Detailed Explanation

SMB - "Server Message Block" - is a file sharing protocol that was invented by IBM and has been around since the mid-eighties. SMB is a protocol meaning an agreed upon way of communicating between systems over a local area network (LAN).[1] Most modern storage systems no longer use CIFS, they use SMB 2 or SMB 3 and NFS “Network File System” CIFS - “Common Internet File System.”- is a particular implementation of the Server Message Block protocol by Microsoft. someone said CIFS is a dialect of SMB. cause SMB version 1 is often associated with CIFS. This is because CIFS is a popular 1996 Microsoft SMB dialect that implemented SMB on many networks. Because CIFS is a form of SMB, a client speaking CIFS can talk to a server speaking SMB and vice versa. While they are the same top level protocol, there are still differences in implementation and performance tuning SMB works at Layer 7 and the packets are in three types session control packets, file access packets and general message packets. The application layer, and uses TCP/IP on port 445 (note: prior to Windows 2000 the SMB port number was 139).

Version Description Limitation
SMB1 SMBv1 is the original implementation of SMB. It was created at IBM in the 1980s.
  • SMB1 used 16-bit packet and small. by today’s standards data buffers is limited in performance.
  • SMBv1 does not have any encryption, which makes it so unsecured. Therefore it shouldn’t be used today.
  • The protocol is highly susceptible to MITM (man-in-the-middle) attacks
  • SMBv1 is the protocol exploited by ransomware like WannaCry and NotPetya.
  • SMB1 is inefficient and creates a lot of network “chatter” when compared to newer SMB versions


Best Practices

  • 최신 버전 사용 권장
  • 공식 문서 참고
  • 테스트 환경에서 먼저 검증
