Enrique is concerned about backup data being infected by malware. The company backs up key servers to digital storage on a backup server. Which of the following would be most effective in preventing the backup data being infected by malware?

Air gapping refers to the server not being on a network. This means literally that there is "air" between the server and the network. This prevents malware from infecting the backup server. A separate virtual local area network (VLAN) or physical network segment can enhance security but is not as effective as air gapping. A honeynet is used to detect attacks against a network, but it doesn't provide effective defense against malware in this scenario.
