Using the Heartbeat Backup:

The heartbeat backup is a mechanism that helps to prevent split-brain scenarios in a high availability (HA) configuration by providing an additional path for heartbeat communication. This ensures that both firewalls in the HA pair are aware of each other's status.

Adding a Backup HA1 Interface:

Configuring a backup HA1 interface provides redundancy for the primary HA1 link, ensuring continued communication between HA peers even if the primary link fails. This setup is crucial for maintaining synchronization and preventing split-brain scenarios.

CN-Series for EKS Security:

The CN-Series firewalls are specifically designed to secure Kubernetes environments, such as Amazon EKS. Deploying them in a high availability (HA) pair ensures robust, fault-tolerant security for containerized workloads, providing continuous protection and high availability.

VM-Series firewalls provide advanced application-level security for web-server instances on AWS. These virtual firewalls leverage Palo Alto Networks' next-generation firewall capabilities to offer features like application identification, threat prevention, and URL filtering, ensuring comprehensive security for web applications hosted on AWS.

AWS Security Best Practices: AWS Security Best Practices

To avoid split brain scenarios in an active-passive high availability (HA) pair deployment, the management interface can be used as the HA1 backup link. This ensures reliable communication between the HA pair and prevents both firewalls from assuming the active role simultaneously, which can happen if they lose connectivity with each other on the primary HA1 link.

App-ID is a feature that provides application-based segmentation and helps prevent lateral threat movement within a network. By identifying and controlling applications traversing the network regardless of port, protocol, or encryption (SSL or SSH), App-ID allows granular security policies to be applied, thereby limiting the spread of threats within the network.
