The issue of WiFi network in Bangladesh prospective.

If we want to make digital our country we need Wifi network.One day public WiFi is everywhere we go, such as at coffee shops, airport, rail station, park, libraries, print shops and even some fast food restaurants.We have already WiFi in some university like university of Dhaka. We can easily connect our laptop to it and we will be surfing the web in no time at all. Although it is convenient, it may not be safe. Hackers and scammers can tap into our unsecured connections and easily steal your personal information. We can protect your computer if you take a couple of precautions.

When we are using public WiFi, we have to sure to use a firewall. Firewalls give us extra protection, though not foolproof, from people trying to scam your information. Windows XP and Vista operating systems have built in firewalls.We can set up a firewall on computer by visiting some website as Microsoft website.

Public WiFi locations are not the place to conduct business that involves the use of private information. If a scammer hacks into a computer, all of us -- or our friend's -- personal information will be obtained. Even if we have a firewall, there is no guarantee that our information won't be stolen. Save business-related work, valuable data by using private network.

It may seem like a public WiFi location is the perfect place to do a little online shopping. It is, in fact, the worst place. While online shopping, we are likely to use our credit card to pay for our purchases. This places our credit card information out in cyberspace for dishonest people to use.

The suggestion is Feel free to browse your favorite online stores, but save the actual purchase until you have a secure connection.Never balance your checking account, or use any other online banking service, when accessing the Internet at a public WiFi location. Besides the stranger that may be looking over your shoulder, there are other people that may be tapping into your network connection. They can acquire your username and password as well as all your personal information.

We have to sure when using public WiFi that we disconnect any networked computers and file sharing. If a hacker does manage to access this computer, they will also be able to access any computers linked to that network. All the information stored on the computers will be accessible.

We should be aware of using digital network that doesn't mean I do not like WiFi network or I am opposing "Digital Bangladesh". I want to say our student should use it or the person have less valuable data to loss he should use it and important data must be used by taking above precaution.
