Firewall Clustering

A firewall cluster is a setup where multiple firewall devices or instances work together to provide higher availability, scalability, and fault tolerance for network security. In this configuration, the firewalls are typically configured to work in tandem, often through a technique called clustering, to provide load balancing and failover capabilities.

Types of Firewall Clustering:

1. Active-Active Cluster:

2. Active-Passive Cluster:

Key Features of a Firewall Cluster:

High Availability (HA): Ensures that if one firewall device fails, the others in the cluster can take over without downtime.
Load Balancing: Distributes network traffic across multiple firewalls to avoid overloading any single device.
State Synchronization: Firewalls in the cluster synchronize session states, ensuring that session continuity is maintained during failover or load balancing.
