Emiliana is a network administrator and is concerned about the security of peripheral devices. Which of the following would be a basic step she could take to improve security for those devices?

The correct answer is to turn off any remote access to such devices that is not absolutely needed. Many peripheral devices come with SSH (Secure Shell), Telnet, or similar services. If you are not using them, turn them off. Many peripherals don’t have disks to encrypt, making full-disk encryption (FDE) a less useful choice. Fuzz testing is used to test code, not devices, and peripherals are unlikely to support digital certificates in most cases.
