FIREWALL SETTINGS
DoS and Port
Scan
Protection:
A DoS (denial-of-service) attack is characterized by
an explicit attempt by attackers to prevent legitimate
users of a service from using that service.
Examples include: attempts to "flood" a network,
thereby preventing legitimate network traffic,
attempts to disrupt connections between two
machines, thereby preventing access to a service,
attempts to prevent a particular individual from
accessing a service, or, attempts to disrupt service
to a specific system or person.
Port scan protection is designed to block attempts
to discover vulnerable ports or services that might
be exploited in an attack from the WAN.
