    Rebuilding Landkreis Anhalt-Bitterfeld (rc3-2021)

    Rebuilding Landkreis Anhalt-Bitterfeld (rc3-2021)
    Über den Ransomware-Angriff der zum Ausrufen des Katastrophenfalls führte. Zu den Abläufen im Nachgang, die Rolle und die Aufgaben einer Landkreisverwaltung und was aus dem Vorfall gelernt werden kann. Der Wiederaufbau der IT-Infrastruktur der Landkreisverwaltung Anhalt-Bitterfeld wird sich noch bis weit in das Jahr 2022 ziehen. Was es mit sich bringt, eine Landkreisverwaltung nach einem Ransomware Angriff im laufenden Betrieb neu aufzubauen, welche Priorisierungen vorgenommen werden mussten und welche Auswirkungen es für die Anspruchsgruppen hat, wenn eine öffentliche Verwaltung Offline geht. Und es geht darum, was aus dem Vorfall gelernt werden kann. about this event: https://pretalx.c3voc.de/rc3-2021-chaoszone/talk/Z3PBVS/

    Open Source Procurement and the perfect Hotdog (foss4g2019)

    Open Source Procurement and the perfect Hotdog (foss4g2019)
    We have a well developed and respect for procurement of software and services. How does open source effect what you are shopping for? This talk introduced some of the procurement advantages, trade offs, and options to consider when introducing open source into your organization. A key theme is the additional purchasing power open source offers, additional transparency afforded, along with the responsibility and benefits available through greater control. This talk looks at what makes the perfect hotdog, including several popular options and the authors regional favourite. None about this event: https://talks.2019.foss4g.org/bucharest/talk/GYWHRH/

    How To Kommandozeile (glt18)

    How To Kommandozeile (glt18)
    Wir geben eine Einführung in die Kommandozeile, zeigen grundlegende Befehle anhand praktischer Beispiele. Mit der Kommandozeile kannst du deinen Computer besser kontrollieren, adminstrative Tasks ausführen und automatisieren. Die Kommandozeile ist ein integraler Bestandteil von Linux. Zur Administration eines Systems ist die Kommandozeile unverzichtbar. Dies gilt für Linux am Desktop und noch mehr für Server bei denen oftmals gar keine grafische Oberfläche zur Verfügung steht. Wir werden erklären wie man die Kommandozeile aufruft sowie grundlegende Prinzipien von Linux. Folgende Themengebiete werden vorgestellt: Shell und deren Konfiguration: bash, Umgebungsvariablen, .bashrc, .history Navigation und File Manipulation: ls, cd, cat, mkdir, cp, mv, rm, touch, chmod, chown Kommandos identifizieren: which, type, man, help Installation von Applikationen: apt/apt-get Editieren von Files: nano, vim Prozesse: pkill, killall, xkill, ps, top, htop Sobald du dich eingearbeitet und die Grundlagen verstanden hast, wirst du die Kommandozeile lieber als die grafische Oberfläche verwenden. Gründe die Kommandozeile zu verwenden: Zeitersparnis Abläufe automatisieren (durch Scripting leicht möglich) (Remote-) Serververwaltung, administrative Tasks, mehr Hintergrundwissen erlangen, vielfältige Möglichkeiten zur Konfiguration geeigneteres Werkzeug für manche Aufgaben Diverse Anwendungen können nur über die Kommandozeile aufgerufen werden. about this event: https://c3voc.de

    Race For Root: The Analysis Of The Linux Kernel Race Condition Exploit (SHA2017)

    Race For Root: The Analysis Of The Linux Kernel Race Condition Exploit (SHA2017)
    CVE-2017-2636 is a 7-year old race condition in the Linux kernel that was fixed by Alexander Popov in March, 2017. This vulnerability affected all major Linux distributions. It can be exploited to gain a local privilege escalation. In this presentation Alexander will describe the PoC exploit for CVE-2017-2636. He will explain the effective method of hitting the race condition and show the following exploitation techniques: turning double-free into use-after-free, heap spraying and stabilization, SMEP bypass. #DeviceSecurity about this event: https://c3voc.de

    DocBook Publishing and Authoring Made Easy with DAPS (linuxtag12)

    DocBook Publishing and Authoring Made Easy with DAPS (linuxtag12)
    DocBook is the ideal framework when it comes to publishing large documentation projects in different formats. DocBook provides a "language" (DocBook XML) and a set of stylesheets to translate this language into different output formats such as HTML, PDF, and ePUB. Getting from the XML sources to a usable output such as PDF, requires several steps such as validating, filtering (profiling), converting images and generating an .fo file. DocBook does not provide a tool chain which lets one easily create output formats. Custom solutions (written with make, ant or a scripting language) are necessary for publishing DocBook projects. That is a major hurdle for writers who would like to use DocBook for their documentation projects. The DocBook Authoring and Publishing Suite (DAPS) fills this gap by providing a tool set for easy creation and publication of DocBook sources on Linux. DAPS lets you create HTML, PDF, EPUB, man pages, and other formats with a single command. It automatically takes care of validating and filtering (profiling) your sources and automatically converts images into a format best suited for the output format. Furthermore one can easily create profiled source tarballs for translation or review. DAPS supports authors by providing linkchecker, validator, spellchecker, and editor macros. It is perfectly suited to manage large documentation projects with multiple authors using the DAPS docmanager. DAPS 1.0 is available from http://daps.sourceforge.net/. It currently supports DocBook4; DocBook 5 support is planned for the next major release. DAPS is a Linux-only solution. Über den Autor Frank Sundermeyer: I joined SUSE in 1996 as the webmaster. Until suse.com had been integrated into existing Novell servers I was responsible for the larger part of the SUSE webservers, the content management system, and everything else web related. Besides he did several other jobs at SUSE: product management, marketing, presales, ... . Currently I am a technical writer in the SUSE documentation team. I am also maintaining the documentation team's toolchain (DAPS). about this event: https://c3voc.de
