A Quantitative Study of Firewall Configuration Errors

Tags: security policy, intranet, firewall

Overview Firewalls are the cornerstone of corporate intranet security. Once a company acquires a firewall, a systems administrator must configure and manage it according to a security policy that meets the company's needs. Configuration is a crucial task, probably the most important factor in the security a firewall provides. Network security experts generally consider corporate firewalls to be poorly configured, as witnessed in professionally oriented mailing lists such as Firewall Wizards. This assessment is indirectly affirmed by the success of recent worms and viruses like Blaster and Sapphire, which a well-configured firewall could easily have blocked. However, no quantified studies directly confirm the extent of the problem because corporate firewall policy configuration files, or rule sets, are highly sensitive and therefore closely guarded.
