Network attacks that deny access to a network device are called DoS
attacks. DoS attacks are aimed at devices and networks with a connection
to the Internet. Their goal is not to steal information, but to disable a
device or network so users no longer have access to network resources.
The Barricade protects against DoS attacks including: Ping of Death (Ping
flood) attack, SYN flood attack, IP fragment attack (Teardrop Attack),
Brute-force attack, Land Attack, IP Spoofing attack, IP with zero length,
TCP null scan (Port Scan Attack), UDP port loopback, Snork Attack.
Note: The firewall does not significantly affect system performance, so
we advise enabling the prevention features to protect your
network.
