Which is more secure CIFS or NFS?

The main difference between these two types of communication systems are CIFS can used only in Windows operating system, whereas NFS can be used in UNIX and LINUX based systems. In terms of security, CIFS provides better network security than NFS. On the other hand, NFS offers higher scalability features than CIFS.

Is CIFS a secure protocol?

Is CIFS Secure? CIFS is an unsecure implementation of SMB – its lack of encryption has seen it exploited through malware like NotPetya and the WannaCry ransomware attack, which occurred through a zero-day exploit called EternalBlue.

What’s the difference between CIFS and NFS?

NFS is a transport-dependent protocol and offers a high rate of communication speed. CIFS is generally used for direct hosting and NetBIOS-dependent transport over IP and TCP protocols.

Which Is More Secure NFS or SMB?

In random read, NFS and SMB fare equally with plain text. However, NFS is better with encryption. In the case of random writing, NFS is better than SMB in both plain text and encryption. If you use rsync for file transfer, NFS is a better choice in plain text and encryption.

Does Windows use CIFS or NFS?


CIFS stands for Common Internet File System. NFS stands for Network file system.
CIFS is developed as a common internet file system used to create limited access in windows operating systems. The network file system is compressed as NFS and mainly used on UNIX or LINUX operating systems.

Does CIFS use encryption?

CIFS/SMB doesn’t have any protocol-level encryption options as of SMBv2, so you’re stuck encapsulating the traffic in an encrypted envelope. Which in all practicality means a VPN of some kind. Be it IPSEC, SSL, PPTP.

Is CIFS obsolete?

CIFS is now considered obsolete, because most modern data storage systems use the more robust Server Message Block (SMB) 2.0 and 3.0 file-sharing protocols, which were major upgrades to CIFS. CIFS/SMB and the Network File System (NFS) are the two major protocols used in network-attached storage (NAS) systems.

Are CIFS and SMB the same?

CIFS (Common Internet File System) and SMB (Server Message Block) are both Windows file-sharing protocols used in storage systems, such as network-attached systems (NAS). The key difference between CIFS and SMB is that CIFS is a dialect of SMB – a particular implementation of the SMB protocol.

Is NFS same as NTFS?

NTFS is the filesystem. NFS is a network protocol. iSCSI is SAN (block storage.)

Is NFS faster than SSH?

For access of large files over the network, NFS is of course much faster than anything with an SSH transport.

Is Linux NFS secure?

NFS is well suited for sharing entire file systems with a large number of known hosts in a transparent manner. However, with ease of use comes a variety of potential security problems. The following points should be considered when exporting NFS file systems on a server or mounting them on a client.

Can SMB be encrypted?

SMB Encryption can be configured on a per share basis or for the entire file server, and it can be enabled for a variety of scenarios where data traverses untrusted networks. SMB Encryption does not cover security at rest, which is typically handled by BitLocker Drive Encryption.

Is SMB port 445 secure?

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

What is the difference between CIFS and SMB and NFS?

NFS (Network File System) and CIFS (Common Internet File System) are protocols designed to allow a client system to view and access files stored on a remote computing device, such as a server or a PC. CIFS is a dialect of the Server Message Block (SMB) protocol that is used by most current storage systems.

Does Linux support CIFS?

CIFS is a network-based file-sharing protocol which is used to share file, folders, and data over the network. The Windows, Linux, MacOSX, and other operating systems support the CIFS which makes it very useful to share files and folders over different operating systems.

Is Samba still used?

Samba is a software package that gives network administrators flexibility and freedom in terms of setup, configuration, and choice of systems and equipment. Because of all that it offers, Samba has grown in popularity, and continues to do so, every year since its release in 1992.

What protocol does NFS use?

All versions of NFS can use Transmission Control Protocol (TCP) running over an IP network, with NFSv4 requiring it. NFSv2 and NFSv3 can use the User Datagram Protocol (UDP) running over an IP network to provide a stateless network connection between the client and server.

Can I mount NFS on Windows?

Mounting the NFS Share

Open a Powershell command prompt. Run the appropriate command for your situation: Server OS: Install-WindowsFeature NFS-Client. Desktop OS: Enable-WindowsOptionalFeature -FeatureName ServicesForNFS-ClientOnly, ClientForNFS-Infrastructure -Online -NoRestart.

How can I improve my NFS performance?

Follow these steps in sequence to improve the performance of your NFS server.

  1. Measure the current level of performance for the network, server, and each client.
  2. Analyze the gathered data by graphing it.
  3. Tune the server.
  4. Repeat Steps 1 through 3 until you achieve the desired performance.

What are the components of NFS?

NFS device (server) – a storage device or a server that uses the NFS protocol to make files available over the network. NFS datastore – a shared folder on the NFS server that can be used to hold virtual machine files. NFS client – ESXi includes a built-in NFS client used to access an NFS device.

Which is better iSCSI or NFS?

In a software iSCSI implementation, performance is slightly higher, but the CPU load on the client host is also higher. iSCSI also puts a higher load on the network. iSCSI generates more network traffic and network load, while using NFS is smoother and more predictable.

Is SCP faster than NFS?

cp and scp are faster than their respective rsync -av equivalents. Writing directly to exported NFS share is significantly slower (at least 2 times) than writing to the same directory over SSH, regardless of the method used. Differences between cp and rsync are not relevant in this case.

Does NFS use SSL?

If you need access to NFS across the internet, use a VPN (IPSEC, SSL tunnel, SSH tunnel, even pptp) and BLOCK all direct internet access (other than the secure connection) on the server.

Does NFS have authentication?

NFS V4 normally authenticates clients at the user level rather than at the host level. The two user authentication methods are auth_sys (UNIX authentication) and RPCSEC_GSS (Kerberos). Under the auth_sys security method, the user is authenticated at the client, usually through a logon name and password.

What port does NFS use?

NFS uses port 2049. NFSv3 and NFSv2 use the portmapper service on TCP or UDP port 111.

Why is port 445 blocked?

Port 445 is associated with SMB (Service Message Block), an application layer network protocol that is mostly used for file sharing, printer sharing, and serial port sharing. Port 445 is vulnerable to security assaults, according to security researchers, and should be deactivated.

Is NFS v4 secure?

If you use NFSv4 with sec=krb5p , then it is secure. (That means use Kerberos 5 for authentication, and encrypt the connection for privacy.) But if you use NFS v3 or NFS v4 with sys=system , then no, it’s not secure at all.

How do you protect data in transit?

Data at Rest and Data in Transit Encryption

Encryption can protect both data in transit and data at rest. One of the most effective ways to protect data is by using encryption. That way, even if there are any security breaches or attacks on your company’s system, all of the information will be protected.

Is SMB 1.0 CIFS file sharing support safe?

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 encrypted by default?

SMB Encryption is disabled by default and can be enabled on the file server for all shares or for each individual share. server.

What is port 445 commonly used for?

Port 445 is a traditional Microsoft networking port with tie-ins to the original NetBIOS service found in earlier versions of Windows OSes. Today, port 445 is used by Microsoft Directory Services for Active Directory (AD) and for the Server Message Block (SMB) protocol over TCP/IP.


SMB relies on the TCP and IP protocols for transport. This combination potentially allows file sharing over complex, interconnected networks, including the public Internet. The SMB server component uses TCP port 445.

How do you unmount CIFS?

To force unmount a CIFS share in Linux, do the following.

  1. Open your favorite terminal app.
  2. Type the following command: sudo umount -a -t cifs -l , then supply your password.
  3. If the sudo command is not available in your environment, switch to root with the su command, and then issue the command umount -a -t cifs -l.

How do I create a CIFS share?


  1. From the home page, double-click the appropriate storage system.
  2. In the navigation pane, click Storage > Shares.
  3. Click Create.
  4. Click Browse and select the folder, qtree, or volume that should be shared.
  5. Specify a name for the new CIFS share.
  6. Provide a description for the share and click Create.

What is CIFS used for?

Common Internet File System (CIFS) is a network filesystem protocol used for providing shared access to files and printers between machines on the network. A CIFS client application can read, write, edit and even remove files on the remote server.

What is the latest NFS version?

NFSv4, the current version of NFS, and other versions subsequent to NFS version 2 (NFSv2) are usually compatible after client and server machines negotiate a connection.

How do I know if NFS is working?

To verify that NFS is running on each computer:

  1. AIX® operating systems: Type the following command on each computer: lssrc -g nfs The Status field for NFS processes should indicate active .
  2. Linux® operating systems: Type the following command on each computer: showmount -e hostname.

Where are NFS files stored?

On our machines all NFS file systems are mounted under /home/ machine-name / file-system , so in the previous example, machine_name was rigel , and file_system was bacon . NFS provides a means of allowing file systems form one system to appear on another. Again, this should appear transparent to the user.

Who fills NFS request?

After the client has determined that a service is running on that port number, the client then makes a mount request. When the server responds to this request, it includes the file handle for the file system (9000) that is being mounted. The client then sends a request for the NFS port number.

How do I find my NFS server IP?

Steps. Next, run ‘netstat -an | grep 2049’ to display a list of NFS connections. Look for the connection that matches one of the NFS server IP from nfslookup. This is the NFS server IP that the client is using and will be the IP you need to use for tracing if necessary.
