Virtual Private Network in Banking

How does Virtual Private Network service work in banking?
Whenever you use the internet through an Internet Service Provider (ISP) or at another site, your computer is given an address on that provider's network. While you can reach your bank from the Internet, you will normally be denied access to services that are restricted to bank network addresses because your computer is using an address from an external network.

But, if you are on the internet, you can still connect to the Bank’s VPN service, in two ways. From a web browser or with a software VPN client. A VPN need not have explicit security features, such as authentication or content encryption. Virtual Private Network setup, can be used to separate traffic of different user communities over an underlying network with strong security features.

Seek secured private connectivity across public IP networks!

Extends geographical connectivity
Improves productivity
Improves security
Reduce transit time and transportation costs for remote users
Reduce operational costs versus traditional WAN
Simplify network topology
Provides global networking opportunities
Provides broadband networking compatibility
Provides faster ROI than traditional WAN
Provides telecommuter support

VPN are categorised into two types:
• Remote access VPN
• Site to site VPN

What is site to site Virtual Private Network in banking?
Such Site to site VPN allows you to have a secured connection between locations across the open internet. With the help if site to site VPN your bank can save a great deal of money, as you can use cheaper means always – on connections such as domestic broadband rather than expensive leased lines between sites.

What about Remote access VPN?
Remote access VPN also known as Virtual Private Dial up(VPDN) is used by banks who have staff regularly working in locations outside the office. You can connect into the office network over dial up phone/isdn lines or over broadband from anywhere.

Virtual Private Network banking uses advanced encryption and tunneling to permit computers to establish secure, end-to-end, private network connections over insecure networks, such as the Internet or wireless networks. VPN services can impact your overall computing and network performance. VPNs exist to protect traffic on public data networks like the Internet. VPN Services will work with other ISP dialup services too. Try your online route for your VPN.

Personal Wireless with Bluetooth

If you already have a wireless network for your computers, you may be very interested in what's coming next. Would you like it if your PDA, your mobile phone, your mp3 player and almost everything else you connect to your computer could be wireless too? It's already a reality...

Personal Area Network.

Using wireless networking with your personal gadgets is often called PAN, which stands for Personal Area Network. The idea is that, in the future, we'll all have laptop computers with their batteries charged and no more need to connect any wires to them at all -- you just place your Bluetooth device near the computer, and the computer sees it and can use it straightaway.

Bluetooth has been around and in-use since 1999, and it's only getting more popular. It was designed to be secure, low cost, and easy to use from day one.

There are two classes of Bluetooth that are in popular use: class 1 and class 2. Class 2 is the most common and cheaper standard, allowing you to use a device that is up to 10 metres (32 feet) away. Class 1 is rarer, but you can still find devices that use it easily enough, and it has ten times the range: 100 metres or 320 feet.

How Does It Work?

Bluetooth is more flexible than 802.11 wireless networking, in exchange for the shorter range. Essentially, a Bluetooth-enabled computer has one Bluetooth receiver installed in it, and this receiver can then be used with up to 7 nearby Bluetooth devices. On the other end, wireless devices do not need to have Bluetooth installed if they support it -- it is already integrated.

Like 802.11, Bluetooth works by using radio signals to create bandwidth. It is not, though, the same thing as an old-style wireless mouse or keyboard, which required a receiver to be plugged into one of your computers' ports, and didn't have range or stability anywhere near that of Bluetooth.

Many computers now come with built in Bluetooth, especially Apple Macs. If you want to add Bluetooth to a computer that doesn't come with it pre-installed, you should probably use a USB to Bluetooth adapter, although internal Bluetooth devices to install in your computer are available. If you have a laptop and a spare PCMCIA slot, you can get Bluetooth cards for that too.

What Can You Do With Bluetooth?

Mobile phones with Bluetooth are very popular, and so are PDAs -- the instant synchronisation of addresses and calendars to a computer is a useful feature. Other than that, almost anything that would usually use USB can be done using Bluetooth, including digital cameras, mp3 players, printers, and even mice and keyboards. If you take a look through the comprehensive list of Bluetooth 'profiles' (kinds of devices that could, in theory, be Bluetooth enabled), it includes cordless phones, faxes, headsets, and even video.

Basically, more than anything, Bluetooth is a replacement for USB: some say that while 802.11 wireless networking is wireless Ethernet, Bluetooth is wireless USB.

Not Just for Computers.

Part of the power of Bluetooth is that it isn't just used to connect things to computers -- it can be used to connect almost anything to anything else, if both things are Bluetooth-enabled and recognise each other.

Mobile phones, in particular, take advantage of this. Hands-free headsets often use Bluetooth to communicate with the phone. Some cars, for example, now have on-board computers that will connect with a Bluetooth phone and allow you to make hands-free calls, regardless of where the phone is in the car (even if you've left it in your bag in the trunk!)

On top of that, of course, Bluetooth devices can communicate with each other. This has led to some people sending messages from their Bluetooth PDAs to others in close range -- not an especially useful feature, but quite fun. This is called 'bluejacking', and the first recorded instance of it was a man who sent a Bluetooth message to another man's Nokia phone while they were in a bank together. What did the message say? 'Buy Ericsson'.

Since then, it has become possible to send images by bluejacking, and it is widely believed to be the newest advertising medium -- yes, it lets billboards send messages to your phone, a practice known as 'bluecasting'. Whether you think that's cool or annoying, of course, is your choice.
