Every time you make a Hollywood movie where someone breaks into your computer, hacking scene is really laughable to anyone who knows the first thing about computer security. More importantly, explicit instructions to steal the information is considered safe (Windows NT machines access a file manager, for example) will make you absolutely sure that your computer has a gaping hole in their armor. This book describes the security characteristics of the pillars of the computer industry, including Windows NT, Unix, Novell NetWare, and certain firewalls. The authors walk readers through a variety of attacks, explaining what the attacker wants, how they defeat the security features that are relevant, and what they do once they have reached their destination. If you're running Linux, you may want to complete the Unix information in this book with Maximum Linux Security, other minded and very popular text-practical security. There is information about the survey remote system, identify weak spots and exploiting weaknesses in certain operating systems (Windows NT, Unix, and Novell NetWare, mostly).
