セキュリティ コンサルタントは、クライアント環境への安全なリモート アクセスを必要とします。セキュリティ コンサルタントがアクセスするために使用する可能性が高いのは次のうちどれですか。
正解:C
IPSec is a protocol suite that provides secure communication over IP networks. IPSec can be used to create virtual private networks (VPNs) that encrypt and authenticate the data exchanged between two or more parties. IPSec can also provide data integrity, confidentiality, replay protection, and access control. A security consultant can use IPSec to gain secure, remote access to a client environment by establishing a VPN tunnel with the client's network.
