Grundkurs IT-Sicherheit in bewegten Bildern

Sobald es um IT-Sicherheit bzw. genauer gesagt, den Schutz der Privatsphäre bei der Nutzung von Informations- und Kommunikationstechnologie geht, hat der Laie kaum eine Chance den Rat der Experten zu folgen. Die zu Grunde liegende Technik ist an sich schon recht komplex. Bei der Aufklärung bedienen sich Experten am liebsten Ihrem Fachjargon, während den unbedarften Nutzern beim Zuhören nur die Ohren flattern. Sobald diese dann noch jäh aus Ihrer heilen Welt gerissen werden, durch Whistleblower die von einer omnipräsenten Überwachung durch repressive Regime, Geheimdienste und andere kriminelle Organisationen berichten … mag man am Ende nur hoffen, dass alles nicht so schlimm ist und man selbst ja eh nichts zu verbergen hat … und man macht weiter wie bisher.

Zum Glück gibt es Alexander Lehmann, von dem in diesem Blog schon mehrere Beiträge gezeigt wurden. Mit seinem Projekt „Verschlüsselung Einfach Erklärt“ verbildlicht er in fünf animierten Kurzfilmen wichtige Grundsätze des sicheren Umgangs mit IT. Kurz, verständlich und äußerst empfehlenswert.

Die Kurzfilme sind von Ende 2015 bis Mitte 2016 veröffentlich worden, illustriert von Lena Schall und mit der Stimme von Florian Maerlender. Gefördert wurden sie u.a. von der Heinrich Böll Stiftung, Rosa Luxemburg Stiftung und FIfF e.V.

Aber genug des Schreibens … nun zu den Bildern.

HowTo: Installing Yosemite into VirtualBox

This post should give a quick overview and some background on how to install Mac OS X 10.10 Yosemite in VirtualBox version 4.3.22.

VirtualBox is great because it is probably the only free and open source software based virtualization environment that supports most common platforms (like GNU/Linux, Windows, and Macintosh) and where the virtual machines are portable in case you want to switch the host’s operating system.

One more thing …

This is normally the phrase when every serious fanboy gets very excited at Apple’s Keynote. What Jonathan Zdziarski – a forensic scientist – recently summarised in his talk „Identifying Back Doors, Attack Points, and Surveillance Mechanisms in iOS Devices“ at the Hope X conference is the other one more thing that any Apple addict should be (made) aware of and that probably might cause a quite different sense of excitement. In short his summary reads like this:

Böses WhatsApp

Ein Sturm der Empörung läuft gerade über sämtliche Gruppenchats bei WhatsApp. Egal ob Freunde, Kollegen oder Freizeitclub:

„… ab morgen bin ich raus, ich schmeiß dieses böse WhatsApp runter und bin nur noch über [dazu kommen wir noch] erreichbar!“

Aber was ist passiert? Facebook hat WhatsApp und seine 450 Millionen Nutzer für 19 Milliarden Dollar gekauft. Nun kommt die große Angst, dass Facebook eifrig Werbung schaltet und fleißig mitschneidet inkl. Direktzugriff für die NSA.

Use of Open Source Software in Health Care Delivery – Results of a Qualitative Field Study

The article about my previous research has finally been published in the IMIA Yearbook 2013. It is meant to provide a practitioner’s perspective on the use of medical free/libre and open source software (FLOSS) in clinical routine. In this context I examined and presented the opinions and experiences of chief information officers (CIO) working at larger hospitals. The abstract reads like this:

Objectives: To assess and analyze the attitude of health IT executives towards the utilization of specialized medical Open Source software (OSS) in Germany’s and other European countries’ health care delivery.

Methods: After an initial literature review a field study was carried out based on semi-structured expert interviews. Eight German and 11 other European health IT executives were surveyed. The results were qualitatively analyzed using the grounded theory approach. Identified concepts were reviewed using SWOT analysis.

Results: In total, 13 strengths, 11 weaknesses, 3 opportunities, and 8 threats of the utilization of OSS in a clinical setting could be identified. Additionally, closely related aspects like general software procurement criteria, the overall attitude of health IT executives, users, and management towards OSS and its current and future use could as well be assessed.

Conclusions: Medical OSS is rarely used in health care delivery. In order to capitalize the unique advantages of OSS in a clinical setting, complex requirements need to be addressed. Short-comings of OSS describe an attractive breeding ground for new commercial offerings and services that need yet to be seen.

Towards Open Collaborative Health Informatics – The Role of Free/Libre Open Source Principles

A general overview article about free/libre and open source software in the context of health care to which I strongly contributed as co-author has recently been published in the IMIA Yearbook 2011. The abstract reads like this:

Objectives: To analyze the contribution of Free/Libre Open Source Software in health care (FLOSS-HC) and to give perspectives for future developments.

Methods: The paper summarizes FLOSS-related trends in health care as anticipated by members of the IMIA Open Source Working Group. Data were obtained through literature review and personal experience and observations of the authors in the last two decades. A status quo is given by a frequency analysis of the database of, one of the world’s largest platforms dedicated to FLOSS-HC. The authors discuss current problems in the field of health care and finally give a prospective roadmap, a projection of the potential influences of FLOSS in health care.

Results: FLOSS-HC already exists for more than 2 decades. Several projects have shown that FLOSS may produce highly competitive alternatives to proprietary solutions that are at least equivalent in usability and have a better total cost of ownership ratio. The database currently lists 221 projects of diverse application types.

Conclusions: FLOSS principles hold a great potential for addressing several of the most critical problems in health care IT. The authors argue that an ecosystem perspective is relevant and that FLOSS principles are best suited to create health IT systems that are able to evolve over time as medical knowledge, technologies, insights, workflows etc. continuously change. All these factors that inherently influence the development of health IT systems are changing at an ever growing pace. Traditional models of software engineering are not able to follow these changes and provide up-to-date systems for an acceptable cost/value ratio. To allow FLOSS to positively influence Health IT in the future a „FLOSS-friendly“ environment has to be provided. Policy makers should resolve uncertainties in the legal framework that disfavor FLOSS. Certification procedures should be specified in a way that they do not raise additional barriers for FLOSS.
