Cisco WaaS Central Manager standard SSL administration port.
German Health Getwork (aka Gesundheitskarte) "Konnektor" uses ports 8443 and 9443.
Symantec Endpoint Protection Manager could allow a remote attacker to obtain sensitive information, caused by an XML External Entity Injection (XXE) error within the SAP XML parser when processing XML data. By sending a specially-crafted request to TCP port 8443, an attacker could exploit this vulnerability to read arbitrary files and obtain sensitive information.

Symantec Backup Exec System Recovery Manager could allow a remote attacker to upload arbitrary files, caused by an error in the FileUpload Class running on the Symantec LiveState Apache Tomcat server. A remote attacker could exploit this vulnerability using an HTTP POST request over port 8443 (TCP) to upload arbitrary files, which could allow the attacker to execute arbitrary code on the vulnerable system with SYSTEM privileges.

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.
When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them.
This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command.
We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software.
