Deploying Firewalls
Abstract
A firewall is a combination of hardware and software used to implement a security policy governing the network traffic between two or more networks, some of which may be under your administrative control (e.g., your organization's networks) and some of which may be out of your control (e.g., the Internet). A network firewall commonly serves as a primary line of defense against external threats to your organization's computer systems, networks, and critical information. Firewalls can also be used to partition your organization's internal networks, reducing your risk from insider attacks. Firewall technologies have entered into the mainstream. The 1999 Computer Security Institute/FBI Computer Crime and Security Survey indicates that 91 percent of the organizations surveyed already deploy firewalls. Articles and other references covering evaluation, selection, and configuration of firewall technologies are now common in the popular press. However, there has been little published about designing, installing, deploying, operating, and maintaining firewalls. The practices in this module will address designing, installing, and deploying firewalls.
