Now
these days most of the hotels, coffee shops, libraries, airports, universities
and other public places are offering free Wi-Fi option for the convenience of
their customers and also to attract customers. In this way number of free
public Wi-Fi hotspots is growing day by day. But every hotspot is not secure.
Some feel that it is convenient to have Wi-Fi is connected to their mobiles or
laptops or tablets while they are having their lunch or coffee in a shop, which
helps them to surf on net and avoid going over their cellular data limits.
If
you connect to a Wi-Fi network and send information through websites or mobile
apps, it might be accessed by someone else. Some shops will have a
firewall in their wireless routers to protect you, but it doesn’t mean that you
are protected from other people connected to the same network. If you are not
careful about using free public Wi-Fi, strangers can snoop your data and
information like email, social network conversations and also the valuable bank
information also.
If
you want to protect your data and keep your information secure, then follow
these tips to have secure web surfing over public free Wi-Fi hotspots……
Tips to Stay Safe on Free Public Wi-Fi Hotspot:
1. LOOK YOUR SURROUNDINGS:
All
threats in this Digital world are not always technical threats. Stealing of
information sometimes may occur in silly ways. When you are surfing on net
while sitting in a public place like Hotels, busy airport lounge a hacker or
snoop could be looking over your shoulder hoping that you may reveal your
credit card number, username or password.
It
may be some times lead to serious consequences. So you must carefully verify
your surroundings to check no person is looking over your shoulder for your
information.
2. TURN OFF SHARING:
In
your home all devices are connected to single network where you will share
files, printers, documents between one another in the same network or you will
be allowed to remote login from other computers in that network. It is ok if
you are in your own private network. But, when you are connected to public
Wi-Fi hotspot there is chance, that others who are connected to that same
network can hack into your device and access your data.
So
you must conform once before connecting to public networks, that the sharing is
disabled in your device by changing settings. In windows you can change these
settings in the network and Internet settings in control panel.
3. ENABLE FIREWALL:
Now
these days most operating systems include built-in firewall, which will check
and verify incoming and outgoing connections. Firewall protects your system
from others who are trying to get it into your system. By default firewall will
be in enabled position in every system. But check once whether your system
Firewall is active or inactive. If firewall is turned off mode then make it
turn on. Firewall does not provide complete protection but it warns you about
unsecure connections.
4. HAVE UPDATED ANTI-VIRUS SOFTWARE:
Anti-virus
gives your device complete protection from virus. Anti-virus, Anti-Spyware will
protect your system and gives complete protection over internet also. They
inform you when any new suspicious actions occur in your system. Anti-Virus
shows an alert message when known and dangerous malware and viruses are loaded
into your PC and there are any modifications to registry files. So, make sure
that your Anti-Virus is up-to date while you are accessing net over public
Wi-Fi hotspot.
5. BE SURE ABOUT NETWORK NAME:
When
you enter any hotels, airports, shopping malls there is chance of having fake
public Wi-Fi hotspots, which are provided by some people with bad intention and
that right skills to hack into your PC. Connecting to those fake Wi-Fi networks
could place your device into the hands of evil people. If you want to connect
to a public Wi-Fi network in any restaurants or something, confirm once with
the employees working there about the official Wi-Fi network because they would
know that correctly. This is important to check for the official Wi-Fi network
of that public place.
6. HAVE A VPN:
VPN
refers to “Virtual Private Network”. VPN enables computer to send and receive
data across public networks by extending a private network across public
network. VPN provide security by using tunneling protocols and encryption. VPN
routes all your activities through a separate private network. Both paid and
free VPN services available, but paid VPN service provides guaranteed security
than free VPN service.
Make
sure that you have set up a VPN in your device before connecting to a public
Wi-Fi hotspot network so that your information is secured.
7. HTTPS EXTENSIONS AND SSL:
You
know that websites with HTTPS protocol is more secure than websites with HTTP
protocol, because HTTPS websites transfer data with the help of encryption
technique where as HTTP websites transfer plain text which can be easily
accessed by others. For those websites with HTTP protocol, we can make them
HTTPS and transfer encrypted messages with the help of HTTPS extensions and
plug-ins which can be integrated to web browsers.
And
also use SSL (Secure Sockets Layer), which will securely transfer sensitive
information like credit card number, login data and other valuable information
by establishing encryption link between client and server.
Some
HTTPS extensions are: “HTTPS everywhere, Script
safe…. Etc.,”
8. DISABLE AUTOMATIC CONNECT OPTION:
Your
smart phone, laptop and tablets may be set to connect automatically whenever
there are any free public Wi-Fi networks available. This will connect your
device to any open Wi-Fi network without any prior permission from you.
But this may lead your device connecting to unsecure and malicious
networks which are specifically employed for stealing information form users.
So, before going out to any place make sure that automatic connecting to
Wi-Fi networks feature in your device is disabled in order to secure your
device from attacks.
9. IMPLEMENT TWO-FACTOR AUTHENTICATION:
Many
important and popular websites and services provide you an excellent login
option called “Two-factor Authentication” to login into your account. In this
Two Factor Authentication you need to have password and another piece of
information to login into your account. That piece of information may be code
to your mobile or mail or you receive you code by a call. If anybody has got
your password by tracking your transactions through public Wi-Fi loop hole,
they cannot login into your account without code you receive in your device.
So, implement two factor authentications to your accounts.
10. STOP ONLINE BANKING AND SHOPPING:
While
you are outside and using public Wi-Fi hotspot for browsing avoid online
banking and online shopping. Although the banking apps use SSL in order to
protect your information from theft. But it is safe for us to wait until you
reach your home, where you can perform your online transactions. If it is an
urgent case, at that time you use your mobile network instead of using free
public Wi-Fi network to stay safe. This will save your money being theft by
hacking you bank accounts.
11. MAINTAIN UNIQUE PASSWORDS:
Do
you maintain different passwords for different online accounts? It is good to
have different and unique passwords for different online accounts you have. Because
if any malicious person got one of your accounts password, then you can stop
him getting access into other accounts of you. Especially if you have habit of
accessing your accounts through public Wi-Fi networks, It is better to have
unique passwords for different accounts you have. But keep track of all
passwords you own.
For
so many reasons I feel good to use mobile network, because anybody can’t track
our information. So, avoid free public Wi-Fi hotspots as much as possible to
stay safe. If I missed any tips to stay safe on public Wi-Fi networks, please
