Nätverkssäkerhet med IPS : Förbättrad nätverkssäkerhet med Intrusion Prevention Systems

Att skydda sin IT-miljö mot olika typer av intrång och attacker som till exempel trojaner,skadliga Java applets eller DoS attacker med hjälp av brandväggar och antivirusprogramär två viktiga lager i skalskyddet.I den här uppsatsen undersöks hur väl ett Intrusion Prevention System skulle kunna fungera som ett ytterligare lager i skalskyddet. Fokus ligger på hur väl IPS-systemet klarar av att avvärja attacker, hur mycket tid som går åt till konfigurering och drift för att få ett fungerande IPS samt hur prestandan i nätverket påverkas av implementationen. För att mäta hur väl IPS systemet klarar av att upptäcka och blockera attacker utförs två experiment där ett mindre nätverk attackeras på olika sätt. I det första experimentet skyddas infrastrukturen av en brandvägg och klienterna är utrustade med antivirusprogram. I det andra experimentet genomförs samma attacker igen fast med ett Snort IPS implementerat i nätverket.Resultatet av de genomförda experimenten visar att en IPS klarar att blockera ca 87% av attackerna, men nätverksprestandan påverkas negativt.

Att ställa den skyddsbehövande inför rätta : Om de rättsliga förutsättningarna för att förhindra skyddslöshet vid tillämpningen av Flyktingkonventionens uteslutandeklausuler och samtidigt motverka straffrihet för de grova folkrättsbrott som faller under k

The purpose of this study has been to investigate the prospects for identifying and prosecuting individuals suspected of war crimes, within the process of exclusion from refugee status under article 1F(a) of the 1951 Refugee Convention, and using subsequent mechanisms for extradition or prosecution in international criminal law. A number of principles within human rights law and public international law have been advocated by the UNCHR and several human rights NGOs as necessary for a thorough application of the exclusion clauses; one that takes individual responsibility into account and upholds the aims and purposes of the exclusion clauses. There is a discussion as to whether specialised or accelerated exclusion procedures are justified for reasons of security and efficiency, or if they put the rights of the individual at risk and limit the opportunities for gathering information to support investigation and prosecution of the crime in question. Apart from the instruments of asylum law and procedure that have emerged within the EU harmonisation process, there are no general, binding rules on the procedural aspects of the exclusion clauses. One principle that regulates the consequences for the individual of exclusion from refugee status and decisions on extradition is, however, the principle of non-refoulement.

Användning av datorns grafikkort för beräkningar med användning av OpenCL (Open Computing Language)

SAAB Security and defense solutions i Järfälla har ett system som används av militären för övervakning av flygplan. Systemet visar på en datorskärm en karta över Europa där flygplanen visas med markeringar från data som samlats in av radars. Då data samlas in med en låg frekvens visas ytterligare en markering som kallas målspår. Dessa målspår beräknas fram med tunga matematiska beräkningar och sköts av datorns processor.Det finns ett önskemål om att flytta dessa beräkningar till datorns Grafikkort med hjälp av OpenCL och därmed frigöra processorns resurser. OpenCL har implementerats med två olika Java bindings och prestandaskillnader mellan dessa samt de ursprungliga beräkningarna har undersökts.

Från SPPB till SUB. En bibliotekssammanslagning och dess konsekvenser ur ett användarperspektiv

The Swedish working-class author Ivar Lo-Johansson (1901-1990) wrote a collection of one hundred short stories between the years 1968-1972. His other productions, generally speaking, have partially different social reform purposes, but, according to himself, these short stories were written with the intention to be totally free of tendencies (even though he himself doubted that he succeeded with this).During the same period that these short stories were published, the Swedish social democrats were under the challenge of radical movements that, mainly on the radical left?s ideological foundation, had a relatively strong influence in Sweden, among other countries, from the mid 1960?s to the late 1970?s. Since Lo-Johansson mainly seemed to have supported the politics of the social democrats, the purpose of the investigation in this thesis has been to see if he ? in the three short stories: Vikingakärlek (1970), Rikslögnaren (1971) and Ansgars resa till Sverige (1972) ? is conveying an ideological use of history and basic political values that were used by the social democratic party during this time period.

Småhusproduktion : Utvecklingsmöjligheter hos JM AB

The Swedish building contractor JMRegion Öst would like to to investigatethe possibilities of developing andstreamlining the production of singlefamilyhouses. JM are producing singlefamilyhouses with prefabricated framesat a rate of about two houses per week.During construction, the different tasksare performed by JM?s own productionstaff but also by varioussubcontractors.When examining the schedules of recentlyproduced projects, it appears that allthe houses are more or less completedeight weeks before the customer moves into the house. During those eight weeksseveral operations are conducted such asinspections, installation of appliancesand cleaning procedures. The inspectionperiod constitutes between 25 and 35% ofthe complete construction period.By conducting interviews, it has beendiscovered that this final phase is anessential security buffer for delays anderrors that often occur.

Statlig sjöfart för maritim säkerhet : och hur ser Försvarsmaktens roll ut?

Den statliga sjöfarten idag är ett område med många inblandade myndigheter och en oklar uppgiftsfördelning. Det är även svårt att se hur väl organiseringen av den statliga sjöfarten är uppbyggd för att klara en kris eller ett krig. Syftet med uppsatsen är att undersöka hur effektiv den statliga sjöfarten är vid en kris, hur väl kraven för maritim säkerhet uppfylls och hur försvarsmaktens roll i den statliga sjöfartenI formen av en fallstudie med en teoretiskt deduktiv ansats och en kvalitativ textanalys appliceras Graham Allisons organisationsteori och teori om maritim säkerhet på den statliga sjöfarten. Empirin är i form av förordningar, instruktioner och reglerbrev som är ställda på respektive myndighet.Undersökningen visar att dagens organisering av den statliga sjöfarten inte är optimal för att verka vid en kris och kraven för maritim säkerhet uppfylls, men förbättringspunkter föreligger. En slutsats är att en närmare samverkan mellan myndigheterna skulle lösa många av de problem som idag existerar.

Jacobsberg - Lustträdgård och begravningsplats : En dokumentation, trädgårdshistorisk studie och funktionsanalys

This essay, Jacobsberg ? a Landscape Garden and a Cemetery is a documentation and a historical analyze where I?ve been focusing on the development of the landscape garden in Sweden in relation to a garden called Jacobsberg. The garden was built close to Visby on Gotland in the early 1800s by the assessor Jacob Dubbe, but has since been almost forgotten. My survey aims to depict the circumstances surrounding the creation of Jacobsberg. In what purpose was it built? I?ve also been examine the historical context of the garden?s origins with the intention to define and confirm its architectural style.The essay comprises two major parts, where the first part deals with the history behind Jacob Dubbe and Jacobsberg, and contains an illustration of the assessor?s life and of the garden?s original structure and shape.

Att göra främlingar. Nation och sexualitet i dagens ryska homofobiska narrativ.

The topic of homosexuality was until recently a taboo in Russian public discussion, but has during the last years become a hotly debated issue. Analyzing what I call the new homophobic narrative I isolate and examine two ways of ?othering? homosexuals, constructing them as strangers, when sexual minorities are discussed in today´s Russia. Sexual deviants are portrayed as threats to the nation and are connected to the West and its influence. Using analytical tools from queer theory, security studies and postcolonial approaches I discuss different ways of configuring the relation between nation and sexuality, identities that are interwoven in the homophobic narrative.

Lämplighet i familjehem : En kvalitativ studie av godkända familjehemsutredningar

The focus of this thesis is on what is considered to be a suitable foster home. For the study to be carried out an application had to be made to get access to the foster home assessments in a medium-sized municipality in Sweden. With the support of attachment theory and theory of standards different categories have been picked out and analyzed in foster home assessements that have been approved. The conclusion to what is considered to be a suitable foster home is a complex issue, as there are many factors that are interacting. Social workers seem to focus on the importance of a family?s ability to provide some kind of stability and security for a child who is considered to be placed within their home.
