Systems Security

Dear students,

please note the following information on the re-exam:

• The Systems Security re-exam will take place on Thursday, 31.03. at 10:45 in HS 1 in E2 5. Please arrive 15 minutes early so we can start on time. Note that we start 15 minutes later than initially planned due to another appointment.

• The seating assignment for the re-exam has been released. You should find your seat on your personal status page. In case you think something is wrong (i.e. you cannot see your seat) please contact us immediately. 

• The exam will take 120 minutes. A non-programmable calculator is allowed, you are not allowed to use a cheat sheet. We will provide a reference with common Intel x86 instructions.

The typical Corona regulations apply for the re-exam:

• A medical mouth-nose-protection mask (surgical mask or FFP2/KN95/N95 mask) must be worn during the entire exam. Please bring such a mask with you, as we are unable to provide them for you.

• Saarland University follows the 3G rule. Thus, to participate in the exam you have to be completely vaccinated, recovered, or have a negative test certificate (a negative antigen rapid test is valid 24 hours, a negative PCR test certificate is valid 48 hours). If you fail to provide proof of your vaccination status, you must leave the campus and your exam is discarded.
  Note: A single dose of “COVID-19 Vaccine Janssen” (Johnson & Johnson) is no longer considered fully vaccinated.

• Students who have the typical symptoms of SARS-Cov2 disease are not be allowed to take exams. This does not include students who have a negative daytime test result. Students who have had close contact with a Corona-positive person may only attend exams and courses if they can show sufficient vaccination protection (basic immunization not longer than 3 months or booster vaccination) or convalescent status (not older than 3 months) or vaccination protection after recovery and are asymptomatic (see § 4 b Ordinance on Corona Pandemic (VO-CP)).

• Students who are unable to take an examination due to isolation or quarantine in accordance with the Ordinance on the Control of the Corona Pandemic (VO-CP) may effectively withdraw from the examinations without receiving a failed attempt. The regulations for withdrawal from examinations of the respective valid examination regulations apply. Proof of the withdrawal must be submitted without culpable hesitation.

We will hold another Q&A tomorrow (Wednesday 16.02) at 13:00 (using the usual Zoom room https://ruhr-uni-bochum.zoom.us/j/66060407187?pwd=a2FzN0N5am5MS1BQOEh2ZkJIcU5lUT09). There will be no active content, we will only answer questions from your side. All documents regarding the exam (e.g., seating plan) are available in CMS.

Unfortunately we need to cancel today's lecture due to a CISPA internal event, we are sorry for the inconvenience! We will link some material in CMS such that you can use the time to learn about other kinds of software vulnerabilities. See you again next week, we will wrap-up the lecture and provide an overview of the exam. About one week before the exam, we will also offer a Q&A session during which you can ask questions.

This year's lecture format will be hybrid, i.e., we will have in-person lectures in the CISPA lecture hall (0.05), which are also streamed through a Zoom webinar. You can find the Zoom link and other information at https://cms.cispa.saarland/syssec/2/Access_to_lectures. The tutorial will be online, we will provide more information in the first lecture.

In-person meetings include mask mandates and students have to register through the Staysio app for each lecture. Should you not wish to use the app, you have to bring in the "alternative sheet" (https://www.uni-saarland.de/fileadmin/upload/page/coronavirus/Alternativformular-Staysio.pdf) to the lectures, which we then have to collect. Beyond that, we recommend usage of the Corona Warn App.
