1 Deploying Next Generation Firewall with ASA and Firepower services Dragan Novaković Security Consulting Systems Engineer March 2015.

2 Threat Landscape Demands more than Application Control 60% of data is stolen in hours 54% of breaches remain undiscovered for months 100% of companies connect to domains that host malicious files or services It is a Community that hides in plain sight avoids detection and attacks swiftly Cisco Confidential 2

3 Defense-in-Depth Security Alone Is Not Enough Siloed Approach Poor Visibility Manual and Static Increased complexity and reduced effectiveness Undetected multivector and advanced threats Slow, manual inefficient response Cisco Confidential 3

4 Why?

5 Cisco Confidential 5 5

6 The Configuration Problem Poor awareness of true operational environment Change to environment requiring configuration/posture changes unrecognized Detection content unavailable 0-day No anomaly detection mechanisms in place Cisco Confidential 6 6

7 The Organizational Problem False positive rates too high Operator overload due to mass of equally meaningless events that must be contextualized Frequently technologies are deployed but not properly operationalized Check-box security In 2014, the average cost of an organizational data breach was US$3.5 million Source: The Ponemon Institute Cisco Confidential 7 7

9 What is Sourcefire? From a historical perspective Snort Created Created by Martin Roesch in 1998 Open source network intrusion system Engine Rules Language Sourcefire Founded Founded in 2001 by Martin Roesch Created a commercial version of Snort Sourcefire acquires Immunet Acquisition completed 2011 Advanced Malware Protection ClamAV Cisco acquires Sourcefire Acquisition completed 2013 Cisco Confidential 9

10 What is Sourcefire? From a product perspective Sourcefire IPS/NGFW IPS powered by Snort Includes NGFW features such as URL filtering and Application Visibility and Control Sensors are controlled and monitored by FireSIGHT Defense Center (on premises) AMP for Endpoints Agent installed on each endpoint Endpoints connected to off-premises cloud for has lookups, sandboxing Managed by FIreAMP Console (cloud based) Cisco products Content: ESA, WSA, CWS Network: ASA Cisco Confidential 10

11 Addressing The Configuration Problem Visibility Architecture Collect context about the operational environment Continuously in real-time Visibility data is used to recommend configuration of security infrastructure Real-time notifications of change to drive real-time change in security posture Content Rapid development and dissemination of updated detection is a fundamental Vendor Security operations teams Cisco Confidential 11

12 Addressing The Organizational Problem Contextualization Event loads are high due to misconfiguration Even when well tuned, raw events must be contextualized automatically when possible Operationalization That s your job Engagement from corporate boards is crucial in setting security priorities and expectations Boards need to know what the cybersecurity risks to the business are and their potential impact CIOs must ask tough questions about security controls that are meaningful to the board and outline the business implications Cisco Confidential 12 12

13 Introducing Industry s First Threat-Focused NGFW Proven Cisco ASA firewalling Industry leading NGIPS and AMP Cisco ASA with FirePOWER Services Integrating defense layers helps organizations get the best visibility Enable dynamic controls to automatically adapt #1 Cisco Security announcement of the year! Protect against advanced threats across the entire attack continuum Cisco Confidential 13

19 FireSIGHT Fuels Automation IT Insight Spot rogue hosts, anomalies, policy violations, and more Impact Assessment Threat correlation reduces actionable events by up to 99% Automated Tuning Adjust IPS policies automatically based on network change User Identification Associate users with security and compliance events Cisco Confidential 19 19

20 Impact Assessment Correlates all intrusion events to an impact of the attack against the target Impact Flag Administrator Action Why 1 Act immediately, vulnerable Event corresponds to vulnerability mapped to host 2 Investigate, potentially vulnerable Relevant port open or protocol in use, but no vuln mapped 3 Good to know, currently not vulnerable Relevant port not open or protocol not in use 4 Good to know, unknown target Monitored network, but unknown host 0 Good to know, unknown network Unmonitored network Cisco Confidential 20

22 FireSIGHT : Detecting Anomalies Detects if new application appears or traffic profile changes Identify Hacked Hosts Useful in static environments: Scada, DMZ, MEDTEC... Reduced Risk and Cost ssh ALERT Host has suddenly started to use SSH client and outgoing traffic volume has increased by 3 Cisco Confidential 22

23 FireSIGHT : Automated Responses Use pre-defined or custom script to initiate automatic actions E.g, Quarantine device with ISE API Reduced Risk and Cost change VLAN or SGT I S E Indications Of Compromise - IPS event impact 1 - Malware - Communication with BOTNET QUARANTINE Cisco Confidential 23
