Firewalls Questions
Firewall failover refers to the process of automatically switching to a backup firewall in the event of a failure or downtime of the primary firewall. It ensures high availability of network services by minimizing the impact of firewall failures on the network.
When a primary firewall fails, the failover mechanism detects the failure and triggers the backup firewall to take over its responsibilities. This process is typically achieved through technologies such as Virtual Router Redundancy Protocol (VRRP) or Hot Standby Router Protocol (HSRP).
During failover, the backup firewall assumes the IP address and configuration of the primary firewall, allowing it to seamlessly continue providing network services without interruption. This ensures that network traffic can still flow through the firewall, maintaining the security and accessibility of the network.
By implementing firewall failover, organizations can enhance the reliability and availability of their network services. It helps to prevent single points of failure and ensures continuous protection against potential security threats, even in the event of a primary firewall failure.
