A Live Digital Forensic system for Windows networks

Abstract: This paper presents FOXP (computer FOrensic eXPerience), an open source project to support network Live Digital Forensics (LDF), where the network nodes run a Windows NT family Operating System (OS). In particular, the FOXP architecture is composed of a set of software sensors, once for every network node, that log node activities and then send these logs to a FOXP collector node; this collector node analyzes collected data and manages the sensors activities. Software sensors, implementing the technique called System Call Interposition for Win32, intercepts all the kernel API (native API) invoked by the OS of the node. Thanks to the fine granularity of the logs, FOXP can intercept malicious activities. Centralized logs collected in the collector node, allow to detect coordinated-attacks on network nodes: attacks that would not be detectable with a single node analysis only. Note that the implemented System Call Interposition technique has allowed to intercept and redirect all of the 284 Windows XP system calls. The technique is exposed in detail and could be considered a contribution on its own. Finally, an overview of next steps to complete the FOXP project is provided.

Realization of Files Sharing between Linux and Windows Based on Samba

Abstract: With the development of computer network, there are multiple operation systems in one local area network frequently. Windows and Linux are comparatively popular within these operating systems. It is necessary to realize files sharing between different operating systems in local area network. Samba software package, as the bridge across Windows and Linux, can help us resolve the problem. This paper introduces SMB protocol and configuration of Samba primarily. Afterwards it introduces the method that how to realize reversible files sharing between Linux and Windows based on software package, and illustrates the difference when Windows 98 and Windows NT share files and printers from Linux.

Performance analysis of network operating systems in local area networks

Abstract: In this paper, in a laboratory environment the performance of four different operating systems (Windows NT4, Windows 2000, Windows 2003, and Linux Fedora) are compared. The performance parameters measured are bandwidth and network delay. Linux Fedora provided the highest bandwidth for a file server at 17.1Mbps, Windows 2000 was fastest for a FTP (83.2Mbps), and Windows 2003 and Windows 2000 gave the highest bandwidth for a web server (4.3Mbps and 4.5Mbps respectively).

Implementations of Montgomery Multiplication Algorithms in Machine Languages.

Abstract: Software implementations of public-key algorithms such RSA and Diffie-Hellman are often desired because of their flexibility and cost effectiveness. In order to obtain the required level of performance on a selected platform, developers turn to implement efficient algorithms in machine (assembly) languages for basic (kernel) operations. Among these basic operations, modular multiplication and exponentiation operations play an important role. This study concerns with fast software implementations of the Montgomery multiplication algorithms. Montgomery multiplication algorithms, which are the most popular algorithms used in public-key cryptography, serve as efficient algorithms for modular multiplication and exponentiation operations. In this paper implementations of five well known algorithms of Montgomery multiplication are given. Algorithms are implemented in assembly languages of Intel Pentium family and Sun Sparc family microprocessors. In order to get comprehensive performance results, they run on Windows 95, Windows 98, Windows NT 4.0, and Solaris 2.5.1 operating systems. The performance results are summarized with a comparison of the algorithms based on their software performances. Index Terms — Montgomery Multiplication, RSA and Diffie-Hellman Cryptosystems, Public-key cryptography.

Quick Windows Batches to Control SAS Programs Running Under Windows and UNIX

Abstract: Very often programmers use Windows operating system and UNIX system on a server to submit their programs. For such programmers it is convenient sometimes (for example because of Windows Microsoft Office usage in adhoc reporting departments) to build a Windows batch job and control submitted programs in Windows environment. The paper presents how to build quickly Windows batches to execute programs under Windows and/or UNIX with the focus how to control execution errors in only Windows environment. The SAS/CONNECT  is applied to submit programs running under UNIX. Both an included code technique and an approach with SYSTASK will be presented. The advantage of using SYSTASK against the included code will be discussed. Some interesting facts about SAS  program errors will be presented. Also the differences between calling Windows commands from inside a program and from a batch file will be analyzed. In addition, invoking FTP procedures, email system, zipping software and calling other executables related to SAS programming also will be presented. All solutions will be analyzed by providing ready-to-apply code. Batch examples presented in this paper are related to Windows XP and UNIX 64HP operating systems. All SAS code was executed using the SAS 9.1.3 version.

Communication Processor's Boot Loader and I/O Interface Driver

Abstract: 【】Aiming at the design of the Ethernet/IP communication processor, this paper adopts S3C2410 ARM9 microprocessor and Windows CE.NET operating system to develop the communication processor’s Boot Loader program and I/O interface’s driver. The Boot Loader program, which is highly relevant to the hardware, initializes hardware platform and boots Windows CE.NET OS. While the I/O interface’s driver makes the OS detect peripherals automatically, and provides services for the applications to control the bottom equipments. Experimental results show that the Ethernet/IP communication processor operates steadily and credibly. 【Key words】Boot Loader; Windows CE.NET; driver
