You work as a Security Manager for Tech Perfect Inc. You find that some applications have failed to encrypt network traffic while ensuring secure communications in the organization. Which of the…

SCP (Secure Copy Protocol) is a network protocol that supports file transfers between hosts on a network, leveraging SSH for security, but it's for file transfer, not a general solution for all application traffic encryption.

Transport Layer Security (TLS) is a cryptographic protocol designed to provide communication security over a computer network. It is widely used to encrypt data in transit for many applications, including web browsing (HTTPS), email (SMTPS, IMAPS, POP3S), and other client-server communications, thereby ensuring secure communications and resolving issues with unencrypted traffic.

IPSec (Internet Protocol Security) is a suite of protocols for securing IP communications by authenticating and encrypting each IP packet, but TLS is more commonly used at the application layer to secure specific application traffic without requiring network-wide tunnel or transport mode configurations.

HTTPS is HTTP over TLS/SSL; it's an application-layer protocol for secure web browsing, not a general protocol to secure any application's network traffic directly, as TLS is the underlying mechanism.
