Is NFS safer than SMB?

However, with encryption, NFS is slightly better than SMB. In the case of a random read, the performance of NFS and SMB are almost the same when using plain text. However, with encryption, NFS is better than SMB. And for random write, NFS is slightly better than SMB when using plain text and encryption.

Should I use NFS or SMB?

As you can see NFS offers a better performance and is unbeatable if the files are medium sized or small. If the files are large enough the timings of both methods get closer to each other. Linux and Mac OS owners should use NFS instead of SMB. Sadly most Windows users are forced to use SMB.

Is NFS secure?

NFS itself is not generally considered secure – using the kerberos option as @matt suggests is one option, but your best bet if you have to use NFS is to use a secure VPN and run NFS over that – this way you at least protect the insecure filesystem from the Internet – ofcourse if someone breaches your VPN you’re …

Is SMB secure?

1.1), many network administrators and security professionals wonder if it should be deployed on networks or not. Generally speaking, the latest and patched version of SMB is considered as a secure protocol.

Should I use NFS?

5 Answers. In a closed network (where you know every device), NFS is a fine choice. With a good network, throughput it disgustingly fast and at the same time less CPU intensive on the server. It’s very simple to set up and you can toggle readonly on shares you don’t need to be writeable.

Is NFS faster than Sshfs?

NFS still the fastest in plaintext, but has a problem again when combining writes with encryption. SSHFS is getting more competitive, even the fastest from the encrypted options, overall in the mid. The latency mostly resembles the inverse IOPS/bandwith.

How do I protect NFS share?

General guidelines for securing Network File System

  1. Configure the NFS server to export file systems with the least amount of privileges necessary. …
  2. Configure the NFS server to export file systems explicitly for the users who should have access to it. …
  3. Exported file systems should be in their own partitions.

How does NFS security work?

An NFS uses a basic system where a “mount” command will prompt the server to link with many clients. The clients will get access to the same files on the server through the proper platform. The design can use security protocols to dictate who will access certain files, producing a simplified and safe approach to work.

Why NFS is used?

NFS is an Internet Standard, client/server protocol developed in 1984 by Sun Microsystems to support shared, originally stateless, (file) data access to LAN-attached network storage. As such, NFS enables a client to view, store, and update files on a remote computer as if they were locally stored.

Which SMB version is secure?

Of the 3 major SMB versions, SMB3 — particularly SMB 3.1. 1 — offers the most security. For example, SMB3’s secure dialect negotiation limits susceptibility to man-in-the-middle (MITM) attacks and SMB 3.1. 1 uses secure and performant encryption algorithms like AES-128-GCM.

Is SMB 2.0 secure?

The SMB 2.0. 2 and SMB 2.1 dialects do not support encryption. … For data that requires stricter security, encryption by the SMB protocol version 3 is preferred. Alternatively, encryption of the data by the underlying transport is provided.

Is port 445 a security risk?

‍Ports 135-139 and 445 are not safe to publicly expose and have not been for a decade.


3 Answers. NFS is, or can be, a SAN – so you have an issue with definitions. Certainly a 1Gbps NFS storage solution used over a network shared with other traffic is likely to be slower than a dedicated 10/40/100Gbps FCoE network, but then again you can run NFS at those speeds and over a dedicated network.

Is SMB Version 3 Secure?

SMB 3.0 enables file servers to provide continuously available storage for server applications, such as SQL Server or Hyper-V. Enabling SMB Encryption provides an opportunity to protect that information from snooping attacks.

Can Windows read NFS?

The NFS client must be enabled on the client Windows system. The Windows 7 operating system can provide an NFS client, but the NFS client service is disabled by default, and must be enabled for access to NFS exports from the Storwize V7000 Unified system.
