Palo Alto Networks Certified Cybersecurity Entry-level Technician (PCCET)Network SecurityEasy

A cybersecurity team is deploying a new web application that will handle sensitive customer data. They need to ensure the highest level of data integrity and confidentiality during transmission between the client's browser and the web server. Which cryptographic protocol should be primarily used to secure this communication?

  1. ASNMP (Simple Network Management Protocol)
  2. BFTP (File Transfer Protocol)
  3. CTLS (Transport Layer Security)
  4. DSMTP (Simple Mail Transfer Protocol)
Show answer & explanation

Correct answer: C. TLS (Transport Layer Security)

TLS is the standard cryptographic protocol used to secure communications over computer networks, particularly for web browsing (HTTPS), providing both confidentiality and integrity for sensitive data transmitted between a client and a server.

Why the other options are wrong

  • A. SNMP is for network device management and is not used for securing web application data transmission.
  • B. FTP is for file transfer and is inherently insecure; it does not provide encryption unless SFTP or FTPS is used.
  • D. SMTP is for sending email and does not provide end-to-end encryption for general web application communication.

Transport Layer Security (TLS)

A cryptographic protocol designed to provide communication security over a computer network.

  • Successor to Secure Sockets Layer (SSL).
  • Used to secure web traffic (HTTPS), email, VPNs, and other data-in-transit.
  • Provides authentication, confidentiality (encryption), and integrity.

Memory trick: Different protocols secure different types of conversations.
