The document describes two methods for domain name resolution in TCP/IP networks:
1) Recursive resolution where a recursive DNS server finds the IP address on behalf of the client.
2) Iterative resolution where the client queries multiple name servers, starting from the root servers, until it reaches the authoritative name server.
QA Fes 2016. Ярослав Пернеровский. Не Jav'ой единой. Пример автоматизации тес...
Традиционно, на проектах где back-end писан на Java, фреймворк тестирования тоже строится на технологиях Java. С одной стороны это оправдано единообразием и уже готовым тулсетом у разработчиков. Но с другой стороны немного усложняет вход в автоматизацию для тестировщиков, не знакомых с тонкостями Java. Новичкам, конечно, можно посоветовать более простые для понимания варианты написания тестов на Ruby или Python, но это уже совсем другой мир, и совсем другой геморрой для DevOps. Очень неплохим вариантом в такой ситуации мне видится использование языка программирования Groovy в паре с тест фреймворком Spock. Эта связка позволяет писать понятные REST API тесты на базе уже существующей Java инфраструктуры.
В докладе на примерах посмотрим как это сделать и попытаемся для себя понять есть ли у такого подхода будущее или это просто баловство для ленивых.

Vincent Ruijter - ~Securing~ Attacking Kubernetes
This talks' focus lays on a popular containerization tool called Kubernetes. Common implementations of Kubernetes are not secure by default and a lot of information about hardening is not known to the public. Since version 1.7 the security level has increased and common security misconfigurations have been mitigated. During this talk it will be demonstrated what happens if these mitigations are not applied and how to abuse them. The talk will be about both securing and attacking the platform and could be considered a 'purple team' talk. Multiple live demos are planned, most of them ending in a guest-to-host escape and a root shell.

Kubernetes: Wie Chefkoch.de mit Containern arbeitet
Container erfreuen sich in letzter Zeit enormer Beliebtheit, da sie Systemadministratoren und Entwicklern eine einfache und gemeinsame Verwaltung Ihrer Infrastruktur ermöglichen. Je nachdem wie die Systemlandschaft aufgebaut ist und wie viel Traffic sie bedienen muss, reicht ein einfaches „docker build + docker run“ aber nicht mehr, um die Container in allen Lebensphasen einer Anwendung verwenden zu können. In diesem Vortrag möchte ich zeigen, weshalb wir uns bei Chefkoch.de deshalb für die Einführung des Orchestrierungs-Tools Kubernetes entschieden haben und wie wir damit Container sowohl in der Entwicklung als auch in allen Testphasen und letztendlich auch in Produktion verwenden.

It covers how services provide stable virtual IPs to access pods, and how kube-proxy implements services by configuring iptables on nodes. It also discusses the DNS integration using SkyDNS and Ingress for layer 7 routing of HTTP traffic. Finally, it briefly mentions network plugins and how Kubernetes is designed to be open and customizable.

Tomada de Decisão em Grupo
This document discusses challenges groups face in decision making and how to overcome them. It notes that groups have the potential to make more informed decisions by drawing on diverse information and perspectives from members. However, this promise is only realized if groups avoid "process loss" by overcoming problems related to composition, participation, and influence. Composition problems include oversampling similar viewpoints. Participation problems involve some members dominating discussion or remaining spectators. Influence problems relate to difficulty voicing disagreement. Process loss is best avoided by legitimizing conflict, soliciting views privately before discussion, and bringing quiet members back into participation.
Web Hacking

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
