This document discusses vulnerabilities in the design of the Domain Name System (DNS) and how those vulnerabilities can be exploited. Specifically, it describes how DNS caches, proxies, and routes can be used to map DNS servers and inject content into caches. It also summarizes methods for tunneling arbitrary content through DNS using techniques like modifying Time-To-Live values and encoding data in domain names or record types. Finally, it discusses some approaches for suppressing DNS tunnels, such as flagging unusually large or formatted traffic.
Github Action is the CI/CD tool made by Github. Deeply integrated with Github features, it can not only automate deployments, but also Githu.b repository management. In this sharing I will talk about how we use Github action in LikeCoin and some issues we encountered.
Github is a continuous Integration and Continous delivery platform that provides an excellent option for automating workflows to run specific tasks when some event like code push or a release is triggered on the repository. In this Session we will be exploring Github Actions and learning how to use them in our projects.
Github Actions enables you to create custom software development lifecycle workflows directly in your Github repository. These workflows are made out of different tasks so-called actions that can be run automatically on certain events.
* What is different GitHub Flow and Git Flow?
* What is GitHub Actions?
* How to write the simple workflow?
* What's problem in GitHub Actions UI?
* What's problem with Secrets in GitHub Actions?
* How to write your first GitHub Actions and upload to the marketplace?
* What's a problem with environment variables in GitHub Actions?
Go is a language developed by Google with multi-core in mind. Differ from other languages, concurrency is a first-class primitive in Go. This talk covers some useful patterns for dealing with concurrency.

It is not to complicated to keep new project with good code quality for half year. Maybe, for one year. But what if team works on some project for years? Or even ”better”: you need to support and grow large project after another team. Presentation describes Continuous Inspection, main measures of code quality that will make your life better, continuous inspection and how to cook it with SonarQube.
Palestra apresentada no TDC Recife 2019, na trilha de DevOps.
Apresento uma ferramenta de CI/CD da Microsoft, o Azure Pipelines, serviço que é parte do Azure DevOps, do ponto de vista de um time com quase nenhuma experiência montando um CI/CD. Mostrei algumas funcionalidades que tornaram nossa experiência com a ferramenta mais tranquila e que contribuíram com que a curva de aprendizado fosse a menor possível.
Jenkins is the leading open source continuous integration tool. It builds and tests our software continuously and monitors the execution and status of remote jobs, making it easier for team members and users to regularly obtain the latest stable code.
Slide deck of the presentation done at the Hactoberfest 2020 Singapore event. The talk and demo showed GitHub Actions in practice with examples of Github Superlinter, SonarCloud integration and CI CD to Azure Kubernetes service.

The Domain Name System (DNS) is a critical part of Internet infrastructure and the largest distributed Internet directory service. DNS translates names to IP addresses, a required process for web navigation, email delivery, and other Internet functions. However, the DNS infrastructure is not secure enough unless the security mechanisms such as Transaction Signatures (TSIG) and DNS Security Extensions (DNSSEC) are implemented. To guarantee the availability and the secure Internet services, it is important for networking professionals to understand DNS concepts, DNS Security, configurations, and operations.
This course will discuss the concept of DNS Operations in detail, mechanisms to authenticate the communication between DNS Servers, mechanisms to establish authenticity, and integrity of DNS data and mechanisms to delegate trust to public keys of third parties. Participant will be involved in Lab exercises and do configurations based on number of scenarios.

DNS; The Internet's Directory Service: Services Provided by DNS, Overview of How DNS Works, DNS Records and Messages, Peer-to-Peer Applications: P2P File Distribution, Distributed Hash Tables, Socket Programming: creating Network Applications: Socket Programming with UDP, Socket Programming with TCP.
11 April 2016 - ION Bangladesh - Jan Zorz set up DNSSEC, DANE, and TLS in his go6lab and then tested the implementations in the top one million Alexa domains. Jan will share his experiences deploying, testing, and evaluating DNSSEC, DANE, and TLS in his own lab and explain the process he used.
Decoupling Distributed Systems from IP Networks
Take a trip with Derek Collison into the history of distributed systems, the good and the bad, and now how to move forward.
Is Disk Now a Viable Solution for Archive - Jon Toigospectralogic
Archiving is the most impactful way to alleviate overall storage costs, which today, consume up to 70% of IT hardware budgets. Organizations are pressured to build reliable and auditable archive practices to meet regulatory requirements. Given the growing importance of archives, is tape, disk or some other storage technology the best choice for building an archive?
Please join Jon Toigo, data management veteran, to discuss the latest developments among competing archive platforms and reveal the six key criteria for building enterprise archives.
