Livres Firewalls

In the vast and varied universe of computer books, only a few stand out as the best in their subject areas. Building Internet Firewalls is one of those. It's deep, yet carefully focused, so that almost anything you might want to know about firewall strategies for protecting networks is here. In addition, there's lots of information on the reasons that we build firewalls in the first place, which is to say the security risks that come with Internet connectivity. You'll learn a great deal about Internet services and the protocols that provide them as you follow this book's recommendations for stifling attacks. If there's a shortcoming to this book, it's its lack of coverage of the turnkey firewall products that are becoming popular among home and small-office users. Emphasis here is on more complicated network defenses that require careful design and setup--both design and implementation are the order of the day here. The authors carefully enumerate the threats they see in various situations, go into some detail on how those threats manifest themselves, and explain what configuration changes you can make to your perimeter defenses to repulse those threats. Plenty of illustrations make points about good and bad security strategies (you want to put the routers here and here, not here or here). You'll learn a lot by reading this book from cover to cover, no matter how much experience you have. --David Wall Topics covered: Means of protecting private networks from external security threats. The authors go into detail on attackers' means of exploiting security holes in common Internet services, and show how to plug those holes or at least limit the damage that can be done through them. With coverage of Unix, Linux, and Windows NT, the authors detail their philosophies of firewall design and general security policy.

Sans firewalls, pas de sécurité sur Internet. Ces "pare-feu" ressemblent à des boîtes noires chargées de filtrer le trafic pour éviter les piratages et les sabotages via Internet. L'ouvrage, écrit par deux spécialistes américains des firewalls, propose un état de l'art de ce type de technologie. Bien qu'il soit destiné aux concepteurs de ces produits, il intéressera évidemment les administrateurs système, qui doivent maîtriser TCP/IP, ainsi que les gestionnaires de sites, pour comprendre l'intérêt d'utiliser des firewalls afin de protéger le système d'information de leur entreprise. Chacun trouvera des informations utiles dans les quatre parties de l'ouvrage, de l'intégration des firewalls dans la politique de sécurité aux méthodes d'élaboration et de configuration de ces "pare feu", jusqu'aux moyens pour définir une politique de sécurité cohérente, pour maintenir les firewalls et, surtout, pour réagir aux incidents de sécurité. Cet ouvrage n'est pas avare de conseils pratiques, ce qui le laisse accessible aux non-spécialistes. --François Serge
