Which practice will not assist an incident responder in eradicating mobile-based security incidents?

Disabling lost device tracking service will not assist an incident responder in eradicating mobile-based security incidents because this service is designed to help locate and potentially recover lost or stolen devices. By disabling it, the risk of losing valuable data and the ability to respond effectively in case of a security incident increases. In the context of mobile security incidents, keeping tracking services enabled can aid in preventing data breaches and unauthorized access to sensitive information that may be on the device.

On the other hand, the other practices listed are proactive measures that can help mitigate security risks. Disabling biometric authentication may introduce vulnerabilities in device access, while clearing device caches regularly can help remove potentially sensitive data that could be exploited. Updating all installed applications ensures that known vulnerabilities are patched, making it a critical step in maintaining security on mobile devices.
