Operating Systems and Security


The lecture introduces the fundamentals of systems architecture. Students will learn the key building blocks and construction principles for local systems first and for distributed systems later on. A primary concern for us is to highlight references to neighboring topics. Examples are discussing the interaction of certain hardware characteristics with system building blocks, the introduction to the basics of cryptographic techniques and the application of mathematical methods to ascertain quantitative properties of systems. We also focus on some principles for constructing fault-tolerant and secure systems already in this basic course. A third concern is to get students acquainted with techniques for low-level machine-oriented programming at the latest in this lecture.

Breakdown of the lecture:
  • Introduction
  • Key Building Blocks
  • UNIX
  • Processes and Threads

Exam Preparation (in German only)

The exam takes place each semester and students are encouraged to use the mailing list accompanying the lecture for discussions and questions.

Presumably no exam will be offered in the summer semester 2019.
The numbering at the end of each question designates the year and month of the original use of the question in an exam.
  1. Threads
  2. Memory
  3. Deadlocks
  4. Quantitative Methods
  5. Security
  6. Miscellaneous
  7. Selected Solutions for the marked (*) questions
