A company has just experienced a data breach that affected all mobile devices. Which of the following would BEST secure access to user's mobile devices? (Choose two.)

Question

Options

• AFull device encryption
• BRemote backup application
• CSSO authentication
• DDevice profiles update
• EOS security updates
• FBiometric authentication

• A
  74% (17)
• B
  13% (3)
• D
  9% (2)
• E
  4% (1)

Explanation

Full device encryption (A) protects all data stored on a mobile device so that even if the device is physically stolen or accessed without authorization, the data remains unreadable without the decryption key. Biometric authentication (F) - such as fingerprint or facial recognition - provides strong, hardware-level identity verification that is difficult to replicate or steal, directly securing the access control layer. Together, these two controls address both data-at-rest protection and robust authentication. The other options are less directly tied to securing device access: remote backup (B) protects data copies but doesn't secure access; SSO (C) centralizes authentication but doesn't add mobile-specific security; device profile updates (D) manage configuration but don't inherently secure access after a breach; and OS security updates (E), while important, are a preventive measure rather than an immediate access-security control.
