Audyt bezpieczeństwa informacji w praktyce
Tomasz Polaczek
Rozpoczęła się era społeczeństwa informacyjnego. Działalność coraz większej liczby organizacji i firm zależy od szybkiego i efektywnego przetwarzania informacji. Informacja stała się cennym, często wykradanym towarem. Zagrożeniem dla bezpieczeństwa danych są nie tylko crackerzy, lecz często także pracownicy firmy, którzy nieświadomie udostępniają zastrzeżone informacje osobom trzecim. Upowszechnienie informacji, będących tajemnicą lub własnością intelektualną i handlową firmy lub instytucji, może oznaczać utratę reputacji, zakończenie działalności na rynku lub nawet wywołać kłopoty natury prawnej. Z tych powodów informację trzeba należycie chronić oraz odpowiednią nią zarządzać. Książka "Audyt bezpieczeństwa informacji w praktyce" przedstawia praktyczne aspekty wdrażania i realizowania polityki ochrony danych. Opisuje zarówno regulacje prawne, jak i normy ISO traktujące o bezpieczeństwie informacji. Zawiera informacje o odpowiednim zarządzaniu systemami przechowywania danych, fizycznym zabezpieczaniu miejsc, w których znajdują się nośniki danych, oraz szkoleniu użytkowników systemów. Normy ISO i PN dotyczące ochrony informacji Planowanie polityki bezpieczeństwa Umowy o zachowaniu poufności Zabezpieczanie budynku i pomieszczeń Tworzenie procedur eksploatacji sprzętu i systemów Ochrona sieci przed programami szpiegującymi Zarządzanie dostępem użytkowników do systemu Odpowiednio zaplanowane procedury ochrony danych mogą uchronić przedsiębiorstwo przed poważnymi problemami.

Cloud security has always been treated as the highest priority by AWS while designing a robust cloud infrastructure. AWS has now extended its support to allow users and security experts to perform penetration tests on its environment. This has not only revealed a number of loopholes and brought vulnerable points in their existing system to the fore, but has also opened up opportunities for organizations to build a secure cloud environment. This book teaches you how to perform penetration tests in a controlled AWS environment.You'll begin by performing security assessments of major AWS resources such as Amazon EC2 instances, Amazon S3, Amazon API Gateway, and AWS Lambda. Throughout the course of this book, you'll also learn about specific tests such as exploiting applications, testing permissions flaws, and discovering weak policies. Moving on, you'll discover how to establish private-cloud access through backdoor Lambda functions. As you advance, you'll explore the no-go areas where users can’t make changes due to vendor restrictions and find out how you can avoid being flagged to AWS in these cases. Finally, this book will take you through tips and tricks for securing your cloud environment in a professional way.By the end of this penetration testing book, you'll have become well-versed in a variety of ethical hacking techniques for securing your AWS environment against modern cyber threats.
