Ce livre est la transition parfaite entre la saga Harry Potter et la trilogie des Magiciens. [...] En plus de tout ça, on trouve, en vrac : des références culturelles géniales, l'utilisation de la technologie par les sorciers, une guerre inter-espèces, la lutte contre le sexisme, des super-héros discrets, quelques insultes bien envoyées [...] un roman one-shot à lire absolument pour tous ceux qui aiment la magie, les histoires de grands ados (les héros sont majeurs) et, ok, les histoires d'amour un peu.
In the years since the publication of the first edition of this classic reference, Internet use has exploded and e-commerce has become a daily part of business and personal life. As Internet usage has grown, so have the security threats-from password sniffers, to IP forgeries, to defacing web sites, to attacks that shut down popular web sites using distributed denial of service. Firewalls are a very effective way to protect your system from many Internet security threats, and they're a critical component of today's computer networks. Like the first edition of "Building Internet Firewalls", this second edition is a practical and detailed guide to designing and building firewalls and to configuring Internet services to work with firewalls. This much expanded edition covers Linux and Windows NT, as well as Unix. It describes a variety of firewall technologies (packet filtering, proxying, network address translation, virtual private networks) and architectures, and more than one hundred Internet services from email and file transfer, to web services and scripting languages, to naming, authentication, and database protocols. The book also contains chapters on security policies, cryptography, maintaining firewalls, and responding to security incidents, as well as summaries of helpful firewall tools and other resources.
