An application-aware firewall in Cisco SD-WAN provides advanced security by allowing policies to be defined based on specific applications and their behaviors.
* Sequence: In the context of an application-aware firewall, a sequence defines the order in which firewall rules are evaluated. Each sequence can contain match conditions and corresponding actions to be taken if the conditions are met.
* Default Action: The default action is a crucial component that specifies what action to take if none of the defined sequences match the traffic. This ensures that there is always a fallback action to handle unmatched traffic, providing a safety net for security policies.
