Academic literature on the topic 'Microsoft Attack Surface Analyzer'

Based on the current development of corneal endothelial cells in the domestic, this paper developed corneal endothelial cell analyzer software system which taken Microsoft Visual Studio as development platform in Windows7 system and combined with MATLAB image processing technology and the Access database information management technology. The software relies on a database established patient archiving and query system, by VC + + statically call the dynamic link library that MATLAB Compiler generated to complete image processing, by partial equilibrium approach for image enhancement, by dynamic difference method for determination threshold when binaries. The software provides good interactive interface and graphics display surface, but also sets aside network port as follow-platform extension.

Since the distribution of anthrax causing spores through the U.S. Postal System in the autumn of 2001, bioterrorism has become an ever present threat. During and following an attack it is also important to detect spores on surfaces, to assess the extent of an attack, to quantify risk of infection by contact, as well as to evaluate post-attack clean-up. To perform useful measurements, analyzers and/or methods must be capable of detecting as few as 10 spores/cm2, in under 5-minutes, with little or no sample preparation or false-positive responses, using a portable device. In an effort to develop such a device, we have been investigating the ability of surface-enhanced Raman spectroscopy (SERS) to detect dipicolinic acid (DPA) as a chemical signature of bacilli spores. In general, SERS is capable of detecting mg/L concentrations and lower, and providing unequivocal identification of chemicals based on each one's unique spectrum. However, rapid analysis requires extracting the DPA from the spores for SERS detection. Here we describe the use of a room temperature digesting agent in combination with SERS to detect 220 spores on a surface, the entire procedure which was performed in 2.5 minutes.

Scanning tunneling microscopy (STM) was used to elucidate monolayer etch pits that form on highly oriented pyrolytic graphite (HOPG) heated in an electrothermal analyzer. Pits form at elevated temperatures due to reactions between oxygen and exposed carbon edge atoms (defects) and additionally with intraplanar carbon atoms (through abstraction). Samples of HOPG without analyte or matrix modifier were placed in the depression of a pure pyrolytic graphite platform and heated by using standard analysis furnace programs. Under argon stop-flow conditions, pits form in less than a second at atomization temperatures equal to and above 1200 °C. With low argon flow rates (40 mL/min), pits formed at atomization temperatures equal to and greater than 1750 °C in less than a second. Quantitative pit formation rates were used to indicate oxygen partial pressure, which may be as high as ∼ 10−3 atm at 1200 °C. Reaction rates were used to predict surface degradation due to oxygen attack and determine that 1-μm depth normal to the surface would be removed by 200 successive 5-second-period furnace firings at 1200 °C. Implications for increases in surface reactivity and analyte intercalation are discussed.

This research deals with the synthesis of nanosized copper as colloidal solution and its application to cotton fabric. Copper nano colloids were prepared by chemical reduction of copper salt using sodium borohydride as reducing agent in presence of tri-sodium citrate. The size and size distribution of the particles were examined by particle size analyzer and the morphology of the synthesized particles was examined by SEM and AFM techniques. X-ray fluorescence spectroscopy detected the presence of copper in the treated fabric. The results of particle size analysis showed that the average particle size varied from 60 nm to 100 nm. The nano copper treated cotton was subjected to soil burial test for the assessment of its resistance towards microbial attack. SEM images of treated fabric indicate copper nano particles are well dispersed on the surface of the specimens. The treatments of nano copper colloidal solution on cotton not only improve its antimicrobial efficiency but also influenced the tensile strength of the fabric sample positively. The treatment was found to enhance the color depth and fastness properties of direct dyed cotton fabric samples.

I consider that the golden rule requires that if I like a program I must share it with other people who like it. Software sellers want to divide the users and conquer them, making each user agree not to share with others. I refuse to break solidarity with other users in this way. I cannot in good conscience sign a nondisclosure agreement or a software license agreement. Richard Stallman (GNU Manifesto) There is much more to Stallman’s Manifesto […] Suffice it to say that on the surface, it read like a socialist polemic, but I saw something different. I saw a business plan in disguise. Michael Tiemann (72) The current discourse surrounding the rapid development and deployment of “free” and “open source” software and operating systems is framed by an undeniably utopian impulse. The “openness” of open source software is informed by concerns both practical (freedom from oppressive software production and licensing/copyright schemes) and ideological (the valorisation of anarchic organizational forms, communal production, and public property rights). The utopian impulse that underwrites this discourse is important for many reasons, but what I want to trace here is the trajectory from ideological position to practical action as it relates to differing forms of utopianism. The initial anarcho-socialist utopian move initiated by Richard Stallman’s GNU (GNU’s Not UNIX) Project and Free Software Foundation (FSF) is currently being transformed into an organizational utopia in the form of the Open Source Movement (OSM). The purpose here is not to take sides in the philological/philosophical debate over the definitions and relative merits of “free” versus “open source” software or to lament the passing of a missed opportunity, but to address the intimations of hope and deprival (with apologies to Grant) that can be gleaned from the relationship between utopianism and socio-technological practices. The popularity of open source development ideals and practices indicates a certain dissatisfaction with corporate technoculture on the part of some (many?) of those who work in these institutions. This dissatisfaction is clearly evident in Richard Stallman’s GNU Manifesto wherein he critiques the shift from public domain to copyrighted software development that has occurred in the last three decades. Recalling Brian Winston’s theorization of technological development, the move toward copyrighted software appears to have come as a result of the increasing diffusion of computing hardware in the 1980’s and the practical realization of software development as an economically rationalized for-profit enterprise. Prior to the broad commodification of software, programmers shared knowledge and code without worrying about software licenses and copyrights, institutionally commodified intellectual property, and non-disclosure agreements (at least according to Stallman’s experience). Stallman’s heroic effort to create the GNU system is thus not only a direct attack on commodified software production, but a consciously utopian attempt to recapture the “open” communal programming practices that existed during the 1960’s and 70’s. The utopian impulse found in this open form of software development is significant precisely because it underwrites recent efforts to reject current copyright regimes and, by extension, techno-industrial oligarchies. This potential is enabled by newly available forms of grassroots software development (code sharing and development via the Internet being the most obvious example). Stallman introduced and encouraged a licensing system that expressly prohibited the copyrighting of software developed using GNU software protocols and standards (termed “copyleft”). The lag between the initial deployment of Stallman’s early software efforts and their uptake by the wider computing community came as increases in computer literacy, technology markets, affordable personal computing power, and broadband CMC networks came along in the 1990’s. The OSM’s recent mobilization around Linux continues and parallels Stallman’s efforts via the adoption of the GNU license and copyleft. While the hallmarks of Stallman’s communal software production system remain, the overall nature of Open Source software is framed by a rather different notion of utopian openness than is evident in Stallman’s manifesto. This brings me to the broader notion of an anarcho-utopianism framed by what Bookchin has identified as the twin goals of individual liberty and social democracy. Claims are already being made that practices related to open source software development and its emergent virtually interconnected organizational form may provide the basis for (re)imagining systems of social governance while simultaneously providing the practical infrastructure by which these new forms may be manifested: The experience of open source development, or even just the acceptance of its value as a model for others, provides a real-life practice for the deeper change in perspective required if we are to move into a more networked and emergent understanding of our world. The local community must be experienced as a place to implement policies, incrementally, that will eventually have an effect on the whole. (Rushkoff 61) Suggestions that the FSF’s and OSM’s methods of software development may serve as a model for more open and democratic policy making resonates with political theory in general, and social democracy and anarchism in particular. But neither the OSM nor the FSF is a political platform. They are simply modalities of software production which find their foundations in communal forms of decision making, intellectual labour, and dissemination. A utopian impulse is nonetheless revealed in the typically vague invocations of political anarchism and social democratic ideals that accompany the discursive promotion and legitimization of these modalities. The FSF advocates a broadly social anarchistic approach allied with a desire to overturn entirely commodified software production. The OSM, on the other hand, is more concerned with a kind of lifestyle anarchism that focuses on increasing programmer and user freedom within existing frameworks of software production and use. For Bookchin, the latter form of anarchism is positive insofar it advocates individual liberty, but it ultimately undermines the broader goals of anarchism by focusing on transient notions of individualism. The result is a situation wherein “the word anarchy will become part of the chic bourgeois vocabulary of the coming century — naughty, rebellious, insouciant, but deliciously safe” (3). It is interesting to note in passim the various discursive entanglements of anarchism and the Internet that have occurred since 1995, the time of Bookchin’s statement. The utopian discourse that weaves its way through the non-technical discussions surrounding GNU, Linux, and other Open Source projects is certainly strong, but it begs the question of exactly what kinds of utopias are being offered ? Henri Lefebvre was rather suspicious of utopian thought because it is so frequently allied with efforts to legitimize nationalistic and totalitarian organizational practices. While suggesting that utopian thought was useful, he would only go so far as to warn that any such thought must avoid notions of a revolution that would simply substitute one state-sanctioned form of organized production with another, arguing instead for a “transformation of society [that] presupposes a collective ownership and management of space [we could say “society’ or even “software” here in place of “space] founded on the permanent participation of the ‘interested parties’, with their multiple, varied and even contradictory interests” (422). For Lefebvre, any useful form of utopianism is not a matter of coming up with alternative state apparatuses, but of somehow creating the conditions through which an open orientation to future possibilities might allow for the foundation of a more socially democratic society. The FSF comes closest to fulfilling this ideal—at least within the realm of computing—insofar its attendant communities are involved less in the creation of a new institutional form than in the propagation of practices and desires for more open forms of software development. As such, the FSF seems to deploy the kind of utopian thinking and practice that Lefebvre finds useful. There is hope (social and computational) in this kind of utopian orientation because its socio-institutional functioning is left forever open-ended by way of its locating productive practices in communal formations. The FSF offers an idealized mode of communally open software development while refusing to provide an overarching and institutionalized organizational form by which it is to be utilized. Borrowing heavily from the FSF’s ideals and practices, the OSM’s efforts to integrate practices of communal software development into contemporary techno-capitalism is not simply an intimation of deprival — a moment to lament the passing of the FSF’s utopian ideals — rather, the OSM constitutes what Deleuze and Guattari refer to as a moment of actualization whereby the virtual (and utopian) potential future(s) of communal software development cross the practico-material threshold to become manifest practices. Stallman’s GNU existed in the rather rarefied realm of hardcore coders for years before Torvald’s Linux took open/free software principles into the mainstream. The moment of actualization was not simply technical (available hardware, software, programmers, networks, etc.): it was the recognition that communal “copylefted” programming could “find a place” in the everyday structures of IT industries, services, and markets. It is the moment when Tiemann sees a business plan in Stallman’s “socialist polemic”. At this point that the utopian orientation and ideals promoted by the FSF transforms into an organizational utopia spearheaded by the OSM. The debate over this transformation shows few signs of abating any time soon. Stallman feels that Eric Raymond’s (the spiritual “leader” of the OSM) promotion of a potentially massive, and certainly for-profit, industry founded on the implementation and support of open source software defeats the basic (utopian) principles of free software. Echoing Bookchin’s concerns about lifestyle anarchism, Stallman worries that the OSM will simply result in the re-introduction of all of those things that drove him out of institutional software development in the first place: “the rhetoric of ‘open source’ focuses on the potential to make high quality, powerful software, but shuns the ideas of freedom, community and principle” (1999:70) . The FSF’s social utopianism thus appears to provide the productive content, but not the political form, for the more practically minded utopianism of the OSM, which offers an organizational utopia more akin to the “substitutive” utopias disavowed by Lefebvre. As Martin Parker argues, utopian thought and practice tends to be organizational in nature: “most, if not all, fictional and actual utopias rely on a re-formulation of principles of social order. They are in that sense organized, though often on different principles to the market managerial hegemony” (217-218). Stallman’s open anarcho-utopianism commits to an avoidance of market managerial hegemony. The OSM, however, not only cooperates with market hegemony, it seeks to find a place within it. This is a crucial difference. The openness introduced by the FSF is incorporated by the OSM only at the level of software production itself, thus containing and integrating its communal practices in the service of existing market needs and structures. The OSM is thus likely only a threat to Microsoft, and this only because it proffers a new business model. Indeed, the popular appeal of the OSM’s version of open source as a metaphor and model for businesses suggests that it may be an easily, and safely, appropriated set of practices. On the other hand, the FSF’s promotion of a more “socialist” approach to software production and use is based on the same basic programming practices and it will therefore be rather difficult to exact some sort of industrial control of copyright and/or intellectual property where open source software is concerned. Whether or not these two approaches are compatible, or if users will push their development into as yet unseen directions, is by no means clear at this point. With open source development poised on the verge of being the “next big thing”, the manifest expression of its anarchic utopian impulse in the form of treatises and essays is somewhat limited insofar as the community is primarily composed of programmers rather than social theorists. Nevertheless, the utopian impulse is becoming more clearly expressed where it perhaps matters most: as an emergent set of practices in the domain of software production and use. The “kernel” of openness introduced by both the FSF and the OSM thus needs to be addressed in detail, and sooner rather than later, because it is in the struggle between these two forms of anarchic utopianism that the broader sociopolitical implications of a radically different form of software production will be played out.

This thesis endeavors to determine the feasibility of design metrics as a predictor of attack surface size by finding a positive correlation between one or more design metrics and an application’s attack surface measurement. An attack surface is the set of ways in which an adversary can enter a system and potentially cause damage. For an experimental setting, six open-source java-based projects were analyzed. For each project, the attack surface is assessed using Microsoft’s Attack Surface Analyzer, which takes a snapshot of a system state before and after the installation of product(s) and displays the changes to a number of key elements of the Windows attack surface. A collection of design metrics was collected from each open-source project as well. The goal is to find a metric or set of metrics that predicted the attack surface changes identified by the Attack Surface Analyzer.
