Informatics, Introduction to IT Security, Second Cycle, 7.5 credits

Learning outcomes

1. Explain the basic concepts related to current computer and network systems with their security vulnerabilities.
2. Describe technical threats that follow from the use of different forms of computing and networking technologies and critically analyze and suggest countermeasures of a particular scenario.
3. Explain how different cryptographic solutions can be used in information systems to provide security and privacy and apply them accordingly.
4. Explain the core principles of system intrusion and analyze system vulnerabilities, using tools as appropriate, for protection.
5. Demonstrate understanding of the principles for secure system development.

Content

The course consists of the following modules:
1: Concepts

• Basic concepts related to computer and network systems including their architectures and their common security vulnerabilities. (Addressing goal 1)

2: Threats and Countermeasures

• Techniques for attacks on different platforms including operating systems, Web and databases and their possible countermeasures that can be applied at different levels uncluding users, system developers and overall system design. (Addressing goal 2)
• Cryptographic techniques including symmetric and asymmetric encryption approaches, digital signatures, and infrastructures for public key certificates and their applications in different scenarios. (Addressing goal 3)
• Techniques on detection of intrusion and protection in computer networks. This includes analysis of attacks such as IP spoofing, packet sniffing, denial of service attacks, and their possible countermeasures. (Addressing goal 4)
• Techniques for secure system development. This includes approaches to system maintainance like software patching, certification of hardware and sofware, backups and mirroring of storage systems, and physical security. (Addressing goal 5)

Examinations and grades

According to the Higher Education Ordinance, Chapter 6, Section 18, a grade is to be awarded on the completion of a course, unless otherwise prescribed by the university. The university may determine which grading system is to be used. The grade must be determined by a teacher specifically nominated by the university (the examiner).

In accordance with university regulations on grading systems for first and second-cycle courses and study programmes (Vice-Chancellor’s decision ORU 2018/00929), one of the following grades is to be used: fail (U), pass (G) or pass with distinction (VG). For courses included in an international master’s programme (60 or 120 credits) or offered to the university’s incoming exchange students, the A to F grading scale is to be used. The vice-chancellor, or a person appointed by them, may decide on exceptions from this provision for a specific course, if there are special grounds for doing so.

The grades used on this course are Fail (F), Sufficient (E), Satisfactory (D), Good (C), Very Good (B) or Excellent (A).

Comments on grades

For an approved final grade on the course, an approved result is required for all examinations. The letter grades A-E are weighted into a final grade based on the examinations of the entire course.

Modes of assessment

For students with a documented disability, the university may approve applications for adapted or other modes of assessment.

For further information, see the university's local examination regulations.

Specific entry requirements

Informatics, Basic Course 30 Credits, 30 Credits at intermediate course level within Informatics and successful completion of at least 15 Credits at advanced course level within Informatics. Alternatively Business Administration, Basic Course, 30 Credits, Business Administration, Intermediate Course, 30 Credits and successful completion of at least 15 Credits at advanced course level within Business Administration. Alternatively 30 Credits within G1N in Computer Science and 45 Credits within G1F in Computer Science. The applicant must also have qualifications corresponding to the course "English 6" or "English B" from the Swedish Upper Secondary School.

For further information, see the university's admission regulations.

Other provisions

The course is offered in English and therefore all examinations will be conducted in English.

Students who have been admitted to and registered on a course have the right to receive tuition and/or supervision for the duration of the time period specified for the particular course to which they were accepted (see, the university's admission regulations (in Swedish)). After that, the right to receive tuition and/or supervision expires.
