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). 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 --- References Samba --- Related Pages Linux Server Hardware Network ---
