Agenda

• What are we talking about?

• Modern warfare

• Firewall evolution

• Threat landscape

• Security Intelligence

• Summary

Network-Centric Warfare

• 1996, Admiral William Owens described the evolution of a system of intelligence sensors, command and control systems, and precision weapons that enabled enhanced situational awareness, rapid target assessment, and distributed weapon assignment.

• An information superiority-enabled concept of operations that generates increased combat power by networking sensors, decision makers and shooters to achieve shared awareness, increased speed of command, higher tempo of operations, greater lethality, increased survivability and a degree of self-synchronization.

• Power To The Edge’s

• State of security – Past and Present• What is a firewall?• How have firewalls been evolving?

• Is a firewall still necessary?

• High-end customer requirements• Performance• Segmentation• Compliance mandates• Do more with less

Firewall Technology Overview

What is (was) a firewall?

• Software / Hardware barrier between intranet (LAN) and extranet (WAN)

• Permit or deny traffic based on policies / rules• Source IP address/port, destination IP address/port, destination service,

protocols, source domain, etc.

• Stateful – maintains information about existing sessions• Make decisions based on session state rather than individual packets

• Perimeter Gateway – common entry point to LAN

How have they evolved?

• From Packet Filter to Stateful to NextGen• Addressing the evolving threat landscape

• FW/IPsec VPN – secure remote tunnels into corporate• UTM – AV, antispam, URL filtering, DI/IPS, and more

• Consolidate security posture into a single appliance• Application / NextGen Gateways

• From Perimeter to Infrastructure / Core• Addressing the needs of changing network function / design

• Multiple entry points to network• Partner portals, remote connectivity, wireless, etc

• Segmentation capabilities – network zoning• Enforcement of user roles / responsibilities

Is firewall still needed?

• Still 1st line of defense• DoS/DDoS protection• Ports / protocols usage

• White lists, black lists – allow or deny

• NATing – transition between IPv4 and IPv6

• Regulatory Compliance• Requires security in depth including firewall

• PCI, SCADA, and others

• Segmentation of LAN• Separate zones / policies to logically separate traffic• Enforce corporate policies

Firewalls – reality ;-)

•Separation of tasks•Expensive, high-touch

•No logical integration•Very complex set-up & ongoing maintenance

•Uncompromised performance•Complete inheritance•Best in class services

Stand-aloneSpecialized functions

•Stateful FW•IPSec VPN•IDP•Routing

Bolt-onLoose functional integration & coordination

•FW “houses” add-on svcs•Single chassis convenience

Fully-integratedHW/SW optimized for full integration – Tight coordination with apps & functions

Firewall

Evolution of Integration

• Removable top barrel hurls 20mm high-explosive air-bursting fragmentation rounds more than a half-mile. The lower barrel shoots NATO-standard 5.56mm ammunition. These rounds provide accurate single-round or bursts to about 500 yards. Laser-guided electronics as sophisticated as on a modern tank.

Next-Generation Firewall (NGFW)

• Application Visibility and Control

• User-based Controls

• Intrusion Prevention Services

Emphasis on Visibility

Evolution Of The Firewall

Open platform delivers more value

Scalable to ensure full enterprise or service provider deployment

Built for expansive data capacity

Improved efficacy, with fine-tuning

Adaptive in its ability to incorporate many types of data into policy

The Current Security Threat Landscape

• Attacks coming faster; attackers getting smarter• Complex attacks using multiple vulnerabilities• No simple solution works

– Patching helps– Firewalls help– AV & attachment removal help– Encrypted passwords/tunnels help

• You can’t be “secure”; only “more secure”• We must share information better

Juniper “Feed” Creation & Structure

• Consolidate data• Weed out false positives• Add/normalize scores• Prioritize based on current

threat landscape

The Juniper Threat Feed

• Juniper threat feeds are designed to maximize enforcement point resources

• Policy can be fine-tuned using threat scores

Not all threat intelligence is created equal

The Optimization Process

Threat intelligence iscollected from a

variety of sources

Sourcing Threat Data

• Juniper is committed to delivering focused threat intelligence (C&C, botnet)

• We utilize a variety of threat data sources and techniques to ensure intelligence is current and actionable

• All data sources are carefully evaluated by Juniper’s threat research team

Rinse & Repeat

Optimize

Generate Feed

Source Data

• Threats change often• Refresh all data sources at

regular intervals• Spotlight Secure ensures that

data delivered to customer premise is fresh and actionable

Support for Custom Feeds

• Security intelligence solution supports customer choice• Multi vendor data can easily be integrated into the solution• Scalable component within SD aggregates all data for customer• Management still occurs through same SD-based tools• Support for blacklist and whitelist – Customer defines policy that uses data

• Update Mechanisms• File PUSH through Security Director• Web server PULL• Local appliance/service PUSH interface

Dynamic Address Groups• Dynamic Address Groups can be used as either “Source Address” or

“Destination Address” in a firewall rule.

• A Dynamic Address Group is updated dynamically and does not require any configuration commit.

• The following type of feeds are supported in the first version:• Custom IP-list feeds• GeoIP feed (from Spotlight Cloud)

Summary

• Status• Competitive intelligence is a work-in-progress• More details will be made available as we near formal launch (we are almost

ready)

• Highlights• Centralized and open threat intelligence framework• Highly scalable and performant firewall implementation• Emphasis on efficacy, particularly with integration of attacker fingerprinting

Big Data Platforms and Security Intelligence

Customers looking to combine Big Data Platforms and Security

Intelligence to derive further security insights including:

• Beaconing

• Identify a pattern of connectivity from internal hosts or

users to external endpoints over a long period of time.

• Advanced base lining

• Model normal behavior of users, apps, assets and other

organizational entities so that anomalous behavior can be

identified

• Users susceptible to spear phishing

• Enumerate users who are prone to spear phishing attacks

because of their propensity to click suspicious URL links

and who may require additional security training
