What is SMB, What is SMB Port Numbers 135 and 445, SMB is a networking protocol that allows systems on a network to share access. This article is all about SMB, how it works and what ports it uses.
An SMB port is a network port commonly used for file sharing that is susceptible to an exploit known as EternalBlue exploit that resulted in WannaCry.
Open ports can be dangerous when the service listening on the port is misconfigured, unpatched, vulnerable to exploits, or has poor network security rules. Of particular danger are wormable ports which are open by default on some operating systems, such as the SMB protocol which was exploited ...

SMB over QUIC is an alternative to TCP and RDMA that supplies secure connectivity to edge file servers over untrusted networks. Client access control introduces more controls to restrict access to your data by using certificates. To learn more, see How client access control works....
The final section of the ICMP packet is the original datagram. It consists of up to 576 bytes in IPv4 and 1,280 bytes in IPv6 and includes a copy of the original error-containing IP message. The ICMP packet header is followed by the pointer, which identifies the problem in the original...
