The PostgreSQL database service is available on localhost and the default PostgreSQL port is 5432 .Default port: 5432, and if this port is already in use it seems that postgresql will use the next port (5433 probably) which is not in use.By default, PostgreSQL uses port number 5432. However, you may have changed the port number during installation or configuration. You can find the port number in the PostgreSQL configuration file, 'pg_hba.
What port does Postgres use standard : PostgreSQL, an open-source object-relational database management system, relies on a default port for communication purposes. By default, PostgreSQL uses port 5432 for TCP/IP connections. This port is designated for both client-server communication and inter-server communication within a Postgres cluster.
Is port 5432 Secure
PostgreSQL – 5432 is used by SQL server to listen for client requests. Allowing inbound traffic from all external IP addresses on PostgreSQL port is vulnerable to postgresql exploit. It is a best practice to block public access, and restrict access from specific IP addresses to port 5432.
What port can I use instead of 5432 : In PostgreSQL's case it's typical to use port 5432 if it is available. If it isn't, most installers will choose the next free port, usually 5433. You can see what is actually running using the netstat tool (available on OS X, Windows, and Linux, with command line syntax varying across all three).

It is a best practice to block public access, and restrict access from specific IP addresses to port 5432. How to figure out if PostgreSQL database is running
Check if PostgreSQL is listening on port 5432: [11:20]root@onms:~# ss -tulpn | grep 5432 tcp LISTEN 0 128 :::5432 :::* users:(("docker-proxy",pid=26410,fd=4))
Check systemd status.
Check if connection to PostgreSQL database is working.
Is port 1433 vulnerable
Several vulnerabilities come with using port 1433. These include injection attacks, which can lead to data breaches if not adequately mitigated. Like other database ports, including 1434 and 3306, these are frequently targeted by attackers for the distribution of malware, or as direct targets in DDoS attacks.Is port 8080 vulnerable Like port 443, port 8080 is also vulnerable to SQL injections, cross-site scripting, DDoS attacks, and cross-site request forgery.The highest TCP port number is 65,535. The TCP protocol provides 16 bits for the port number, and this is interpreted as an unsigned integer; all values are valid, apart from 0, and so the largest port number is (2^16 – 1) or 65,535. TCP port
The TCP port the server listens on; 5432 by default. Note that the same port number is used for all IP addresses the server listens on. This parameter can only be set at server start.
Is port 8443 a vulnerability : Ports 80, 443, 8080 and 8443 (HTTP and HTTPS)
They're especially vulnerable to cross-site scripting, SQL injections, cross-site request forgeries and DDoS attacks.
Can port 80 be hacked : It is obvious that such a server could be easily hacked by any client which can reach the server – no matter if the client connects to port 80 with plain HTTP, port 443 with encrypted HTTPS, port 25 (mail), …
Why is port 22 risky
Port 22 is associated with the SSH (Secure Shell) protocol, which is used to securely connect to a remote device and issue commands just like you would on your own device. This default port does have its vulnerabilities, though: port 22 a popular target for brute force attacks and unauthorized access attempts. Ports with numbers 0–1023 are called system or well-known ports; ports with numbers 1024-49151 are called user or registered ports, and ports with numbers 49152-65535 are called dynamic, private or ephemeral ports.If the database port number is set to 5439, the selected Amazon Redshift cluster is not using a non-default port for database access, therefore is vulnerable to brute-force and dictionary attacks.
Why use port 8443 instead of 443 : The key difference between HTTPS port 443 and port 8443 is that Apache Tomcat uses 8443 to open SSL text service to avoid conflicts, whereas 443 is a web browsing port meant to secure data transmission between web browsers and servers.
