An administrator would like to encrypt the communication between servers and the target in an iSCSI SAN. Which of the following would accomplish this?

A TPM (Trusted Platform Module) is a hardware security component used for secure key storage and system integrity verification, not for encrypting network communication.

IPSec (Internet Protocol Security) is a suite of protocols used to provide secure communication over an IP network by authenticating and encrypting each IP packet. When configured for iSCSI, IPSec encrypts the data payloads of iSCSI packets as they travel between the initiator and the target, ensuring confidentiality.

EFS (Encrypting File System) is a feature that encrypts files at the file system level on local storage, not for encrypting data in transit over a network.

CHAP (Challenge-Handshake Authentication Protocol) is used for authenticating the iSCSI initiator to the target, verifying identity, but it does not encrypt the actual data traffic.
