[HIForum] Computer-Museum im Advent

Liebe HIForum-Mitglieder,

es gibt eine tolle Chance, in Ruhe das Museum zu besuchen, hier ist die Einladung an den Fachbereich, die ich gerne an unsere Vereinsmitglieder weitergeben möchte:

ich habe eine Lücke im Kolloquiumsplan entdeckt und möchte sie mit einem Angebot schließen:

Advent im Computer-Museum
Montag, 3. Dezember
14:00 - 18:30 Uhr Open Museum mit Heißgetränken (Glühwein, …) in Haus C, Keller C-015
16:00 - 17:30 Uhr Führung (max. 12 Personen, Anmeldung per E-Mail an oberquelle@informatik.uni-hamburg.de), 
Treffpunkt Eingang Haus B (Konrad-Zuse-Hörsaal)

Dies ist für 2018 die letzte allgemeine Chance, das hoch interessante Computer-Museum mit seinen Hunderten von Exponaten live kennen zu lernen.
Interessenten für eine Führung zu einer anderen Zeit sollten eine Gruppe sammeln und mich kontaktieren.

Mit besten Grüßen
Horst Oberquelle

Abstract

One of the Internet's greatest strengths is the degree to which it facilitates access to any of its resources from users anywhere in the world. The Internet has already become a crucial part of our life. People around the world use the internet to communicate, connect, and do business. Yet various commercial, technical, and national interests constrain universal access to information on the internet.

 

I will discuss three reasons for the closed web that are not caused by government censorship: blocking visitors from the EU to avoid GDPR compliance, blocking based upon the visitor's country, and blocking due to security concerns. These decisions can have an adverse effect on the people of the blocked regions, especially for the developing regions. With many key services, such as education, commerce, and news, offered by a small number of web-based Western companies who might not view the developing world as worth the risk, these indiscriminate blanket blocking could slow the growth of blocked developing regions.

 

As we are building the future web, we need to discuss the implication of such blocking practices and build technologies that ensure an open web for users around the world.

Abstract

From cloud servers to IoT devices, modern CPUs provide a complex microarchitecture to ensure high performance while easing parallelization. Unrelated services often run in parallel on the same platform and share resources. At the logic level, sandboxing ensures isolation between services. However, isolation is not perfect, and side channels caused by the CPU's shared microarchitecture can result in unintended information leakage across processes and virtual machines. For instance, cache attacks that exploit access time variations when retrieving data from the cache or the memory are a powerful tool to extract information from a co-located process. - This talk provides an overview of how microarchitectural features of modern CPUs such as shared caches and speculative execution can be abused to circumvent isolation techniques. It will be shown how the resulting attacks can be applied to extract sensitive information from privileged processes and even across processor boundaries. Modern attack techniques such as cache attacks as well as the infamous Spectre and Meltdown attacks will be presented and discussed.
