Security Zone

A logical grouping of interfaces and subnets that share the same trust level. Zone-based rules decide which traffic is allowed between segments, and a zone must be assigned to each interface before policies apply.

Related: Zone-Based Policy, Interface, Virtual Router
Zone-Based Policy

A firewall rule whose source and destination fields reference security zones rather than individual IP addresses. Traffic is evaluated by the zone pair it traverses, which simplifies rule sets across many subnets.

Related: Security Zone, Security Rule
Security Rule

The core policy object that matches traffic on zone, address, user, application, and service, then applies an action such as allow, deny, or drop. Rules are evaluated top-down within the rulebase.

Related: Zone-Based Policy, App-ID, Rulebase
App-ID

The traffic classification engine that identifies applications by inspecting signatures, protocol behavior, and heuristics, even when they use nonstandard ports or encryption. The identified application then drives policy and security profiles.

Related: Security Rule, Content-ID, User-ID
User-ID

A feature that maps IP addresses to directory users and groups so policies can reference identities instead of addresses. Mapping sources include agents, server monitoring, captive portal, and authentication logs.

Related: App-ID, Security Rule, Captive Portal
Content-ID

The set of scanning engines, including antivirus, anti-spyware, vulnerability protection, and file blocking, that inspects allowed traffic for threats. Content-ID profiles attach to security rules to enforce protection.

Related: Security Profile Group, App-ID, WildFire
Security Profile Group

A container that bundles multiple security profiles, such as antivirus, anti-spyware, URL filtering, and file blocking, so one reference on a rule applies them all. It reduces configuration effort and enforces consistent protection.

Related: Content-ID, URL Filtering Profile, Security Rule
NAT Policy

A rule that rewrites source or destination addresses and ports as traffic crosses the firewall. Source NAT hides internal addresses, while destination NAT publishes internal services to external clients.

Related: Security Rule, Virtual Router, Security Zone
Virtual Router

A logical routing instance that holds interfaces, static routes, and dynamic routing protocols. Multiple virtual routers let one firewall serve separate networks with independent routing tables.

Related: Security Zone, NAT Policy, Interface
Interface

A physical or logical port through which traffic enters or leaves the firewall. Each interface is configured with a mode, such as layer 3, layer 2, virtual wire, or tap, and is bound to a zone.

Related: Security Zone, Virtual Router, Virtual Wire
Virtual Wire

An interface deployment mode that transparently bridges two ports so the firewall sits inline without requiring IP addressing or routing changes. Security policy still applies to the inspected traffic.

Related: Interface, Security Zone
Captive Portal

A web page presented to unauthenticated users before they receive network access. It can collect credentials to build User-ID mappings or display acceptable-use terms for guest networks.

Related: User-ID, Authentication Profile
SSL Forward Proxy

A decryption method where the firewall intercepts outbound TLS sessions, presents its own certificate to the client, and re-encrypts traffic to the server. It enables inspection of encrypted outbound sessions.

Related: SSL Inbound Inspection, Decryption Policy, Content-ID
SSL Inbound Inspection

A decryption method for traffic destined to internal servers, where the firewall uses the server's certificate and private key to decrypt inbound TLS sessions. It requires importing the server key pair.

Related: SSL Forward Proxy, Decryption Policy
Decryption Policy

A rulebase that determines which TLS and SSH sessions are decrypted, bypassed, or blocked. It is evaluated separately from security rules and usually references certificates and URL categories.

Related: SSL Forward Proxy, SSL Inbound Inspection, URL Filtering Profile
URL Filtering Profile

A policy object that categorizes web destinations and allows, alerts, blocks, or continues based on category. It can also enforce safe search and credential-submission controls.

Related: Content-ID, Decryption Policy, Security Profile Group
WildFire

A cloud service that analyzes submitted files and links in a sandbox, then generates signatures that firewalls download to block newly discovered malware. It complements on-box antivirus with unknown-threat detection.

Related: Content-ID, DNS Security, Security Profile Group
DNS Security

A cloud-delivered service that inspects DNS queries and blocks domains associated with malware, phishing, and command-and-control activity. It catches threats before a TCP connection is ever established.

Related: WildFire, Advanced URL Filtering, Security Profile Group
Advanced URL Filtering

A cloud-based web classification service that uses real-time analysis and machine learning to categorize previously unseen URLs and block phishing or malicious pages faster than static databases.

Related: URL Filtering Profile, DNS Security, WildFire
Advanced Threat Prevention

A cloud-delivered engine that detects unknown command-and-control traffic and evasive exploits using inline machine learning and behavioral analysis, complementing signature-based anti-spyware and vulnerability profiles.

Related: Content-ID, WildFire, DNS Security
SaaS Security

A cloud service that discovers and controls sanctioned and unsanctioned SaaS applications, including data sharing and tenant restrictions. It gives visibility into application use that traditional web filtering cannot see.

Related: App-ID, Data Loss Prevention, CASB
CASB

Cloud Access Security Broker: a control point that mediates access between users and cloud services, enforcing policy for shadow IT discovery, data sharing, and tenant restrictions.

Related: SaaS Security, Data Loss Prevention
Data Loss Prevention

A service that inspects content and file transfers for sensitive data patterns, such as credit card numbers or personal identifiers, and blocks or alerts on policy violations. It can apply to web, SaaS, and email traffic.

Related: SaaS Security, Content-ID, Security Profile Group
Enterprise DLP

A centrally managed DLP deployment where policy and incident data are administered from a cloud console and applied across multiple firewalls. It differs from on-box DLP profiles configured per device.

Related: Data Loss Prevention, Strata Cloud Manager
IoT Security

A cloud service that discovers unmanaged devices on the network, profiles their behavior, and recommends policies. It addresses devices that cannot run agents and often lack authentication.

Related: User-ID, Security Zone
Strata Cloud Manager

A cloud-delivered management console for configuring and monitoring firewalls, policies, and security services across an organization. It provides centralized policy, visibility, and health monitoring.

Related: Prisma Access, Configuration Scope, Policy Optimization
Configuration Scope

A folder, snippet, or device grouping in Strata Cloud Manager that determines where configuration objects and rules apply. Scopes are hierarchical, so settings inherit downward and can be overridden locally.

Related: Strata Cloud Manager, Policy Optimization, Security Rule
Policy Optimization

A Strata Cloud Manager capability that analyzes rule usage, identifies redundant or shadowed rules, and suggests consolidation. It helps reduce rulebase complexity and tighten security posture.

High Availability

A deployment where two firewalls pair so one takes over if the other fails. Active-passive and active-active modes synchronize sessions and configuration to minimize disruption.

Related: HA Failover, Session Synchronization, Panorama
HA Failover

The process by which a standby firewall in a high-availability pair becomes active after detecting a failure of its peer. Link, path, and health monitors trigger the transition.

Related: High Availability, Session Synchronization
Session Synchronization

The continuous replication of session state between HA peers so established connections survive a failover. Without it, users would need to re-establish sessions after a switchover.

Related: High Availability, HA Failover
Panorama

A centralized management appliance or virtual machine for configuring and monitoring multiple firewalls. It uses device groups and templates to push policy and network settings consistently.

Related: Strata Cloud Manager, High Availability, Security Rule
Commit

The operation that validates and applies pending configuration changes to the running firewall. Until a commit succeeds, edits exist only as candidate configuration.

Related: Candidate Configuration, Panorama
Candidate Configuration

The editable copy of the firewall configuration where changes are staged before being validated and committed. It allows multiple edits to be reviewed together before taking effect.

Related: Commit, Panorama
Rulebase

The ordered collection of security, NAT, decryption, and other policy rules evaluated for each session. Order matters because the first matching rule typically determines the action.

Related: Security Rule, Policy Optimization, NAT Policy
Authentication Profile

A configuration object that defines how users are authenticated, such as against a local database, RADIUS, LDAP, or SAML identity provider. It is referenced by administrative and end-user authentication features.

Related: User-ID, Captive Portal
Device Group
