CERT-FR recommends completely deactivate Wi-Fi whenever it’s not in use
Source Reddit InfoSec News
Description
CERT-FR has issued a recommendation to completely deactivate Wi-Fi whenever it is not in use to reduce attack surfaces and prevent potential unauthorized access. This advisory highlights the risks associated with leaving Wi-Fi enabled unnecessarily, which can expose devices and networks to various wireless attacks such as unauthorized access, man-in-the-middle, and exploitation of Wi-Fi protocol vulnerabilities. Although no specific vulnerability or exploit is detailed, the guidance aims to mitigate risks by minimizing wireless exposure. European organizations, especially those with sensitive data or critical infrastructure, should consider this practice to enhance their security posture. The recommendation is particularly relevant for environments where Wi-Fi is not continuously needed, such as offices after hours or industrial settings. Countries with high adoption of Wi-Fi-enabled devices and critical infrastructure reliant on wireless connectivity are more likely to benefit from this advice. Given the medium severity rating and lack of known exploits, the threat is more about reducing risk exposure than responding to an active exploit. Practical mitigation includes disabling Wi-Fi radios when idle, enforcing strict network access controls, and monitoring for unauthorized wireless activity. This advisory serves as a reminder that wireless interfaces represent a persistent attack vector and should be managed proactively to reduce potential compromise.
