SSCP Network and Communications Security Practice Question

Which protocol is used for secure web browsing and operates on TCP port 443?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

HTTPS

HTTPS (HTTP over TLS) uses TCP port 443 and provides encrypted communication for websites.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✓

    HTTPS

    Why this is correct

    HTTPS wraps HTTP inside TLS, encrypting web traffic and authenticating the server, and by convention listens on TCP port 443. That combination delivers the confidentiality and integrity required for secure browsing over the specified port.

  • ✗

    HTTP

    Why it's wrong here

    HTTP serves web content on TCP port 80 without encryption, so it fails the secure browsing requirement on 443. It is tempting because HTTP is the web protocol, and it would be correct for plain, non-sensitive intranet pages where TLS is not mandated.

  • ✗

    SSH

    Why it's wrong here

    SSH provides encrypted remote shell access on TCP port 22, not web browsing on 443. It is tempting because SSH also uses TLS-like encryption, and it would be correct for secure command-line administration or SFTP file transfer between hosts.

  • ✗

    FTP

    Why it's wrong here

    FTP transfers files over TCP ports 20 and 21 and provides no transport encryption, so it cannot serve HTTPS on 443. It is tempting because FTP also moves data between hosts, and it would be correct for bulk file transfer where confidentiality is not required.
