Operating Systems and Security

Content

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
• Deadlocks
• Security
• Memory
• Quantitative Methods
• Client-Server-Architectures and Process-Communication in Distributed Systems
• Security in Distributed Systems
• File Systems
• Distributed File Systems
• Fault-Tolerance
• Device Drivers

Organisation

Due to the still ongiong Corona-situation in Germany the lecture will take place this semester as an online event. This has the following implications:

Lectures

• Lectures for the part Operating Systems will be published as videos at a weekly basis.
• Lectures for the part Security will take place as an online lecture in BBB. Recordings of this lecture will be published afterwards.

Exercises

• Solutions for the exercises will be published as videos on the website at a weekly basis
• Weekly Question-Answer events on BBB
  • Register for these events on jExam
  • QA-Events will start in the second week of the semester (week starting at the 2nd of November).
  • QA-Events are only meant to answer questions or solve problems that were not covered in the videos.
