Patent ID: 12010095

Abstract:
Some embodiments of the invention provide a novel method for managing layer four (L4) ports associated with a machine executing on a host computer. The method collects a set of contextual attributes relating to applications executing on the machine. It then analyzes the collected contextual attributes to identify at least one L4 port that has to have its status modified. Next, it modifies the status of the identified L4 port. In some embodiments, the status of an L4 port can be either open or closed, and the modification can open a closed port or close an open port. In some embodiments, the method is performed when the machine starts up on the host computer, performed each time a new application is installed on the machine, performed periodically to close unused L4 ports, and/or performed periodically to close L4 ports that should not be open based on a set of L4-port control policies.
