NQE™ Network File Sharing NQE™ Network File Sharing Brings File Sharing to the Embedded System What is File Sharing? You are probably using it every day. • Windows Network→Host→Shared Folder→File “File Sharing”: • Expose your own files • View other’s files Either manually or by program. 2 Confidential What is CIFS/SMB? CIFS/SMB is a File Sharing protocol which realizes File Sharing functionality. CIFS（Common Internet File System） SMB（Server Message Block） “File Sharing protocol” includes: CIFS/SMB protocol itself A series of SMB services which runs over the protocols such as: RAP(Remote Administration Protocol) RPC(Remote Procedure Call Services) etc… 3 Confidential Outline of CIFS/SMB history SMB-1982 Designed by IBM (Barry Feigenbaum) PC-DOS – 1984 LAN Manager – 1988 Unix and other operating systems (part of the OS or as a suite like Samba) CIFS- Adopted by Microsoft as of Win95 Common Internet File System Strictly speaking, Windows NT 4.0 – 1996 “CIFS” has started IETF draft – Common Internet File System – 1997 its history from this SNIA Technical Specification – 1999 year. SMB (returned to the original name) - 2000 Windows 2000 Extensions – 2000 So, let’s call the Extensions for other implementations of SMB oldest SMB as SMB1! SMB 2.0 (or SMB2) – 2008 Windows Vista SMB 2.1 (or SMB2.1) – 2010 Windows 7 SMB 3.x (or SMB3) – 2012 Windows 8 4 Confidential SMB2.x and SMB3.0 Re-designed major SMB versions by Microsoft. Performance improvements Much smaller command set ( 75 → 19 ) Improved request compounding (reduced round trips) Asynchronous operations (Multiple packets sent concurrently) Larger reads/writes (more data in each packet) Security improvements SMB Durability provide limited network fault tolerance Signing – Uses HMAC SHA-256 instead of old MD5 SMB Encryption Now that IBM cannot interfere Increased file sharing scalability any more. 5 Confidential SMB versions – Who speaks what? Windows 8 Windows 7 Windows Vista Previous versions Client / Server OS Windows Server Windows Server Windows Server of Windows 2012 2008 R2 2008 Windows 8 Windows Server SMB 3.0 SMB 2.1 SMB 2.0 SMB 1.0 2012 Windows 7 Windows Server SMB 2.1 SMB 2.1 SMB 2.0 SMB 1.0 2008 R2 Windows Vista Windows Server SMB 2.0 SMB 2.0 SMB 2.0 SMB 1.0 2008 Previous versions SMB 1.0 SMB 1.0 SMB 1.0 SMB 1.0 of Windows 6 Confidential SMB – The future of SMB1.0 • Prior to Windows 8.1 SMB1 was an integral part of the OS. • Starting from 8.1 SMB1 is an optional component that may be disabled. It’s still enabled by default. • In the next Windows release We will make SMB1 disabled by default, So that a user will need to turn it on. Not each user knows how to do that. • Later on We are planning to remove SMB1. • We consider the 8.1 case as a "yellow warning" for those that still count on SMB1. Announced at SDC in Sep 18, 2013 By - Jose Barreto Principal Program Manager Windows 8 Windows 8.1 File Server Team, Microsoft Jose Barreto’s Blog ( http://smb3.info ) 7 Confidential SMB vs. others TFTP, FTP, HTTP Advantage : The most standard protocol supported by a variety of applications. Disadvantage : - Pre-installation is required for both of client and server. (and for both of Windows and UNIX) - Configuration is complicated. - File transfer is the main job so downloading/uploading is required for file operations. NFS Advantage : Seamless linkage with OS. (Depending on each distribution) Disadvantage : - Not supported by Windows machines ( besides Windows server ) - Configuration is complicated. SMB Advantage : Windows standard protocol - Seamless authentication mechanism with OS. - Can be used even in UNIX machines by using SMB. - Easy Configuration. - Direct “open” and “modification” is allowed because of its nature of “File Sharing protocol”. - Temporary area is not needed. Disadvantage : Installation of Samba is required for UNIX machines. 8 Confidential NQE – What’s NQE The leading (and the only viable) Commercial SMB In the Market today.

  • IT Security Principles: Windows Exploitation
    IT Security Principles: Windows Exploitation IT 444 – Network Security Understanding LLMNR and NBNS • Windows systems go through several different steps to resolve a hostname to an IP address for us. • Windows will search the hosts or LMHosts file on the system to see if there’s an entry in that file. • If there isn’t, then the next step is to query DNS. Windows will send a DNS query to the default nameserver to see if it can find an entry. • In most cases, this will return an answer, and we’ll see the web page or target host we’re trying to connect to. • In situations where DNS fails, modern Windows systems use two protocols to try to resolve. LLMNR and NetBios Understanding LLMNR and NBNS o LLMNR: this protocol uses multicast in order to try to find the host on the network. Other Windows systems will subscribe to this multicast address, and when a request is sent out by a host, if anyone listening owns that name and can turn it into an IP address, a response is generated. Once the response is received, the system will take us to the host o If the host can’t be found using LLMNR, Windows use the NetBIOS protocol to try to discover the IP. It does this by sending out a broadcast request for the host to the local subnet, and then it waits for someone to respond to that request. If a host exists with that name, it can respond directly, and then our system knows that to get to that resource, it needs to go to that location Understanding LLMNR and NBNS o Both LLMNR and NBNS rely on trust o As a malicious actor, though, we can respond to any request sent out to LLMNR or NBNS and say that the host being searched for is owned by us.

  • Information Protection Personal Computers Local Area Networks
    A Short Course on Information Protection in Personal Computers and Local Area Networks by Dr. Frederick B. Cohen ASP Press FAX:412-422-4135 PO Box 81270 TEL:412-422-4134 Pittsburgh, PA 15217 USA ISBN#1-878109-14-6 Copyright c 1991, ASP ALL RIGHTS RESERVED Made in the USA by ASP Contents i 1 Introduction The proliferation of Personal Computers (PCs) and Local Area Networks (LANs) has brought about a resurgence in computer security problems that were largely solved for main- frames, and a wide variety of new problems that are specific to PC and LAN technologies. In most PCs, there are no access controls, backups are poorly managed if they are kept at all, the operating system can be accidentally corrupted, and denial of service is commonplace. In most LANs, the access controls in place can be easily violated, there is no protection against any user examining or modifying most of the network traffic, and existing controls are not adequately used. Subtle interactions between different machines on LANs can extend security problems, sometimes making even seemingly secure environments open to simplistic attacks. The purpose of this book is to explain the nature and scope of PC and LAN protection problems, describe the defenses available today and the tradeoffs in their use, and to discuss available tools for understanding the technology. 1 About the author: Dr. Cohen is widely known in computer security circles, where he has developed basic the- ory, performed ground-breaking experiments, prototyped practical solutions in widespread use, developed commercial security products for over 15 years, and provided security prod- ucts and services to organizations worldwide.
