Next-generation enterprise security platform

Walter Doria

Why do you need network, endpoint, and cloud

working together?

The network is best for identifying and controlling all traffic,

preventing known threats, and gathering context for analytics

Limitation: the network is not the target…therefore it only sees

data in transit which limits zero-day attack prevention

The endpoint is the best location to prevent zero-day attacks

and gather initial forensics information

Limitations: it’s safer to prevent the attack before it reaches

the target; mobile operating systems limit endpoint capabilities

The cloud is best for gathering information, analyzing,

correlating, and disseminating intelligence back to the

enforcement points

Limitations: the cloud is only as good as the data it receives

and does not actually do prevention on its own

Platform approach

Next-Generation Threat Cloud

Gathers potential threats from network and endpoints

Analyzes and correlates threat intelligence

Disseminates threat intelligence to network and endpoints

Inspects all processes and files

Prevents both known & unknown exploits

Integrates with cloud to prevent known & unknown malware

Next-Generation Endpoint

Next-Generation Firewall

Inspects all traffic

Blocks known threats

Sends unknown to cloud

Extensible to mobile & virtual networks

Next-generation enterprise security platform

① Prevents attacks — even attacks seen

for the first time

② Protects all users and applications —

including mobile and virtualized

③ Seamlessly combines network and

endpoint security, as each has unique

strengths

④ Provides rapid analysis of new threats

Attacks are developed to be hidden

Scaling the threat cloud

On a typical day, WildFire receives over

280,000 unique files

• 11,600 every hour

• 195 every minute

• 3 every second

From those unknowns, about 30,000 are new

malware

• >70% not detected by any of the leading

AV software

On average, each file is processed in less

than 6 minutes

• Even as the number of files has

quadrupled

Summary : Key Benefits of Palo Alto Networks Solution

Our unique approach makes us the only solution that…

Scans ALL applications (including SSL traffic) to secure all avenues in/out

of a network, reduce the attack surface area, and provide context for

forensics

Prevents attacks across ALL attack vectors (exploit, malware, DNS,

command & control, and URL) with content-based signatures

Detects zero day malware & exploits using public/private cloud and

automatically creates signatures for global customer base

Extending Signature Generation Capabilities to WF-500

Generate local malware and command-and-control signatures

directly on the WildFire appliance

Provides 3 types of protection:

• Antivirus signatures – prevent malware downloads

• DNS signatures – block command-and-control traffic

• URL malware categorization – block command-and-

control traffic

Distribute local WF-500 signatures to all PAN-OS firewalls

across the network for consistent network protection

Identify and Protect Against Malicious Email Links

PAN-OS firewalls detect and send web links in

suspicious emails to WildFire

WildFire visits the webpage and analyzes the traffic to

detect exploits and malware

Prevent patient-0 from getting compromised by quickly

adding the URL to PAN-DB

Quickly identify targeted users and machines via email

headers and integration with User-ID

Email Header Information

Configure the User-ID option to enable the firewall to match

User-ID information with email header, information identified in

email links and email attachments that are forwarded to

WildFire.

When a match occurs, the user name in the WildFire log email

header section will contain a link that when clicked, will bring

up the ACC filtered by the User or Group of users.

“Email Session” or “Email Protocol” refers to SMTP and POP3

only.

• If used over SSL decryption will be required

• IMAP is not supported at this time
