As the number of internet-enabled devices increases, so do digital security risks. While we're exposed to cyberattacks even with secure Wi-Fi at home, the risk is even greater when we access open Wi-Fi networks. Staying connected while traveling is key, but the security and protection of your data and devices is crucial. In this article, we'll tell you about the risks associated with open networks and how you can avoid and protect yourself, especially while enjoying your travels. Real risks of public Wi-Fi networks in tourist destinations Public Wi-Fi networks are a draw in airports, cafes, and hotels. However, their open nature means anyone can connect, which also makes it easier for hackers to access your data. In this environment, an attacker can intercept the information you send and receive. This includes passwords, emails, and credit card information. According to a Kaspersky study , a significant percentage of users in Latin America don't consider the risks of online security. Man-in-the-middle attacks One of the most common methods used by attackers on public networks is the "man-in-the-middle" attack. In this scenario, a hacker interposes himself between your device and the network, capturing all the information being transmitted. Imagine you're using your laptop to make a hotel reservation. Unknowingly, your information could be captured along the way. To protect yourself, avoid conducting sensitive transactions over open Wi-Fi networks and always use secure connections. Phishing attacks: a sophisticated deception Phishing attacks are another significant threat travelers should be aware of. This type of attack relies on tricking people into revealing personal information, such as passwords or credit card details, by posing as trusted entities. Attackers often send fake emails, text messages, or even create websites that mimic legitimate services, such as banks or payment platforms. In a travel context, you may receive an email that appears to be from your airline, requesting you confirm your flight information. If you click on the link provided, you may be directed to a fake website that steals your credentials. To protect yourself, always verify the sender's address and avoid clicking on links in suspicious emails. Also, make sure the website is secure and legitimate before entering any personal information. Prevention is key to avoiding these digital traps. Security technologies for connections in hotels and airports Despite the risks associated with using public networks, you may need to use them at some point. While there are no foolproof protection methods, we'll share some of the best measures you can implement to strengthen your online security and protect your devices and data. Use a VPN for added security One of the best ways to protect your information on public networks is to use a virtual private network (VPN). A VPN encrypts your connection, making it much harder for attackers to intercept your data. When you connect to a VPN, all your internet traffic is redirected through a secure server, protecting your information even on unsecured Wi-Fi networks. Plus, many VPNs offer additional features, such as ad blockers and malware protection. While there are many free services, most have speed or data usage restrictions, which can limit your experience. Since a cyberattack could cause significant damage, investing in a good paid VPN is probably the best option. Two-factor authentication Another layer of security you can implement is two-factor authentication, or 2FA. This adds an extra level of protection, as it requires you to enter an additional code sent to your phone every time you log into an account. This means that even if someone obtains your password, they won't be able to access your account without the second factor of authentication. Using 2FA is a best practice that can safeguard your data in the event your connection is compromised.

Tips to keep your information safe while traveling When it comes to protecting your information and devices, there's no such thing as too many measures. In addition to the recommendations above, there are some simple practices you can implement that will help strengthen your online security: Disable auto-connect to Wi-Fi : This will prevent you from accidentally connecting to unsecured networks.
