What is the role of firewalls in protecting against distributed denial-of-service (DDoS) attacks?

The role of firewalls in protecting against distributed denial-of-service (DDoS) attacks is to monitor and filter incoming and outgoing network traffic. Firewalls can detect and block suspicious or malicious traffic patterns associated with DDoS attacks, preventing them from reaching the targeted network or system. They can also help in identifying and blocking IP addresses or sources that are involved in launching DDoS attacks. Additionally, firewalls can provide traffic shaping and rate limiting capabilities to mitigate the impact of DDoS attacks by controlling the flow of network traffic.
