Go Systems Programming. Master Linux and Unix system level programming with Go

Mihalis Tsoukalos

Go is the new systems programming language for Linux and Unix systems. It is also the language in which some of the most prominent cloud-level systems have been written, such as Docker. Where C programmers used to rule, Go programmers are in demand to write highly optimized systems programming code.Created by some of the original designers of C and Unix, Go expands the systems programmers toolkit and adds a mature, clear programming language. Traditional system applications become easier to write since pointers are not relevant and garbage collection has taken away the most problematic area for low-level systems code: memory management.This book opens up the world of high-performance Unix system applications to the beginning Go programmer. It does not get stuck on single systems or even system types, but tries to expand the original teachings from Unix system level programming to all types of servers, the cloud, and the web.

Gray Hat C#. Język C# w kontroli i łamaniu zabezpieczeń

Brandon Perry

C# to nowoczesny język programowania, który został od podstaw zaprojektowany jako obiektowy. Ta dojrzała technologia jest często wybierana przez twórców oprogramowania, również tego służącego do pokonywania zabezpieczeń systemów. Dzięki temu, że platforma .NET jest oprogramowaniem open source, w C# można pisać kod, który bez problemu będzie działał w każdym systemie operacyjnym. Co prawda język ten jest prosty i łatwy do nauczenia się, jednak dopiero gruntowna znajomość C# umożliwia efektywne tworzenie narzędzi związanych z bezpieczeństwem, służących choćby do wyszukiwania luk w infrastrukturze czy prowadzenia testów penetracyjnych. Ta książka jest przeznaczona dla specjalistów ds. bezpieczeństwa, którzy chcą korzystać z języka C# do takich zadań jak fuzzowanie, skanowanie w poszukiwaniu luk zabezpieczeń i analiza złośliwego oprogramowania. Opisano tu zarówno podstawy języka C#, jak i jego dość zaawansowane funkcje. Przedstawiono szereg bibliotek dostępnych dla tego języka. Pokazano, jak pisać kod wyszukujący luki w zabezpieczeniach i jak tworzyć eksploity. Przedstawiono sposoby korzystania z takich narzędzi jak Nessus, sqlmap i Cuckoo Sandbox. Dzięki technikom zaprezentowanym w książce administrator bezpieczeństwa bez problemu zautomatyzuje nawet najbardziej żmudne codzienne zadania! W tej książce między innymi: Podstawowe i zaawansowane funkcjonalności języka C# Generowanie kodu ładunków, również wieloplatformowych Skanery, w tym OpenVAS, Nessus i Nexpose Automatyczna identyfikacja luk umożliwiających wstrzyknięcie kodu SQL Tworzenie w C# narzędzi do inżynierii wstecznej C#. Sprawdź swój system zabezpieczeń! Brandon Perry jest programistą i gorącym zwolennikiem idei open source. Odkąd pojawiło się środowisko Mono, pisze aplikacje w języku C#. Tworzy też moduły dla frameworka Metasploit, analizuje pliki binarne i zarządza ciekawymi projektami (https://volatileminds.net/). Fascynuje się badaniami nad bezpieczeństwem systemów informatycznych. Chętnie dzieli się swoją wiedzą, pisze książki i pomaga innym w tworzeniu solidniejszego oprogramowania.

Hands-On AWS Penetration Testing with Kali Linux. Set up a virtual lab and pentest major AWS services, including EC2, S3, Lambda, and CloudFormation

Karl Gilbert, Benjamin Caudill

The cloud is taking over the IT industry. Any organization housing a large amount of data or a large infrastructure has started moving cloud-ward — and AWS rules the roost when it comes to cloud service providers, with its closest competitor having less than half of its market share. This highlights the importance of security on the cloud, especially on AWS. While a lot has been said (and written) about how cloud environments can be secured, performing external security assessments in the form of pentests on AWS is still seen as a dark art. This book aims to help pentesters as well as seasoned system administrators with a hands-on approach to pentesting the various cloud services provided by Amazon through AWS using Kali Linux. To make things easier for novice pentesters, the book focuses on building a practice lab and refining penetration testing with Kali Linux on the cloud. This is helpful not only for beginners but also for pentesters who want to set up a pentesting environment in their private cloud, using Kali Linux to perform a white-box assessment of their own cloud resources. Besides this, the book covers a large variety of AWS services that are often overlooked during a pentest — from serverless infrastructure to automated deployment pipelines. By the end of this book, you will be able to identify possible vulnerable areas efficiently and secure your AWS cloud environment.
