You think free wi-fi browsing is safe?
With the high traffic on the Internet today as people log into various websites, there is need for people to know that their privacy can be violated. This happens especially when someone is using an smartphone, laptop, tablet or a PC to access a public network such as Wi-Fi hotspots. Most of such hotspots can be lucrative dens for hackers who access personal information without authorization thereby compromising people’s privacy. This problem calls for the need to protect such hotspots with firewall, passwords and encryption among other protective measures. Today, VPN provides the ultimate solution by ensuring that people get protected while they log into remote computers through public networks all the time.
The major problem with most free public Wi-Fi hotspots is that hackers might be using them to attack their prey. A prey is anyone who log into such hotspots whether knowingly or unknowingly. It is good to be cautious while logging into any network that is not password protected or one that is not WPA or WEP protected. This is because personal information such as username and account passwords can be hacked very easily. Hackers usually see such information as plain texts. Additionally, stored passwords and user information on computer hard disks or system memory can be accessed very easily in such public networks.
Most sophisticated software such as keylogger can be used to monitor the activities of users of Wi-Fi hotspot. Keylogger is very useful in recording the keyboard data entries of users of a particular network. Additionally, login activities of users are recorded and stored in the computer servers. Such data is very helpful in accomplishing the intentions of hackers for personal gain. This is very dangerous because important information can be leaked out to the public to tarnish the reputation of individuals as well as compromising the security of personal financial information.
For security purposes in such public networks, it is good to log into secure networks that require passwords. Such networks are safe since they are usually WPA or WEP configured. This means that hackers will find it difficult to succeed in such an environment because the traffic of data packets will always be encrypted. Another way to enhance security on public Wi-Fi hotspots is to configure personal computers or mobile gadgets such as iPhones, iPads and tablets not to automatically authorize connections to networks in their range.
Today, logging into public hotpots can be made more secure by setting up Virtual Private Networks that are controlled by a qualified administrator. Using any VPN services like Switch VPN, is the most convenient method to use in such a case. There are two commonly used methods of setting up VPN. One of them is by encrypting data that pass through networks. This is usually done the use of either firewalls or by the use of encrypting routers. The firewall and routers do all the encrypting and decrypting work without any need of a special software program or client computers whatsoever. The use of the second requires one to have an encrypting router, a firewall or a VPN server. These three items should be at the receiving end. Additionally, there is need for VPN client software installed on a personal computer. All these items depend on whether the traffic operation is one-way or two-way.
