Protect your network with Li-Fi!
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.

LiFi and Healthcare
Through the National Plan of Resilience and Recovery (PNRR), the Italian government explained how it will invest European resources provided by the Recovery Fund: among several fields, the healthcare sector was particularly emphasized. A significant part of the resources will be allocated to healthcare to digitalize medical care.
Among several technological innovations in the medical field, LiFi joins the picture along with the transparent photovoltaic glass windows, which are relevant for sustainable purposes.
Applications in the healthcare field can be as beneficial for patients as they are for healthcare workers and visitors. The implementation of specific LiFi Zones can bring several services that aim at improving the check-in and check-out processes, as well as geo-locating and sharing medical records. This would guarantee the privacy and safety of the data transmission.
It is important to keep in mind that many medical devices that are used in the surgical room, both in intensive therapy and in radiology, do not allow radio frequencies, therefore the WiFi. This makes LiFi technology a valid alternative to WiFi in the medical field. Since it emits a signal that does not interfere with the medical equipment, the LiFi technology allows a bidirectional and wireless connection which guarantees fast data transmission, high bandwidth, and density.
How Does it Work?
Every device comes equipped with a modem that modulates light at a rate that is not perceptible by the human eye. This process is detected by a USB Li-Fi key that is connected to a computer or a tablet. This USB Li-Fi key then transmits the data to the lighting device through an infrared connection. In addition, LiFi guarantees higher cybersecurity, because light cannot penetrate solid barriers such as walls. Thus, direct exposure to light is necessary to access the network.
Digital Threats: LiFi’s Answer to Hacker Attacks
Connect one or more computers to the internet extremely fast without the risk of external hacker attacks.
How important is cybersecurity to the digital transformation process?
According to a study conducted by Cybersecurity Ventures, cybercrime will leave a significant impact within 2025: an amount of about 10 trillion dollars will go to fight cybercrime, an annual increase of 15%. This data is concerning for many companies, that find themselves having to implement several costly security measures to counter the increasing external hacker attacks.
To meet companies’ needs, LiFi S would represent an ideal solution to significantly reduce cybercrime. It is a wireless system that provides a fast, safe, and sustainable connection, that can reach a speed of 1 Gbps without emitting radio waves. Thus, this system is free from electromagnetic pollution, external hacker attacks, and interference problems.
How Does it Work?
The main innovative characteristic of this technology lies in data transmission through light wave modulation, thus offering benefits such as high-speed, large bandwidth, security, and sustainability. A LiFi S installation can transmit and receive data at a very fast rate, without issues of band saturation, signal interception, or electromagnetic pollution because of radio waves.
Taking all these benefits into account, it can be stated that LiFi S is the ideal solution to the corporate world’s needs, where cybersecurity must be elevated and the number of devices having access to the network must be well defined. This technology would offer a connection whose speed and quality are unprecedented. Converting light sources into hotspots that collect and transmit data is, therefore, the best option to guarantee security and privacy in work activities.
