Network resources

One of the strengths of GNU/Linux is its network capabilities. These include not only a wide support for protocols and networking hardware, but also a wide variety of servers and clients to communicate via network links. Naturally, a system that provides a large number of network resources also needs to provide appropriate security mechanisms to protect against unauthorized access, data leakage and DOS (Denial Of Service) attacks. In this respect Linux has evolved very far - especially the latest 2.4.X kernels provide a highly configurable kernel with respect to network access control and network logging.
