You can configure how LAND attacks should be handled. Using SmartDefense Table 37: LAND Fields In this field... Do this... Action Specify what action to take when a LAND attack occurs, by selecting one of the following: • Block. Block the attack. This is the default. • None. No action. Track Specify whether to log LAND attacks, by selecting one of the following: • Log. Log the attack. This is the default. • None. Do not log the attack. Non-TCP Flooding Advanced firewalls maintain state information about connections in a State table. In non-TCP Flooding attacks, the attacker sends high volumes of non-TCP traffic. Since such traffic is connectionless, the related state information cannot be cleared or reset, and the firewall State table is quickly filled up. This prevents the firewall from accepting new connections and results in a Denial of Service (DoS). Chapter 9: Setting Your Security Policy 227
