Topology-aware vulnerability mitigation wormsAl-Salloum, Ziyad January 2011 (has links)
In very dynamic Information and Communication Technology (ICT) infrastructures, with rapidly growing applications, malicious intrusions have become very sophisticated, effective, and fast. Industries have suffered billions of US dollars losses due only to malicious worm outbreaks. Several calls have been issued by governments and industries to the research community to propose innovative solutions that would help prevent malicious breaches, especially with enterprise networks becoming more complex, large, and volatile. In this thesis we approach self-replicating, self-propagating, and self-contained network programs (i.e. worms) as vulnerability mitigation mechanisms to eliminate threats to networks. These programs provide distinctive features, including: Short distance communication with network nodes, intermittent network node vulnerability probing, and network topology discovery. Such features become necessary, especially for networks with frequent node association and disassociation, dynamically connected links, and where hosts concurrently run multiple operating systems. We propose -- to the best of our knowledge -- the first computer worm that utilize the second layer of the OSI model (Data Link Layer) as its main propagation medium. We name our defensive worm Seawave, a controlled interactive, self-replicating, self-propagating, and self-contained vulnerability mitigation mechanism. We develop, experiment, and evaluate Seawave under different simulation environments that mimic to a large extent enterprise networks. We also propose a threat analysis model to help identify weaknesses, strengths, and threats within and towards our vulnerability mitigation mechanism, followed by a mathematical propagation model to observe Seawave's performance under large scale enterprise networks. We also preliminary propose another vulnerability mitigation worm that utilizes the Link Layer Discovery Protocol (LLDP) for its propagation, along with an evaluation of its performance. In addition, we describe a preliminary taxonomy that rediscovers the relationship between different types of self-replicating programs (i.e. viruses, worms, and botnets) and redefines these programs based on their properties. The taxonomy provides a classification that can be easily applied within the industry and the research community and paves the way for a promising research direction that would consider the defensive side of self-replicating programs.

Biological and Molecular Characteristics of Microorganism-Stimulated Defence Response in Lycopersicon esculentum –LAttitalla, Idress H. January 2004 (has links)
Microorganisms, including two fungi, Phytophthora cryptogea and Fusarium oxysporum strain Fo-(IMI 386351), and one bacterium, Pesudomonas sp. strain MF30, were tested for their abilities to stimulate plant defence responses in tomato (Lycopersicon esculentum –L.) and to serve as effective biocontrol agents (Bs). The study included in vivo and in vitro characterization of biological attributes of the microorganisms, pertaining to their abilities to stimulate plant immunity against a fungal pathogen, Fusarium oxysporum f. sp. lycopersici (Fol), the causal agent of tomato wilt disease. Using Lycopersicon esculentum –L. as a model plant for examining some fundamental elements of the plant-microorganism interaction, the study reveals and clarifies some aspects of the close association and the complexity of such systems. For each B, the results revealed a B-distinct plant-microorganism interaction, which included systemic induced resistance (SIR). A phylogenetic analyses of the partial sequences of two Fo-(IMI 386351) genes, a mitochondrial small subunit ribosomal DNA (mtSSU rDNA) and the nuclear translation elongation factor 1α (EF-1α), provided phylogenetic trees confirming that Fo-(IMI 386351) might be a member of Fol or of F. oxysporum f. sp. melonis, which have polyphyletic evolutionary origins. RFLP analysis (mtDNA), suggested that Fo-(IMI 386351) probably belongs to Fol. For routine and accurate differentiation between two morphologically indistinguishable F. oxysporum formae speciales strains, F. oxysporum f. sp. lycopersici and F. oxysporum f. sp. radicis-lycopersici, a molecular method (mtDNA RFLP analysis) was developed, and its usefulness for such differentiation was compared with that of two other methods: isozyme analysis and an osmotic method, revealed with high performance liquid chromatography (HPLC). The HPLC-spectra of Fo-(IMI 386351) had an extra peak for the two tested fractions, indicating that activation of the observed plant defence mechanism could have been at least partially the result of one of the products of the eliciting microbe. Preliminary results obtained by nuclear magnetic resonance spectrometry of those fractions suggest that the extra peak probably represents an oligosaccharide, which may have acted as a mobile signal and triggered the plant defence mechanisms. We concluded that (1) our three tested microorganisms are able to stimulate plant defence mechanisms by triggering SIR (plant immunity), (2) the complexity and elaborateness of evolved plant-microbe interactions involving plant defence can, at least in some cases, be observed and studied in the laboratory, and (3) molecular tools can be a powerful means for identifying fungal strains and for clarifying their taxonomical relationships.

Asmens neturtinių teisių apsaugos plėtimąsi lemiantys veiksniai ir problematika / Factors which determine the widening of the protection of personality rights and problematicMieželytė, Renata 22 January 2009 (has links)
Šiandien Europos valstybių teismų praktikoje pastebima tendencija plėsti asmens neturtinių teisių apsaugos lygį. Kai kuriose Europos valstybėse – Vokietijoje, Austrijoje, Nyderlanduose – atsisakoma tradicinių teisinio reguliavimo modelių, ribojančių galimybes taikyti tam tikrus civilinių teisių gynimo būdus asmens neturtinių teisių pažeidimo atveju. Plečiasi neturtinės žalos atlyginimo, kaip civilinių teisių gynimo būdo, taikymo sritis. Europos Žmogaus Teisių Teismo, nacionalinių teismų praktikos ir įstatymų leidžiamosios valdžios pagalba Europos valstybėse plečiamas teisės saugomų neturtinių vertybių sąrašas. Ypatingas dėmesys skiriamas asmens neturtinėms teisėms, susijusioms ne su fiziniais, o su vidiniais, psichologiniais individo parametrais. Plečiantis asmens neturtinių teisių spektrui kyla asmens neturtinių teisių tarpusavio konkuravimo problema: kaip turi būti derinamos lygiavertės, tarptautiniu ir konstituciniu lygmeniu įtvirtintos asmens neturtinės teisės, kad būtų garantuota veiksminga šių teisių apsauga?
Tyrimo tikslas – išskirti ir plačiau aptarti pagrindinius veiksnius, lemiančius asmens neturtinių teisių apsaugos plėtimosi dinamiką ir mastą bei akcentuoti aktualiausias asmens neturtinių teisių apsaugos problemas.
Pirmoje magistro baigiamojo darbo dalyje nagrinėjama asmens neturtinių teisių apsaugos samprata, aptariamos valstybės saugomos neturtinės vertybės, jų gynimo ir teisės pažeidimų prevencijos galimybės.
Antroji dalis skirta išskirti ir aptarti veiksnius... [toliau žr. visą tekstą] / Nowadays, it is a tendency in European countries to widen the scope of protection of personality rights. In some countries, such as Germany, Austria, Netherlands, the traditional models of legal regulations, which restrict a possibility to invoke certain means of civil protection regarding the cases of infringement of personality rights are repudiated. The scope of application of non-pecuniary damage as a means of civil defense is being developed. European Court of Human Rights case-law, national court case-law and legislative authority – all have a great influence on developing a list of personality rights which is closely related not to physical, but to interior and psychological parameters of individual. The widening scope of protection of personality rights the main problem rise in competing in between with the rights themselves – how to find a fair balance between the equivalent rights which are ordained on the constitutional and international level in order to guarantee the effective protection of the personality rights.
The aim of the analysis is to characterize and analyze the main factors in more detail, which determine the scope and dynamics in the protection of personality rights, and to emphasize the problems of the protection of personality rights.
In the first part of the master thesis the author analyses the conception of personality rights, discusses the main state protected values, and the means of how to defense them as well as the possibility to prevent... [to full text]

Memories of the Border War: An Interpretive Analysis of White South African Defence Force Veteran Perspectives, 1966-1989Graham, Danielle 16 August 2012 (has links)
Through their stories, South African Defence Force (SADF) veterans of the Border War participate in the historical revival of South Africa’s involvement in the Angolan conflict, 1966-1989. Their engagement in the Border War discourse sets these veterans apart for an analysis of their motivations to participate and how their views compare and contrast with one another. SADF veterans are reconstructing their past within their present context in the new South Africa. Their struggle to rectify public knowledge and perceptions of the past through the provision of their personal memories is a growing trend within South Africa, one that has become a conversation between the various competing narratives.

Apeliacijos esmė ir santykis su teise į teisminę gynybą / The essence of appeal and its relation to the right to judicial defenceMarcalytė, Paulina 05 February 2013 (has links)
Teisminė gynyba – instrumentas asmens pažeistoms ar ginčijamoms teisėms ir teisėtiems interesams ginti. Ši teisė yra aktuali ir problematiška dėl ginčo ir teisminio proceso ypatumo – priešingų šalių interesų buvimo, be to, savo interesą turi ir valstybė (visuomenė), kadangi teismų sistema reikalauja didelių finansinių, žmogiškųjų, laiko išteklių. Šio mokslinio tyrimo aktualumą lemia ne vien substancinio pobūdžio priežastys. 2011 m. birželio 21 d. priimtas įstatymas, kuriuo pakeista nemažai Lietuvos civilinio proceso kodekso nuostatų (dažnai vadinama civilinio proceso reforma), įskaitant procesą apeliacinės instancijos teisme reguliuojančių teisės normų, be to, principinių, apibūdinančių šį institutą, apeliacijos teisės reikšmę civiliniame procese. Pastarąjį dešimtį ar net pastaraisiais metais kai kuriose valstybėse pasikeitė apeliacijos esmė, tačiau kitose, priešingai, išlaikoma apeliacijos suvokimo ir teisinio reguliavimo tradicija. Visa tai nulėmė poreikį įvertinti savąją apeliacijos esmę bei nustatyti kokios priežastys lemia apeliacijos reformas.
Autorė šiame darbe siekė išspręsti apeliacijos esmės problemą ir darė prielaidą, kad problema per se nelaikytina problema, jos išsprendimas turi duoti teigiamą rezultatą ir būti paspirtis tolimesniems tyrimams. Išanalizavusi teisę į teisminę gynybą ir apeliaciją, autorė ieškojo teisės į teisminę gynybą ir apeliacijos santykio išraiškos, analizavo ir persvarstė kai kuriuos civilinio proceso moksle įprastais tapusius argumentus... [toliau žr. visą tekstą] / On the 21st of June 2012 a law has been adopted by which Lithuanian Code of civil procedure was amended significantly (the amendment so–called “the reform of civil procedure”), including regulation of procedures in instance of appeal. This motivates to analyze and make revaluation of essence of appeal in Lithuania. The analysis is also needed because in past decade and even past few years many of European countries have totally reformed their appeal systems. However, legal regulation amendments are not the only matter which causes the relevancy of appeal and its relation to the right to judicial defence. There are some substantial reasons, e. g. dispute and civil procedure in their nature have contrary interests of parties, moreover, the state and society has interests which do not comply with interests of parties. This is caused by consumption of financial, time and human resources.
There are various papers and theses on the right to judicial defence and appeal, but, to take note, the object of them differs from the essence of appeal and its relation to the right to judicial defence or, moreover, is fragmental – focused only on the restrictions related to limits of appeal by the value of dispute (which is already abolished) or other fragmental subjects.
The result of this work demonstrates that the essence of appeal in Lithuania is to be described as the instrument to control the legality and reasonability of the courts of first instance decisions. Appeal in Lithuania is to... [to full text]

A waste management and sanitation audit of the South African National Defence Force in rural deployments in Maputoland : a case study.Varaden, Roshni. January 2004 (has links)
ant national legislation on the disposal of waste and waste disposal sites has been promulgated to regulate the dumping of unwanted materials. This development poses major legal compliance problems for the South African National Defence Force (S.A.N.D.F.) deployments in rural areas. The absence of municipal services to these areas and the unavailability of municipal dumpsites do not facilitate adherence to legislation. The development of an integrated waste management system for Defence represents an attempt to ensure compliance with national legislation. An overview and assessment of current waste management practices in the S.A.N.D.F. is provided in this document. The literature review focussed on the theory of waste management, the current situation with regard to sanitation in rural areas and a review of pertinent legislation, and provided the foundation for the development of questionnaires. The study then explored aspects of waste management and sanitation that were taken into consideration in preparing for operations . Data collection entailed interviews with senior members of the S.A.N.D.F. who are responsible for the planning of such projects. Thereafter an investigation was conducted into the waste management practices employed during deployments to rural areas. Data collection in this respect involved the administration of questionnaires to soldiers at temporary bases and during patrols, as well as an audit of the waste generated at the temporary bases, noting how refuse was managed under these conditions. These methods of primary data collection included interviews with various government and non-government officials. Interviews with senior members of the S.A.N.D.F. revealed that the planning and preparation for operations are core-function focused and that the integration of waste management and sanitation in the planning process is minimal and inadequate . The data obtained from questionnaires administered to the soldiers revealed that current waste management practices at the temporary bases and during patrols are considered to be satisfactory to the soldiers, as they are of the opinion that "we are doing the best we can under such circumstances". The waste audit revealed that ninety-eight percent of the waste generated in the study area is recyclable. Consequently, this study recommends that waste management methods be integrated into the planning process. Furthermore it is recommended that environmental education be included as a compulsory module during basic training and re-training for all members of the S.A.N.D.F., i.e. from senior management down to the most junior level. A long-term solution to improve on the current waste management practices is recycling. With regard to sanitation, the Director of Sanitation of the Department of Water Affairs and Forestry (D.W.A.F.) suggested that relevant members of the S.A.N.D.F. meet with members of D.W.A.F. and the Umkhanyakude Regional District Council, to discuss the inclusion of the S.A.N.D.F. in the current sanitation-provision projects in the study area. Short-term solutions were that the S.A.N.D.F. liaise with the G.I.S. section at D.W.A.F. This section will be able to provide the S.A.N.D.F. with information on the location of boreholes and hand-pumps (the only source of drinking water for the local population). The S.A.N.D.F. must ensure that waste disposal sites and field toilets, commonly referred to as go-karts, are located away from these water sources and, whenever possible, on higher ground. / Thesis (M.A.)-University of KwaZulu-Natal,Durban, 2004.
