Firewall DoS Attacks Overview

The intent of a denial-of-service (DoS) attack is to overwhelm the targeted victim with a tremendous amount of bogus traffic so that the victim becomes so preoccupied processing the bogus traffic that legitimate traffic cannot be processed.

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.
