Ransomware w akcji. Przygotuj swoją firmę na atak cyberprzestępców
Artur Markiewicz
Cyberatak to kwestia czasu. Przygotuj się! Jeśli chodzi o cyberbezpieczeństwo, żadna firma nie jest bezpieczna. Pytanie, które należy sobie zadać, nie brzmi: czy zostaniemy zaatakowani? Odpowiedź na nie jest bowiem oczywista: tak, zostaniecie zaatakowani. Właściwe pytania są takie: Skąd będziemy wiedzieć, że zostaliśmy zaatakowani? Co wówczas zrobimy? Ten poradnik ma za zadanie zawczasu pomóc Ci na nie odpowiedzieć i wesprzeć Cię w momencie, w którym nastąpi atak typu ransomware. Tego typu atak polega na blokowaniu pracownikom dostępu do urządzeń i plików, a następnie żądaniu okupu za jego przywrócenie. Z książki dowiesz się między innymi: Czym jest atak ransomware i jakie są jego możliwe konsekwencje Jakie taktyki stosują przestępcy Jak może wyglądać atak na podstawie studiów przypadków Jak się zabezpieczyć, jeśli chodzi o sprzęt i ludzi W jaki sposób reagować na atak - z podziałem na role: od zarządu po szeregowego pracownika

Ryzyko w cyberbezpieczeństwie. Metody modelowania, pomiaru i szacowania ryzyka. Wydanie II
Douglas W. Hubbard, Richard Seiersen
Lord Kelvin powtarzał, że jeśli nie potrafisz czegoś zmierzyć, to nie znasz tego wystarczająco dobrze. Ta zasada w pełni odnosi się do analizy ryzyka w cyberbezpieczeństwie, a słabość pomiarów prowadzi do podejmowania błędnych decyzji. Ta książka nauczy Cię nowych sposobów myślenia o problemie. Uważam, że jest lekturą obowiązkową dla naszej dziedziny! John "Four" Flynn, CISO Amazon Stores Oto drugie wydanie książki, którą specjaliści CISO uznali za przełomową. Dowiesz się z niej, jak kwantyfikować niepewność i jak za pomocą prostych metod i narzędzi poprawić ocenę ryzyka w nowoczesnych organizacjach. Znalazły się tu nowe techniki modelowania, pomiaru i szacowania, a także mnóstwo praktycznych wskazówek dotyczących wdrażania tych rozwiązań w formie spójnego programu. Nauczysz się też oceniać ryzyko, gdy masz dostęp do niewielu danych. Przekonasz się, że zamiast metod jakościowych dużo lepsze efekty w zarządzaniu ryzykiem cyberbezpieczeństwa osiąga się dzięki kwantyfikacji i zaplanowanym pomiarom. Ta książka umożliwia pewne poruszanie się w złożonym krajobrazie cyberbezpieczeństwa. Jason Chan, były wiceprezes do spraw bezpieczeństwa informacji, Netflix Opisane przez Hubbarda i Seiersena metody są praktyczne. Każdy, kto zajmuje się cyberbezpieczeństwem, powinien je stosować.
