If attackers discover the presence of the Juniper Networks firewall, they might launch a DoS attack against it instead of the network behind it. A successful DoS attack against a firewall amounts to a successful DoS attack against the protected network in that it thwarts attempts of legitimate traffic to traverse the firewall.
An attacker might use session table floods and SYN-ACK-ACK proxy floods to fill up the session table of JUNOS Software and thereby produce a DoS.
