    • 4. Market Environment – General Observations
        • Information security market (products and services)
          • Fragmented, high growth, constantly evolving
          • Information security becoming a component of risk management
        • Typical attitude
          • Information security spending remains a priority
          • Do not want another product to manage
        • Technology
          • Start-up driven innovation
            • Point solutions
          • No silver bullet
            • Lots of process in every solution

    • 6. Market Environment – Information security system
        • Best practices
          • Driven by business requirements
          • Focus on risk reduction
          • Security program driven by policy
          • Management through analysis of metrics
          • Results in business enablement
        • Common shortcomings
          • Focus on technology rather than process
          • Decisions driven by fear
          • Event orientation around regulatory compliance
          • Ad-hoc staffing, responsibilities and policies
          • Restricts business agility, growth and income

    • 8. Market Environment – Information security system
      • Where security programs often go wrong
        • Flawed understanding environmental conditions
          • Why are so many security products ineffective? Asymmetric information favors attacker
          • Failure to recognize that:
            • Trust management is an arms race, risk management is manageable (and manageable at a profit)
            • Risk control encapsulates trust
        • Flawed understanding security system requirements
          • Primary system requirements are always security, scalability and integration
          • Only platform vendors can deliver security that is integrated enough to scale and invisible enough to ignore
        • Flawed understanding of process
          • Security is a means and not an end

SP 800-53A ASSESS Security Controls Define criticality/sensitivity of information system according to potential worst-case, adverse impact to mission/business. FIPS 199 / SP 800-60 CATEGORIZE Information System Continuously track changes to the information system that may affect security controls and reassess control effectiveness. SP 800-37 / SP 800-53A MONITOR Security State SP 800-37 AUTHORIZE Information System Determine risk to organizational operations and assets, individuals, other organizations, and the Nation; if acceptable, authorize operation. Implement security controls within enterprise architecture using sound systems engineering practices; apply security configuration settings.
