Panorama DGPanorama Device Group
A logical grouping within Panorama that allows administrators to push shared or group-specific policies and objects to a subset of managed firewalls.
Security Policy
A set of rules on a Palo Alto Networks firewall that defines which traffic is allowed or denied based on zones, addresses, applications, users, and services.
Security Profile
A configuration object on a Palo Alto Networks firewall that defines inspection settings for antivirus, anti-spyware, vulnerability protection, URL filtering, file blocking, or WildFire.
Security Profile
A configuration object applied to security policy rules that activates specific threat inspection functions such as antivirus, IPS, or URL filtering.
