What is port 443 for?

Port 443 is the web browsing port, which is mainly used for HTTPS services, and its function is to provide secure Internet protocols so as to ensure the security of customers.

Banks generally use port 443, the purpose of which is to ensure the security of customers' funds and, secondly, the security of transactions.

Therefore, port 443 is widely used in our daily life, and many websites that need to trade money online will use port 443 to ensure security.

443 port function

1. Provide services to others

Someone once compared a server to a house and a port to a door to different rooms (services), which is a good metaphor without considering the details. If the intruder wants to occupy the house, he is bound to break into the house (another physical invasion), so it is very important for the intruder to know how many doors the house has opened, what kind of door is open, and what is behind the door.

2. Ensure the security of customer transactions.

Intruders usually use scanners to scan the ports of the target host to determine which ports are open. From the open ports, the intruder can know what services the target host provides, and then guess the possible loopholes. Therefore, port scanning can help us better understand the target host, and for administrators, scanning the local open port is also the first step in security precautions.

Although port 443 is guaranteed for our online transactions, we can't take it lightly. Port 443 is open for system services, but hackers will use other ports to invade, so please check which ports are open on your computer before trading, and then turn off the unwanted ones, so as to further ensure the security of your transaction. What the editor would like to remind you is that when trading on the Internet, we must not click on those websites of unknown origin. The website of the transaction must be a relatively large website, and it will not give us a private URL, so we should pay special attention to it.
