Enterprise Cloud Security and Governance. Efficiently set data protection and privacy principles

Zeal Vora

Modern day businesses and enterprises are moving to the Cloud, to improve efficiency and speed, achieve flexibility and cost effectiveness, and for on-demand Cloud services. However, enterprise Cloud security remains a major concern because migrating to the public Cloud requires transferring some control over organizational assets to the Cloud provider. There are chances these assets can be mismanaged and therefore, as a Cloud security professional, you need to be armed with techniques to help businesses minimize the risks and misuse of business data.The book starts with the basics of Cloud security and offers an understanding of various policies, governance, and compliance challenges in Cloud. This helps you build a strong foundation before you dive deep into understanding what it takes to design a secured network infrastructure and a well-architected application using various security services in the Cloud environment.Automating security tasks, such as Server Hardening with Ansible, and other automation services, such as Monit, will monitor other security daemons and take the necessary action in case these security daemons are stopped maliciously. In short, this book has everything you need to secure your Cloud environment with. It is your ticket to obtain industry-adopted best practices for developing a secure, highly available, and fault-tolerant architecture for organizations.

Etyczne łamanie haseł. John the Ripper, hashcat i inne zaawansowane techniki

James Leyte-Vidal

Umiejętność łamania haseł przydaje się nie tylko przestępcom, ale również specjalistom do spraw bezpieczeństwa. Jest cenna w wielu sytuacjach, na przykład w razie konieczności odzyskania dostępu do systemu po odejściu użytkownika z firmy, w testowaniu penetracyjnym i w obszarze działalności zespołów czerwonych. W takich przypadkach próba złamania hasła ma udowodnić wysoki poziom mechanizmu kontroli dostępu albo jego nieskuteczność. Dzięki tej praktycznej książce dogłębnie zrozumiesz zagadnienia związane z ochroną haseł i odzyskiwaniem chronionych nimi danych. Rozpoczniesz od zapoznania się z zasadami przechowywania danych uwierzytelniających i matematycznymi podstawami technik łamania haseł. Następnie nauczysz się posługiwać różnymi narzędziami ułatwiającymi odzyskiwanie haseł, by potem zająć się typowymi przypadkami ich łamania, odzyskiwania skrótów i pokonywania zabezpieczeń. Przyjrzysz się działaniu metod siłowych i słownikowych, dowiesz się także, jak stosować je przy różnych sposobach przechowywania danych uwierzytelniających. Poszczególne zagadnienia zostały zilustrowane licznymi rzeczywistymi przykładami. Pod koniec lektury przekonasz się, że potrafisz z łatwością łamać najpopularniejsze typy danych uwierzytelniających. W książce między innymi: koncepcje łamania haseł i popularnych typów skrótów identyfikowanie, wyodrębnianie i łamanie skrótów haseł systemów Windows i macOS architektura WPA/WPA2 popularne menedżery haseł, takie jak KeePass, LastPass i 1Password formatowanie skrótów dla portfeli bitcoin, litecoin, Ethereum i ich łamanie Nie ma nic złego w łamaniu haseł, jeśli robisz to etycznie!

Etyczny hacking i testy penetracyjne. Zadbaj o bezpieczeństwo sieci LAN i WLAN

Krzysztof Godzisz

Twoja superbezpieczna sieć lokalna Lokalne sieci komputerowe LAN i bezprzewodowe sieci lokalne WLAN pozwalają łączyć ze sobą urządzenia elektroniczne w ograniczonym obszarze, jakim jest dom, biuro albo budynek. Połączone w ten sposób komputery stacjonarne, laptopy, drukarki, serwery współdzielą zasoby i są podłączone do internetu poprzez router, który zarządza ruchem sieciowym. Ze względu na to, że w ramach takich sieci dostępne są cenne, często wrażliwe dane, zagadnienie ich bezpieczeństwa to kwestia kluczowa zarówno z punktu widzenia administratora, jak i użytkownika. Na szczęście osoby administrujące siecią LAN czy WLAN nie pozostają bezradne wobec prób wyłudzania haseł i danych czy ataków polegających na przeciążeniu serwera. Można je w pewnym sensie uprzedzić i sprawdzić odporność sieci dzięki zastosowaniu metod etycznego hackingu. Ta książka stanowi kompleksowy podręcznik, dzięki któremu nie tylko dowiesz się, jak stworzyć własne laboratorium do testów penetracyjnych, ale też poznasz zagrożenia czyhające na Twoją sieć bezprzewodową i nauczysz się je rozpoznawać, a także im zapobiegać. Opinie o książce: Krzysztof to przede wszystkim pasjonat, który omawiane zagadnienia prezentuje na praktycznych przykładach. Przekazuje wiedzę w sposób przystępny dla początkujących, posługując się przy tym licznymi grafikami pozwalającymi jeszcze lepiej zrozumieć temat cyberbezpieczeństwa. Książka pomoże również uniknąć pewnych problemów z konfigurowaniem środowiska ― żałuję, że nie wyszła, kiedy byłem w technikum. Jeśli szukasz konkretnego poradnika, jak zacząć przygodę z bezpieczeństwem sieci od strony ofensywnej ― ta pozycja na pewno jest warta uwagi! Oskar Klimczuk, dziennikarz i pasjonat cyberbezpieczeństwa w technicznym wydaniu Merytorycznie i fachowo napisana książka. Zawiera opisane krok po kroku szczegóły wraz z licznymi grafikami, by nawet osoba początkująca mogła zgłębić tajniki testowania penetracyjnego i przekonać się, czy to coś dla niej. Karolina Matkowska, HR & Office Director i pasjonatka cyberbezpieczeństwa Jeśli chcesz poznać podstawy łamania zabezpieczeń sieci WLAN i LAN, to polecam zajrzeć do tej książki, przeczytać ją, zakupić adapter i ruszyć do, podkreślmy to, etycznego działania. Krzysztof Godzisz to człowiek o sporej wiedzy i warto się od niego uczyć ― nie tylko teorii i praktyki w zakresie zabezpieczeń sieci, lecz także podejścia do samego procesu łamania zabezpieczeń. W moim przypadku lektura ma jeszcze jeden, niespodziewany efekt uboczny ― poznawszy temat z perspektywy atakującego, przypuszczam, że niejeden jesienny i zimowy wieczór spędzę, zgłębiając temat i nieco reperując zabezpieczenia we własnej sieci. Tak na wszelki wypadek. Lena Sędkiewicz, programistka Połączenie warsztatowego charakteru, świadomej etyki i logicznej struktury. Książka jest naturalnym wyborem dla osób, które chcą naprawdę zrozumieć bezpieczeństwo sieci ― od fundamentów po praktykę. Artur Markiewicz, fascynat cyberbezpieczeństwa

Exploring Experience Design. Fusing business, tech, and design to shape customer engagement

Ezra Schwartz

We live in an experience economy in which interaction with products is valued more than owning them. Products are expected to engage and delight in order to form the emotional bonds that forge long-term customer loyalty:Products need to anticipate our needs and perform tasks for us: refrigerators order food, homes monitor energy, and cars drive autonomously; they track our vitals, sleep, location, finances, interactions, and content use; recognize our biometric signatures, chat with us, understand and motivate us. Beautiful and easy to use, products have to be fully customizable to match our personal preferences.Accomplishing these feats is easier said than done, but a solution has emerged in the form of Experience design (XD), the unifying approach to fusing business, technology and design around a user-centered philosophy.This book explores key dimensions of XD: Close collaboration among interdisciplinary teams, rapid iteration and ongoing user validation. We cover the processes, methodologies, tools, techniques and best-practices practitioners use throughout the entire product development life-cycle, as ideas are transformed to into positive experiences which lead to perpetual customer engagement and brand loyalty.
