Abstract
A method and system for dynamically modifying rules in a firewall infrastructure. A signed passport, which includes a heart-beat time-out interval and a firewall rule, is received. A trigger signal is generated within the heart-beat time-out interval. The signed passport and the trigger signal are transmitted within the heart-beat time-out interval to a border control agent of a firewall in the firewall infrastructure. In response to receiving, from the border control agent, a continuous confirmation of the firewall rule within a time interval shorter than the heart-beat time-out interval, the firewall is modified according to the firewall rule. In response to determining that the trigger signal was not received by the border control agent within the heart-beat time-out interval, the firewall rule is reset.
