Public Wi-Fi is a great convenience for people who work remotely, travel frequently, or want to check social media and email when they’re away. But in the past, open Wi-Fi has been discredited as a dangerous internet location where your information is at risk. Is this still true, and if so, what exactly are the dangers of using a public Wi-Fi network?

The risk largely depends on the type of Wi-Fi network you are using. Public Wi-Fi networks, found in airports, coffee shops, and other public places where you should never use a public Wi-Fi network, often require you to enter a password to access the Internet Enumeration. ;

This is considered “secure Wi-Fi”. However, you often have to “log in” to verify the terms and conditions of the deal, or maybe nothing at all. This should be a red flag that this is an open Wi-Fi network, also known as an unsecured network.

The public Wi-Fi network is not secure

When you’re at home, you can take steps to protect your home wireless network, such as using a strong router password, which devices can connect to your network, and turning on the encryption that protects your wireless network. protects the. It does not protect. It encodes the information sent over the Internet. A code that others cannot read. But when you’re using Wi-Fi at your favorite coffee shop, there’s not much you can do to control your network security.

Does it matter if the network is not secure and you log in to an unencrypted site or to a site that only uses encryption on the login page? Other network users can see what you see and submit what we do. . They can hijack your session and log in like you. Your personal information, private documents, contacts, family photos, and even your login credentials may be on hold.

A scammer can also use your account to impersonate you and mislead people on your contact lists, or they can test your username and password on other websites, including sites that store your financial information. Oh, If a scammer has access to your personal or financial information, they can steal your identity.

What can happen if I use an open Wi-Fi network?

You risk connecting to a malicious access point; A hotspot is simply a place where people can access the Internet, such as at an airport, restaurant, or university. “Malicious access points … may look legitimate, but they are actually fake.” Cybercriminals can often steal passwords, install malicious software, and spy on your computer when it is connected to a different Wi-Fi network a valid network.

“When a user connects to a rogue Wi-Fi network or access point,” they are inviting hackers to their device, “which opens the door to attack. When they try to connect to a website, For example, your bank, the malicious access point redirects you to a website that looks like your bank but is not secure. When you enter your password, credit card number, or other confidential information, hackers will steal.

Even if you connect via HTTPS to a legitimate website on a legitimate network, cybercriminals can still obtain information about your browsing habits. This is because the domain name system, or DNS, is not always encrypted. In other words, hackers can see the domain name of the sites you visit, like RD.com, but not the specific pages you visit or the information you enter on that domain.

Know your virtual private network

The only guaranteed way to avoid becoming a victim of a MitM attack is to stay completely away from public Wi-Fi networks or to use a VPN. These virtual networks encrypt or protect the information that enters or leaves your device when you use Wi-Fi.

A VPN may seem like the perfect solution to avoid the risk of having your Wi-Fi credentials stolen. And they can be, but only if you know they exist.

Never use a VPN when connecting to a public Wi-Fi network. However, the fact that more than half of those surveyed believe that their identity is likely to be stolen after entering information on a public Wi-Fi network raises the question of why more people use VPNs regularly. What are you doing? Lack of awareness can be a major factor. If cost is also an issue, people should weigh the risk of identity theft against their desire to protect their private information on public Wi-Fi networks.

Choose a secure network

When you want to choose a Wi-Fi access point to log in, try to find the one that blocks it. Read well In general, if you see the lock icon, it means that you cannot access it. On the iPhone, if you click on an unsecured network, even if it is yours at home, you will get a warning that says Security Alert.

Of course, this is not a hard and fast rule. Some access points do not display a lock because they have “fenced yard” protection; You must log in through a browser to access the Internet.

It is best to stick to access points where the provider, be it a conference, hotel, or coffee shop, gives you a clear network to choose from, as well as a password to grant access. Then you know that you are at least on the network that you should be using.

What is a VPN?

A VPN allows a user’s devices to connect to a private network through a public network. VPNs were created to securely connect devices within a corporate network to private servers on the Internet. Those networks allow users to access their company network remotely from their home, another office or anywhere else using public WiFi.

How does a VPN work?

At its most basic level, a VPN tunnel creates a point-to-point connection that cannot be accessed by unauthorized users. Different VPNs will use different tunneling protocols, such as OpenVPN or Secure Socket Tunneling Protocol (SSTP). The protocol used may depend on the platform on which the VPN is used, such as SSTP used in Windows operating systems, and will provide data encryption with varying strengths. The endpoint device must be running a VPN client locally or in the cloud. The client will run in the background. The end-user is not aware of this unless there are performance issues.

Using a VPN tunnel, the user’s device will connect to another network, while the data is encrypted and the IP address is hidden. This is what will hide private information from attackers or others hoping to gain access to a person’s activities. The tunnel will connect the user’s device to an exit node in another remote location, making it appear that the user is in another location.

The VPN will combine the user’s search history with the IP address of the VPN server. VPN services will have servers located in different geographic regions, so it appears that the user could be from any of these locations.

Performance can be affected by many factors, such as the speed of users’ Internet connections, the types of protocols used by a VPN provider, and the type of encryption it uses. In the enterprise, performance can also be affected by the poor quality of service (QoS) outside the control of the organization’s information technology (IT) department.

The kill switch is a security feature of last resort on some VPN products. If the VPN connection is interrupted, the disconnect switch will automatically disconnect the device from the Internet. This way, there is no chance of IP address exposure.

HTTPS Use

If you don’t have access to a VPN, make sure you only visit encrypted sites, it can also help protect your data from some of the threats mentioned above.

Look for HTTPS at the beginning of the website address. This means that the connection between the browser and the webserver is encrypted, so any data sent to the website will be protected against concealment or manipulation. Most browsers also include a lock symbol at the beginning of the address to indicate that the site uses encryption.

Enable Firewall

All operating systems come with a firewall that protects your system from threats on the network. In Windows 10, this firewall is Windows Defender, which some users are tempted to turn off. Whatever operating system you are on, make sure you have enabled the firewall if you frequently connect to public networks.

Avoid sensitive sites

Avoid logging into any online account that stores your confidential information. The list can be long if you think about it: retail websites, healthcare provider sites, banks or other financial institutions, email accounts, and social media profiles.

Conclusion

Security and privacy should be your first concern when connecting to a network. This is why you should always choose a private network over a public network.

Setting up your private network can seem much more complicated than using a free and readily available public network.

However, the truth is that public networks are vulnerable and you should avoid their use, as doing so increases the chances of attackers exploiting your device.
