Port 443 and Port 8443 used for two that are frequently mentioned ports. Effective configuration and network service security can be achieved by being aware of their roles and distinctions.
What does port 443 mean?
The typical port for HTTPS transmission is 443. It offers a safe channel for the transmission of encrypted data between a client browser and a web server. For sensitive transactions like online banking, e-commerce, and other secure connections, this port is essential.
Main Use: Web servers use port 443 to enable safe communication between a browser and the server. It uses the SSL/TLS protocols to guarantee the integrity and encryption of data.
Setup: Usually, in order to configure Port 443, you must:
Include Rules for Firewalls: Create rules in your firewall to permit communication over port 443.
Apply and Save: Verify that the rules are saved and given priority in your firewall configuration.
What does Port 8443 mean?
They often use port 8443 to prevent conflicts with services running on port 443 or to provide secure connections in development settings.
Main Use: Tomcat, a well-known Java Servlet container, usually uses port 8443 for SSL/TLS connections.Tomcat servers can manage HTTPS traffic, which developers frequently use in staging or development settings.
Configuration: The server’s configuration files in Tomcat are where you set up 8443 port. Important configurations consist of:
Configuring SSL:
<Connector port=”8443″ protocol=”HTTP/1.1″
maxThreads=”150″ scheme=”https” secure=”true”
clientAuth=”false” sslProtocol=”TLS”
keystoreFile=”/path/to/keystore” keystorePass=”yourpassword”/>
Particular Port: Port 8443 differs from Port 443 in that the port number needs to be specified in the URL
Important Distinctions Between Port 8443 and Port 443 Usage:
The internet uses port 443, the standard port for HTTPS, for secure web communication. Applications like Tomcat frequently use port 8443 for HTTPS.
Use this port in non-production situations or if port 443 is already in use. Port 443 can access without the need for port number, is the equivalent of http 80. It can directly access through the domain name.
Example: https://domainname.com
Setup: The majority of web servers have port 443 configured as the standard HTTPS port.
