Graybox-baserade säkerhetstest : Att kostnadseffektivt simulera illasinnade angrepp

Att genomföra ett penetrationstest av en nätverksarkitektur är komplicerat, riskfyllt och omfattande. Denna rapport utforskar hur en konsult bäst genomför ett internt penetrationstest tidseffektivt, utan att utelämna viktiga delar. I ett internt penetrationstest får konsulten ofta ta del av systemdokumentation för att skaffa sig en bild av nätverksarkitekturen, på så sätt elimineras den tid det tar att kartlägga hela nätverket manuellt. Detta medför även att eventuella anomalier i systemdokumentationen kan identifieras. Kommunikation med driftansvariga under testets gång minskar risken för missförstånd och systemkrascher.

Sjötransporter : Fungerar gamla teorier om sjöfartskydd idag?

Några av de stora sjöteoretiker som vi utbildas på idag var verksamma i en tid innan insatsförsvaret, men deras teorier anses fortfarande vara användbara idag. Idag genomför svenska flottan andra typer av insatser än på slutet av 1800-talet, då teoretikerna Mahan och Corbett var verksamma. Kriget ser inte likadant ut idag och både tekniken och taktiken har utvecklats. Är de teorier vi utbildas på, tillämpbara idag? Syftet med denna uppsats är att undersöka teorier om skydd av handelsfartyg och jämföra hur detta skydd genomförs i nutid med fokus på insatsen i Adenviken.

Genuspedagogis i Förskolan

Several cities have implemented various projects to improve traffic safety in city centers.During 1970s and 1980s the city centers changed as the suburbs grew and large shopping centers were located outside the center. At the same time, several projects were initiated with construction of pedestrian streets and restriction of traffic in the center. In year 1994,shared-used areas were introduced in Sweden and these areas are often used in center environments.In Sweden, municipalities are responsible for integrating security in public places and in comprehensive plans and detailed development plans. The National Board of Housing,Building and Planning is the authority for administrating planning issues and develop general guidance about planning. Traffic is one of their key issues, although today there are no concrete guidelines from the National Board of Housing, Building and Planningfor the design of traffic safety in city centers.Traffic safety in city centers affects many people because the city center is a public place.It is therefore important that there are current guidelines available that are helpful for changes and improvements in traffic safety in the city center.The purpose of this report is to formulate guidelines for planning city centers from a traffic safety perspective.

Prim, Stadsförnyelse i Barcelona

This final project discusses renewal and upgrading of the area of Prim. It is discussed how this industrial area can be an attractive neighborhood with a varied range of services and commercial trade. Prim is located 2km north-east of the center of Barcelona. The area boarders to a deep railway valley that historically has separated Prim from its neighboring districts. At present there is almost no housing, services or commercial trade within the area and the industry is discontinued or the existing industrial buildings are derelict. There is also a lack of green recreational areas.

Utvärdering av lösningar för hårddiskkryptering

Information stored on unprotected computers that gets lost or stolen, and falls intothe wrong hands, can easily be accessed by moving the hard disk to a controlledcomputer, or by booting the computer from a removable medium, in order to getaround the operating system login. This is something that largely affects companieswhere customer information, trade secrets and other sensitive information can becompromised. A classic solution to the problem is encryption of individual files, but ithas some drawbacks as it puts a great responsibility on the users and unencryptedinformation can be left by mistake. A better solution to the problem is transparentencryption of the entire hard disk, i.e. that encryption and decryption of informationis performed automatically and without the user being affected.

DNSSEC en säkerhetsförbättring av DNS : en studie om Svenska kommuners syn på DNSSEC

Syftet med uppsatsen är att undersöka varför få svenska kommunerna valt att installera DNSSEC på sina domäner. DNS är en av de viktigaste protokollen på Internet och behövs för att sammanlänka IP-adresser med mer lättförståeliga adresser för oss människor. DNS skapades utan att tänka på säkerheten, för att kunna göra DNS säkrare utvecklades ett säkerhetstillägg till DNS detta fick namnet DNSSEC.Vi har använt oss av litteraturstudie, experiment och intervjuer för att skapa en djupare kunskap och förståelse om hur DNS och DNSSEC fungerar samt besvara varför få kommuner har valt att installera DNSSEC.Under vår litteraturstudie läste vi om flera sårbarheter i DNS och hur dessa kan utnyttjas för att utsätta en organisation för attacker såsom cacheförgiftning och MITM. Vi testade dessa sårbarheter och bekräftade det. Efter installationen av DNSSEC kunde inte angreppen längre genomföras i vår testmiljö.Under intervjuerna kom vi fram till att den vanligaste orsaken att kommuner inte väljer att installera DNSSEC är okunskap om tillvägagångsättet för en installation och att de tycker deras nuvarande DNS fungerar bra, det blir då ingen prioriterad fråga.

Riskanalys inom intrångsäkerhet på webbplatser

Attacker och intrång på webbservrar är idag vanligt förekommande. Webben gör det lätt för hackare, knäckare och andra inkräktare att hitta sårbara servrar, och det finns gott om tips att hämta för den som vill lära sig hur man gör intrång. Det finns ett flertal olika intrångsmetoder som utnyttjar olika typer av svagheter i datorsystemen. Denna uppsats inriktar sig på svagheter i webbplatsernas serverskriptsystem, dess skriptkod och konfiguration. Syftet är att undersöka huruvida intrång kan göras med endast en webbläsare via webbplatsens offentliga webbsidor. Genom att kombinera tre olika metoder - litteraturundersökning, en enkät och ett experiment - undersöker uppsatsen hur serverskriptintrång fungerar.

IT för att bygga nätverk : Att komplettera personliga relationer med IT

Globalization has lead to evolvement of teamwork between companies and their customers. One reason for this change is the growth of the IT community and the propagation of the Internet. This in turn has lead to faster communication within business networks and also a higher degree of integration between companies.The purpose of this thesis is to describe IT can be used to develop and support networks formed around IT corporations. IT also aim at describing what impact usage of IT within personal networks has on usage of IT within business networks. The thesis is limited to IT-companies using IT artifacts, not only for communication within its organization, but also communicating with its customers and other IT-companies.

Webbsystem för matprisjämförelser

This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.

FRÅN ÖPPENHET OCH NÄRVARO-TILL DISTANS OCH KONTROLL : Att medicineras och att administrera ur ett patient- och sjuksköterskeperspektiv

Title: From openness and presence to distance and control: to be medicated and to administrate from a patient and nurse perspective.Background: Within forensic psychiatric care the patients are admitted against their will, under heavy security with long term treatments. Self-care seems, based on scientific studies, to be dependent on what the nurses involved can provide. Emphasis should focus on a humane and respectful approach when the patient is exposed to coercive measures.Aim: From a patient and nurse perspective describe experiences of beeing medicated with and to administrate antipsychotic drugs within the psychiatric inpatient care.Method: Interviews with patients and nurses, which were analyzed using qualitative content analysis with an inductive approach.Results: Patients experience frustration over not beeing able to participate in or influence descisions made regarding their neuroleptic treatment. The neuroleptic treatment is described as a coercive measure and is characterized as an experience of losing control and independence. Nurses? experiences of administering antipsychotics were described as having to do what is needed for the long term benefit of patients? well-being.

Remburser och andra säkerhetsarrangmang vid internationell handel

AbstractWe live in a world today that is characterized by the Internet. We can get hold of people on the other side of the globe whenever we want and we can purchase what ever we want, from who ever we want, anytime we want. This development has made it important to find systems of dealing with the payment in a safe and secure way, both for a private person as well as for a company, when you do transactions with people far away, and those systems is the core of this essay. As a private person you sometimes need to transfer money to family members who live abroad and you can then use clean payments. This means that banks all over the world has systems which makes it easier when their customs wishes to transfer money abroad.

Liv i den övergivna trädgården? : Tro och sekularisering i Sverige, speglad mot dominerande teorier om sekulariseringsprocesser

This master thesis summarizes contemporary theories on secularization processes in the Western world, and compares these with the example of Sweden, which by many scholars is considered to be the most secularized country in the Western world.I do this by dividing the most influential theorists in five different groups. In each group I explain how the theorists formulate and motivate their positions. These groups are:1) The secularization paradigm, where secularization always accompanies modernization. (Therorists: Steve Bruce and Peter Berger (in the 1960s)2) The paradigm basically accepted, but revised to depend on existential security, rather than modernisation as such. (Pippa Norris and Ronald Inglehart)3) Religion returned in the public sphere.

Generationsskifte : Särskilt om gåva och blandade fång

All small- and medium-sized family owned enterprises need to sooner or later undergo a change of ownership. When the elder generation is approaching their retirement they have to make a choice; either hand over the business to the younger generation or sell it to an outsider. The succession of the family owned business can create a life long dilemma for the entrepreneur. From the view of taxation there are, according to current legislation, no reasons to plan the succession to the younger generation. If no preparation has been done, the optional law system concerning inheritance will divide the property left.

Ekonomiskt bistånd : Ett geografiskt lotteri?

Denna studie syftar till att granska variationer i bedömningar och beslut om ekonomiskt bistånd utifrån vilken betydelse den enskilda organisationens riktlinjer har för dessa. Utifrån syftet, och med stöd av tidigare forskning på området, valdes vinjettstudien som metod. Ett identiskt typfall, gällande en fiktiv ansökan om ekonomiskt bistånd, skickades ut till samtliga kommuner i Västra Götalands län, med undantag för Göteborgs kommun. Vinjetten riktades till socialsekreterare som i sin vardag arbetar med handläggning av ekonomiskt bistånd och totalt erhölls svar från 16 olika kommuner. Resultatet påvisar stora skillnader i både bedömningar och beslut mellan de olika kommunerna vilket verifierar de tidigare studier som gjorts.

Journalistik på liv och död En kvalitativ studie om journalisters syn på medias roll i asylprocesser!

The main purpose of this thesis is to explore journalists? views of the role of journalism in the asylum processes. The potentially problematic phenomenon is growing, and its spread will affect the way publishing decisions are made in the future. The subject is new and foreign to many journalists, and little to no research has previously been done on the subject. Our study will therefore provide new insight in the field of journalism ethics.We have conducted a qualitative study based on interviews with eight Swedish journalists who in oneway or another have reported on threatened asylum seekers.
