Explanation
Endpoint encryption is a security practice that transforms the data stored on a laptop or other device into an unreadable format using a secret key or algorithm. Endpoint encryption protects the privacy of data in case of loss or theft, by ensuring that only authorized parties can access and use the data, while unauthorized parties cannot decipher or modify the data without the key or algorithm. Endpoint encryption also helps to comply with data protection laws and regulations, such as the General Data Protection Regulation (GDPR) or the California Consumer Privacy Act (CCPA), which require data controllers and processors to implement appropriate technical and organizational measures to safeguard personal data.
The other options are less effective or irrelevant for protecting the privacy of data stored on a laptop in case of loss or theft. Strong authentication controls, such as passwords, biometrics or multifactor authentication, are important for verifying the identity and access rights of users, but they do not protect the data from being accessed by bypassing or breaking the authentication mechanisms. Remote wipe is a feature that allows users or administrators to erase the data on a lost or stolen device remotely, but it depends on the availability of network connection and device power, and it may not prevent data recovery by sophisticated tools. Regular backups are a process of creating copies of data for recovery purposes, such as in case of data loss or corruption, but they do not protect the data from being accessed by unauthorized parties who may obtain the backup media or files.
