A law firm wants to ensure that all communications between its employees and its email server are secure from interception. Which encryption protocol should the firm implement to protect email transmissions over the network?
WPA2
SMTP
TLS
SSH
Transport Layer Security (TLS) is the appropriate protocol for securing data in transit, including email communications. TLS encrypts the connection between the email client and server, preventing unauthorized access. Secure Shell (SSH) is typically used for secure remote access, WPA2 secures wireless networks, and Simple Mail Transfer Protocol (SMTP) by itself does not provide encryption.
