Prywatność danych w praktyce. Skuteczna ochrona prywatności i bezpieczeństwa danych
Katharine Jarmul
Chyba nikogo nie trzeba przekonywać, że ochrona danych i zabezpieczenie prywatności są kwestiami absolutnie kluczowymi w cyfrowym świecie. Na szczęście zdajemy sobie coraz lepiej sprawę, że incydenty naruszeń w dziedzinie bezpieczeństwa danych mogą nas narazić na realne szkody. Z drugiej strony niedopełnienie obowiązków wynikających z RODO okazuje się dla organizacji niezwykle kosztowne, a także naraża na szwank ich wizerunek. Zapewnienie należytej ochrony danych to wymagające wyzwanie. Z tego względu inżynieria prywatności z roku na rok staje się coraz ważniejszą dziedziną. Książka w przystępny sposób przedstawia głęboką perspektywę techniczną wraz z przeglądem najnowszych podejść i architektur technologicznych. Emily F. Gorcenski, główna analityczka danych, Thoughtworks Tę książkę docenią osoby, które w ramach codziennej pracy integrują tematy związane z prywatnością i bezpieczeństwem danych. To przewodnik dla pragmatyków, zapewniający gruntowną wiedzę o współczesnych elementach ochrony danych, takich jak prywatność różnicowa, uczenie federacyjne i obliczenia szyfrowane. Znajdziesz tu przydatne wskazówki, jak również najlepsze, wielokrotnie sprawdzone praktyki integracji przełomowych technologii, pozwalające skutecznie i na wysokim poziomie dbać o prywatność i bezpieczeństwo danych. Najważniejsze zagadnienia: Jak przepisy (RODO i CCPA) mają się do przepływów danych i przypadków ich użycia? Jak właściwie anonimizować dane? Czy szyfrowanie homomorficzne jest właściwym rozwiązaniem? Jak wybierać technologie i metody ochrony prywatności? Jak zapewnić bezpieczeństwo danych w projektach opartych na ich analizie? Jak odpowiednio wdrożyć wewnętrzne zasady ochrony prywatności danych? Wreszcie znalazłem książkę, którą mogę polecać wszystkim unikającym tematu prywatności danych!

Przewodnik po MongoDB. Wydajna i skalowalna baza danych. Wydanie III
Shannon Bradshaw, Eoin Brazil, Kristina Chodorow
MongoDB jest wieloplatformowym, nierelacyjnym systemem do obsługi baz danych, napisanym w języku C++. Nie przypomina ściśle ustrukturyzowanych relacyjnych baz danych, zamiast tego korzysta z dokumentów w formacie BSON. Ułatwia to bardziej naturalne przetwarzanie informacji w aplikacjach, oczywiście przy zachowaniu możliwości tworzenia hierarchii oraz indeksowania. W ten sposób cały system zyskuje na wydajności, co jest szczególnie istotne przy przetwarzaniu bardzo dużych zbiorów danych. MongoDB umożliwia stosowanie elastycznych modeli danych, uzyskiwanie wysokiego poziomu dostępności i poziome skalowanie. Ten praktyczny przewodnik jest przeznaczony dla użytkowników bazy MongoDB w wersji 4.2. W przystępny i konkretny sposób opisuje zalety stosowania dokumentowych baz danych, równocześnie wskazuje zaawansowane metody konfiguracji systemu oraz możliwe zastosowania w różnych projektach. Książka zainteresuje zarówno użytkowników i administratorów MongoDB, jak i programistów tworzących złożone aplikacje.
