Currently, his era of wireless networks, many places in Indonesia today to apply free internet area better known as the HOT SPOT. There are applying for free and some are implemented by way of pay, and some telecom operators who participated in developing this business segment.
In some local areas, the use of wireless networks is quite helpful. This is because no need for such a long cable stretched it to a means of communicating with the computer one computer to another. It’s just that some people once questioned about the security of this wireless network.
Talk about security will not be separated from economic elements, such as business, robbing even. People will not secure more if a secured just a regular data .. different if the data that are behind all of that high economic value. This means, for example, we want to take a very important data behind a particular company. But to break into its security system we have to provide dozens of PC devices. Here we are going to count, how big its potential for cost data with which we should spend. So is the success rate for doing so. That is why many banks, service providers in cyberspace suggest to change your PIN or password periodically. And as much as possible using various combination of them, including small and large letters in the password or PIN number is.
So talk of security, in this world nothing is really absolutely safe. The house that we layered key was actually still be in collapse. Only a matter of time for hack, the more layers the longer we have to break those keys. So also in cyberspace, its still all there is no absolutely safe. So everything turned on aspects of economic value.
