A system and method for updating network policies may include determining, from a set of hosts, a subset of hosts to have network policies updated; for each host in the subset of hosts, determining a set of policies relevant to the host, and determining a difference between the set of policies relevant to the host and a set of policies relevant to the host determined at an earlier time; and for each of the subset of hosts, installing the set of policies relevant to the host. The difference may be calculated or determined by comparing a file containing the set of policies relevant to the host, and a file containing the set of policies relevant to the host determined at an earlier time, e.g. determined the prior calendar day.

System and method for firewall policy rule management

A system and method may update network policies by determining, among a set of hosts, a subset of hosts to have network policies updated; for each host in the subset of hosts, determining a set of policies relevant to the host; and for each of the subset of hosts, installing the set of policies relevant to the host. The subset of hosts may be determined based on a category or division such as the time zone corresponding to the location of each host in the subset of hosts. The policies relevant to the host may be received from a database and saved to a file with the set of policies relevant to the host; the host may then access the file.
