CYBERBEZPIECZEŃSTWO W POLSCE I NA ŚWIECIE Pakiet 2 książki 1) STRATEGIE CYBERBEZPIECZEŃSTWA WSPÓŁCZESNEGO ŚWIATA Opracowanie odnosi się do kwestii cyberbezpieczeństwa w sferze nie tylko krajowej, ale również międzynarodowej, co pozwala na szersze spojrzenie na przedmiotową problematykę. W związku z tym należy je nie tylko ocenić wysoko, ale też szczególnie podkreślić ten fakt. Umiędzynarodowienie cyberbezpieczeństwa pozwala na skuteczniejsze działania w tej sferze, w tym na zapobieganie incydentom mającym niekorzystny wpływ na bezpieczeństwo systemów informacyjnych, a działania takie są ujęte właśnie w strategiach cyberbezpieczeństwa. Prof. Dr hab. Mirosław Karpiuk Zaprezentowane badania cechuje dojrzałość naukowa oraz doskonała znajomość tematyki, która nie ogranicza się jedynie do realiów polskich. Autorki bowiem wnikliwie omawiają i analizują także kształtowanie się systemu cyberbezpieczeństwa w Stanach Zjednoczonych Ameryki, Kanadzie, Francji i Republice Federalnej Niemiec. [...] W recenzowanej monografii można wyróżnić dwie części. Pierwsza jest o charakterze teoretycznym, w której Autorki koncentrują się na aspektach bezpieczeństwa cyberprzestrzeni jako elementu polityki państwa oraz na miejscu cyberbezpieczeństwa w systemie bezpieczeństwa. W drugiej natomiast zostały poddane analizie obowiązujące oraz przyjęte w ubiegłych latach w wybranych państwach strategie i polityki cyberbezpieczeństwa. dr Justyna Kurek 2) SYSTEM BEZPIECZEŃSTWA W CYBERPRZESTRZENI RP Przedstawione dociekania naukowe są trafne i merytoryczne. Wychodzą naprzeciw zapotrzebowaniu państwa i społeczeństwa. (...) jest to dzieło dojrzałe, merytorycznie spójne, ukierunkowane na potrzeby związane z tworzeniem systemu bezpieczeństwa w cyberprzestrzeni RP. płk. dr hab. inż. Piotr Dela, prof. ASzWoj Przedstawione do recenzji opracowanie, o niezwykle nośnym i ambitnym tytule System bezpieczeństwa w cyberprzestrzeni RP, dotykające niezwykle ważnej współcześnie problematyki cyberbezpieczeństwa jest dziełem zbiorowym, gdzie znajduje ujście wiele ciekawych wątków związanych z zakreślonym w tytule obszarem. dr hab.
