HTTPS / SSL - encrypted web traffic.
Call of Duty World at War uses this port.
Port also used by some trojans:
W32.Kelvir.M (04.05.2005) - worm that spreads through MSN Messanger and drops a variant of the W32.Spybot.Worm. Connects to IRC servers on the s.defonic2.net and s.majesticwin.com domains, and listens for commands on port 443/tcp.
Some Apple applications use this port as well: Secured websites, iTunes Store, FaceTime, MobileMe (authentication and MobileMe Sync.
Directory traversal vulnerability in Cisco Network Admission Control (NAC) Manager 4.8.x allows remote attackers to read arbitrary files via crafted traffic to TCP port 443, aka Bug ID CSCtq10755.
References: [CVE-2011-3305] [BID-49954]
Multiple buffer overflows in the authentication functionality in the web-server module in Cisco CiscoWorks Common Services before 4.0 allow remote attackers to execute arbitrary code via a session on TCP port (1) 443 or (2) 1741, aka Bug ID CSCti41352.
References: [CVE-2010-3036] [BID-44468] [SECUNIA-42011] [OSVDB-68927]
Buffer overflow in the logging functionality of the HTTP server in IBM Tivoli Provisioning Manager for OS Deployment (TPMfOSD) before 5.1.0.3 Interim Fix 3 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via an HTTP request with a long method string to port 443/tcp.
References: [CVE-2008-0401] [BID-27387] [SECUNIA-28604]
The administrative web interface on Cisco TelePresence Immersive Endpoint Devices before 1.7.4 allows remote authenticated users to execute arbitrary commands via a malformed request on TCP port 443, aka Bug ID CSCtn99724.

TCP ports use the Transmission Control Protocol. TCP is the most commonly used protocol
on the Internet and any TCP/IP network. Whereas the IP protocol deals only with packets, TCP enables two hosts
to establish a connection and exchange streams of data. TCP guarantees delivery of data
and that packets will be delivered in the same order in which they were sent.
Guaranteed communication/delivery is the key difference between TCP and UDP.
UDP ports use the Datagram Protocol, a communications protocol for the Internet network,
transport, and session layers. Like TCP (Transmission Control Protocol),
UDP is used with IP (the Internet Protocol) and makes possible the transmission of datagrams
from one computer to applications on another computer, but unlike TCP, UDP is connectionless
and does not guarantee reliable communication; it's up to the application that received
the message to process any errors and verify correct delivery. UDP is often used with time-sensitive
applications, such as audio/video streaming, where dropping some packets is preferable to waiting for delayed data.
