Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng):Software-Defined Networking (SDN) is a new principle in the networking paradigm, which makes a communication network programmable.
With this utility, security properties can be redesigned.
SDN provides new axioms for security applications to implement security services.
In this thesis, security threats troubling Ethernet technology are interpreted and whether the SDN can provide a solution to overcome these is discussed.
Furthermore, existing SDN security applications are presented and compared with author's SDN solution.
The solution is a theoretical design of an SDN implementation that eliminates broadcast messages in a network, which is major Ethernet vulnerability.
Furthermore, development directions are proposed for further investigations for secure SDN development.
Abstract (fin):Software-Defined Networking (SDN) eli ohjelmoitava tietoverkko on uusi periaate tietoverkkotekniikassa, jonka tarkoitus on tehdä tietoverkosta ohjelmoitavan.
Tämän periaatteen avulla, tietoverkon tietoturvaominaisuuksia voidaan toteuttaa uudella tavalla.
SDN tarjoaa uusia ulottuvuuksia tietoturvasovelluksien toteuttamisessa mahdollistaen uusia tietoturvapalveluiden suunnittelua.
Tämän työn tehtävänä on selvittää onko mahdollista ratkaista nykyisen Ethernet tekniikkaa vaivaavat tietoturvauhat SDN periaatteen avulla.
Ethernet tekniikan yleisimmät uhat esitellään työssä yksitellen ja niihin ehdotetaan ratkaisu SDN periaatteen avulla.
Lisäksi työ tulkitsee jo olemassa olevia SDN tietoturvasovelluksia sekä esittelee uuden SDN tietoturvaa kohottavan ratkaisun teoreettisella tasolla.
Tämä ratkaisu on SDN mallinnus järjestelmästä joka eliminoi Ethernet verkossa yleislähetys tiedotteet (broadcast message), joka on yksi merkittävimmistä haavoittuvuuksista Ethernet verkoissa.
Lopuksi työssä ehdotetaan SDN tietoturva ratkaisulle kehityssuuntia jatkotutkimuksia varten.
