En jämförelse av krypteringsalgoritmer

Today the Internet is used more and more as a transportation for information. Much of the information is confidential and should not be read by those not privileged. To protect the information from unauthorized access cryptography can be applied. The cryptography algorithms in use today all have their pros and cons. They are therefore suited for different applications.

ISIT-modellen - Vägledning för att realisera en verksamhets informationssäkerhetsmål

The ISO standard ISO/IEC 17799/SS-627799-2 is a guidance for organizations to realize their information security goals. In spite of this standard, studies show flaws regarding information security in organizations. In particular flaws regarding overall view, knowledge and clear roles and responsibilities have been observed. The ISIT (Information Security Integrated Three level) model and its guidelines, developed in this thesis, help organizations to identify the required processes and procedures as well as the logical process flow. The thesis is based on theoretical studies and a case study within a multinational company.

We have showed that the IT area isn?t just one, it consist of several segments.

Smarta Kort : En del av en intelligent IT-lösning i hälso- och sjukvården?

Background: IT-security is included in the concept of information security, which considers all the security of handling information within an organisation. Good IT-security is about finding the right level of measurement, however, it is hard to implemement new IT-solutions in an organisation, particularly within the health care field, where sensitive information are handled daily.

Carelink, an organisation of interest, is working actively for the presumption of benefit by using IT within the health care field. During spring 2006 the Swedish government introduced a national IT-strategy.

Webbsäkerhet och vanliga brister : kunskapsläget bland utvecklare

This bachelor thesis looks at developers knowledge about web security both regarding their own view on their knowledge and their actual knowledge about vulnerabilities and how you mitigate against them. Web developers knowledge regarding web security are becoming more and more important as more applications and services moves to the web and more and more items become connected to the internet. We are doing this by conducting a survey among developers that are currently studying in the field or are working in the field to get a grip on how the knowledge is regarding the most common security concepts. What we saw was that the result varies between the different concepts and many lack much of the knowledge in web security that is getting increasingly more important to have..

En förändrad värld, en omdanad säkerhet? - En studie om klimatförändringars effekt på svensk säkerhetspolitik

The concept of national security has been a matter for debate during recent years, especially in academic fields. Criticism has surfaced since the end of the cold war, directed towards the traditional perspective's dogmatic focus on armed threats and interstate war. Questions concerning an oncoming paradigm shift have been raised, regarding a widening of the security agenda among national states to also include alternative threats, such as environmental hazards. In this thesis, the focus lies on the effects that climate changes have caused in the Swedish national security agenda during the last 15 years. Swedish policy documents show that there have been some major changes, not only the widening of the security agenda but the entire security domain seems to have changed.

Medicinska elektroniska tidskrifter hur har forskningsbibliotekariens arbetssätt påverkats?

The aim of this study is to describe how Swedish research librarians feel that their work has been affected by electronic journals. The study focuses on medical electronic journals accessed through consortia agreements via Bibsam, the Royal Librarys Department for National Co-ordination and Development. This thesis includes two main parts: a literature survey and an empirical study. The literature survey shows that since the 1990´s most research libraries are hybrid libraries including both printed and electronic information sources and that librarians tasks to seek and organize information have remained but the tools have changed. Qualitative interviews were performed with four librarians at two university libraries and one university college library on how their work with electronic journals differed from their work with printed journals, which new tasks the electronic journals have brought and which have disappeared and how the librarians professional role has been affected.

The main purpose of this Masters thesis was to examine how the Internet and other electronic sources have affected public librarians use of printed reference sources. During the last couple of years the use of the electronic sources - in particular the Internet has become more established in the Swedish public libraries. Our aim was to examine if and how this has affected the use of the printed reference sources. This has been examined on the basis of the following factors: the gender and age of the librarians and how long they have served in the library. We also examined if the size of the library affects the use of the printed and the electronic reference sources and also which factors that are most important when librarians acquire reference sources.

Förstudie till implementering av Electronic Flight Bag

Flygbranschen har på senare år blivit överrumplad av den snabba expansionen av Electronic Flight Bags (EFB) och introduktionen av bärbara läsplattor har öppnat upp för ett mer ekonomiskt alternativ till fast installerad utrustning. Med anledning av detta har NextJet beslutat sig för att genomföra en förstudie för att se om det går att implementera EFB i bolaget på ett säkert och kostnadseffektivt sätt.Den här studien visar att implementering av Electronic Flight Bag inte kunde påvisa några direkta ekonomiska besparingar men uppfattningen är att Electronic Flight Bag ger effektiviseringsförbättringar och kvalitetshöjande bidrag till verksamheten som väger upp kostnaden för investeringen och driften av systemet..

Dataspelsarvet - klassiker och kanonisering

This master thesis deals with computer game classics and a possible computer game canon. It looks closer at four computer game genres - adventure, RPG, action and strategy - in order to discern which games are considered classics and what characterizes them. To answer the first question a quantitative research method was used. 675 computer game reviews from 5 Internetsites were examined in order to see which games are mentioned most often in this context and therefore might be considered classics. To answer the second question a qualitative research method was used.

Vatten som säkerhetsfråga : Med FN:s konstruktion av vattenfrågan som utgångspunkt

ABSTRACTThe aim of this study is to analyse if the UN today constructs the water issue as a security issue and to argue about in which way the organization in that case does so alternatively why it can be said that the UN doesn?t construct the water issue as a security issue.In order to reach this purpose the following questions will be answered:?Does the UN construct the water issue as a security issue today?-If yes, in which way?-If no, why can it be said that the organisation doesn?t?The methods used are qualitative literature studies of policy documents on water from the UN. The focus is to analyze the ideas about water and to apply my theory on the concept of security, which is Barry Buzan?s framework on security, to these ideas.The main results showed that the UN strongly constructs the water issue as an environmental security issue for environments and species and in relatively strong terms also constructs it as an environmental security issue for civilisations. In rare cases the organisation constructs it as a societal security issue, but the UN doesn?t construct the water issue as a military, political or economic security issue..
