Old Presentation on Security Metrics 2005 Presentation Transcript

  • 1.
    • Metrics: Optimizing Security Operations Performance
    • Dr Anton Chuvakin
    • Chief Security Strategist
    • November 2005
  • 2. WARNING!
    • This is an old presentation; I am publishing it in the hopes that it will be useful for somebody.
    • I do not necessarily share all the views I held back in 2005!
    • And I ramble less now 
  • 3. Agenda
    • Catalysts for security performance metrics
    • Why security metrics are essential
    • Types of metrics and what to measure
    • Challenges surrounding metrics
    • The metrics lifecycle
  • 4. Catalysts For Security Performance Metrics
    • Enterprise compliance and governance initiatives
    • Need to manage security as a strategic business process
    • Pressure to demonstrate the efficiency of security technology and related efforts
  • 5. Managing Information Security Strategically
    • Compliance has shifted mindset from devices to process
    • Focus on continuous optimization
      • Conduct security assessment
      • Define policies, process, metrics, and baselines
      • Collect data; measure results against baselines over time
      • Identify process and policy weaknesses
      • Refine policy, process, and metrics
  • 6. Creating a Culture of Measurement: Recommendations
    • Define security policies and relevant metrics via security assessment
    • Capture all relevant security operational data
    • Generate reports off the data to measure success and identify performance gaps
    • Integrate security performance management data with enterprise compliance & governance initiatives
  • 7. Why Security Metrics?
    • You need to know if…
    • your security strategies are successful
    • you require more resources
    • there are in-efficiencies
    • you are compliant
    “ You can’t manage what you can’t measure”
  • 8. Types of Metrics
    • Technical
      • eg: Percentage of systems with virus protection
    • Process
      • eg: Average virus incident resolution time
    • Risk
      • eg: Risk of viruses for a specific business unit
    • Cost
      • eg: Average cost of virus incident
  • 9. Criteria for Good Metrics
    • When determining the metrics that you will track, be SMART…
    • S pecific
    • M easurable
    • A ttainable
    • R epeatable
    • T ime-dependent
    • And… your results need to be ACTIONABLE !
  • 10. Metrics and Baselines
    • Baselines are metrics that are compared to aggregated information about the past
    • Common baselines
      • Yesterday (“NASDAQ is up by a 100”)
      • Average (“This took us 3 more time than the average case”)
      • Maximum (“The traffic is spiking 300% over the maximum!”)
    • Baselines enjoy the ease of interpretation !
    What is the difference?
  • 11. Perceived Effectiveness of Metrics Source: CSO Magazine, 2005
  • 12. Key Challenges with Security Metrics
    • “Let’s make up some metrics…”
      • Metrics must be based on policy to be effective
    • Where is the data?
      • Difficulties in acquiring raw data for measurement
    • So many metrics, so little time…
      • Which indicators should we compute and use?
    • What does it mean?
      • Interpreting the changes in measures parameters
    • “Go back and try it again!!!”
      • Challenges with presenting metrics to executives
    • What do we do now?
      • Defining actions and remediation planning
  • 13. Future of Security Metrics
    • “ Information Security Management Metrics and Measurement” ( ISO 27004 ) in 2007-2009
    • Increased adoption of NIST 800-55
    • Legal and compliance drivers for standard metrics
    • Growth of “ best practices ”-based metrics
    • Convergence of security vendor metrics
    • More automation of metrics
    Metrics and Crystal Ball Gazing Don’t Mix, but…
  • 14. Conclusion
    • Security needs to be managed as a strategic business process (bla-bla-bla  )
    • Enterprise compliance and governance initiatives are driving security performance metrics
    • Establishing a security metrics program is essential to determining if
      • your security strategies are successful
      • you are compliant
    • In the future metrics will be based on standards
