Safe Browsing: One of the most important and discussed issues of recent years. A trend that over time will be increasingly significant. 

Li-Fi and security. The most well-known hacker attacks include ransomware and password attacks. In the first case it is a malware stealing personal data and asking for a ransom to get the data back. This type of attack is the one that hit the Lazio Region in August 2021. The second type of hacking mentioned, however, aims to subtract the credentials of access to our digital life. The two most frequently used password cracking techniques are: social engineering, using email or fishing messages convinces the user to communicate their password, and credential stuffing, you hack the database of a service containing a large number of user passwords and try them on other sites. In the latter case, famous is the episode that hit LinkedIn in 2012 when about 164 million credentials were stolen and were put on sale in 2016.     It’s interesting to notice how even Wi-Fi, the most widely used technology today, can be so vulnerable. How is that possible? Let’s look at the technique called DNS (Domain Name Server) hijacking, through which hackers enter a network without the owners realizing it. It is a technique that allows users to be redirected to websites specifically designed to infect computers or induce victims to reveal sensitive data. In particular, the router hijack variant can put our Wi-Fi network at risk: very few users, in fact, have the foresight to change the credentials of their routers and the standard ones, usually, are predefined and identical for all devices sold. It’s easy for hackers to retrieve credentials, access your router, and redirect our searches to unsafe websites.  

Why is Li-Fi a safe technology?

LiFi is, to date, one of the safest technologies for data transmission because instead of using radio frequencies as a connecting vehicle, it uses infrared and visible light spectrum. All waves that are not able to overcome physical barriers: the network becomes invisible for those outside the light beam of LED lamps.     By installing LiFi solutions, a hacker to connect to the network should be physically present within the room. One can also create localized network offices that allow access only to some departments and not to others. All that said, it makes clear that Li-Fi can be really a great ally to surf the net safely.
