Do people still use SMB?

The CIFS implementation of SMB is rarely used these days. Under the covers, most modern storage systems no longer use CIFS, they use SMB 2 or SMB 3. In the Windows world, SMB 2 has been the standard as of Windows Vista (2006) and SMB 3 is part of Windows 8 and Windows Server 2012.

Is SMB obsolete?

Summary. In Windows 10 Fall Creators Update and Windows Server, version 1709 (RS3) and later versions, the Server Message Block version 1 (SMBv1) network protocol is no longer installed by default. It was superseded by SMBv2 and later protocols starting in 2007. Microsoft publicly deprecated the SMBv1 protocol in 2014.

Does Windows 10 use SMB?

Server Message Block (SMB) is a networking file share protocol included in Windows 10 that provides the ability to read and write files and perform other service requests to network devices.

What happens if I turn off SMB?

Disabling SMBv1 without thoroughly testing for SMBv1 traffic in your environment can have unintended consequences, up to and including a complete suspension of all network services, denied access to all resources, and remote authentication failures (like LDAP).

Why is SMB v1 bad?

You can't connect to the file share because it's not secure. This share requires the obsolete SMB1 protocol, which is unsafe and could expose your system to attack.

Is NFS better than SMB?

NFS offers better performance and is unbeatable if the files are medium-sized or small. For larger files, the timings of both methods are almost the same. In the case of sequential read, the performance of NFS and SMB are almost the same when using plain text. However, with encryption, NFS is better than SMB.

Should you disable SMB?

If you're not using any of these applications—and you probably aren't—you should disable SMBv1 on your Windows PC to help protect it from any future attacks on the vulnerable SMBv1 protocol. Even Microsoft recommends disabling this protocol unless you need it.

What SMB version does Windows 10 use?

Currently, Windows 10 supports SMBv1, SMBv2, and SMBv3 as well. Different servers depending upon their configuration require a different version of SMB to get connected to a computer. But in case you are using Windows 8.1 or Windows 7, you can check if you have it enabled too.

Is SMB enabled by default in Windows 10?

SMB 3.1 is supported on Windows clients since Windows 10 and Windows Server 2016, it is by default enabled.

Should I disable SMB?

If you're not using any of these applications—and you probably aren't—you should disable SMBv1 on your Windows PC to help protect it from any future attacks on the vulnerable SMBv1 protocol. Even Microsoft recommends disabling this protocol unless you need it.

How is Microsoft SMB used in the network?

• Determining other Microsoft SMB Protocol servers on the network, or network browsing In the OSI networking model, Microsoft SMB Protocol is most often used as an Application layer or a Presentation layer protocol, and it relies on lower-level protocols for transport.

Is it safe to use the SMB protocol?

• SMB revealed a dangerous vulnerability in a massive cyberattack, that affected hundreds of thousands of people. You may not have heard of the SMB protocol but it's an integral part of how the internet operates. Luckily, there IS a way to use the SMB protocol safely.

How is SMB used in the real world?

• If you are working with your colleagues, then you can use SMB to establish a server as your central repository for sharing files. The entire idea of SMB is to allow remote access, so being present in the office is not a requirement. You could be half-way across the world and still be able to access the server.

Which is version of SMB do I Need?

• It’s important to know which version of the SMB protocol your device uses, especially if you own a business and have a lot of Windows machines connected to each other. It would be hard to find a PC running Windows 95 or XP (and using SMBv1) in a modern-day office, but they might still be running on old servers.
