Enterprise Threat Management (ETM): Bringing Security Together Through Intelligence David Thomason Director of Security Engineering
2 X X X X X X X X X Insider Accidental Attacks In an FBI Computer Crime Survey released on 1/11/07, 44% of participants said they were attacked from within their own organizations. Outsider Attacks According to the 2006 Ponemon Data Breach Study, those surveyed who experienced data theft in the last year spent an average of $660,000 to notify customers, business partners, and regulators. Compliance Enforcement According to John Hagerty of AMR Research, “…it [automated compliance] also comes down to an issue of visibility. Where do I have problems? Where do I have exposure? That’s when it starts to become a more strategic issue because management is asking for an overall view of this.” Insider Malicious Attacks In a survey jointly done by ASIS International and the U.S. Chamber of Commerce, 138 executives of Fortune 1000 companies reported losses between $53 billion and $59 billion due to insider attacks. Undetected Attacks According to ComputerWorld Magazine, the TJX security breach, that was reported in mid-December of 2006 and could put the credit and debit card data of more than 40 million customers at risk, was not detected for seven months. Look Familiar? The Agony of Today’s Network Security Unknown Connections The most recent CSI/FBI Crime Computer and Security Survey reports that 66% of the security incidents that caused the greatest organizational losses were unauthorized access and theft of proprietary information.
3 Current Security Spending Trends: Unsustainable Growth Security spending is dramatically growing as a percentage of the overall IT budget… Source: 2006 CIO/CSO/PWC State of Info Security Survey Yet the threats and vulnerabilities keep coming! In fact, it is growing twice as fast as overall IT spending (12% vs. 6%)…
4 What’s Going on Here? The awareness of the problem is there Billions of dollars have been spent on IT security The security problem is getting worse as attackers become more motivated. Today’s professional hacker does not want his work to be noticed. The TJX security breach (T.J. Maxx stores) – disclosed in 12/06 – was one of the largest in retail history and went undetected for seven months! How is it possible for so many security technologies to be defeated? The silo approach of “see a threat, buy a box” is no longer feasible.
5 Key Flaws in Current Network Security Network security technology operates with virtually no knowledge about what it’s protecting Virtually all network security technology is driven solely by people These factors combine to lead to network defenses that are misconfigured, porous, and static “By the end of 2007, 75% of enterprises will be infected with undetected, financially motivated, targeted malware that evaded their traditional perimeter and host defenses. The threat environment is changing — financially motivated, targeted attacks are increasing, and automated malware-generation kits allow simple creation of thousands of variants quickly — but our security processes and technologies haven't kept up.” Gartner's Top Predictions for IT Organizations and users, 2007 and Beyond
6 Security Events Must Have Context Is this guy a threat? Or a valued customer? Is he holding a gun? Or an iPod? Is it summer in Sydney? Or winter in New York? Do you reach to set off the alarm? Or to shake his hand? Unfortunately, the majority of network solutions today lack the ability to integrate intelligence into the real-time analysis of potential threats.
8 Worms Trojans Port scans Buffer overflow attacks Spyware Protocol anomalies Malformed traffic Invalid headers Zero-day attacks Protection Against The Role of Intrusion Prevention Vulnerability-based Intrusion Prevention First line of ETM defense IPS rules should address the “vulnerability”—not the “exploit” Protection against zero-day attacks IPS events should be correlated against endpoint intelligence IPS is just one part of an effective ETM strategy
9 The Role of Vulnerability Assessment “Active” Endpoint Intelligence Popular source for obtaining endpoint and vulnerability intelligence Provides a rich “snapshot” of endpoint assets and vulnerabilities Intelligence degrades in between active scans Active scanning can be “harmful” to some hosts Scan occurs Accuracy decay Time Quality t - Coherence time t
10 The Role of Network Behavior Analysis (NBA) “Passive” Endpoint Intelligence Compliments “rich” intelligence gained by active scanning 24x7 monitoring for endpoint assets and vulnerabilities Analogous to passive SONAR—learn by listening Network Anomaly Detection Create a baseline of “normal” network behavior Identify propagation of attacks that “walked” through the front door
11 The Role of Network Access Control (NAC) Pre-connect NAC Dominated by Cisco Network Admission Control (CNAC) & Microsoft Network Access Protection (MNAP) standards Useful for determining “who” can get on the ride Post-connect NAC Useful for determining “what” you can do once you’re on the ride Set compliance policies related to usage of operating systems, services, apps, resources, etc. Identifies policy and regulatory non- compliance
12 Tying It All Together Integrated ETM Console Monitor for security events originating from both inside and outside the organization Correlate threat, endpoint, and network intelligence Threat intelligence from IPS Endpoint intelligence from VA & NBA Network intelligence from NBA Drastically reduce false positives and negatives Monitor for compliance with IT policies related to company, industry and/or government regulatory compliance Compliance monitoring through post-connect NAC
13 ETM—Before, During & After the Attack BEFORE AN ATTACK Everything on the network Policy Violations and Vulnerabilities By Hardening Assets DURING AN ATTACK The Attack The Impact By Blocking and Alerting AFTER AN ATTACK Where the Attack Occurred What Action to Take By Minimizing the Impact

15 ETM—a Better, More Efficient Process Organizations need systems that can analyze security information and apply context automatically and holistically. Most security technologies are driven by a man-in-the loop process. How do you know when to update your access control configuration? How do you know when a new vulnerability is relevant to your environment? How do you know when there is an active, high priority security event occurring in your environment? How do you know when the patch management system needs to address a new host? This information is then turned into response manually Persistent, automatic intelligence generation and analysis driving network security to: REAL-TIME, UNIFIED, NETWORK DEFENSE
16 ETM Benefits Summary Enjoy continuous protection through an integrated approach. The whole truly is greater than the sum of the parts—reduce number of vendors, reduce cost of ownership Get faster and more accurate response from threat, endpoint, and network intelligence—the keys to driving next-generation security technologies that are automated and adaptive Take advantage of consolidated reporting and management views Enforce compliance of security policies and industry regulations as part of overall network protection
17 ETM Take-away ETM leverages real-time intelligence about the network environment and drives it into network security technologies for a more effective and efficient security solution.
