      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.
