Firewalls

Paper Summary:

This paper explains that firewalls have the basic task of controlling traffic between different zones of trusts such as the Internet and an internal network; the goal of a firewall is to control the connectivity between these differing levels of trust zones. The author points out several considerations that need to be considered when choosing a personal firewall for the enterprise environment: (1) Is complete protection offered? (2) Can the firewall protect itself? (3) Does it offer compliance tools to enforce policy compliance? (4) Can it be integrated with all leading gateway vendors and centralized enforcement reporting? The paper reviews three firewall manufacturers who offer software or hardware solutions and their products as applied to specific situations: Symantec, Zone Labs and Cisco Systems.

From the Paper:

"Symantec's Norton Personal Firewall 2005 offers a variety of features. It allows the user to block confidential information, yet still send out personal data to trusted sites. It automatically turns the firewall back on after a pre-determined amount of time, should it need to be turned off temporarily. It automatically blocks suspicious incoming traffic and prevents data being sent without the users' knowledge. The Norton Personal Firewall only allows authorized programs to connect to the Internet. And, LiveUpdate automatically checks for the newest protection updates, when the user is online."
