Systems, methods, and computer-readable storage media are provided for dynamically setting an end point group for an end point. An endpoint can be assigned a default end point group when added to a network. For example, the default end point group can be a baseline port/security group which is considered an untrusted group. The end point can then be dynamically assigned an end point group based on a set of group selection rules. For example, the group selection rules can identify an end point group based on the MAC address or other attributes. When the end point is added to the network, the MAC address and/or other attributes of the end point can be determined and used to assign an end point group. As another example, an end point group can be assigned based on the amount of traffic or guest operation system.
