Internet

If you use your computer on the internet, you need (at minimum) anti virus software. The problem of computer security is the number one problem in today’s networks and Internet engineering. As hackers use different means to crack the security systems it often happens to be impossible to resist and computer security system fail.

Computer Security on the internet is vital for home and business use as there are increasingly hostile environments when users surf the net. It is very important for users to be educated on the dangers they may face while on the internet. Your computer connected to the internet is similar to your house in many ways. Users search on the internet for free computer security software which they dump into their computers and hope for the best.

The Internet is a wonderful place. Anyone with an Internet connection can stay in touch with family and friends via email. Computer security is growing rapidly by the minute and the only one who has control over their files of information is the user. It is strongly suggested that users equip their pc with an armed fire wall for vital protection.

An advice is to use Microsoft Windows Update to keep your operating system and Internet Explorer patched. Other advice could be to only conduct Internet transactions that have secured processing. for more detail go to:www.fire-itup.comEven if you have a computer connected to the Internet only to play the latest games or to send email to friends and family, your computer could be a target.

Although confidentiality, integrity and authenticity are the most important things when it comes to computer security in general, for everyday internet users, privacy is the most important one, because many people think that they have nothing to hide or the information they give doesn’t seem sensitive when they register with an internet service/site.

Spy ware

An avenue for Spy ware to infect your machine is through popular Peer-to-Peer File sharing software such as Kazan. Extreme spy ware like Root kits and other advanced spy ware have fundamentally changed the playing field in today’s computer security.

While it may seem to be common sense, many of the most widely-spread attacks have involved spy ware and email attachment worms. Often these packages come as “suites” including a firewall and Spy ware scanner. They scan and destroy spy ware as it’s found in the user’s computer.

Regardless of the type of spy ware, it can slow your computer to a crawl and needs to be removed from your computer. Spy ware occurs when certain websites run programs in the back ground of your computer while gleaning information from it. There is now a bill in the US Congress to make Spy ware illegal.

Even the U.S. Federal Trade Commission (FTC for short), which is a governmental bureau that is designed to assist customers, had to publish a press launch stating that customers, including company and banking executives, might be victims of a fake e-mail supposedly sent by the FTC. The fake document was actually sent by a third party trying to fool users into installing malicious software onto their computers.

There is little doubt that adware, malware, and nasty virus assaults make any pc with an internet connection open to attack. But, not all Web safety breaches are immediately obvious. In point of fact, most people are usually oblivious of the fact that their seemingly hassle-free computing is at serious risk from criminal elements.

Now that you understand the scale of the problem, here are seven pointers to assist you to navigate the world-wide-web in safety:

1. Shield your private information as it is important to prevent identity theft. For instance, when making a purchase on an ecommerce web site, be sure that the page where you enter your personal data is safe, as designated by “https” in the URL shown in the browser address bar.

2. Be mindful of the possibilities before you click on a link. For instance, many cyber-criminals impersonate reputable companies, or send out a “phishing” e-mail that asks you to click on a link. Check out on-line retailers and by no means click on emailed hyperlinks unless you are sure of the source. Usually you can just hover over an email link to see the actual internet address it goes to, but not always. If it looks suspicious, then don’t click on it as it will send you to a website set up to steal your details.

3. Keep your antivirus and firewall software up to date. The trouble is, hackers and others who engage in cyber-crime appear to always be one jump ahead of the curve. In the case that your pc protection is out-of-date, you are vulnerable.

4. Use an internet browser and computer OS that has good safety features. Be certain your browser settings offer you optimal privacy and safety, and be certain that you update your operating system often to make the most of security patches.

5. Use secure passwords at all times. For example, create a single password for every site you go to, and maintain them in a secure place. Use letters, numbers and other symbol mixtures in an effort to circumvent automated password detection programs.

6. It’s vital to perform frequent backups. If your computer does suffer a virus or a worm, your most importantinformation may be lost. Make sure that you frequently make a backup of any essential records and store them in a secure place.

7. Be prepared for all contingencies. If something does go wrong, such as your pc being hacked or infected with a virus, or should you unintentionally reveal private info, know what steps to take to remedy the situation and prevent additional problems.

Protecting your financial and personal data from all of the threats in the on-line world can seem like an impossible task. Fortunately there are many software vendors who make it their business to supply people and companies cutting-edge pc security software. They will help to keep your computer secure from the many threats which stem from the modern bandits of our time, who infest the internet and make safe computing more and more difficult.

Recently, my neighbor asked me about how to call international long distance with no-minute charge. He also was interested in learning how to lower his home phone bill. I told him about a phone system called VoIP that would benefit his interest. This article is a brief information to introduce VoIP to you.

First, do you know how many people are using VoIP services? Here are interesting numbers… In 2007 there were almost 65 million worldwide voip subscribers. In the USA, over 16 million US VoIP subscribers, with continue to grow 6-8 million new subscribers every year, about 24 million US VoIP subscribers expected by 2008. By 2010 , US VoIP Subscribers will reach 44 millions, and the number of worldwide subscribers is predicted to rise to over 197 millions.

So what is VoIP – VoIP is standing for ” Voice over Internet Protocol “. VoIP also is referred to as Internet Telephony, IP Telephony, or Voice over the Internet, VoIP Telephone, Broadband Telephony, Broadband Phone, Voice over Broadband, or simply Internet Phone.

Voice over Internet Protocol (VoIP) is a protocol optimized for the transmission of voice hrough the Internet or other switched networks. It’s described as the transmission of voice traffic over IP-based networks, a unique technology that allows us to make calls using a broadband Internet connection ( through broadband modem ) instead of a regular (analog) phone line. At first, the Internet Protocol (IP) was originally designed for data networking systems. Later, with its success in data networking field and the explosion of Internet Era, the IP has been developed in voice networking and nowadays it is bringing us the most profit in this field. VoIP has become more and more popular because of the cost advantages to consumers compares to traditional telephone networks.

A brief explanation on how does VOIP work? – The traditional phone system is using analog phone signals to deliver and receive calls, with VoIP system, it’s using digital signals that can be sent over the Internet. If you have quality Internet connection – DSL (digital subscriber line), described as High Speed Internet Service which makes fast Internet connection ) you can get phone service delivered through your Internet connection instead of from your local phone company. In basics, here is how system works:

PC to PC: Computer connects to Broadband Modem connects to Internet connects to Broadband Modem connects to Computer

PC to Phone: Computer connects to Broadband Modem connects to Internet connects to Telephone Network connects to Telephone

Phone to Phone ( using Router ): Telephone connects to Phone Adaptor connects to Router connects to Broadband Modem connects to Internet connects to Telephone Network connects to Telephone

Benefits of using VoIP: There are two major reasons to use VoIP: Low Cost and More Profits

Low Cost: Phone services via VoIP costs less than equivalent services from analog systems. With the traditional analog phone services, users pay a flat monthly fee for the service, and pay other fee for long distance call service plus per-minute charge. With VoIP, the users who already have High Speed Internet service (DSL), can take advantage by using VoIP over this service – Many VoIP Service Providers allow you enjoy unlimited in-network calling – it means you can call any other in-network customer without charge. Other companies allow you to call any number, including local, long distance, mobile, and international numbers. For International calling, the users who using VoIP can get big savings with lower rates. Depends on each VoIP service offer, you can enjoy unlimited calling worldwide to many destinations for a flat monthly fee with no minute charge or low rates.

More Profits – Compares to analog phone networks, VoIP has more advantage functions. You can make calls from your personal computer to other’s computer or other’s regular phone, or you can make calls directly from your regular phone to other’s regular phone. Besides, The digital signals let you enjoy high quality voice and many advantage services such as Voice Mail, Caller ID, 3-Way Calling, Call Waiting, Speed Dial, Repeat Dial, Do Not Disturb, Call Forwarding, Emergency 911 Service, Online Account Management, Virtual Calling Card, access the service to your cell phone…

Further more, Incoming phone calls are automatically routed to your VoIP phone where ever you plug it into the network, so you can take your VoIP phone with you on a trip, around the world – anywhere you can connect it to the High Speed Internet, you can call and receive your incoming calls anytime. The VoIP Router can be set up anywhere with High Speed Internet, it provides you the advantage of savings. For example, a VoIP provider allows you get the US number and connect the router outside of the US. So when you call to that number, just like you call locals, and the person who is in other country calls you by using this service ( connected through router ) just pay a very small charge per minute, or sometimes it’s free.

Many consumers still lack the information about VoIP phones and Internet phone service plans they need to make a shift to VoIP. Many will wait until there is a critical mass effect. That’s when a large number of people will shift to VoIP and when VoIP lingo is a common part of people’s vocabulary. Since VoIP operates seamlessly with current phone systems, it’s not a technology that jumps out at people.

Not long ago Google was an obscure web search engine that had little consumer usage. But then Google started to make noise, and it did so with the help of students and web marketers who believed it had something to offer. Now, the word Google is used as a verb and people wonder how they ever got along with its info finding magic. VoIP is starting the same way but still hasn’t found a way to move into mainstream consumer lifestyles. Rest assured though, that VoIP companies are targeting a variety of consumer demographic groups such as teens with cell phones, migrating people to Europe and North America who want to stay in close contact with their relatives back home, and businesses with multiple distant office locations who need inter-office phone communications. For regular home phone users, the value proposition they’re receiving is not as compelling. That will change too as VoIP companies research ways to make that home phone service more valuable to consumers, or to make it unnecessary to keep it.

That critical mass event happens when users believe they have a clear cost savings advantage to make the switch from using their regular telephone service to a VoIP phone service. Being able to dump the home phone would certainly provide a reduction in monthly bills, but consumers aren’t dropping their expensive land lines, even though they may have cable television and cell phone bills to boot. In telecommunications, it seems consumers are over-serviced, and a solution is needed. Internet telephony has that potential to eliminate some of the redundant services, but it hasn’t matured to the point where it can shape the phone services market by itself.

Phone companies in defending themselves, put a fair amount of effort into discussing the possible downside of VoIP and some have even put restrictions on VoIP transmissions to try to thwart VoIP service providers. Old stories of lost calls, garbled voice quality, non functional 911 assistance, and loss of privacy don’t carry much weight anymore though. Quality and technical issues are almost all resolved and the services continue to improve. So, if it’s not technical issues that are preventing widespread VoIP adoption, then what is the problem?

Need to Drop the Land Line

Many consumers won’t adopt a VoIP service until they can drop their current phone company land line completely. Despite the desire to do so, many appear to be resisting eliminating their dependence on the old lines. Most don’t want to be paying for two phone services at the same time, yet they do. A billion people on the planet have cell phones now, so that means there are a lot of phone lines that aren’t necessary, or that are too expensive given the value they offer. As long as phone companies can make customer’s land lines indispensable, or encourage them to stay put, they know their customers won’t switch to VoIP plans. So that leaves many consumers with more than one phone, a home phone and a mobile phone, and it’s costing them a lot of money.

For those who don’t make frequent long distance phone calls, the cost savings from VoIP service plans aren’t compelling enough. However, when you add the cost of the call and line features that phone companies add onto the monthly phone bill, the scenario changes. Call features such as caller ID, call blocking, call waiting, and voice mail, are free with VoIP plans. If these aren’t enough to entice consumers, VoIP companies will certainly look to sweeten the offer. Internet protocol communications are improving all the time and there will be more to offer the consumer such as; services via PDA’s, Blackberries, and IP hard phones connected to WiFi and WiMax services.

Internet Phoning Drawbacks

When VoIP users make a call to another VoIP user, the call is essentially free. However, not everyone has a VoIP-based phone to receive VoIP calls. Many only have their land line or in some cases, a cell phone. That means the call has to go from the Internet into the PSTN or public switched phone system in the destination state or country. This is where the cost of a call shows up. Usually the cost is low for terminating the call to the end user. If the caller is making a long distance call however, this nominal cost is a small sacrifice compared to what they’ll be paying on their traditional home phone service.

High speed DSL customers must have their basic phone service, so as long as they need the high speed Internet connection, they might not switch to VoIP. For cable subscribers, a land line is not needed and VoIP works very well with Cable Internet service. For cable subscribers, the land-based home phone really isn’t needed so the jump to VoIP should be an easy one for cable subscribers. If they aren’t making the leap to VoIP, it might indicate a lack of confidence in cable networks. Most people still have trouble comprehending that a voice telephone call can go through the cable company, or that it will be reliable. Cable companies have come a long way with their technology and networks and are more than capable of providing top notch phone services.

With better education of telecommunications consumers and the presentation of a solid value proposition that offers more than a little cost savings, VoIP will grow steadily. For those with international calling needs, VoIP is already the solution they’re looking for. For small businesses with lots of long distance calling, the savings are even more pronounced. What’s needed is more consumer education. With that, many will finally wean themselves from their dependence on that old analog-based land line telephone and launch into an era of cheap digital phone calls. That day is coming soon as the major phone companies are under increasing pressure to raise the price of local phone service in the face of a major shift to VoIP transmission. Critical mass will occur when price plus features create a force that overcomes consumer’s inertia.

Much of the hype has been around residential VoIP, rather than business VoIP communications. It is crucial to understand that major differences exist between residential and business grade VoIP solutions. Relying on a residential grade VoIP service can have disastrous effects for a business, including loss of sound quality in phone calls and down time where your business’ ability to communicate may be cut off entirely. The integration of a business grade VoIP solution has many cost and efficiency benefits for Australian Small to Medium Businesses (SMBs).

The most obvious advantages of a business-grade VoIP solution are the reductions in call and line rental costs, however, there are many other significant business advantages for SMBs of all sizes to realise:

* Increased productivity by integrating VoIP with the computer desktop and allowing features such as Click2Dial from Outlook

* Increased business metric capabilities from detailed reporting on inbound and outbound call patterns

* Vastly improved and centralised personal attendant and reception capabilities allowing visibility of all staff extensions in a consolidated view, simplifying transfers to extensions and voicemail

* Awareness of an individual’s location as ‘available’, ‘busy’ or ‘out of the office until 2pm’

* Increased efficiency from converging the voice and data networks (operating both voice and data on the one network)

To decide how best to integrate VoIP with your existing voice and data infrastructure you must have a clear understanding of your business drivers and the results you wish to achieve.

VoIP Gateways

Ideal times to consider the introduction of a VoIP solution are during an office relocation, or during times of high growth. An excellent entry level solution for businesses who wish to experience the benefits provided by VoIP is to connect their phone system to PSTN via a VoIP gateway device. A VoIP gateway device is a simple piece of hardware that allows the basic integration of VoIP with a traditional phone system, most often without having to physically change any configuration.

Pacific Internet’s VoIP gateway is connected via a business-grade broadband service and will send calls destined for external locations (whether local, national, mobiles, international or another VoIP service) across the VoIP network and into the traditional phone line at the destination point. It is Pacific Internet that maintains connectivity to the traditional phone line. This scenario allows for the seamless integration between the two networks (PSTN and VoIP) and a traditional phone system to co-exist with a VoIP solution. The advantage of a gradual migration to a total VoIP solution is that it allows you to immediately appreciate some of the benefits of VoIP, without the upfront cost of replacing your entire existing voice infrastructure.

Connecting to Traditional Voice Networks via VoIP

A number of scenarios are available to connect your phone system to the traditional PSTN via VoIP, the most common of which are:

* Full replacement of traditional analogue or digital lines for all inbound and outbound calls, providing for standard geographic Direct Inward Dial (DID) numbers to be allocated to the VoIP service, for example, 02 9999 9999 for Sydney, 07 3333 3333 for Brisbane, 02 4900 0000 for Newcastle

* Partial replacement of traditional analogue or digital lines for all outbound calls

* Installation of additional VoIP lines to sustain call overflow during unexpected or regular peaks in outbound calls traffic

* Additional lines for calling only specific, designated prefixes. For example, making all outbound calls to mobiles via VoIP.

Each of these scenarios can be configured to either work automatically or to require manual user selection with most phone systems. For example, if VoIP is being installed solely to make all outbound calls to mobiles then the phone system can be set-up via Least Cost Routing (LCR) to automatically use a VoIP line when an individual calls a mobile.

An important consideration when integrating your traditional telephone system with VoIP is to very clearly understand current calling behaviour. For consideration are items such as:

* How many simultaneous inbound calls does the business receive?

* How many simultaneous outbound calls does the business make?

* How many spare PSTN ports (or trunk ports) does the telephone system have?

* Are the spare PSTN ports for analogue lines or for digital (ISDN) lines?

* If there are currently insufficient spare PSTN ports, can the phone system be cost-effectively upgraded with additional cards to provide sufficient port capacity?

Once you have a clear understanding of your current call behaviour and phone system, you can accurately determine how many VoIP lines are required and the resulting demands this will place on business-grade broadband service. You must consider bandwidth requirements, segregation of voice from data, and Quality of Service (QoS).

As your VoIP provider, Pacific Internet, can make qualified recommendations on the best configuration to achieve your desired business benefits. Integrating VoIP with an existing business data network and phone system takes a significant amount of careful planning and it is crucial that this step not be overlooked, however, it is an ideal way to test a VoIP solution and immediately start to appreciate some of the cost and efficiency benefits that VoIP can provide.
