Focus on memorization of port numbers for CompTIA A+, understand their standardization, and note this course covers port numbers only, not the entire A+ exam.
Explore how FTP uses port 20 for data transfer and port 21 for commands within a client-server model, emphasizing why both ports must be open for non-secure transfers.
Master port 22 and ssh, the secure shell for encrypted remote access that bypasses firewalls and reduces man-in-the-middle risk. Use two keys, two devices, and connections for auth and session.
Explore telnet (port 23) as a plain text protocol lacking encryption, exposing passwords; learn its legacy and use in pentesting alongside other transfer protocols like ftp (20–21) and ssh (22).
Master the simple mail transfer protocol ports 25, 465, and 587: 25 is the oldest and vulnerable, 465 uses ssl but deprecated, and 587 is the modern secure option.
Learn port 110 and the POP3 protocol, which downloads emails from the server to the client, deletes them, and uses an unencrypted legacy standard.
Learn how imap port 143 retrieves emails over tcp/ip, using internet message access protocol to keep messages on the server and supported by major clients.
Discover port 443 as the secure counterpart to http port 80, with https encrypted by ssl and tls on modern commercial sites.
