3. The Problem

4. 1. What causes the damage? 2. How do you prevent the damage? What are your options? • RISK= • Assets x Vulnerabilities x Threats • You can control vulnerabilities. • 95% of breaches target • known vulnerabilities 4. How do you make the best security decisions? 3. How do you successfully deal with vulnerabilities? • Vulnerabilities • Business complexity • Focus on the right assets, right threats, right measures. • Human resources • Financial resources Organizations are Feeling the Pain

5. What is Vulnerability Management?

6. What Is Vulnerability Management (VM) A process to determine whether to eliminate, mitigate or tolerate vulnerabilities based upon risk and the cost associated with fixing the vulnerability. Methodologies Available for VM: Vulnerability Analysis (VA) Penetration Tests (PT) DAST (Dynamic Application Security Test) SAST (Static Application Security Test)

7. What Is Vulnerability Management At a high level, the “intelligent confluence” of… Assessment What assets? Analysis What to fix first? Remediation Fix the problem + + • As a component of Risk Management • And balance the demands of business goals and processes

8. Difference between Vulnerability Assessment & Vulnerability Management • Vulnerability Assessment: • One time project with defined start and end date. • External IS Consultant studies network, prepares report and assessment ends. • Report lists identified vulnerabilities and provide actionable recommendations for remediation. • Vulnerability Management: • Ongoing/continuous process that aims at managing an organization’s vulnerabilities in a holistic manner. • Assessment is continuously done in a cyclic/scheduled manner of critical assets & vulnerabilities identified are reported for further action.

9. Challenges to Effective VM

10. Challenges – Assessment • Handling large networks• Scan distribution is cumbersome• Time consuming and resource intensive• Compliance challenges

11. Challenges – Analysis • Manual and resource intensive process to determine • What to fix • If you should fix • When to fix • Correlation between vulnerabilities, threats and assets • A way to prioritize what vulnerabilities should be addressed • What order • Avoiding Stale data • Making decisions on last quarter’s vulnerabilities • Creating credible metrics

12. Challenges – Remediation • Security resources are often decentralized • The security organization often doesn’t own the network or system • Multiple groups may own the asset • Presenting useful and meaningful information to relevant stakeholders • Determining if the fix was actually made

13. Asset Any equipment or device or end-point (identifiable using an IP) that has value to the organization or supports the ability of the organization to conduct business

14. Threat Any person, circumstance or event that has the potential to cause damage to an organizational asset or business function

15. Vulnerability Any flaw in the design, implementation or administration of a system that provides a mechanism for a threat to exploit the weakness of a system or process

16. Cost to ignore vulnerability is greater than the cost to repair Challenges – Time • Threat Level • Asset Criticality • Risk Threshold • Vulnerability • discovered • Exploit • public • Automated • exploit • Remediation • Discovery

17. Goal = compress time from discovery to remediation • Cost to ignore vulnerability is greater than the cost to repair • Cost to ignore vulnerability is greater than the cost to repair • Remediation • Discovery Challenges – Time • Threat Level • Asset Criticality • Risk Threshold • Automated • exploit • Exploit • public • Vulnerability • discovered

18. Goal = compress time from discovery to remediation • Cost to ignore vulnerability is greater than the cost to repair • Remediation • Discovery Challenges – Time • Threat Level • Asset Criticality • Risk Threshold • x 15 new vulnerabilities per day across many assets • Automated • exploit • Exploit • public • Vulnerability • discovered

19. Vulnerability Management Lifecycle

20. Vulnerability Management Lifecycle

21. Successful Approaches: Implementing An Effective VM Strategy

22. Successful Approaches • Focus on four key areas: • Prioritize Assets • Determine Risk Level (assets, threats, vulnerabilities) • Remediate Vulnerabilities • Measure

23. Prioritize Assets

24. Asset Prioritization • Identify assets by: • Networks • Logical groupings of devices • Connectivity - None, LAN, broadband, wireless • Network Devices • Wireless access points, routers, switches • Operating System • Windows, Unix • Applications • IIS, Apache, SQL Server • Versions • IIS 5.0, Apache 1.3.12, SQL Server V.7

25. Asset Prioritization • Network-based discovery • Known and “unknown” devices • Determine network-based applications • Excellent scalability • Agent-based discovery • In-depth review of the applications and patch levels • Deployment disadvantages • Network- and agent-based discovery techniques are optimal • Agents - Cover what you already know in great detail • Network - Identify rogue or new devices • Frequency • Continuous, daily, weekly • Depends on the asset

26. Correlate Threats

27. Correlate Threats (with your critical assets) • Not all threat and vulnerability data have equal priority • Primary goal is to rapidly protect your most critical assets • Identify threats • Worms • Exploits • Wide-scale attacks • New vulnerabilities • Correlate with your most critical assets • Result = Prioritization of vulnerabilities within your environment

28. Determine Risk Level

29. Risk Calculation • The Union of: • Vulnerabilities • Assets • Threats • Based upon the criticality of VAT • Focus your resources on the true risk

30. Remediation

31. Remediation / Resolution • Perfection is unrealistic (zero vulnerabilities) • Think credit card fraud – will the banks ever eliminate credit card fraud? • You have limited resources to address issues • The question becomes: • Do I address or not? • Factor in the business impact costs + remediation costs • If the risk outweighs the cost – eliminate or mitigate the vulnerability!

32. Remediation / Resolution • Apply the Pareto Principle – the 80/20 rule • Focus on the vital few not the trivial many • 80% of your risk can be eliminated by addressing 20% of the issues • The Risk Union will show you the way • Right assets • Relevant threats • Critical vulnerabilities • Patch or Mitigate • Impact on availability from a bad patch vs. the risk of not patching • Patch or mitigate • Recommendations: • QA security patches 24 hours • Determine if there are wide spread problems • Implement defense-in-depth

33. Measure

34. Measure • Nemasis OutLook: • Distribute Accountability (based on Asset, Asset-owner, Group) • A universal standard to quantify risk (CVSS) • Dashboard view of risk and vulnerabilities • Nemasis will help answer the questions: • Am I secure? • Who is accountable and by when? • Am I getting better or worse? • How am I trending over time?

35. Summary • All assets are not created equally • You cannot respond to or even protect against all threats • An effective vulnerability management program focuses on Risk • Vulnerabilities • Assets • Threats • The hardest step in a 1000 mile journey is the first – start somewhere • Strategically manage vulnerabilities using a comprehensive process

36. 10 Steps to Effective Vulnerability Management • Identify all the assets in your purview • Create an Asset Criticality Profile (ACP) • Determine exposures and vulnerabilities • Track relevant threats – realized and unrealized • Determine Risk - union of vulnerabilities x assets x threats • Take corrective action if risk > cost to eliminate or mitigate • Create meaningful metrics • Identify and address compliance gaps • Implement an automated vulnerability management system • Convince customer that vulnerability management is important
