Once the payload is run, the netcat session from earlier will respond. The dialect to follow, SMB 2.0, improved the protocol's efficiency by drastically reducing its hundreds of commands and subcommands down to just 19. In the OSI model, communication between separate computers occurs in a stack-like fashion with information passing from one node to the other through several layers of code, including: Physical layer. It can also carry transaction protocols for inter-process communication. Server Message Block is a network communication transfer protocol to provide shared access to files, printers, ports between the networks. However, for communication to work between individual components, clear conventions are required provided in the form of protocols. Today, CIFS is particularly common as a term for the first SMB version 1.0. We explore it in detail in this article. It's also referred to as the server/client protocol, as the server has a resource that it can share with the client. Throughout that time, SMB has been widely implemented and continues to be one of the most popular solutions for file sharing in the workplace. With the upgrades of its versions, the services are much more enhanced and effective to use by the users or clients. To establish a connection between a client and a server using Microsoft SMB Protocol, you must first determine the dialect with the highest level of functionality that both the client and server support.
