What is the best action that a company should take when a mobile device is lost with an active network connection and a copy of unencrypted confidential data on the device?

lock the phone
encrypt the data
wipe the data
locate the phone

In such a situation, the best action for a company to take would be to:

1. Lock the phone: The first step should be to lock the lost mobile device remotely to prevent unauthorized access. This ensures that even if someone finds the device, they won't be able to use it or access the data without the necessary credentials.

2. Wipe the data: If the confidential data on the device is unencrypted, it poses a significant security risk. To mitigate this risk, the company should immediately initiate a remote data wipe to erase all the data on the device. This helps prevent any unauthorized access or misuse of the confidential information.

3. Encrypt the data: For future instances, it is crucial to ensure that all confidential data stored on mobile devices is properly encrypted. Encryption provides an additional layer of security, making it extremely difficult for unauthorized individuals to access and decipher the information even if the device is lost or stolen.

4. Locate the phone: While locking, wiping, and encrypting the data are important steps to secure the information, locating the physical device can also be useful. Companies can use location tracking services or applications to identify the whereabouts of the lost phone. This information can be beneficial for potential recovery or investigations if required.

By taking these actions, the company can effectively protect the confidential data, minimize potential harm, ensure compliance with data protection regulations, and maintain the trust of their customers and stakeholders.
