Apps Like Advanced Policy Firewall & Comparison with Popular Alternatives For Today

Advanced Policy Firewall Server-based firewall. Created by R-FX Networks Advanced Policy Firewall (APF) is an iptables(netfilter) based firewall system designed around the essential needs of todayโ€™s Linux servers. The configuration is designed to be very informative and easy to follow. The management on a day-to-day basis is conducted from the command line with the โ€˜apfโ€™ command, which includes detailed usage information on all the features.The technical side of APF is such that it utilizes the latest stable features from the iptables (netfilter) project to provide a very robust and powerful firewall. The filtering performed by APF is three fold:1) Static rule based policies (not to be confused with a โ€œstatic firewallโ€)2) Connection based stateful policies3) Sanity based policiesThe first, static rule based policies, is the most traditional method of firewalling. This is when the firewall has an unchanging set of instructions (rules) on how traffic should be handled in certain conditions. An example of a static rule based policy would be when you allow/deny an address access to the server with the trust system or open a new port with conf.apf. So the short of it is rules that infrequently or never change while the firewall is running.The second, connection based stateful policies, is a means to distinguish legitimate packets for different types of connections. Only packets matching a known connection will be allowed by the firewall; others will be rejected. An example of this would be FTP data transfers, in an older era of firewalling you would have to define a complex set of static policies to allow FTA data transfers to flow without a problem. That is not so with stateful policies.
