Using the management interface as the HA1 backup link helps avoid split brain in active-passive high availability (HA) pair deployment. High availability (HA) is a feature that provides redundancy and failover protection for firewalls in case of hardware or software failure. Active-passive HA is a mode of HA that consists of two firewalls in a pair, where one firewall is active and handles all traffic, while the other firewall is passive and acts as a backup. Split brain is a condition that occurs when both firewalls in an HA pair assume the active role and start processing traffic independently, resulting in traffic duplication, policy inconsistency, or session disruption. Split brain can be caused by network failures, device failures, or configuration errors that prevent the firewalls from communicating their HA status and synchronizing their configurations and sessions. Using the management interface as the HA1 backup link helps avoid split brain in active-passive HA pair deployment. The HA1 interface is used for exchanging HA state information and configuration synchronization between the firewalls. Using the management interface as the HA1 backup link provides redundancy and failover protection for the HA1 interface, ensuring that the firewalls can maintain their HA communication and avoid split brain. Using a standard traffic interface as the HA2 backup, enabling preemption on both firewalls in the HA pair, or using a standard traffic interface as the HA3 link do not help avoid split brain in active-passive HA pair deployment, but they are related features that can enhance performance and reliability.

Secure Sockets Layer (SSL) Inbound Inspection is the offering that can gain visibility and prevent an attack by a malicious actor attempting to exploit a known web server vulnerability using encrypted communication. SSL Inbound Inspection is a feature that allows the firewall to decrypt and inspect inbound SSL/TLS traffic from external clients to internal servers. SSL Inbound Inspection can gain visibility and prevent an attack by a malicious actor attempting to exploit a known web server vulnerability using encrypted communication by applying threat prevention technologies, such as antivirus, anti-spyware, vulnerability protection, URL filtering, file blocking, data filtering, and WildFire analysis, to the decrypted traffic and blocking any malicious content or activity. OCSP, Advanced URL Filtering (AURLF), and WildFire are not offerings that can gain visibility and prevent an attack by a malicious actor attempting to exploit a known web server vulnerability using encrypted communication, but they are related solutions that can enhance security and visibility.

Kubernetes/Deployment Type/Environment is the structure of the YAML Ain’t Markup Language (YAML) file repository. YAML is a human-readable data serialization language that is commonly used for configuration files. YAML file repository is a collection of YAML files that specify the resources and configuration for deploying and managing infrastructure components, such as firewalls, load balancers, networks, or servers. Kubernetes/Deployment Type/Environment is the structure of the YAML file repository that organizes the YAML files based on the following criteria:

• Kubernetes: The platform that provides orchestration, automation, and management of containerized applications.
• Deployment Type: The method or model of deploying and managing infrastructure components, such as Terraform, Ansible, Helm, or Kubernetes manifests.
• Environment: The type or stage of the cloud or virtualization environment, such as development, testing, staging, or production. Deployment Type/Kubernetes/Environment, Kubernetes/Environment/Deployment Type, and Environment/Kubernetes/Deployment Type are not the structure of the YAML file repository, but they are related ways of organizing YAML files based on different criteria.
