In today's online world, public Wi-Fi networks provide unmatched ease for quickly accessing the internet. However, this convenience still carries a significant danger of exposing sensitive details about possible online dangers. Accessible wireless networks are unsafe, and your Personal information could always be in danger when you connect. To explore these networks safely, it's imperative to confirm the network's validity you are connecting to, ensuring it is provided by reliable sources, such as airports, cafes, or libraries, and avoiding suspicious or essential names that can suggest malicious intent.
Additionally, securing a virtual private network (VPN) connection is supreme. A VPN builds a safe channel for your information, shielding it from suspicious eyes and possible hackers on the same network. With numerous VPN providers readily available for various devices, encrypting your connection considerably lowers the danger of unauthorized entry to personal information, such as passwords and money information, even when using public Wi-Fi networks.
How to Keep Safe When Using Public or Free WiFi
Network Verification and Configuration
Step 1: Verify That You Are in the Right Network.
Ensure that you are linked to the appropriate network. Malicious actors could build networks that appear innocent based on their name but point you toward a network configuration to see your internet surfing. This means If you input passwords or login information into websites, the hacker can steal your data. To protect against this, carefully examine the network name and ask an employee or examine the business's signage to make sure the network is authentic.
Renowned networks, like those of familiar coffee chains, are less suspicious given that the corporation runs the network as a service with their business. Known networks are safer overall than random accessible WiFi networks that may appear on your phone in a public area. When using a cafe or library, the most convenient way to be safe when connecting to their WiFi is to request the network's name or SSID from the employees you would connect to.
Step 2: Turn Off Auto-Connect.
Numerous gadgets like tablets, laptops, and cell phones have automatic connectivity settings. This setting makes it easier for your devices to connect to nearby networks. This is acceptable on reliable networks but can also link your devices to potentially dangerous networks. You can turn off this functionality using your device's settings feature. Keep these settings turned off, particularly when visiting distant locations. As further caution, you can check "forget network" when using open Wi-Fi.
You should also watch your Bluetooth when you are out in public places. Bluetooth connectivity allows several gadgets for mutual communication; An attacker may search for open Bluetooth. Signals to get into your gadgets. Keep this function on your phone; others leave your electronics off when visiting a new place.
Step 3: Turn Off File Sharing.
Ensure that the file-sharing feature is disabled while on public Wi-Fi. Depending on your operating system, you can use the control panel or system options or turn off file sharing. One of the features for file sharing is AirDrop, which you will want to turn off. Some operating systems, such as Windows and PCs, will turn off file sharing on your behalf by choosing the "public" option when first connecting to a new public network.
Steps to turn off file sharing
On PC:
Go to the Network and Sharing Center.
Then, Change advanced sharing settings.
Turn off file and printer sharing.
For Mac:
Go to System Preferences.
Choose Sharing.
Unselect everything.
Next, click on AirDrop in Finder, and select Allow Me to be Discovered by No One.
Locate and disable AirDrop in the Control Center for iOS devices.
Step 4: Secured vs. Unsecured.
Generally speaking, there are two public WiFi networks: Secured and Unsecured. Whenever possible, link up with safe open networks. An unsecured network can be linked without security measures like a password or login. A secured network typically calls for the user to accept the terms and conditions, register an account, or input a password to establish a connection to the network.
Step 5: Forget Networks.
Once you disconnect from any public or free WiFi, it is suggested that you forget it; this will stop your gadgets from automatically connecting to these networks and any ones with the same name in the future. Below are the instructions for forgetting a network connection.
For Windows users – On the Network's name, uncheck the "Connect automatically" box before connecting. Alternatively, you could navigate to the Network and Sharing Center under the Control Panel, click on the Network's name, then on "Wireless Properties," then "Connect automatically while nearby this network. This should be unchecked."
For Mac Users – Navigate to System Preferences, select Network, then under the WiFi section, click on Advanced. Under the Uncheck "Remember networks this computer has joined" in the advanced section." You can also remove any other registered networks by choosing them and clicking the minus button.
For Mobile Users – Long-press the name of the Network you are on and select "Forget Network." Being aware and cautious of these potential dangers can spare you much stress. Just do the periodic inspections regularly and exercise caution every time you ask for the password of the WiFi. We are working with Globe on several helpful articles and tutorials for #makeITsafePH to help you be more informed and attentive when logging in online.
Step 6: Know your Network.
Hackers commonly employ fake Wi-Fi hotspots with names that seem close to authentic ones to trick others into believing they are real. Before logging onto a public network, ensure you know the precise name of the secure network you intend to utilize. If you are unsure, asking somebody at work never hurts.
Step 7: Trust your Instincts.
If a webpage appears questionable, it probably is. Unexpected redirects, pop-ups, and spam are all warning signals that you should shut off your browser window immediately. Moreover, search engines like Google frequently provide warnings following unsafe links to help you avoid visiting a website that might be dangerous or have been compromised.
Security Measures
Step 8: Use a VPN.
You should set up a virtual private network or VPN through your gadgets. A VPN is the safest choice for internet privacy on public Wi-Fi. Your data is encrypted while passing through the "tunnel" to and from your device for protection so that your data is not apparent while traveling through a network. VPNs or Virtual Private Networks, aside from faking which country you are in, give your connection more protection and privacy by encrypting and tunneling your transmitted and received data and replacing your IP address. VPNs can be utilized by smartphones and PCs alike. But exercise caution and stick to VPN companies you can trust, as this could backfire, and instead of Defending your gadget, it could put it at risk. When utilizing public Wi-Fi, a VPN, you are gaining access to a VPN tunnel, or secret network, through which you send and receive information, enhancing your connection's security with an additional layer. While some VPNs are free, you will likely have to pay for the most security features. Be sure to purchase a VPN from a reliable supplier to ensure your data is safe.
Step 9: Make Use of Multi- or Two-Factor Authentication.
Use multi-factor authentication (MFA) with your details when logging in to websites. This means you have a second verification code sent to your phone over text message, an app, or a tangible key that further protects you. So, even if a hacker gets your password and username, they cannot access your accounts without an authentication code.
Step 10: Use Antivirus Software.
Also, make sure to install the most recent antivirus software version on your laptop. Antivirus programs can assist you in staying safe when utilizing public Wi-Fi by identifying malware that might get into your system when using the public connection. An alert will alert you if your device has any known viruses stored on it, if there is any suspicious activity or attack, or if malware enters your computer.
Step 11: Enable Any Extra Security Measures.
If your device or application has extra security elements such as secondary pins or two-factor authentication, then it would be sensible for you to use them. If you would be hacked due to using a public WiFi network, then at least you have an additional security measure.
Step 12: Stick with HTTPS.
As of a few weeks prior, Google Chrome lets you know when this website is using an unencrypted HTTP connection rather than an encrypted HTTPS encryption by designating the previous as "Not Secure." Pay attention to those warnings, especially on public Wi-Fi. When using HTTPS to browse, can people on the same Wi-Fi network as you not intercept the information being transferred between you and the website server you're connecting to using HTTPS? They find it simple to observe what you are doing.
Explore the internet, including an SSL certificate, while on public Wi-Fi. A website has an SSL certificate in cases when the URL starts with "HTTPS." Website addresses that begin with "HTTPS" are encrypted, enhancing the security and safety of your online activities. If you join an unprotected wireless network and use "HTTP" instead of "HTTPS" addresses, everybody else on the network could be able to see the traffic.
Step 13: Protect Against Cyber Attacks.
Taking additional safety measures to safeguard your smartphone or PC from attacks can go a long way toward ensuring your security. Even if you know, there is no perfect solution for protecting oneself when using public Wi-Fi. It is essential to bolster protection with additional layers if someone can access your devices.
You may prevent unwanted connections to your computer while on Wi-Fi by activating your firewall. Firewalls monitor the network traffic entering and leaving the system, preventing potentially harmful programs from connecting secretly without your knowledge. Installing trustworthy antivirus software can help to further enhance the security of your data and devices from ransomware, spyware, viruses, and additional viruses that could infiltrate you when utilizing a shared network on your PC.
Finally, update your software regularly, including your operating systems, firewalls, antivirus software, and applications. Updates frequently include necessary security patches that fix vulnerabilities. Updates are usually shared publicly, Which implies that there may be vulnerabilities in older versions. For the world to see.
Step 14: Another Tips Online.
Before accessing free public WiFi:
Activate your virtual private network.
Delete the cache and history from your browser.
Verify that your antivirus program is active.
Kindly turn off the Bluetooth discoverability settings so that others cannot force your gadget to connect to theirs.
Ensure that 2FA or MFA, or multi-factor authentication and two-factor authentication, is enabled for the most critical accounts in your life.
When utilizing open hotspots:
Connect only to networks provided by organizations you may physically link to.
When using an online account, log out of any you are not using.
Applications you do not intend to use should be finished or closed.
Please keep all of your passwords organized by using a password manager and use it to autofill your login information.
When using public networks, do not input sensitive information like credit card numbers, passwords, SSNs, home addresses, etc.
Limit the WiFi networks you have stored to those you trust.
After a public network disconnect:
Use antivirus software to check your gadgets for malware.
Restarting your device can assist in severing its connection to a possible intruder.
Remove any unnecessary networks from your list of preferred networks.
Also, use your mobile hotspot rather than free public WiFi if you can.
Data Protection and Privacy
Step 15: FBI Warning About Encrypted Websites - HTTPS.
The FBI has warned about web pages with addresses that begin with "https." The presence of "https" and the purpose of the lock icon is to show online traffic, and it is encrypted so that visitors can securely share data. But still, cybercriminals are now banking on the public's trust by enticing visitors to harmful websites that look secure and use HTTPS when they are not.
FBI's Recommendations:
Do not just believe the email's name; inquire about the purpose of the email content.
If you receive suspicious emails from a known contact with a link, confirm the message is authentic by contacting the contact through phone or email. Wait to respond to a suspicious email.
Check for grammatical errors or incorrect domains within a link; for example, if an address that should finish in ".gov" instead ends in ".com."
Never trust a webpage because it has a "https" or the lock icon in the browser's URL bar.
Step 16: Accessing Sensitive Information Not Recommended.
While utilizing an open WiFi network, it is best to refrain from accessing private data. Suppose you need to use the internet to look up directions or for other less sensitive purposes; you can certainly do it. Despite using a VPN, reaching individual bank accounts or comparable private, sensitive information, such as social security numbers, is still not recommended on unsecured public networks. Even secured public networks can be risky. Use your good judgment when deciding whether to use free public WiFi to access these accounts. Using the hotspot on your smartphone could be a preferable function for financial transactions.
Step 17: Do Not Give Away Too Much Info.
When registering for WiFi in public places, exercise extreme caution if you are getting asked for several private informational pieces, such as your email address or your phone number. If you must connect to these networks, stick to places you trust and consider using a different email address from your main one.
Stores and restaurants that do this wish to be able to identify you on various WiFi hotspots and tailor their marketing accordingly; thus, you have to choose whether the trade-off is worthwhile for some free internet access.
Again, register with as few distinct public WiFi networks as you can. Are your phone or Free WiFi hotspots provided by your cable provider where you are now, for example? You can get linked through a service you previously signed up for. That is usually better than handing your information to another organization or company.
Step 18: Keep Track of Your Devices.
Never put down your smartphone, tablet, or laptop alone in an open area or vehicle. Despite your caution when using a Wi-Fi network, that will not deter someone from robbing you of your possessions or having a covert look at your information. Pay attention to your surroundings and consideration of others around you.
Step 19: Limit What You Do While Using Public Wi-Fi.
The public networks are excellent for doing tasks such as scrolling the latest news headlines or completing Buzzfeed tests, but we do not advise doing so for the important stuff. Accessing any online protected by a password account including social media accounts, or online purchasing involving the input of a credit card number, are items that are best left for using on your dependable home network or even your cell phone network.
Additional Precautions and Tips
Step 20: Other Online Safety Tips.
Here are a few guidelines for internet safety, particularly when utilizing a public Wi-Fi connection:
Use strong and unique passwords.
Encrypt your devices.
Watch out for fake emails.
Take care while sharing anything on social media. Too many personal details can assist password-guessing hackers.
Remove out-of-date information that is no longer necessary.
If a network asks you to install additional applications or browser extensions, do not connect.
Ensure your software and patches are up to date and installed on your devices to protect against known issues.
Step 21: Use Browser Extensions.
Think about adding an extension like HTTPS Everywhere, which will compel every website you visit to use “HTTPS.” This is an extension for Opera, Chrome, and Firefox produced by working with the Electronic Frontier Foundation and The Tor Project. Using this extension can reduce the possibility of visiting a dangerous website.
Step 22: Use a Privacy Screen.
If you must access private data in public spaces, consider installing a privacy shield on your electronics. A privacy screen will darken your screen for all users except yourself, keeping fraudsters from being able to take a picture or duplicate any private information you own.
Step 23: Check What You Are Signing Up For.
We know we are probably pointless to say, but familiarize yourself with the terms and restrictions applied before connecting to a public Wi-Fi network. You might not always comprehend every word, but you must always be able to identify any significant red flags, particularly around what type of information is being gathered about your session and what they are doing with it.
If you find the related policies challenging to breach, a quick web search should bring up any issues or concerns other users know. Nothing is essentially negative regarding terms and conditions; they safeguard the Wi-Fi provider, but do not merely click through any pop-up screens you encounter randomly. And if they ask you to install any add-on programs or browser add-ons, back away quickly.
Step 24: Keep Your Operating System Up to Date.
It is essential to update your operating system frequently, known as OS. OS updates often contain important security updates that can further protect your gadget from WiFi dangers. After getting the most recent updates, you can access the internet safely with the most up-to-date security features.
Step 25: Remember to Log Out.
Make sure you log out after browsing any services you are using. Also, check your settings to ensure that your device will not automatically rejoin and instead "forget the network" to that network again if you are inside range without your consent. This can reduce the amount of time your gadget is connected to a public network.
