DD2395 Computer Security 6.0 credits

Datasäkerhet

Course in computer science that gives an overview of the field of computer security. The course will cover threats as well as counter measures.

The importance and public awareness of computer security is ever increasing. In the past few years, high profile threats such as botnets or ransomware have been making headline news, and security is starting to become a selling point for products.

There are many areas where computer security is a business-critical issue, such as on-line banking, gaming, and web services.

Literature and preparations

Specific prerequisites *

Completed courses in programming equivalent to DD1310/DD1311/DD1312/DD1314/DD1315/DD1316/DD1318/DD1331/DD1337/DD100N/ID1018 and computer science equivalent to DD1338/DD1320/DD1321/DD1325/DD1327/ID1020.

Active participation in a course offering where the final examination is not yet reported in LADOK is considered equivalent to completion of the course. This applies only to students who are first-time registered for the prerequisite course offering or have both that and the applied for course offering in their individual study plan.

Recommended prerequisites

Internet protocols and principles, basics of command-line interface and operating systems, and general programming skills are prerequisites. Web programming (html, javascript, sql) knowledge is needed for lab exercises.

If the course is discontinued, students may request to be examined during the following two academic years.

Grading scale *

A, B, C, D, E, FX, F

Examination *

  • LAB1 - Laboratory Work, 3.0 credits, Grading scale: P, F
  • TEN1 - Examination, 3.0 credits, Grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.
