What can be used instead of SMB?

Re: Alternatives to Microsoft Shares/SMB? FTP or SFTP would definitely accomplish what you want. Filezilla and WinSCP are both nice clients. In the Linux world there is NFS, but I don’t about clients/solutions for interacting with NFS shares in Windows.

Why do I need SMB?

The SMB protocol enables applications and their users to access files on remote servers, as well as connect to other resources, including printers, mailslots and named pipes. SMB provides client applications with a secure and controlled method for opening, reading, moving, creating and updating files on remote servers.

How insecure is SMB1?

SMBv1 vulnerability is dangerous for larger networks. A modest home LAN should avoid SMBv1, but an old device disconnected from the internet cannot be used as an entry-point by an attacker. For more information, see : Microsoft’s advisory Stop using SMB1.

Is SMB still used?

SMB2 has now become SMB3. This is more of a marketing move since SMB3 still uses the MS-SMB2 protocol spec. There were just enough changes between SMB 2.1 and SMB 3.0 to justify a new major version. On an interesting historical note, SMB3 was originally SMB 2.2 until the marketing team got involved.

Is SMB signing necessary?

It is pointless unless you are using SMB1. SMB2 signing is controlled solely by being required or not, and if either the server or client require it, you will sign. Only if they both have signing set to 0 will signing not occur. Again, SMB signing is always enabled in SMB2+.

What happens if SMB is disabled?

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).

Should I disable SMB?

It is recommended to disable SMB version 1 since it is outdated and uses technology that is almost 30 years old. Says Microsoft, when you use SMB1, you lose key protections offered by later SMB protocol versions like: Pre-authentication Integrity (SMB 3.1. 1+) – Protects against security downgrade attacks.

What is the best alternative to SMB?

You will have to use SMB or CIFS if you want network-based storage. This done on purpose by Microsoft. The only really useful alternative is Webdav. If you setup a apache server you can use secure HTTPS and whatever authentication method you like to serve files.

Is SMB safe to use?

It depends on which version of SMB you need. There are many versions. NFSv3 is worst out there, by far. SMB can use decently strong auth and encryption if you set it up that way. NFSv3 cannot. But it’s all mute anyways because he requested Windows support and NFS is just misery on that platform.

What is SMB1 protocol?

SMB1 SMB1 is very similar to the CIFS protocol that shares the files over a network to access them among the clients in an effective way. SMB was initially introduced to run on top of NetBIOS and TCP/IP interface. SMB Version 1 Protocol was giving performance issues as it was using an ineffective way of networking resources.

Is samba V2 vulnerable to WannaCry?

SMBv2 and SMBv3 were designed to replace the original SMB protocol and the CIFS protocol. Samba is one software program that implements the SMB, CIFS, SMBv2, and SMBv3 protocols. It is designed to run on POSIX operating systems, including Linux. Samba is not vulnerable to WannaCry.
