When you enable file filtering in Engine, or Layer 2 Interface Policy elements, traffic is checked against the File Filtering Policy.
Note: To enable file filtering in a Layer 2 Interface Policy, you must enable file filtering and select the File Filtering Policy in the Engine Policy.
Steps
-
Select
Engine
Configuration.
-
Right-click a policy and select Edit <policy type>.
-
On the IPv4 Access or IPv6 Access tab, enable file filtering in existing rules or add new rules.
- Enable File Filtering in the action options of individual Access rules.
- Add rules with the Continue action to set defaults for file filtering.
To use file filtering for the IMAPS, HTTPS, or POP3S protocols, you must use a Service element that enables decryption and inspection, and enable TLS decryption on the
Engine.

(Not available in Layer 2 Interface Policies) On the Inspection tab, select the File Filtering Policy.
If there is no custom File Filtering Policy, the default File Filtering Policy is used.
