IT-Forensisk undersökning av flyktigt minne : På Linux och Android enheter / Forensic examination of volatile memory under Linux and AndroidHedlund, Niklas January 2013 (has links)
Att kunna gör en effektiv undersökning av det flyktiga minnet är något som blir viktigare ochviktigare i IT-forensiska utredningar. Dels under Linux och Windows baserade PC installationermen också för mobila enheter i form av Android och enheter baserade andra mobila opperativsy-stem.Android använder sig av en modifierad Linux-kärna var modifikationer är för att anpassa kärnantill de speciella krav som gäller för ett mobilt operativsystem. Dessa modifikationer innefattardels meddelandehantering mellan processer men även ändringar till hur internminnet hanteras ochövervakas.Då dessa två kärnor är så pass nära besläktade kan samma grundläggande principer användas föratt dumpa och undersöka minne. Dumpningen sker via en kärn-modul vilket i den här rapportenutgörs av en programvara vid namn LiME vilken kan hantera bägge kärnorna.Analys av minnet kräver att verktygen som används har en förståelse för minneslayouten i fråga.Beroende på vilken metod verktyget använder så kan det även behövas information om olika sym-boler. Verktyget som används i det här examensarbetet heter Volatility och klarar på papperet avatt extrahera all den information som behövs för att kunna göra en korrekt undersökning.Arbetet avsåg att vidareutveckla existerande metoder för analys av det flyktiga minnet på Linux-baserade maskiner (PC) och inbyggda system(Android). Problem uppstod då undersökning avflyktigt minne på Android och satta mål kunde inte uppnås fullt ut. Det visade sig att minnesanalysriktat emot PC-plattformen är både enklare och smidigare än vad det är mot Android. / The ability to be able to make a efficient investigation of volatile memory is something that getsmore and more important in IT forensic investigations. Partially for Linux and Windows based PCsystems but also for mobile devices in the form of the Android or devices based on other mobileoperative systems.Android uses a modified Linux kernel where the modifications exclusively are to adapt it to thedemands that exists in a operative system targeting mobile devices. These modifications containsmessage passing systems between processes as well as changes to the memory subsystems in theaspect of handling and monitoring.Since these two kernels are so closely related it is possible to use the same basic principles for dum-ping and analysing of the memory. The actual memory dumping is done by a kernel module whichin this report is done by the software called LiME which handles both kernels very well.Tools used to analyse the memory needs to understand the memory layout used on the systemin question, depending on the type of analyse method used it might also need information aboutthe different symbols involved. The tool used in this project is called Volatility which in theory iscapable of extracting all the information needed in order to make a correct investigation.The purpose was to expand on existing methods for analysing volatile memory on Linux-basedsystems, in the form of PC machines as well as embedded systems like Android. Difficulties arisedwhen the analysing of volatile memory for Android could not be completed according to existinggoals. The final result came to show that memory analysis targeting the PC platform is bothsimpler and more straight forward then what it is if Android is involved.

Förgängligt mode eller varaktig konst? : Mode, konst och förgänglighet i kollektionen Haute Papier av Bea SzenfeldGöransson, Amanda January 2014 (has links)
Ephemerality is one of the most essential characteristics of fashion, since fashion by definition is existing in the present, in the fleeing moment. Also, fashion is closely related to art and there is currently no clear theoretical distinction made regarding the boundary between these two domains. In this essay I have explored the concept of transiency and the relationship between fashion and art in relation to fashion in general and to the collection Haute Papier, made by the fashion designer Bea Szenfeld, in specific. The Haute Papier collection is constructed almost entirely out of simple white paper sheets and of this reason it can be regarded as ephemeral. The material also positions the garments in a void between fashion and art, simultaneously existing in both domains and in none of them. I have conducted an object analysis of three of the garments from Haute Papier with the aim of discerning aspects of ephemerality, aspects that criticizes the age in which we live and how the collection positions itself in regard to fashion and art. The theories that I have applied to my material emanates from different aspects of transiency and the fashion and art relationship and includes, among others, theories from Walter Benjamin and Barbara Vinken and extractions from the anthology Fashion and Art by Adam Geczy and Vicki Karaminas. In the analysis it became visible that transiency can be discerned in many varying aspects of the collection, for example in the material and in the time in which fashion operates. What also became visible was that the definition of the object, as art or as fashion, above all depends on which system it is part of, but that it also can change this definition if the context changes.
