This diploma thesis describes several selected network attacks detection method using statistical models with NetFlow data. First are described several well known and threats for computer networks, which are easily detectable in the NetFlow data. Thesis also introduce and present the NetFlow technology including its protocol and architecture. The theoretical part of the thesis describes statistical methods with focus on the ASTUTE method, that can be used for an anomaly detection. Following part introduces tools used for method implementation as the NfSen plugins. Last parts of the thesis describe in detail implementation of the plugins and following plugins testing which included simulated network attacks.

The report presents information about the development of an intern logbook made for the company Ångtvättbilen Västernorrland. The application is created with the goal and purpose to make the daily data management more effective and to gather all the coworkers information in one tool. The application is build up with the help of WordPress where the developer creates an own theme together with new post types, plugins and CRUD-functionalities. The project results in an working, responsive, progressive web application where the members can log in to their own personal account. In the app, the coworkers can save data from the work that they are doing or have done. When a member enters information about a work and saves it, the data gets available for all the coworkers to see in an table. The information is from there possible to both edit and delete. The webbapplication also includes a page for image upload where the members can submit images together with an text to the social media manager. The images is delivered by an automatic email. On the webpage there is also a page for a shoppinglist where all the members can add articles that need to be bought. The shoppinglist has all the CRUD-functionalities too. At last every coworker has their own member-profile where they can manage their own information and where they can upload an image of themself. All the personal-information is also visible to the other members on the site. The tools in the application is available from front-end and the coworkers does not have access to the WordPress administration. The goal and purpose of the project is achieved. / Examensrapporten innefattar utvecklingen av en intern företagsapplikation, i form av en loggbok som skapas till Ångtvättbilen Västernorrland. Applikationen skapas med syftet och målet att effektivisera företagets datahantering samt för att ge medarbetarna möjlighet att samla allas information på ett ställe. Applikationen, som blir en progressive web app byggs upp i WordPress genom att utvecklaren skapar ett eget tema samt egna post-typer, plugins och CRUD-funktionaliteter. Arbetet resulterar i en fungerande, responsiv webbapplikation med möjlighet för medarbetarna att, med ett eget konto logga in i applikationen för att därefter ha möjligheten att bland annat lagra data från arbeten som utförs och utförts. När en medarbetare lagrat information om ett arbete visas denna information, tillsammans med författarens namn upp i en tabell synlig för alla medlemmar. Informationen går därefter både att redigera och radera. Webbplatsen innehåller även en undersida för bilduppladdning där medarbetarna kan skicka in bilder tillsammans med bildtext till ansvarig för sociala medier som då får tillgång till datan genom att ett automatiskt mail skickas ut. På webbplatsen finns även en sida som innehåller en inköpslista där alla medarbetare kan fylla på med vad som ska beställas eller köpas in. Inköpslistan har också CRUD-möjligheter så att all data som skapas kan läsas ut, redigeras och raderas. Tillsist har även varje medarbetare en egen profil där de egna uppgifterna kan redigeras samt att alla medlemmar visas upp i en lista tillsammans med dess uppgifter. Alla verktyg på webbplatsen är tillgängliga från front-end och medarbetarna har inte tillgång till baksidan, det vill säga WordPress-gränssnittet.

Inom webbutveckling så är en stor del av webben utvecklad och administrerad med hjälp utav Content Management System (CMS) närmare bestämt hela 43,6% av alla webbsidor hanteras av någon typ av Content Management System. När utveckling av en webbsida är aktuellt, så finns det flera val som behöver göras, ska det genomföras egenutveckling, skall ett ramverk användas eller ska ett CMS användas. I aktuell uppsats står det sist nämnda i fokus och mer specifikt situationer där CMS används och där utvecklare vill lägga till egen funktionalitet till den redan existerande funktionaliteten. Studiens syfte är att jämföra hur det går till att skapa plugin för att utöka funktionalitet i tre olika CMS. Studiens avgränsning är open-source och PHP-baserade CMS och systemen som valts ut är WordPress, Joomla och Drupal. I studien används undersökningsmetoden design science övergripande för att skapa användbara artefakter i form av plugin (tillägg). Datainsamlingsmetoder som används är dagbok, skapad källkod, cyklomatisk komplexitet och dokumentanalys i kombination med IEEE standarder. Med hjälp av en samling kriterier är målet med studien att komma fram till vilket CMS som är att rekommendera vid skapande av plugin. Resultatet av studien visar data om varje kriterium som används för WordPress, Joomla och Drupal. Det CMS som samlade på sig mest poäng var WordPress. WordPress samlade på sig 15 poäng. Medan Joomla samlade på sig 8 poäng och Drupal samlade på sig 11 poäng.Slutsatsen av studien är att WordPress är det CMS som är att föredra vid skapande av eget plugin. Eftersom WordPress samlade på sig mest poäng på fyra av sex kriterier.

This thesis deals with geoinformation analysis of comprehensive landscaping. The thesis compares calculations of the long-term soil loss using different digital terrain models and topographical factors. Subsequently the thesis focuses on the rating of the drain and erosive ratio on the basis of the analysis of the current status of the examined area, that is the circumference of the outcoming comprehensive landscaping in Kunovice cadastral area under the conditions of the conventional agriculture scenario. These resource materials helped the diploma thesis to design anti-erosion measures including the main agricultural roads and the system of ecological stability that was extended with the interactive elements for the needs of these measures. Afterwards their efectivity was succesfully measured. Results of plans are designed in the next part of the thesis to the form of map outputs and in the discussion were debated contributions of the plan from the perspetcive of the opening the water regime of the landscape, the danger of erosion and the ecological stability.

Static analysis is a technique to automatically audit code without having to execute or manually read through it. It is highly effective and can scan large amounts of code or text very quickly. This thesis uses static analysis to find potential threats within a software's extension modules. These extensions are developed by third parties and should not be allowed to access information belonging to other extensions. However, due to the structure of the software there is no easy way to restrict this and still keep the software's functionality intact. The use of a static analysis tool could detect such threats by analyzing the code of an extension before it is published online, and therefore keep all current functionality intact. As the software is based on a lesser known language and there is a specific threat by way of information disclosure, a new static analysis tool has to be developed. To achieve this, a combination of language specific functionality and features available in C++ are combined to create an extendable tool which has the capability to detect cross-extension data access.

LibX is a browser extension that provides direct access to library resources. LibX enables users to add additional features to a webpage, such as placing a tutorial video on a digital library homepage. LibX achieves this ability of enhancing web pages through library applications, called LibApps. A LibApp examines a webpage, extracts and processes information of the page, and modifies the web content. It is possible to build an unlimited number of LibApps and enhance web pages in numerous ways. The developers of LibX team cannot build all possible LibApps by themselves. Hence, we decided to create an environment that allows users to create and share LibApps, thereby creating an eco-system of library applications. We developed the LibApp Builder, a cloud-based end-user programming tool that assists users in creating customized library applications with minimal effort. We designed an easy-to-understand meta-design language model with modularized, reusable components. The LibApp language model is designed to hide the complex programming details from the target audiences who are mostly non-technical users, primarily librarians. The LibApp Builder is a web-based editor that allows users to build and test LibApps in an executable environment. A built-in publishing mechanism allows users to group LibApps into packages and publish them in AtomPub format. Any user can directly reuse or adapt published components as required. Two error checking mechanisms have been built into the LibApp Builder viz., type checking and semantic checking to enhance user experience and reduce debugging effort. Additionally, the web interface displays help tooltips to guide users through the process of building a LibApp. We adhered to good software engineering practices such as the agile development model and the model-view-controller design paradigm. The LibApp Builder is built with the ZK AJAX framework and provides a rich interactive user interface. The LibApp Builder is integrated with an optimized full-text, fuzzy search engine and facilitates faceted search by exploiting the BaseX XML database system and XPath/XQuery processor. Users can locate and reuse existing language components through the search interface. To summarize, the LibApp Builder is a community platform for librarians to create, adapt and share LibApps. / Master of Science

Architectures combining a field programmable gate array (FPGA) and a general-purpose processor on a single chip became increasingly popular in recent years. On the one hand, such hybrid architectures facilitate the use of application specific hardware accelerators that improve the performance of the software on the host processor. On the other hand, it obliges system designers to handle the whole process of hardware/software co-design. The complexity of this process is still one of the main reasons, that hinders the widespread use of hybrid architectures. Thus, an automated process that aids programmers with the hardware/software partitioning and the generation of application specific accelerators is an important issue. The method presented in this thesis neither requires restrictions of the used high-level-language nor special source code annotations. Usually, this is an entry barrier for programmers without deeper understanding of the underlying hardware platform. This thesis introduces a seamless programming flow that allows generating hardware accelerators for unrestricted, legacy C code. The implementation consists of a GCC plugin that automatically identifies application hot-spots and generates hardware accelerators accordingly. Apart from the accelerator implementation in a hardware description language, the compiler plugin provides the generation of a host processor interfaces and, if necessary, a prototypical integration with the host operating system. An evaluation with typical embedded applications shows general benefits of the approach, but also reveals limiting factors that hamper possible performance improvements.
