Laboratorium cyberbezpieczeństwa w Dockerze. Zrób to sam

Krzysztof Godzisz

Izolacja procesów i środowisk to dziś jeden z najważniejszych mechanizmów zapewniania bezpieczeństwa systemów IT. Dzięki temu możemy nie tylko bezpiecznie uruchamiać niezaufane zasoby, ale przede wszystkim przeprowadzać testy penetracyjne i badać złośliwe oprogramowanie bez ryzyka, że zainfekuje ono natywne środowisko. Jedną z najwyższych form izolacji jest konteneryzacja - użytkownik ma wówczas praktycznie całkowitą kontrolę na relacją pomiędzy kontenerem a systemem operacyjnym hosta. W ostatnich latach na lidera konteneryzacji wyrosło środowisko uruchomieniowe Docker. Dzięki funkcjonalności, wygodnej obsłudze i szerokiej kompatybilności z różnymi systemami operacyjnymi stanowi on dziś techniczny standard. Docker otwiera przed badaczami cyberbezpieczeństwa nowe możliwości testowania oprogramowania pod kątem bezpieczeństwa i analizy wszelkiej maści malware bez konieczności budowania kosztownej infrastruktury - dzięki Dockerowi i konteneryzacji swoje laboratorium można zbudować w obrębie pojedynczej stacji roboczej. Laboratorium cyberbezpieczeństwa w Dockerze. Zrób to sam to przewodnik instruujący krok po kroku, jak zbudować własne laboratorium w kontenerze Dockera. Szczegółowo omawia proces instalacji środowiska na różnych dystrybucjach Linuksa i jego konfiguracji, a także kwestie związane z zarządzaniem kontenerami i budowaniem zależności.
