Common Firewall Configuration Errors
------------------------------------------------------------------------
SUMMARY
The protection that firewalls provide is only as good as the policy they
are configured to implement. Analysis of real configuration data shows
that corporate firewalls are often enforcing rule sets that violate well
established security guidelines.
DETAILS
Excerpt:
Firewalls are the cornerstone of corporate intranet security. Once a
company acquires a firewall, a system administrator must configure and
manage it according to a security polivy that meets the company's needs.
Configuration is a crucial task, probably the most important factor in the
security firewall provides.
In this article, Avishai Wool focus on rule sets for
<http://www.checkpoint.com> Check Point's FireWall-1 product and,
specifically, on 12 possible misconfigurations that would allow access
beyond a typical corporation's network security policy. By documenting the
frequency of misconfigurations in actual firewall data, Avishai Wool was
able to check whether the configuration quality is correlated with other
factors specifically, the operating on which the firewall runs, the
firewall's software version, and a new measure of rule-set complexity.
