Aim
The course wants to give the students a sound knowledge of the security problems that need to be solved in and around the use of computer systems to operate such systems in a networked environment. In such an environment it is important that the correct information is transmitted and is sent to the correct receiver. Encryption, authentication, key management, and digital certificates are examples of notions that will be clarified and exemplified in this course.

Knowledge and understanding
For a passing grade the student must

• Understand and explain the basic security problems that are addressed by data/computer security.

• Understand and explain principles for security solutions for data/computer security.

Skills and abilities
For a passing grade the student must

• Isolate and identify security problems that arise with the use of computers and communication between them.

• Can give different approaches for solving the above mentioned problems.

• Can suggest and explain appropriate measures that are commonly deployed to secure data when being process, stored or communicated.

• Can explain the consequences of practical measures that are employed to secure data and computer systems.
