Configuring Access Control Lists (ACLs) on routers is a proactive step to filter out traffic with characteristics that are commonly associated with spoofing activities, such as packets with unexpected source addresses. ACLs establish rules that can allow or block traffic based on IP addresses, protocols, ports, and other header information, enabling the network to reject any packets that fail to meet these established criteria. While changing default passwords strengthens security against unauthorized device access and enabling DHCP snooping protects against malicious DHCP activities, neither is specifically designed to filter traffic patterns or prevent address spoofing. Enforcing role-based access control is more about managing user permissions than monitoring and controlling network traffic.
