The WildFire Analysis
Environment identifies previously unknown malware and generates
signatures that Palo Alto Networks firewalls can use to then detect
and block the malware. When a Palo Alto Networks firewall detects an
unknown sample (a file or a link included in an email), the firewall
can automatically forward the sample for WildFire analysis. Based
on the properties, behaviors, and activities the sample displays
when analyzed and executed in the WildFire sandbox, WildFire determines
the sample to be benign, grayware, phishing, or malicious. WildFire
then generates signatures to recognize the newly-discovered malware,
and makes the latest signatures globally available every five minutes.
All Palo Alto Networks firewalls can then compare incoming samples
against these signatures to automatically block the malware first
detected by a single firewall. The following workflow describes the
WildFire process lifecycle from when a user downloads a file carrying
an advanced VM-aware payload to the point where WildFire generates
a signature package used by Palo Alto Networks firewalls to protect
against future exposure to malware.
In this example, the following assumptions are made:
A firewall is registered to the
WildFire cloud and is configured to forward supported file types.
The malware found in the file attachment
is an advanced VM-aware threat and has not been encountered before.
The file download is logged if the data filtering logs and
WildFire submissions logs are configured to be forwarded to the

samples you would like to have analyzed to a Palo Alto Networks-hosted
WildFire cloud, a locally-hosted WildFire private cloud, or you
can use a hybrid cloud, where the firewall submits certain samples
to the public cloud and others to a private cloud.
