Each rule matches source zone, source address, destination zone, destination address, application, service/port, user, and optionally HIP and URL category, then applies an action (allow, deny, drop, reset) plus logging and a security profile group. Rules are evaluated top-down, first match wins ; ordering is the biggest single source of errors.
318 words, about 2 min04Control Access to Applications
App-ID classifies traffic by signature, protocol and behaviour rather than by port, so you can allow a sanctioned SaaS app while blocking an anonymiser on the same port 443. Applications are referenced individually, through application filters (dynamic, attribute-based such as category, subcategory, technology, risk) or application groups (static lists).
327 words, about 2 min05Control Access to URLs
URL filtering resolves each session to a PAN-DB category and applies a URL Filtering profile attached to an allow rule, directly or through a profile group. Each category maps to an action: allow , block (with a block page), continue (a warning page the user can click through), override (requires a password to proceed), or none .
