SMB uses either IP port or Leaving network ports open to enable applications to function is a security risk. So how do we manage to keep our networks secure and maintain application functionality and uptime?
Here are some options to secure these two important and well-known ports. In addition to the network specific protections above, you can implement a data centric security plan to protect your most important resource — the data that lives on your SMB file shares.
Understanding who has access to your sensitive data across your SMB shares is a monumental task. Varonis maps your data and access rights and discovers your sensitive data on your SMB shares.
Monitoring your data is essential to detect attacks in progress and protect your data from breaches.
Varonis can show you where data is at-risk on your SMB shares and monitor those shares for abnormal access and potential cyberattacks.

For more information about best practices and scans, see Best Practices Analyzer. SMB functions as a request-response or client-server protocol.
The only time that the protocol does not work in a response-request framework is when a client requests an opportunistic lock oplock and the server has to break an existing oplock because the current mode is incompatible with the existing oplock.
CIFS: The old version of SMB, which was included in Microsoft Windows NT 4. SMB 1. SMB 2. SMB 3. This version supports AES GCM encryption in addition to AES CCM encryption added in SMB3, and implements pre-authentication integrity check using SHA hash.
The SMB protocol supports two levels of security. The first is the share level. The server is protected at this level and each share has a password.
The client computer or user has to enter the password to access data or files saved under the specific share. This is the only security model available in the Core and Core plus SMG protocol definitions.
User level protection was later added to the SMB protocol. It is applied to individual files and each share is based on specific user access rights.
The SMB protocol has supported individual security since LAN Manager 1. To identify the following information of Windows or Samba system, every pentester go for SMB enumeration during network penetration testing.
Here you can observe, we are using nmap the most famous network scanning tool for SMB enumeration.
As a result, we enumerated the following information about the target machine:. During the enumeration phase, generally, we go for banner grabbing to identify a version of running service and the host operating system.
Over the years, there have been many security vulnerabilities in Microsoft's implementation of the protocol or components on which it directly relies.
Real-time attack tracking  shows that SMB is one of the primary attack vectors for intrusion attempts,  for example the Sony Pictures attack ,  and the WannaCry ransomware attack of The specifications for the SMB are proprietary and were originally closed, thereby forcing other vendors and projects to reverse-engineer the protocol in order to interoperate with it.
