The DecoySensor records the port openness status based on the SYN-ACK packet returned by the service host and saves the record for 24 hours, until the record ages naturally or updated when a new SYN-ACK packet is generated. During this period, even if the DecoySensor receives the RST-ACK packet from the corresponding port, it does not deceive the traffic.
If the service openness status of the service host is updated, update the record in a timely manner.
