A technician needs to send a new employee's contract, which contains Personally Identifiable Information (PII), to the HR department via email. Which of the following is the BEST method to ensure the confidentiality of this sensitive data during transit?
Save the contract on a public file-sharing site and email the link.
Include all the sensitive details directly in the email's subject line for clarity.
Encrypt the email before sending it.
Send the contract as a password-protected file attachment.
Using encryption is the best practice for securing sensitive email content during transit. Encryption transforms the message into a format that is unreadable to unauthorized parties who might intercept it. While sending a password-protected file is a form of protection, encrypting the entire email provides a more comprehensive security layer. Sending information in plain text or including it in the subject line are insecure practices that expose sensitive data to risk.
