The Juniper SRX Services Gateway must implement service redundancy to protect against or limit the effects of common types of Denial of Service (DoS) attacks on the device itself.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |

| Interfaces can be monitored by a redundancy group for automatic failover to another node. Assign a weight to the interface to be monitored. This configuration is an extremely complex configuration. Consult the vendor documentation. Set the chassis cluster node ID and cluster ID. Configure the chassis cluster management interface. Configure the chassis cluster fabric. Configure the chassis cluster redundancy group Specify the interface to be monitored by a redundancy group. Specify the interface to be monitored by a redundancy group.
