OTA
Over-the-Air
Wireless delivery of updates or configuration to devices.
Over-the-Air describes the wireless delivery of software updates, firmware, or configuration to devices such as smartphones, IoT endpoints, and vehicles. It enables rapid, large-scale patching without physical access, which is valuable for fixing vulnerabilities quickly. The same channel is a risk if updates are not authenticated and integrity-protected, since attackers could push malicious firmware or intercept the process. Signed update packages and secure transport are essential controls, and mobile device management often coordinates OTA deployment in enterprises.
Looking OTA up is step one. Getting tested on it is step two.
