Data Hacks Demonstrate IT Networks’ Need for Optical Protections

Facebook X LinkedIn Email
Information technology computer scientists at Karlsruhe Institute of Technology (KIT) have demonstrated how data can be transmitted to LEDs — contained in regular office devices such as a printer — using a directed laser. The demonstration shows the ability for data hackers to secretly communicate with “air-gapped” computer systems over distances of several meters. According to the team, this shows that in addition to conventional information and communication technology security, critical IT systems must also be protected optically. The collaborative work...Read full article
