Hey everyone!

Since we want to give you one last in-person opportunity to ask questions about the whole content of this lecture (and because we expect that you are already busy with other exams as well), we decided to skip the last tutorials and instead offer you a grand office hour this Friday, 4 PM, right before the lecture event. There you can ask us any questions about any topic of this lecture.

If you want to participate in-person, you may attend this office hour from 4 PM on (until there are no more questions left and we go to the Ratskeller) in the CISPA lecture hall. Of course, you can also participate in the office hour via Zoom (use Luis' tutorial Zoom link for this).

Note: In case you want to attend on site, please bring a mask as we do not know how many people will come and at CISPA there's still a mandatory rule to wear a mask, if more than 15 people are in the lecture hall at the same time.

Cheers,

Luis.

Sheet 8 - Angr Exercise

Hi all,

 

we observed that some angr versions can not solve exercise 2. More precisely, the sample solution does not work with angr in the pip version 9.1.11611.

Hence, we recommend that you update your angr installations [1] to at least 9.2.6 [2] in case... Read more

Hi all,

 

we observed that some angr versions can not solve exercise 2. More precisely, the sample solution does not work with angr in the pip version 9.1.11611.

Hence, we recommend that you update your angr installations [1] to at least 9.2.6 [2] in case your solution does not work. If you have any further problems, you can reach us through the usual channels.

Cheers,

Daniel

 

[1]: If you haven't had angr installed in the first place, you should be fine.

[2]: You can check your angr version with "pip freeze | grep angr"

The location for today's lecture is E9 1 (CISPA), room 0.05 (lecture hall ground floor). The time stays the same. Of course, there will also be the stream of the lecture.

Hi, 

Due to the "next Campusmesse", the lecture hall is, unfortunately, unavailable tomorrow. Hence, there will only be a stream of the lecture (link as usual in the Materials section). There will also be a Mentimeter link to ask questions during the lecture. 

I hope to still see many of you in the stream.

Hi all,

We observed that some of your solutions contain missing or wrong content in the PDF forms. This can easily happen depending on your PDF viewer.

To double-check you could, e.g., download your submission from the CMS again and check whether the file still contains your answers. It is also often helpful to use the Print-As-File function of your PDF viewer and print the submission again as a PDF.

Cheers,

Daniel

PS: This does not mean that all your submissions must use the PDF forms. Feel free to submit other styles of solutions as long as they are readable.

Hello there,

we, the Capture-the-Flag Team saarsec, consisting of students and lecturers from Saarland University, are giving a workshop to familiarize students with Capture-the-Flag competitions as well as attacking and defending against security vulnerabilities. CTFs are a great way to actually fiddle around with the practical details of mounting attacks and defenses that were theoretically discussed during your studies. This practical experience can not only be beneficial for your studies but also come in handy during later stages of your career. The workshop starts with a short introduction to Linux, followed by different topics such as File Inclusions, SQL Injections, and Command Injections. For each topic, we will discuss how we can find these vulnerabilities, exploit them on a large scale, and how we can fix them. Then, for each each topic, you'll spend more than 50% of the time in each slot on actual challenges. At the end, we will host a CTF for all workshop participants where they can use their newly acquired skills against each other.

FAQ:

Q: When and where?

A: April 10th and 11th, the format (virtual, onsite, or hybrid) will be announced later

Q: Requirements?

A: We do not require any certain skills as we will start with the basics. However, the knowledge from Cysec1 or Security is definitely an advantage.

Q: Sounds awesome! Where can I register or get more information?

A: https://workshop.saarsec.rocks

 

See you there,

Foundations of Cyber Security II

In this lecture, you will learn about software and system security. This includes malware, software vulnerabilities, isolation techniques, and side channels. You will learn about different types of software vulnerabilities, how to find vulnerabilities, how to exploit them, and ways to prevent vulnerabilities as well as techniques to deal with existing vulnerabilities. The following topics are covered in this lecture

  • Malware
  • Operating-system and Low-level Basics
  • Memory Safety + Exploitation
  • Finding Vulnerabilities
  • Preventing Vulnerabilities
  • Dealing with Vulnerabilities
  • Introduction to Side Channels

Time and Location

The lecture will take place every Thursday, 14:00-16:00, starting April, 14th, 2022. Location: E2 2 - Hörsaal 0.01 (Günter-Hotz-Hörsaal). No physical presence is required except for the final exam (see below). A stream of the lecture will be provided via YouTube. The link to the stream can be found in the Materials section before the lecture.

Weekly Tutorials

The weekly tutorials will be in-person, with 1/3 of each tutorial online, which also allows remote participation. We offer 3 tutorial slots

Grading

Only the exam is graded. However, to register for the exam, you need at least 50% of the exercise sheet points. Additionally, there are optional lecture challenges that give you bonus points if you solve them. Bonus points can only be used to get a better grade if you already passed the course.

Written Exam

Exams are done in writing (or orally if the Covid situation does not allow written exams). The final exam will take place on August, 4th, 2022 14:00-16:00 in E2 2 - Hörsaal 0.01 (Günter-Hotz-Hörsaal). Note that physical presence is required for the exam.

All questions of the exam are in English. Answers can be given either in English or in German, at the student’s discretion.

You are allowed to bring a DIN A4 double-sided handwritten paper cheat sheet containing your name and anything you consider useful for the exam. No other materials or tools are allowed during an exam. All materials required to solve the practical questions are provided at the exam.

Lecture Challenges

During the lecture, there will be small “Lecture Challenges” that you can optionally solve as a bonus. These challenges are optional, but solving them results in bonus points. The aim of the challenges is to dig deeper into a certain topic of the respective lecture. Thus, it is advisable to try to complete the challenge soon after the lecture.
