具体方法可以参考:网络安全管理-检查和关闭勒索病毒传播的通讯协议 Disable SMBv1 according to the vendor instructions in Microsoft KB2696547. Additionally, block SMB directly by blocking TCP port 445 on all network boundary devices. For SMB over the NetBIOS API, block TCP ports 137 / 139 and UDP ...
1. Negotiate Protocol Request: 在在用户输入“\服务器名\”之后,首先要做的就是把服务器名解析为IP,可以通过DNS还是NetBIOS解析。得到IP地址后,客户端就向服务器发送第一个SMB请求:“Negotiate Protocol Request”。这个请求包含了客户端所支持的各种 SMB Dialect。 2. Negotiate Protocol Response: 服务器收到该...

SMB is a network file sharing protocol that requires an open port on a computer or server to communicate with other systems. SMB ports are generally port numbers 139 and 445. Port 139 is used by SMB dialects that communicate over NetBIOS. It operates as an application layer network protocol...
The Server Message Block protocol can run on top of the Session (and lower) network layers in several ways: directly over TCP, port 445;[4] via the NetBIOS API, which in turn can run on several transports...
首先是一些基础知识: 1.IP地址和Port(端口号)本机的IP地址:172.0.0.1端口号的范围为0~65535之间(2个字节),0~1023是用于知名网络服务和应用,所以最好不要用0~1023这些端口号2.TCP和UDPTCP:传输控制协议(Transmission Control Protocol)面向连接的通信协议UDP:用户数据报协议(User Datagram ...
on the server. The TCP source port used by the SMB client can be of any TCP port value. The SMB server SHOULD listen for connections on port 445. This port number has been registered with the Internet Assigned Numbers Authority (IANA) and has been officially assigned for Microsoft-DS.<3...
SMB over QUIC offers an "SMB VPN" for telecommuters, mobile device users, and high security organizations. The server certificate creates a TLS 1.3-encrypted tunnel over the internet-friendly UDP port 443 instead of the legacy TCP port 445. All SMB traffic, including authentication and ...
RPC over SMB MUST use aprotocol identifierof 0x0F instead of 0x10, as specified in[C706]Appendix I.<4> The tower encoding for RPC over SMB MUST be the same as what is specified in [C706] Appendix L, for ncacn_ip_tcp. The port address MUST be the endpoint encoded into a NULL-te...
SMB Ports are typically used for file sharing. The SMB protocol allows programs and services on networked computers to communicate with each other.
