Wokół zagadnienia bezpieczeństwa Linuksa narosło sporo mitów. Niektórzy uważają, że jako system open source nie zapewnia odpowiedniego poziomu bezpieczeństwa. Inni - że jedynie eksperci są w stanie poradzić sobie z wirusami i atakami hakerów na ten system. Są również osoby twierdzące, że Linux jest całkowicie odporny na wirusy i trudno go skompromitować. Żadne z tych twierdzeń nie jest do końca prawdziwe. Podczas konfigurowania i użytkowania systemów linuksowych bezpieczeństwo powinno być priorytetem. Istnieje wiele sposobów wykrywania i usuwania luk w zabezpieczeniach i rzetelny administrator systemu jest w stanie poradzić sobie z tym zadaniem. Sięgnij po tę książkę, jeśli jesteś odpowiedzialny za bezpieczeństwo systemu linuksowego. Zawarto tu szereg porad i wskazówek dotyczących konfiguracji jądra, bezpieczeństwa systemu plików i sieci oraz różnych narzędzi usprawniających administrowanie systemem. Nie zabrakło omówienia specjalnych dystrybucji Linuksa, opracowanych z myślą o monitorowaniu bezpieczeństwa. Zaprezentowano zagadnienia dotyczące skanowania w poszukiwaniu luk, wykrywania włamań oraz audytowania systemu Linux. Ciekawym tematem zawartym w książce są zasady bezpiecznego korzystania z takich usług jak HTTPD, FTP i telnet. Zrozumienie zaprezentowanych tu treści jest łatwiejsze dzięki licznym praktycznym przykładom.
