CIFS Protocol Features

CIFS protocol has been widely updated by Microsoft after it acquired it, there are lots of features that were made available for CIFS by them.

  • Supported Transportation Types – Although CISF was mainly created for Connection-oriented The Protocols like TCP, it can also work on the top of a connectionless environment.
  • Connectivity – The CIFS Protocol is extremely flexible in terms of connectivity, there are no limitations to how many servers a single client can connect with. A single client can connect with as many servers as needed at the same time as per the requirement.
  • Access to the Resources – The CIFS client can access multiple files simultaneously and work with them too. Also, there is no File Locking Mechanism available, which means that the same file can be used by multiple clients at the same time.
  • Supports External Protocols – CIFS can also use some external Protocols if needed, which helps in increasing the functionality.
  • Named Pipe Interprocess Communication – CIFS uses Convention the named pipes for the Interprocess Communication between the Client and Server.
  • Supports Batched Commands – CIFS allows the grouping of messages to processed them in sequence.
  • Supports DFS – CIFS also supports the Distributed File System which creates a Global Namespace which includes resources on multiple servers.
  • RPC Support – CIFS Protocol supports the RPC protocols such as MS-RPCE and MS-RAP. As it was acquired by Microsoft it supports most RPC protocols that are developed by Microsoft.
  • Multiple Filesets Naming Convention support – CIFS protocol supports to the UNICODE and ASCII character set.

What is CIFS (Common Internet File System)?

The Common Internet File System (CIFS), additionally called Server Message Block (SMB), is a community file-sharing protocol used for gaining access to documents, printers, and different assets on a community. Initially advanced using IBM in the Eighties and later refined by way of Microsoft, CIFS/SMB has become the de facto popular for sharing files and sources in heterogeneous network environments, inclusive of Windows, Unix, Linux, and macOS systems.

What is CIFS?

CIFS or Common Internet File System is a file-sharing protocol that works in the Application and Presentation Layer. It is mainly used to provide shared access to all the local systems to the remote files or other services like printing remotely, it also provides access to the interprocess communication services, without being available in the same network....

Primary Terminologies Related to CIFS

CIFS (Common Internet File System) – CIFS is a file-sharing protocol across different networks that is primarily used in Windows-based devices, as it is owned and modified by Microsoft. SMB (Server Message Block) – SMB is an underlying protocol that works on the concept of CIFS, CIFS is another dialect or version of the SMB. It starts the communication between the Client and the Server. File Sharing – It is the primary function of the CIFS protocol, It grants access to the files and directories of one device to the other devices present in the network Access Control – Access Control means setting proper permissions to the files and directories in that network, it controls who can access or manipulate the files and directories, and what actions they can perform out of read, write, execute. present in that network. Authentication – Authentication means verifying the identity of the users who will access and manipulate the files and the directories. CIFS Client – A CIFS client is a device that accesses the shared resources hosted in the CIFS servers. It takes the advantage of CIFS protocol to manipulate the shared files or request any access. CIFS Server – A CIFS Server is a device that hosts shared resources and makes them accessible to the CIFS clients, the server responds to the CIFS client’s requests and answers to its File queries....

Working of CIFS

Generally, a Common Internet File System client initiates an application-level communication connection with a CIFS server. For instance, a user can use Windows File Explorer to visit a shared folder. Using a full duplex TCP session over port 139, the client establishes a NetBIOS session with the server, enabling it to access shared resources....

Functionality of CISF

Transport independence: The transport protocol that sends messages between the client and server is not required by CIFS. The protocol can function through connectionless protocols as well as connection-oriented protocols, which are typically used for transport. Flexible connectivity: One person can connect to many servers at once. Feature negotiation: For each connection, a different set of supported features and the CIFS dialect are negotiated. Resource access: On the target server, shared resources including files, named pipes, and print cues are accessible to multiple CIFS clients concurrently. Contexts for security: Clients can establish multiple security contexts over a connection if needed. File access: Multiple clients may view the same file simultaneously since the server controls file sharing. Extended subprotocols: A collection of protocols that allow for more advanced server capability can be utilised in conjunction with CIFS. File and record locking, as well as secure caching: Opportunistic locking allows clients to cache data, improving network performance. File and record locking is also supported by the protocol. File, directory, and volume properties can be viewed and changed by clients thanks to the CIFS specification. Access Control Lists (ACLs) are also compatible with CIFS. Notification of file and directory changes: Clients have the option to be notified via email whenever changes are made to files in a server directory or directory tree....

Difference Between CIFS and NFS

CIFS NFS The Common Internet File System is shortened to CIFS. Network File System is shortened to NFS. Windows operating systems share files using this protocol. Linux and Unix operating systems share files via this protocol. The scalability is poor It has a lot of scalability. The communication pace is mediocre Communication happens quickly. The sessions are provided by this protocol The session is not provided by this protocol. The CIFS protocol is dependable. The NFS protocol is unreliable. Compared to the Network File System, the Common Internet File System is more secure. The protocol used by the network file system is not secure. Its application is complex It is simple to set up and execute this protocol....
