. DSL refers to the family of digital subscriber line technologies, such as ADSL, HDSL, and RADSL. Connection speed for DSL ranges from 1.44 Mbps to 512 Kbps downstream and around 128 Kbps upstream. Unlike traditional connections DSL such as analog modems and IDSN, DSL deliver continuous “always on” access. That means multimedia-rich websites, e-mail, and other online applications are available anytime. DSL makes it possible for you to remain online even while you’re talking on the telephone-without jeopardizing the quality of either connection. DSL is available in a spectrum of speeds. Some are best home use, while others are designed to accommodate rigorous business demands. Whether for business or the home, DSL, offers unsurpassed price/performance value compared to other online options. There are the five facts that one should know about DSL. It is remarkably fast. With DSL service, you can benefit from Internet speeds that are up to 12 minutes faster than a typical ISDN connection and 50 times faster than traditional 28.8 Kbps modems. This means that in the 12 seconds it takes to read this information, you could have downloaded a 2 megabyte presentation file or web photograph. It would take 10 more minutes (600 more seconds!) to download the same with a traditional 28.8 Kbps. It’s highly reliable. One can depend on DSL because its proven technology takes full advantage of the existing telecommunications infrastructure. It’s inherently secure. DSL network provides a dedicated Internet connection via private telephone wires, you can bypass dial-up intruders or shared network hackers. Unlike traditional dial-upp modems or cable modems. DSL protects your valuable data with the most secure connection available. It’s surprising affordable. DSL is widely recognized as the most cost-effective connectivity solution for small buisness. DSL delivers industrial- strength like speed to multiple users at only 25% of typical TI costs. There is no better price option available. DSL is also an exceptional value for home users. At about $2 a day for services that meets the needs of most people. The connection is always on. It’s ready to run every minute of the day. There’s no more logging on and off. No more busy signals or disconnects. This gives you the freedom to focus on what you want to accomplish on line rather than focusing on trying to get connected.
...ntial information from a user. Luckily, there are reliable ways of defending against them. The most reliable way is to install strong security software that has the capacity to defend against the multifaceted forms of threats. Avoiding P2P file sharing sites and scanning email attachments before downloading them are also a surefire way of protecting a computer against malware threats. Basic acts like using an updated browser and allowing Windows updates to install and update themselves are also necessary to keep a machine safe. Furthermore, checking validity of individual website addresses and installing authenticated software can also help a computer user remain safe from potential data theft and possible damage of useful programs. It may also pay good dividends to backup files. In case of a lethal malware attack, backed-up files can always be recovered easily.
Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
Introduction: This is a 21th century, technology is the most important and improved thing of the human life. It makes life easier and faster. Development of faster sophisticated technology we have better and fast life. So all we are connect each other by computer network. There are two different way of network: Wired and wireless. Now day we can found network almost everywhere. Home, business, public place, Airport, Planes, hospitals, school, train everywhere we can found networking. Therefore, almost every sector of the economy that has affected by wired and wireless technology. Wired network and wireless protect both has security, But in general wireless network is less secure than wired networks. For proper security AP (access point) and its antenna should be right position. Also add a wireless access point or use a wireless router we can connect to network wirelessly. AS we using more and more of devices (smart phones, tablet and computers) rely on wireless networking, we have to improve our network security too.
