Palo Alto Firewall – Platforms and Architecture

Control Plane and Dataplane Overview

Debug functions run on either the control plane or the Dataplane

Logging (to the hard drive) is controlled by the control plane

The control plane also referred as Management plane, is where configurations are defined and configured. The control plane considered to be the brain of the firewall and the Dataplane is the muscle of the firewall.

Configuration made within the control plane are pushed by a commit operation to the Dataplane.

The component of the control plane and the Dataplane vary for each platform, series of the firewall.

Different items can leverage the single pass other items can leverage parallel processing

Picture1

  • Signature match is done in parallel.
    The stream passes and is scanned for “signatures”  or patterns.
  • Security Processing requires computation to calculate keys for SSL, IPSEC, opening SSL and setting up sessions.
    This is a simple CPU set of tasks.
    The actual rules are processed here too and the logs are created. So report & Enforce.
    Network processing does networking, like NAT and QoS.
