With which technology do apply integrity, confidentially and authenticate the source
A.
IPSec
B.
IKE
C.
Certificate authority
D.
Data encryption standards
Explanation:
IPsec is a collection of protocols and algorithms used to protect IP packets at Layer 3 (hence
the name of IP Security [IPsec]). IPsec provides the core benefits of confidentiality through
encryption, data integrity through hashing and HMAC, and authentication using digital
signatures or using a pre-shared key (PSK) that is just for the authentication, similar to a
password.
