When tasked with enhancing the ongoing security of an organization's distributed workforce's devices, which of the following is the MOST effective approach?
Perform a quarterly vulnerability scan to identify and resolve security risks on all distributed workforce’s devices.
Reset all user account passwords biannually to ensure the security of device access.
Implement regular updates to the policies governing device management to address new security threats and compliance requirements.
Restrict application installations exclusively to apps from the approved corporate app store.
