2.4.7. Web Browser Security

How do we send and receive all the information from the Internet? in postcards? in sealed envelopes? in various sealed packages and in indecipherable languages?

Lesson goals and objectives

In this lesson you will learn:

  • to identify the aspects that mark a safe navigation
  • to know the procedures for safe navigation. 

A very important part of the time we are connected to the Internet is spent surfing the web using our favourite browser. We usually do this without paying much attention to our security and without understanding or knowing the ways in which we can do it with a higher degree of security.

History, Cookies, Private Browsing, Authentication, Secure Pages, Digital Certificates, are some of the terms that we will have to familiarise ourselves with little by little.

1.4.7.1. Private browsing and browsing history

Private browsing allows us to surf the Internet without the browser storing the web pages we have visited in its history.

It would be very convenient for us to familiarise ourselves with the procedure for accessing private browsing in the search engine(s) we usually use.

1.4.7.2. User authentication in Web browser

On many occasions we must authenticate ourselves in order to use web services, that is, we must prove that we are who we say we are. Something like showing our ID card with our photo when doing some business in a government office. More and more web services allow us to access by “authorisation” provided by another Internet service with a valid reputation that guarantees who we are.

But that has a “price” that is not always the direct payment to the provider.

1.4.7.3. Safe browsing (SSL certificate, Cookies …)

Information we send or receive on the Internet can be intercepted by other people on the same network.

For this reason, more and more Internet services are making available to us secured and encrypted connections so that all data sent and received between the service or company and our team cannot be “readable” even if it is intercepted.

The image of a closed padlock on the navigation bar of our search engine is a guarantee that the page of that service is safe.

1.4.7.4. Fake, fraudulent or scam websites

In the same way that we do not deposit our savings in the hands of a “gentleman” who carries a sign on his chest that says: MOBILE BANKING

On the Internet, in addition to competent, professional and responsible companies and organisations, there are many others that only seek to deceive and swindle us.

We must be vigilant and prepare to detect these white-collar criminals.

1.4.7.5. VPN safe browsing

We already know that there are more and more Internet services to offer secure data transfer services but can we “extend” this extra layer of security to all our Internet transactions?
