<p>The goal of this report is to investigate firewalls from both the software and the hardware architecture on their security, functionality, effectives and how the configuration works. The test will consist of scans from Nessus and Nmap which both scans for information and vulnerabilities on the target device. The scans will be performed by first make a basic configuration of the firewall to test its base security. In the second scan will the devices be security configured and rescanned to give an overview on how secure they have become. The target software firewalls used in this test consists of a Debian 4.0, Mikrotik and a Windows 2003 server. The Debian and Windows distributions are both a full OS and have firewall capabilities while Mikrotik is a Linux distribution optimized to work as a firewall. A Cisco 2801 router will also be tested as it is a hardware device optimized for packet handling and have firewall capabilities, and as a router it's likely to already be in a company's network. Finally a Cisco ASA 5510 hardware firewall will be tested to show how a device designed as a firewall will compare to the other devices. The result shows that a Device like the ASA 5510 is clearly superior to any of the other devices in its performance, however the cost efficiency might be in question. The use of a software firewall might be more cost efficient, but might also be more vulnerable as other applications can be run at the OS.</p>

Digitala verktyg är ett begrepp som är vida känt men kan betyda olika saker för olikamänniskor. Läroplanens revidering 2017 gällande digitala verktyg ligger till grund fördetta arbete. Syftet med denna undersökning är att ta reda på hur tillgången på digitalaverktyg ser ut, hur begreppet digitala verktyg kan tolkas och huruvida digitaliseringenimplementerats i undervisningen. Genom denna studie hoppas vi kunna bidra till ökadkunskap och förståelse för digitaliseringens betydelse i skolan och de digitala verktygensanvändningsområden. De metoder som använts är tematisk analysmetod för analys avläroplanens kursplan i ämnet svenska och semistrukturerad intervju som genomförts medsex lärare på sex olika skolor fördelade inom och utanför stadskärnan i samma kommun.Resultaten visar att informanternas tolkning av begreppet digitala verktyg såväl är ienlighet med Skolverkets förklaring till begreppet som att tänka endast hård- ellermjukvaror. Dessutom visar resultaten att informanterna redan innan revideringen avläroplanen till viss del implementerat digitala verktyg i undervisningen, men hur mycketär beroende på hur skolans digitaliseringsplan ser ut. Vidare visar resultaten att tillgångentill de digitala verktygen styr hur mycket och i vilket ändamål som informanternaanvänder dem i undervisningen. Utöver det, visar resultaten på att det inte finns någonskillnad i tillgången till digitala verktyg beroende på om skolorna ligger inom eller utomstadskärnan. / Digital tools are a concept that is widely known but can mean different things to differentpeople. The curriculum's revision in 2017 regarding digital tools forms the basis for thiswork. The purpose of this study is to find out what the availability of digital tools lookslike, how the concept of digital tools can be interpreted and whether digitalisation hasbeen implemented in teaching. Through this study, we hope to contribute to increasedknowledge and understanding of the importance of digitalisation in schools and the usesof digital tools. The methods used are thematic analysis method for analysis of theCurriculum syllabus on the subject of Swedish and semi-structured interview conductedwith six teachers at six different schools distributed within and outside the city centre ofthe same municipality. The results show that the informants' interpretation of the conceptof digital fabric is both in accordance with the Swedish National Agency for Education'sexplanation of the concept and that one thinks of only hardware or software. In addition,the results show that even before the revision of the Curriculum, the informants have tosome extent implemented digital tools in teaching, but how much depends on what theschool's digitalisation plan looks like. Furthermore, the results show that access to thedigital tools controls how much and for what purpose the informants use them in teaching.In addition, the results show that there is no difference in access to digital tools dependingon whether schools are within or outside the city centre.
