whitepaper Enforcing Security Enhanced Linux Policies in a Networked Policy Domain2007-02-04 Tresys Technology
  Significant progress toward general acceptance of applying mandatory access control to systems has been made recently. Security Enhanced Linux (SELinux), in particular, has been enabled by default in some Linux distributions for several years. However, current SELinux deployments only effectively control a single system. Inter-system and remote resource access control capabilities are starting to appear in SELinux, but extending policy management capabilities to cover these networked systems remains an open problem. This paper discusses issues that must be addressed to support security policies distributed across a network, including policy development changes needed to be able to express a coherent security policy for a network of systems, managing the distribution of a multi-system policy, and synchronizing policy updates, and compares options to provide this support.

whitepaper Reducing Risk Through Linux2007-02-01 Novell
  Software decisions are risky. They result in major multi-year resource commitments, both financial and human, and can shape the future of the enterprise. This is particularly true regarding foundational Operating System (OS) software for desktops and servers. Even if software were free, CIOs wouldn't be employed for long if the OS software they chose were not reliable, functionally rich, secure and above all else, cost-effective. For CIOs, the decision to commit to open source software isn't about ideology; it is very often about minimizing risk.

whitepaper Real-Time Capabilities for Linux SGI REACT Real-Time for Linux2007-02-01 SGI
  This white paper describes the real-time capabilities provided by SGI REACT Real-Time for Linux software. REACT enables SGI Linux-based system platforms to deliver Hard Real-Time (HRT) capabilities including an interrupt response time of 30us or less. A brief review of current real-time Linux capabilities, a description of typical real-time applications, and a comparison of SGI real-time capabilities for Linux versus IRIX are also included.   
whitepaper Secunia Vulnerability Study: Summary and Analysis2007-01-15 Microsoft
  This paper compares the security of Red Hat Enterprise Linux ES 3, Red Hat Enterprise Linux ES 4, and Microsoft Windows Server 2003 Enterprise Edition. Different aspects of operating system security, such as number of vulnerabilities and the time to resolve them, were analyzed as indicators of security for each operating system.

whitepaper Linux Kernel Development2007-01-09 University of Waikato
  This paper gives a brief overview of the author's research into network protocols and then focuses on the process of development for the Linux kernel. This topic is approached both from a technical viewpoint and also the interactions with the open source community. The aim of the paper is for readers not to have the same difficulties the author experienced!.

whitepaper Real-World Performance of SUSE Linux Enterprise Real Time2007-01-01 Novell
  "Real Time" means different things to different people. For the purposes of this paper, real time is the ability to complete a task within a predetermined length of time - every time that task is performed - regardless of external stimuli. This paper documents the excellent results of several proof-of-concept exercises conducted with database and financial applications using SUSE Linux Enterprise Real Time. It also includes specific results of real-time tests comparing the PDL times of SUSE Linux Enterprise Real Time with Red Hat and other Linux kernels. PDL numbers are good indicators of how deterministic an operating system is. The lower the PDL number, the better real-time performance can be expected from a system in the real world.

whitepaper The Lock Hold Time Prediction of Non-Preemptible Sections in Linux 2.6.192007-01-01 Korea Advanced Institute of Science and Technology
  This paper proposed a new technique, called a Delayed Locking Technique (DLT), to improve the real-time performance of General-Purpose Operating Systems (GPOSs). The proposed technique employs the rule that entering a critical section is allowed only if the operation does not disturb the future execution of the real-time application. To execute this rule, lock hold time prediction is necessary. This paper runs four heavy workloads, tcp_sender, tcp_receiver, malloc_stress, and fork_stress, on Linux 2.6.19 and attempted to identify a set of long non-preemptible sections. As a result, they found 58 relatively long non-preemptible sections and measured the lock hold time of each section under the workloads.

whitepaper Olly! (OnLine Learning for You!): Browser Based Instant Messaging for Online Learning2007-01-01 Victoria University
  This paper outlines the design principles and software architecture of Olly! (OnLine Learning for You!). Olly! is an open source, browser based instant messaging tool designed specifically for conducting classes online. Built on the AJAX scripting model, it is crossbrowser compatible and universally available to anyone with access to a computer. Data generated by the tool (text based conversations, file uploads, etc.) is retained by the institution offering the service. While currently a prototype, the future development of Olly! will produce a release candidate for use in a variety of online learning applications.

whitepaper Demography of Linux Kernel Developers2006-12-22 Tampere University of Technology
  Several success stories of Open Source (OS) products have been seen during last decade. Due to the economical importance of the products, it is important to know who are the ones who have the largest influence to the products. Therefore, studying demography of open source projects is essential. In this paper the aspect is studied with respect to the Linux Kernel. The authors show that the influence is centered to a small number of core people, and corporates have a large impact to the development. Moreover, it enumerate the most influential companies of the Linux Kernel community. Besides influence, the authors have touched the nature of development from the point of view of the actual code.

whitepaper MessageLabs Intelligence: "Do you want spam with that spam?"2006-12-13 01:00:24 MessageLabs
  This report provides the latest threat trends for October 2006, to keep you informed regarding the ongoing fight against viruses, spam and other unwelcome content. October marks the beginning of the spam season this year in the run up to the holiday period, with MessageLabs seeing a sharp increase in levels this month, especially in the past few weeks. As predicted in the September/Q3 MessageLabs Intelligence report, spam is not going away. This increase is largely attributed to the huge rise in botnet activity over the past few weeks. There are two contributing factors compounding this issue...
