What uses port 5433?
Network Time Protocol (NTP. NTP is a protocol for synchronizing the clocks of computers over a network.) Ensure port 5433 is open in order to access the Insight database. Port 5433 is also used for connecting to the tipsLogDb.TCP port 5432 is used by the PostgreSQL Database Server, an object-relational database management system (RDBMS) server developed by PostgreSQL Global Development Group. This rule resolution is part of the Conformity Security & Compliance tool for Azure.port 53

The standard port for DNS is port 53. DNS client applications use the DNS protocol to query and request information from DNS servers, and the server returns the results to the client using the same port. Port 53 is used for both TCP and UDP communication.

What service runs on port 143 : IMAP server

An IMAP server typically listens on port number 143. IMAP over SSL/TLS (IMAPS) is assigned the port number 993. Virtually all modern e-mail clients and servers support IMAP, which along with the earlier POP3 (Post Office Protocol) are the two most prevalent standard protocols for email retrieval.

Is PostgreSQL port 5432 or 5433

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.

What is the default port for PostgreSQL 5433 : PostgreSQL, by default, listens on port 5432 . There might be scenarios where you need to change this default port due to conflicts, security concerns, or other reasons.

Port 53 is used by DNS (Domain Name System). DNS takes care of recolving human readable 'host names' into numeric IP addresses.

With DNS over HTTPS (DoH), DNS queries and responses are encrypted and sent via the HTTP or HTTP/2 protocols. DoH ensures that attackers cannot forge or alter DNS traffic. DoH uses port 443, which is the standard HTTPS traffic port, to wrap the DNS query in an HTTPS request.

Is port 143 vulnerable

The bad news is that some of these programs cause this port to be opened and exposed to the outside world — to the whole Internet — which can create serious vulnerabilities for the user's PC.143 – this is the default port which does not provide any encryption. Port 993 is the secure port for IMAP and it works over TLS/SSL encryption.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.

port 5432

By default, the Postgresql database listens on port 5432. If you want to change this port, you must edit the PGPORT environment variable in /etc/rc.

Is port 53 vulnerable : Vulnerabilities in DNS Bypass Firewall Rules (UDP 53) is a Low risk vulnerability that is one of the most frequently found on networks around the world. This issue has been around since at least 1990 but has proven either difficult to detect, difficult to resolve or prone to being overlooked entirely.

Is port 53 safe : UDP port 53 is used by the DNS protocol to resolve domain names to IP addresses and vice versa. If it is left open and unrestricted, it can be exploited by attackers to redirect users to malicious websites, intercept sensitive information or launch DDoS attacks.

Why is port 443 special

In other words, this browser-dedicated port encrypts data by converting it to an algorithm. Then, port 443 converts the algorithm to the ciphertext to send them to the server to prevent any possible privacy leak. That way, port 443 provides a secure channel for the browser and server to communicate and transfer data.

As we mentioned earlier, port 443 is part of the HTTPS protocol, being one of the paths that allow access to data packets. This port is vulnerable to SQL injections, cross-site scripting, DDoS attacks, and cross-site request forgery.High Risk Ports are typically associated with remote access to data and user interfaces. These services include databases, file sharing protocols (FTP and SMB), and remote access tools (Telnet, SSH, RDP, and VNC).

Is port 143 encrypted : IMAP ports

143 – this is the default port which does not provide any encryption. Port 993 is the secure port for IMAP and it works over TLS/SSL encryption.
