  • dce rpc over smb samba and windows nt domain internals an expert guide on improving and effeciency and security on windows nt
    1999
    Co-Authors: Luke Kenneth Casson Leighton
    Abstract:

    From the Publisher: Designed to provide in-depth technical information for CIFS implementers, network security experts, developers of network traffic analysis tools, developers of Windows NT software, and network administrators. DCE/RPC over SMB: Samba and Windows NT Domain Internals covers such topics as: implementing DCE/RPC over SMB in Samba; developing NT Domain administration functionality; understanding the internetworkings of Windows NT's internal security components; using the NT service control manager over-the-wire; and managing a Windows NT SAM Database. If you deal with Windows NT development, security, or administration, DCE/RPC over SMB: Samba and Windows NT Domain Internals is an essential source of information on: encrypting DCE/RPC using NTLM Secure service Provider; Viewing files, shares, and sessions that are open on a server; and adding, modifying, and deleting keys and values on the NT registry.

  • Windows access control demystified
    Princeton University, 2006
    Co-Authors: Sudhakar Govindavajhala, Aw Appel
    Abstract:

    In the Secure Internet Programming laboratory at Princeton University, we have been investigating network security management by using logic programming. We developed a rule based framework — Multihost, Multistage, Vulnerability Analysis(MulVAL) — to perform end-to-end, automatic analysis of multi-host, multi-stage attacks on a large network where hosts run different operating systems. The tool finds attack paths where the adversary will have to use one or more than one weaknesses (buffer overflows) in multiple software to attack the network. The MulVAL framework has been demonstrated to be modular, flexible, scalable and efficient [20]. We applied these techniques to perform security analysis of a single host with commonly used software. We have constructed a logical model of Windows XP access control, in a declarative but executable (Datalog) format. We have built a scanner that reads access-control configuration information from the Windows registry, file system, and service control manager database, and feeds raw configuration data to the model. Therefore we can reason about such things as the existence of privilege-escalation attacks, and indeed we have found several user-to-administrator vulnerabilities caused by misconfigurations of the access-control lists of commercial software from several major vendors. We propose tools such as ours as a vehicle for software developers and system administrators to model and debug the complex interactions of access control on installations under Windows.

  • HTCondor 8.8.2
    2019
    Co-Authors: Htcondor Team
    Abstract:

    Highlights of this release are: - Fixed problems with condor_ssh_to_job and Singularity jobs - Fixed a problem that could cause condor_annex to crash - Fixed a problem where the job queue would very rarely be corrupted - condor_userprio can report concurrency limits again - Fixed the GPU discovery and monitoring code to map GPUs in the same way - Made the CHIRP_DELAYED_UPDATE_PREFIX configuration knob work again - Fixed restarting HTCondor from the service control manager on Windows - Fixed a problem where local universe jobs could not use condor_submit - Restored a deprecated Python interface that is used to read the event log - Fixed a problem where condor_shadow reuse could confuse DAGMan More details about the fixes can be found in the Version History
