Introduction A new version of Windows CE triggers changes in CE projects’ design necessary to fit new system requirements. In opposite to previous versions of Windows CE adjustments are significant as a result of changes in kernel architecture. 1.1. Purpose The purpose of the paper is to present differences between Windows Embedded CE 6.0 and previous version of the Windows CE OS. It also includes information about all potential parts of project/code that should be modified

  • 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.

  • 4070 a Remote File and Print Sharing Solution Through Dial-A-LAN Server Stanley Wang Hewlett Packard 19420 Homestead Road, MS 44L4 (408)447-4138
    4070 A Remote File and Print Sharing Solution Through Dial-A-LAN Server Stanley Wang Hewlett Packard 19420 Homestead Road, MS 44L4 (408)447-4138 Advanced Server for HP-UX(AS/9000) supports file and print sharing functionalities, and Microsoft domain services. With AS/9000 implemented on HP-UX, Windows NT and HP-UX work seamlessly in a heterogeneous environment. The ability to access corporation information remotely becomes a critical solution for most corporates. Today, Microsoft has a solution for mobile computing; a new built-in RAS services and point-to-point Tunneling Protocol (PPTP) are available on Windows NT 4.0. Since one of the business charters for our team is integrating PC client on HP-UX, a similar solution on AS/9000 is expected. The HP’s Dial-A-LAN RAS solution seems to be the best candidate at this point. The purpose of this report is to experiment features provided by Dial-A-LAN, and provide a proof-of-concept experience. HP Dial-A-LAN Remote Access Server The HP AdvanceStack Dial-A-LAN is a multi-port, multi-protocol remote access server for networks built with HP AdvanceStack Hubs. There are two models of Dial-A-LANs. They are: J2623A, a two-port internal V.34 28.8Kbps modem port card J2624A, a four-port RS232/V.24 card built for external modem capability A two-port internal modem port card (J2623A) has been added into a HP AdvanceStack Hub for this exercise. Dial-A-LAN provides PC users with the following capabilities: Dial-in capability that allows users to access their network from remote sites Dial-out capability
