Firewalls and Tunnels

Part of the book series: Information Security and Cryptography ((ISC))

Abstract

This chapter discusses perimeter-based defenses, starting with firewalls and then complementary enabling technologies for securing network communications of remote users and distance-separated peers. Generic tools called encrypted tunnels and virtual private networks (VPNs) are illustrated by SSH and IPsec. We consider risks of network-accessible services and how to securely provide such services, building familiarity with network defense options (and their limitations). Many examples put security design principles into practice, and give reminders of the primary goals of computer security: protecting data and passwords in transit, protecting resources from unauthorized network access and use, and preserving the integrity and availability of hosts in the face of network-based threats.
