diciembre 26, 2019

Surfing the Internet has revolutionized the life of all of us, making everyone more productive and making information accessible to anyone, just a few mouse clicks are enough, but on the Internet there are also numerous dangers, well hidden: just a distraction is enough to find the infected PC or have your personal data stolen (including credit card or bank account information). In this guide I will show you how to check if a secure site with some tools integrated in browsers plus some extensions that you can use to make browsing safer.

Let's start by explaining the meaning of a term you often hear, that is phishing.

The phishing a computer scam carried out by sending an e-mail with the counterfeit logo identical to that of a credit institution or an e-commerce company, one of the most common cases in which you try to pass the e-mail for an original communication of Poste Italiane, but not only, this happens with many banks and Paypal.

In these emails the evildoer invites the recipient to provide confidential personal data (data that will be stolen from us such as: credit card number, password to access the home banking service, etc.), motivating this request for technical reasons, all by connecting to a link in the email, which if you go to see for good does not match to that of the real banking institution.

Precisely for this reason, it is very useful to check whether the site on which we are sent actually corresponds to that of the sender who contacted us. For example, if you contact us Italian post, we write on Google Italian post and compare the links indicated in the email and those found in google search and this is only the first step to do to be sure of a site.

Another risk we can take is to catch a malware or virus by connecting to an unsafe site. This can lead, at best, to a slowdown of our computer, but in the worst case, the loss of all data or even the theft of them.

To check if a site contains a Malware or a Virus, we can use one of these 2 online services:

The first thing to do is to copy the URL of the website we want to analyze and paste it in the dedicated field and start the scan. Wait for the short amount of time for the real-time scan to check for potentially harmful items.

How to check if a secure site via browser

Another guarantee that a secure site has a SSL certificate, that's exactly what it is, don't worry all very simple to understand.

A SSL certificate (Secure Sockets Layer) a standard protocol that protects communications via the Internet, so as to ensure that sensitive information provided by users on the web (such as passwords, personal data and credit card numbers) remain confidential and are not in no way intercepted by third parties.

To do this the communication between the client server and the web server encrypted. To understand if we navigate with a connection that is based on SSL certificate / protocol is enough look at the address on the navigation bar. In our browser where we will see a padlock and instead of http: // we will find https: // we will know that we are on a site that uses SSL certificates. This guarantee protects against fraud and theft, especially important if you are dealing with e-commerce sites and for all those sites that provide online services with the exchange of sensitive and private data.

Below you can see, in the main internet browsers, how to see if a site uses a secure and encrypted connection.
