Use Server Message Block SigningThe server message block (SMB) protocol is used for communications between Windows computers. SMB signing is a process that ensures that the communication received by a computer was actually sent by the computer referenced as the source. This is an important security setting because even if authentication is established between domain member computers, after the session start, communications may be vulnerable to man-in-the-middle attacks. When SMB signing is required, the Windows computer signs each message it sends. The Windows computer that receives the message can and does check to ensure that the source of the communication is valid. SMB signing is enabled by default on Windows Server 2003. SMB signing is very resource-intensive and can significantly impact performance by up to 30 percent.TIP: Legacy Systems Can Be Configured to Do SMB SigningWindows 2000, Windows Server 2003, and Windows XP Professional can be easily configured to do SMB signing using Group Policy. Knowledge Base article 555038 explains how Windows NT 4.0 and Windows 98 can be configured to do SMB signing (http://support.microsoft.com/default.aspx?scid=kb;en-us;555038).Four Security Options are used to configure SMB signing in Windows Server 2003, two for the client and two for the server. The Security Options are as follows:Microsoft Network client: Digitally sign communications (always)Microsoft Network client: Digitally sign communications (if server agrees)Microsoft Network server: Digitally sign communications (always)Microsoft Network server: Digitally sign communications (if client agrees) Message signing is negotiated during the connection request. If the server or client must (always) do message signing, and its counterpart cannot, communications will not be permitted. Because this setting is enabled by default on Windows Server 2003, Windows 2000 and legacy clients will not be able communicate with Windows Server 2003 computers. If you must provide these systems with access to Windows Server 2003, you will have to configure them to use SMB signing or disable the Security Option in Windows Server 2003. If at all possible, retain the default settings. |
