Abstract
Disclosed are systems, methods, and computer-readable storage media for automatic security list offload with exponential timeout. A second layer of a firewall can determine that a first data, that previously passed through a first layer of the firewall, should be blocked. The second layer of the firewall can utilize more resources than the first layer of the firewall to determine whether to block a data packet. In response, a first rule can be applied at the first layer of the firewall to block data packets received from a source of the first data packet. Accordingly, a second data packet received from the source of the first data packet will be blocked at the first layer of the firewall based on the first rule.
