The procedure for thesis defence is set by TTU regulations. The students who have a supervisor from TTU but want to defend their theses in Tartu University in order to fulfil the minimum credit requirements will follow the first two steps (registration and submission of problem statement and submission to the reviewer) as given above. However, OIS declaration, submission of final version and defence should be done according to the deadlines and procedures of Tartu University.
Thesis Defence Overview
Writing and defending an MSc thesis is an important part of the Cyber Security curriculum, as it shows that you can go deep into a specific cyber security research area. This page gives a rough overview of the process, but details should be discussed with your supervisor. This overview part is given according to the assumption that you are following a 4-semester study plan and aim to defend in the May period. If you want to defend in January, then you can adjust the planning phases accordingly.
Generally, the process should start during the first year, by finding a topic-area of interest and by identifying a suitable supervisor. At the end of the second semester, it is highly recommended to have an idea about your topic and have discussed this with your supervisor.
In early December, you should submit a problem statement and research design document (please, find the details, below). Sending this document is considered as a registration to the defence that will take place in next term.
The next step in the process would be conducting the research. As the thesis submission deadline is around the third week of April (for students aiming to defend in January, this deadline is early December), please, plan to finish your work early April, so that your supervisor can review your thesis, give you feedback and you have time to address the feedback before your thesis is being sent to the reviewer/opponent. Jointly with your supervisor, you should then make a decision if your work is ready to be submitted for May defence (or if you need more time and prefer to submit for a January defence). The reviewer will review your thesis and give you feedback. Expect that you should receive the review about a week before the final deadline. You can continue to update your work until the final submission date. You can and should, however, incorporate the review feedback into the final copy of your thesis and defence presentation. This will allow you to make modifications, e.g., fix some typos or clarify some sections, which the reviewer pointed out.
At the final submission deadline, you will have to submit your thesis. On the day of defence, you are expected to give a 15-minute presentation of your work, followed by Q&A from the opponent, committee, supervisor & audience. Make sure you prepare your 15-minute presentation well, this should not be left for the evening before the defence.
Below some more detailed information.
Good luck!
Registration and submission of problem statement and research design document
Each student is required to submit a problem statement and research design document having a length up to 10 pages. The document must include your name, student number, and also the name of thesis and supervisor (and co-supervisor if exists).
About half a year before the defence, the students are required to indicate their intent to defend by this document. See deadlines above set for each semester. Typically this will be around Early December for May defences and Mid June for January defences. You will need to submit this via the TTU Moodle link given in "important deadlines" section of relevant defence period. You'll have to self-enrol yourself in that link. Instructions on how to access the TTU Moodle can be found here. Feedback on the problem statement and research design document should be received within 3-4 weeks via the email account that you defined in TTU Moodle.
The document should include very brief answers to below questions in two or three pages.
• What is the research problem/hypothesis/question?
• What are the goals of the study?
• Why is this study important?
• What are the possible outcomes of the study?
• What are the limitations and key assumptions of the study?
• What is missing in the literature?
• Which methodologies will be used for solving the problem and validation of the study?
This document is evaluated according to the following criteria:
Whether the author
• has a well-defined problem statement,
• successfully presents the significance of the problem,
• knows the literature and the limits of existing solutions,
• have thought about possible methods,
• have thought about how to validate the proposed solution,
• brings a novelty to the literature.
You can find detailed information about research methods here.
Submission to Reviewer
Each thesis will be assigned a reviewer or sometimes called opponent. The reviewer must have at least a Master's degree and relevant knowledge or experience in the field of the thesis topic, and they must not have a conflict of interest (such as being members in the same research group). Students and supervisor may recommend reviewer candidates, but the final assignment will be done by the thesis defence committee.
A reviewer will provide written feedback (typically about two pages) on the thesis. The review should cover the following points:
- short description of the thesis
- strengths and weaknesses of the thesis
- recommended grade (0-5, where 0 is a failing thesis and 5 is an excellent thesis) based on the clarity of the problem and the solution, complexity of the problem, suitability of the chosen solution, proper execution of the solution, and the proper formatting and language use in the thesis.
- at least three questions that can be asked during the defence.
Based on the student's performance at the defence the reviewer may change the recommended grade.
The reviewer will receive a copy of the thesis about two-three weeks before the final/hard university deadline for submitting the thesis. The reason for this is that typically reviewers point out the typos and small factual mistakes that can be fixed in short time (about a week). The student will receive the review one week before the final submission deadline and therefore is able to address some of the comments before submitting the final version. The student can also still decide not to submit the thesis this round, but rather work on improving the quality and then submit an improved version in the next defence period.
OIS declaration
Before a student can proceed to the thesis defence, they have to declare the thesis topic in OIS and get approval from their supervisor. Please pay careful attention to the OIS declaration deadline, as without this you will not be permitted to attend the defence. If you will defend your thesis in Tartu University, then you should do your OIS declaration to their systems according to their deadlines.
Submission of Final Copy
Each student will submit the pdf version of the thesis, the relevant thesis metadata and licence information via moodle course page link given in "important deadlines" section of relevant defence period. Please complete the steps 1, 2 and 3 of the thesis submission on this page.
In addition to submission of above materials via Moodle, one paper copy of your thesis will be collected before defence, which you will get back after defence. The details will be announced one or two weeks before the deadline.
If you will defend your thesis in Tartu University, then you should submit final copy according to the procedures and deadlines of Tartu University.
NB! Do not forget that you need to prepare a 15 min presentation for your defence. This should really not be left to the evening before the defence!
The defence procedure
On the day of defence, students will present their theses according to the announced schedule. Generally, the results will be announced at the end of the day.
The defence procedure for each student consists of the following steps:
- the committee Chairman announces the name of the student, the topic of the thesis, and the names of the supervisor(s) and reviewer.
- the student presents his or her thesis in 15 minutes.
- the student answers the reviewer's questions and the reviewer recommends a grade. This recommendation may differ from the preliminary recommendation, based on how successful the defence was.
- the student answers questions from the committee.
- the student answers questions from the audience.
- the supervisor gives his or her opinion of the thesis and recommends a grade.
NB! The recommended grades by the reviewer and the supervisor are not binding to the committee, who makes the final decision.
- After the thesis defence, please visit the Dean's Office for more information about final formalities.
- Upload your thesis if you would like to have it public
Formal Requirements and recommendations
Until further notice, please use the formatting guide from the School of Information Technologies (link to the guide is given here). Please note that you will have to change the title page as of 01.01.2017:
- write "School of Information Technology" instead of "Faculty of Information Technology"
- write "Department of Software Science" instead of "Department of Computer Engineering".
The thesis code for IVCM is ITC70LT.
The following advices can be considered for a master thesis
- a title page, an author declaration, an annotation in English and Estonian, a list of contents, and references are required in the thesis
- 50-80 pages + appendices if needed
- Times New Roman (or similar), font size 12, 1.5 spacing used for the ordinary text
- Headings are numbered and no more than 3 levels used
- Don't forget page numbers
Topic and supervisor
Every student must have a supervisor when writing the thesis. The supervisor's role is to provide guidance on topic selection and research methods, as well as to give feedback on your work. It is not the supervisor's duty to correct spelling mistakes or formatting errors - they may point such things out, but the responsibility remains with you. Before a thesis will be accepted for defence, the supervisor has to agree that it is of sufficient quality.
Almost any professor and lecturer you have met in your curriculum can act as an supervisor of your thesis. Some of them have some open problems suitable for doing research and writing a thesis, but many may not have a topic to offer right away. It is usually more helpful to have an initial idea of a topic of your thesis and ask someone with interests in the related field to advise you. You can have a supervisor not related to the university, but he can act only as a co-supervisor and you need to agree to somebody related to the curricula or the leading institute of the curriculum to be an official co-supervisor. All (co-)supervisor must have at least a Master's degree.
When refining a topic idea, make sure it has a clear connection with cyber security.

1. A risk-based decision approach for handling digital devices at a crime scene.
It is common for electronic devices such as mobile phones to be discovered at a crime scene, but the means for securing the device is becoming increasingly complex. In spite of this, evidence handling procedures are often static and increasingly out of date, leading to the loss of critical evidence in serious crime.
The phone may be remotely wiped; picking it up may activate motion sensors; and in some cases (such as missing persons) the urgency of the evidence needs to be weighed against securing forensic evidence for investigation and prosecution.
In this research, we consider the development of a risk-based approach to advising crime scene investigators to handle digital devices in the least-worst way.
2. Feasible route mapping
When examining timestamped geolocation data, it is often useful to determine feasible routes which could be taken from one location to another.
Google Maps, for example, provides directions and sometimes provides a small number of alternatives. For criminal investigation, a heatmap of feasible routes would support investigators with a means to rapidly evaluate the context of movement in and around a crime.
In this project, we propose to use the Google Maps Platform (https://developers.google.com/maps/gmp-get-started) to build, through statistical sampling, a heatmap of feasible routes subject to time and modes-of-transportation constraints.
