La importancia de la seguridad

Welcome to the Security Course for Cryptocurrency Users where you will learn how to reduce the security risk you are exposed to in the digital world.

Why should you take this course?

Whether you are a Web3 user or not, you should take this course. We all have a digital identity, we have accounts in banking applications, social networks or other types of apps where part of our identity and information is stored.

There are people with malicious intentions out there that every day think of new ways to steal digital information and use it against us. Even more so in the decentralized world where we are 100% responsible for security and no one will be able to help us if we are scammed.

What will you learn about computer security?

Throughout the course, we will explore the different layers we use directly or indirectly when interacting with the digital world. We will see tips or suggestions to keep in mind about each of the following layers:

• Access devices and user interfaces (cell phones, tablets, notebooks, etc).
• Network interfaces through which the information travels (Protocols, ISP)
• Types of sites you visit (Cloud, P2P, de-centralized/centralized sites)
• The authenticity of the information we access (Metadata).

Let's start by evaluating the security of the devices we use to access the digital world.

Security in the devices we use

Nowadays, we all have a cell phone, a laptop or desktop computer, a smart watch, etc.

You should always consider updating the operating system of all devices and do not allow time to pass without updating it. Whether it is Windows, MAC or Linux, allow the OS to be properly updated every week, since such updates usually correct security vulnerabilities or improve security.

The same goes for mobile devices, whether Android or IOS, make sure to update the operating system. If you don't have the memory space to do it, maybe it's time to buy a new one. It is not at all advisable to be a Web3 user and use outdated devices.

Clean your computer regularly for possible threats or malware. If you suspect that your device is infected, format it to be sure that you will not have problems with it.

Avoid using pirated software of any kind. If you ever installed an unofficial WhatsApp version, it's a good time to uninstall it and clean your device.

Conclusion

Without going to the point of obsession, you should start being more considerate and take care of the software on your devices. Maybe today you have few digital assets to take care of, but in a while they may grow and that is where the vulnerabilities that we do not take care of today manifest themselves.

This course has just begun. I invite you to continue and, class by class, you will learn how to be more cautious and reduce the risk of suffering any theft of our digital assets.
