2- To increase the protection of the devices, it is important to have the best security tools: a good antivirus will help you improve security.

The combination of fully updated equipment, security software, and specific control options improves and increases security guarantees.

5- Look for official WiFi networks or with “guarantees”: there are usually innumerable access points, and it is very important to use mainly those that are reliable. For example, in a restaurant, the idea is to ask for the exact name of the WiFi since, at times, hackers create access points that mimic official names to deceive occasional users. Once the official name of the access point is consulted, we must check if it has security. The usual encrypt connection systems with WPA2 passwords, which helps maintain network security.

6- Make responsible use: once you have verified that the equipment and services are prepared and there is an official confirmation about the WiFi, the following advice is to make responsible navigation. Be aware that the network is not yours and that you should limit your browsing to content that does not include sensitive information.

7- Common sense applies: it is very inadvisable to make payments or other online banking operations or send private data through these connections. It is best not to access or share sensitive data while using public networks since we do not know if they can be used with bad intentions.

8- Browse pages with HTTPS protocol and use VPN: these are systems that add security layers and complement the security measures mentioned above.

9- Follow the usual security practices: use strong passwords, do not repeat the passwords in different services, and disconnect from the network if you are not using it.

10- Last but not least, remember that access to public WiFi networks should be the last alternative.
