Between attackers and defenders, who is in the lead? In cybersecurity, the attackers have long been viewed as the default winners. Yet infrastructures are becoming better and better at protecting themselves. Although much remains to be done, things are not as imbalanced as they might seem, and research is providing valid cyberdefense solutions to help ensure the security and resilience …

Viruses, malware, spyware and other digital pathologies are not the only way computer systems’ vulnerabilities are exploited. Hardware attacks are not as well-known as these software attacks, but they are just as dangerous. They involve directly exploiting interaction with a system’s electronic components. These sneak attacks are particularly effective against connected objects. Jean-Max Dutertre’s team at Mines Saint-Étienne is committed …
