Puppet: Mastering Infrastructure Automation

Jaime Soriano Pastor

Puppet is a configuration management tool that allows you to automate all your IT configurations, giving you control. It was written for and by system administrators to manage large numbers of systems efficiently and prevent configuration drifts. Puppet gives you control of what you do to each node, when you do it, and how you do it.This Learning Path will take you from the basics of Puppet to extending it and then mastering it. We will start off with a primer on Puppet, its installation and get a sneak peek under its hood. We will then move on to designing and deploying your Puppet architecture, learning best practices for writing reusable and maintainable code, and executing, testing, and deploying Puppet across your systems. Finally, we will deal with problems of scale and exceptions in your code, automate workflows, and support multiple developers working simultaneously.This course is based on the following books: 1)Puppet 4 Essentials - Second Edition 2)Extending Puppet - Second Edition 3)Mastering Puppet - Second Edition

Python dla DevOps. Naucz się bezlitośnie skutecznej automatyzacji

Noah Gift, Kennedy Behrman, Alfredo Deza, Grig...

Ostatnia dekada zmieniła oblicze IT. Kluczowego znaczenia nabrały big data, a chmura i automatyzacja rozpowszechniły się wszędzie tam, gdzie mowa o efektywności. Inżynierowie muszą wykorzystywać zalety systemów linuksowych w codziennej praktyce, aby zapewnić należyty poziom automatyzacji swoich zadań. Do tych celów świetnie nadaje się Python. Język ten zdobywa coraz większe uznanie z uwagi na jego wszechstronność, jak również wydajność, przenaszalność i bezpieczeństwo kodu. Warto więc wykorzystywać Pythona do administrowania systemami Linux wraz z takimi narzędziami DevOps jak Docker, Kubernetes i Terraform. Dzięki tej książce dowiesz się, jak sobie z tym poradzić. Znalazło się w niej krótkie wprowadzenie do Pythona oraz do automatyzacji przetwarzania tekstu i obsługi systemu plików, a także do pisania własnych narzędzi wiersza poleceń. Zaprezentowano również przydatne narzędzia linuksowe, systemy zarządzania pakietami oraz systemy budowania, monitorowania i automatycznego testowania kodu. Zagadnienia te szczególnie zainteresują specjalistów DevOps. Ponadto zawarto tu podstawowe informacje o chmurze obliczeniowej, usługach IaC i systemach Kubernetes. Omówiono zasady uczenia maszynowego i inżynierii danych z perspektywy DevOps. Przedstawiono także kompletny przewodnik po procesach budowania, wdrażania oraz operacyjnego wykorzystywania modelu uczenia maszynowego z użyciem systemów Flask, sklearn, Docker i Kubernetes. W tej książce: wprowadzenie do Pythona automatyczne przetwarzanie tekstu oraz automatyzacja operacji na plikach automatyzacja za pomocą sprawdzonych narzędzi linuksowych chmura, infrastruktura jako kod, Kubernetes i tryb bezserwerowy uczenie maszynowe i inżynieria danych z perspektywy DevOps tworzenie i operacjonalizacja projektu uczenia maszynowego Python: tutaj ważna jest prawdziwa nowoczesność oprogramowania!

Python Penetration Testing Cookbook. Practical recipes on implementing information gathering, network security, intrusion detection, and post-exploitation

Rejah Rehim

Penetration testing is the use of tools and code to attack a system in order to assess its vulnerabilities to external threats. Python allows pen testers to create their own tools. Since Python is a highly valued pen-testing language, there are many native libraries and Python bindings available specifically for pen-testing tasks.Python Penetration Testing Cookbook begins by teaching you how to extract information from web pages. You will learn how to build an intrusion detection system using network sniffing techniques. Next, you will find out how to scan your networks to ensure performance and quality, and how to carry out wireless pen testing on your network to avoid cyber attacks. After that, we’ll discuss the different kinds of network attack. Next, you’ll get to grips with designing your own torrent detection program. We’ll take you through common vulnerability scenarios and then cover buffer overflow exploitation so you can detect insecure coding. Finally, you’ll master PE code injection methods to safeguard your network.
