TMA-FREEBSD-3.4.1.2
Ensure a single firewall utility is in use
Açıklama
FreeBSD ships with multiple firewall utilities, providing uses with options to best suit their environment. This section provides guidance to ensure that only one firewall utility is implemented. The use of more than one firewall utility may produce unexpected results. Audit: exactly one of firewall_enable (ipfw), ipfilter_enable or pf_enable must be YES.
