Public Wi-Fi is known as a wireless connection to the internet that is accessible
in public places like hotels, airports, restaurants, shopping malls and libraries,
offering free or easy access to the internet. A public Wi-Fi network can either
be open (unsecured) or encrypted (secured). An encrypted public Wi-Fi
requires a password or account creation to login for access. An open public
Wi-Fi network, on the other hand, does not require a password to connect, and
this means anyone can join the network without any authentication which
makes it more vulnerable and prone to hacking.
It is important for internet users to be aware of the risks associated with using
unsecured open free Wi-Fi networks and how the public can stay safe while
surfing the internet. While it can be tempting to connect to open networks for
free Wi-Fi, a general lack of security measures makes these hot spots easy for
hackers to intercept sensitive information like passwords, credit card numbers,
and personal information.
Using public Wi-Fi poses several cybersecurity risks, including Man-in-the-Middle
(MITM) attacks where hackers intercept and alter communications, packet
sniffing that allows cybercriminals to spy on users’ online activities, and
malware distribution through exploited device vulnerabilities that can lead to
spyware or ransomware infections. Additionally, hackers may create malicious
hotspots which are fake Wi-Fi networks designed to trick users into connecting,
enabling them to steal data or redirect users to harmful websites.
HOW TO STAY SAFE ON OPEN WI-FI NETWORKS
- Make use of Virtual Private Networks (VPN): One of the best ways to
minimise public Wi-Fi security risks is by using a VPN. VPN encrypts your
internet traffic, making it much harder for hackers to intercept and read
your data. - Enable Multifactor Authentication: Consider enabling multifactor
authentication on accounts in addition to passwords as an extra layer of
protection. Even if someone gains access to your details and login
credentials, they will still need the second factor, e.g. a verification code
via your phone or email, to have full access your account. - Avoid Sensitive Transactions: Minimise sharing sensitive information when
using public Wi-Fi. An addition, also avoid making financial transactions
such as entering credit card details, making payments or inputting
banking information while using public Wi-Fi. Confidential information
such as banking and login details should only be accessed using secured
internet. - Turn Off Sharing Features: Public networks make it easier for others to
access your device if file-sharing or printer-sharing features are enabled.
Turn these features off on device system settings while on public Wi-Fi. - Disable Auto-Connect: Most devices have an option to automatically
connect to available Wi-Fi networks. Disabling this feature can prevent
your device from connecting to insecure or rogue networks without your
knowledge. - Keep Software Updated: Ensure that your operating system, browser, and
security software are up to date. Software updates often contain security
patches that protect against newly discovered threats. - Enable Device Firewall: Enable the firewall on your device to add another
layer of protection against potential intrusions from public Wi-Fi networks
Moreover, public Wi-Fi networks seem to be more convenient in providing easy
access to the internet, however, they come with significant cybersecurity risks.
Therefore, individuals must remain cautious while using public internet access
and ensure the best security practices. By staying informed and practicing safe
browsing habits, individuals can make use of public Wi-Fi without compromising
their privacy or security.
