VoIP Vulnerabilities Still Apparent by Andrew Johnson

With the use of Voice Over Internet
Protocol (VoIP) by all reports rapidly expanding, several recent cases have
exposed serious vulnerabilities with the service. However fraud is an everyday occurrence so I for one wouldn't base my decision solely on these events.

As per previous articles I have
written and various on my "About
VoIP Information" website, security vulnerabilities for VoIP do exist and
have been and continue to be seriously examined and worked through by
industry. However two recent cases
act as a reminder that all holes have
not been closed.

In Australia it has been reported
that a very public VoIP provider Engin
had it's Customer Relationship
Management (CRM) software cracked
by a hacker who publicly exposed
how to obtain details of other customer's orders in a post on the broadband site Whirlpool. Engin reportedly resolved the problem the next morning before any advantage was gained.

Engin appeared very honest and
forthright admitting the problem and
fixes that would be put in place with
blame attributed to a third party
programming consultancy responsible
for programming of the CRM.
Despite credit card details
apparently not recorded in the
area that became accessible, it
does highlight the ease at which
confidential personal information
can be accessed, not something
that is usually considered a
security problem related to VoIP.

In the very public case two arrests
have been made in early June fo
r breaking into a New York
companies network and spoofing
VoIP traffic to its service provider
. Wholesale phone connections
were then offered at discount
rates in a pseudo-service provider
manner with a resultant 100%
profit margin for the fraudsters.

TMCnet Executive Editor Rober
t Lui reported that one security
expert advised the problem could
have been easily adverted. It is
suggested that multiple security
products are required for securing
VoIP networks which to some
degree is in line with the layered
or defence in depth security
principle ie more layers of security
making it more difficult to get through.

Despite these two reported
cases and significant discussion
and reporting about a diverse
range of security considerations
and concerns, it must be
remembered that fraud is part
of everyday life and regardless
of how many checks and balances
are put in place, a determined
criminal will eventually be
successful. Such is the case
with credit cards for example,
passports and other identification
documents. The message in my
view to take away is review the
service providers performance
and virtually by the numbers game,
assuming all advisable security
precautions are adhered to, it
would be unlucky to be a victim
of hacking.

Welcome to the World of High Speed Internet by our big list of sites for sale make us an offer we can`t refuse-on one or all

Life has not been the same with the invention of the internet. It has changed the way we communicate and live our lives. High speed internet is so called, as it has a high rate of data transmission. Customers get connections at bandwidth of 256 kilobits or more. It is often called Broadband Internet access. These days the broadband implementations are up to 30 Mbit/s, which is several hundred times faster than those times when internet had become popular such as ISDN and 56 kbit/s. It even costs less than ISDN, and sometimes no more than the cost of 56 kbit/s; though the rate may differ from country to country.

Broadband connection means 56 kilobits/sec in at least one direction, and this bit rate is accepted all around the world. Broadband can also mean lower-bitrate transmission methods, as specifically no bitrate is defined by the industry. Some Internet Service Providers (ISP) take advantage of this and market lower-bitrate connections as broadband. Advanced technology in broadband can simultaneously carry and process a good amount of information at a faster rate. This gives greater connectivity or better web access, as well as higher download speeds. $ business$

DSL and Cable Modems:

Broadband connection is usually delivered through telephone lines or through cable networks. The two most popular consumer broadband technologies are DSL (Digital Subscriber Line) and cable modem; both transmitting 256 kilobits per second or more, and starting at approximately four times the speed of a modem using a standard digital telephone line. Cable modems use your cable line for access to the internet. They can be cheaper than DSL. VDSL and pushing fiber optic connections are some other newer technologies that are opening up the possibility of higher performance for streaming data, such as audio and video streams, as they would permit speeds 100 times faster than the typical DSL or cable broadband connection.

Dial-up Internet Access:

our other big package of products

In dial-up internet access, the client would have to dial up the ISP using a modem and a telephone line to establish a modem-to-modem link, which would then be routed to the Internet. This is used mostly in rural or remote areas where there are no broadband connections. This can be a time consuming process. Establishing a telephone connection and to perform handshaking before data transfers take place can take time. This way, the duration of the connection would incur costs. With modern dial-up modems the maximum possible speed is 56 kilobits/sec.

Advantages of DSL over Dial-up Connections:

* DSL is faster - DSL has the advantage when it comes to speed. DSL modems are much faster than dial-up modems. DSL provides from twice as fast speed, up to 125 times faster than a 56 kilobits/sec dial-up modem. The only limit to the speed with DSL is the speed of the Internet itself and all the different computers attached to it.

* No interference - Even though DSL uses your regular phone line, it doesn't block your phone calls. You can also take and make calls while using the Internet. You do not have to log off the Internet to make a call, whereas in dial up connection you will have to log off to use the phone.

* DSL is always connected - With DSL there is no need of a modem and you do not even need to dial up to do something online. You can check anything, browse through the web pages, check emails; your DSL connection will always be there.

* Reliable - DSL is reliable as it is not dependant on your phone line, as phone networks always experience problems; unlike a dial-up connection where you cannot connect without a phone line.

In many countries now the governments have taken an active role in spurring broadband use, and help in building communications infrastructure for public utility like in highways or airports.

Business Broadband

Business Broadband

Business broadband There are many companies who have already adopted broadband as a technology in their business today - it is now widely used to access the internet, send and receive email, network offices, provide access to web servers... the list goes on... Interestingly many of the decisions that companies have made regarding a business broadband provider were made simply on cost, locality and brand. Often overlooked are the core issues that differentiate whether your business broadband provider is high-performance or not. This article helps you ask the right questions of a business broadband provider so that you too can enjoy low contention rates, fast network access, reliable service and a friendly voice to help assist you in your business broadband related issues. The business broadband provider you use will critically impact your business and the standard of service you offer to your customers. The quality of your business broadband also has a direct effect on staff productivity and even effects morale in the business. Value in a business broadband service isn't just defined by the price - buy cheap and expect low quality, poor resilience and email only support or at best very long time to wait for telephone support. Example questions that you can ask your current business broadband supplier or prospective business broadband supplier include: * Does the business broadband provider offer a guarenteed level of service? * Does the business broadband provider focus on high-performance connectivity? * Can the provider offer added services such as voice over IP, bonded broadband and VPNs? * What is the business broadband provider's network contention policy? Be careful of any more than 5:1! * Do they have a technical support service and how fast do they answer the phone? You don't want to be on hold for long periods of time 15mins+ * You should ask your business broadband provider for client references. * What level of after-sales and technical support does the business broadband provider offer - will you be speaking to a qualified professional - will they provide you with personal dedicated support? * Do they provide you with value for money when compared to competitor services? Nathan Hill-Haimes Managed Communications is a high-performance Managed VPN Service provider - the company does not use the public internet to create VPNs as experience has shown this is where many issues regarding latency and security can occur. In addition to standard VPN services bonding of lines enables higher capacity than other service providers can offer to key VPN sites.

Internet Phones Can Save You Time and Money by Roger Overanout

Communication technology has advanced so rapidly and the entire industry has been revolutionized as a result of the advent of the Internet. Communication has become lot easier. These days you don't need to wait for many hours to get a telephone line to talk to your friends and relatives living in some other country. We can easily make Internet telephone calls using the World Wide Web. Internet telephone services are a great advantage to the people who make frequent international calls.

Internet telephone services work similar to the other communication services operated through the net. Special software such as Skype is used for setting up an internet phone connection. An internet phone service operates better with a broad band World Wide Web link. Using the Internet telephone service you can just dial up to call your friends in much the same way you use a normal telephone service. You can use the external speakers supplied with the computer and a microphone, but using a microphone headset would be more convenient because it improves the sound quality.

Many people are always looking for ways to save money. If you are one of them and trying to find different ways to cut your telephone bills, then Internet telephone service is an ideal choice for you. There are many Internet telephone service providers around the world. They set up a broadband or DSL connection with a broadband phone adapter that is plugged directly into a modem or router. You can then simply connect your existing phone to the adapter and start making calls. You can see that setting up an Internet telephone service is very easy.

The regular telephone service companies usually charge something around $20 to $30 for the basic service and this does not include any other feature such as voice mail, call waiting and 3 way calling. The internet telephone services feature all the regular services plus voice mail, call waiting, etc and they usually don't charge more than 25$ for the service, which is almost the same as your regular connection. So it is very obvious that the Internet telephone service can help you to save you a lot of bucks while giving you the opportunity to enjoy all the extra features. You can save nearly $500 per year on your telephone bill, which is a very useful amount.

The Internet telephone service has been made possible by VoIP technology. VoIP technology or the Voice Over Internet Protocol is how voices are carried over the Internet. It is similar to the other communications network. Using the VoIP technology, you can connect your digital phone to the computer and speak to your friends and relatives while you are surfing the Internet. The digital phone services can be much cheaper than the normal telephone and they also feature caller id and call forwarding. VOIP technology helps you to keep the cost of the landline telephone down. The Internet telephone service can be used in any place where an Internet connection is available. So it is really ideal for people who have to travel all over the world. You can receive and make calls from any part of the world.

However there are some drawbacks with the Internet telephones also, the Internet telephone service cannot be used in emergency cases and you may experience some delay in getting a connection. But Internet technology is continuing to develop each day and Internet phone service is also bound to develop further as a result of this.
