Description |
---|
A firewall provides a line of defense against attack. To be effective, it must be enabled and properly configured. Unicast responses to multicast or broadcast messages for a public network will be blocked. This helps minimize the risk of an attacker using broadcast or multicast traffic to deliver malicious payloads. |
