Is port 1025 Safe?
TCP is one of the main protocols in TCP/IP networks. UDP port 1025 would not have guaranteed communication in the same way as TCP. Because protocol TCP port 1025 was flagged as a virus (colored red) does not mean that a virus is using port 1025, but that a Trojan or Virus has used this port in the past to communicate.
Are open ports a security risk?
Open ports can be dangerous when the service listening on the port is misconfigured, unpatched, vulnerable to exploits, or has poor network security rules. The reason people call for closed ports because less open ports reduces your attack surface.
Is there an official port 465 for SMTP?
Interestingly, port 465 was never published as an official SMTP transmission or submission channel by the IETF. Instead, the Internet Assigned Numbers Authority (IANA), who maintains much of the core internet infrastructure, registered port 465 for SMTPS.
What are ports 445 and 139 used for?
Ports 445 and 139 Explained The Server Message Block Protocol (SMB Protocol) is a client-server communication protocol used for sharing access to files, printers, serial ports, and data on a network. It can also carry transaction protocols for authenticated inter-process communication.
Why does SMB still use port 445 and 139?
SMB still uses port 445. This proved to be problematic as CIFS was a notoriously chatty protocol that could ruin network performance due to latency and numerous acknowledgments. While Microsoft estimates that SMB/CIFS compromised less than 10% of network traffic in the average Enterprise network, that is still a significant amount of traffic.
Is there a Port 2525 or 587 for SMTP?
Instead, Mailgun provides it as an alternate port, which mirrors port 587, in the event the above ports are blocked. Because 2525 is a non-traditional high port number, it is typically allowed on consumer ISPs and Cloud Hosting providers, like Google Compute Engine.
