Målsætning : Today any computer professional must have a basic knowledge about network security. This course will present a practical and theoretical survey of the basic concepts, principles and practice of cryptography and network security.
At the end of the course the student will:

Understand the basic concepts, principles and practice of cryptography and network security.
Have the ability to understand professional articles and documentation concerning security issues.
Know where to get more information concerning security issues.
Have the ability to implement security systems.
Have the ability to take security issues into account when developing IT-systems.

Learning objectives:

at the end of the course the student should be able to:

1. explain the various threats, vulnerabilities and attack methods as covered during the course
2. describe the various classes of cryptographic algorithms and explain their relative properties
3. explain the methods for authentication of people, network traffic and systems in the covered protocols and applications
4. explain the application and interplay of the algorithms in the covered network security applications and protocols
5. describe the function and application of network components and applications used for countering threats
6. explain the interplay of network components and security protocols and applications for countering threats and vulnerabilities to security
7. describe the typical content and best practices in a company’s security policy
8. design, realize and document a security solution in a model network
9. apply tools for analyzing and generating network traffic to study security protocols and to test, verify and document the implemented solution.
Grading follows the official statutory order on the 7-point grading scale.:

12 This grade is given for the excellent performance. The student has accomplished the learning objectives with no or only a few unimportant shortcomings
7 This grade is given for the good performance. The student has accomplished the learning objectives but with some shortcomings.
2 This grade is for the acceptable performance where the student have accomplished the learning goals to an just acceptable degree.

The evaluation of the level of accomplishment of the learning goals is based on a professional judgement by the teacher and the ‘external’ examiner.

– Regardless of the accomplishments of learning goal 4-9 the student must have accomplished the goals 1-3 to an acceptable degree in order to pass the course.
