Server Message Block
Field Of Study- In computer networking, Server Message Block, one version of which was also known as Common Internet File System, is a network communication protocol for providing shared access to files, printers, and serial ports between nodes on a network. It also provides an authenticated inter-process communication mechanism. Most usage of SMB involves computers running Microsof…
- Over the years, there have been many security vulnerabilities in Microsoft's implementation of the protocol or components on which it directly relies. Other vendors' security vulnerabilities lie primarily in a lack of support for newer authentication protocols like NTLMv2 and Kerberos in favor of protocols like NTLMv1, LanMan, or plaintext passwords. Real-time attack tracking show…
- SMB2 was designed for more secure user access to files and applications with greater efficiency and performance in WANs and large LANs than earlier versions of the protocol. SMB3 was developed for block infrastructure workloads operating at modern data center scale over remote direct memory access networks, plus highly secure file access scenarios.
- CIFS was designed to not only provide clients with managed, concurrent access to files and directories hosted on server systems, but to facilitate access to print queues and interprocess communication services over a network. By contrast, NFS restricted its domain to file sharing.

Barry Feigenbaum originally designed SMB at IBM in early 1983 with the aim of turning DOS INT 21h local file access into a networked file system. Microsoft has made considerable modifications to the most commonly used version. Microsoft merged the SMB protocol with th… - SMB 2.0
Microsoft introduced a new version of the protocol with Windows Vista in 2006. Although the protocol is proprietary, its specification has been published to allow other systems to interoperate with Microsoft operating systems that use the new protocol. SMB2 reduces the 'chattines...
- Server Message Block provides file sharing, network browsing, printing services, and interprocess communication over a network. The SMB protocol relies on lower-level protocols for transport. The Microsoft SMB protocol was often used with NetBIOS over TCP/IP over UDP, using port numbers 137 and 138, and TCP port numbers 137 and 139. NBT for use by NetBIOS is supporte…
- Although its main purpose is file sharing, additional SMB Protocol provides other functionality such as: 1. Network browsing 2. Printing over a networkSMB Protocol is most often used as an Application layer or a Presentation layer protocol, and it relies on lower-level protocols for transport. 1. The transport layer protocol that Microsoft SMB Protocol was often used with was …
- The specifications for the SMB are proprietary and were originally closed, thereby forcing other vendors and projects to reverse-engineer the protocol in order to interoperate with it. The SMB 1.0 protocol was eventually published some time after it was reverse engineered, whereas the SMB 2.0 protocol was made available from Microsoft's MSDN Open Specifications Developer Center f…
- SMB works through a client-server approach, where a client makes specific requests and the server responds accordingly. One section of the SMB protocol specifically deals with access to filesystems, such that clients may make requests to a file server; but some other sections of the SMB protocol specialize in inter-process communication. The Inter-Process Communication sha…
- In the SMB protocol, opportunistic locking is a mechanism designed to improve performance by controlling caching of network files by the client. Unlike traditional locks, OpLocks are not strictly file locking or used to provide mutual exclusion. There are four types of opportunistic locks: 1. Batch Locks Batch OpLocks were created originally to support a particular behavior of DOS batc…
- CIFS/SMB initially tended to focus on shared file and print services and applications used in small LANs. Microsoft did not add support for transparent reconnects until later, with the third version of the SMB protocol.
- With the respective evolution of the protocols, NFSv4 and SMB3 have become more similar in functionality than they have ever been. But with NFS vs. CIFS, NFS will likely continue to be used primarily in Linux environments, while SMB will remain the dominant choice for Windows.

Server Message Block (SMB) is a communication protocol originally developed in 1983 by Barry A. Feigenbaum at IBM and intended to provide shared access to files and printers across nodes on a network of systems running IBM's OS/2.
