  1. Assessment Presentation Fundamentals of Information Systems Security Philip Robbins - July 14, 2012 University of Phoenix Hawaii Campus

  2. Scope & Applicability • UOPX Courses • CIS 207Information Systems Fundamentals • CMGT 244Intro to IT Security • CMGT 245IS Security Concepts • CMGT 400Intro to Information Assurance & Security • CMGT 440Intro to Information Systems Security • CMGT 441 Intro to Information Systems Security Management • CMGT 430Enterprise Security • CMGT 442Information Systems Risk Management

  3. Objectives • Review of Concepts. What is (are): • Information Systems? • Information Security? • Information Systems Security? • Information Assurance? • Cyber Security? • Defense in Depth? • Significance / Importance of Concepts • Advanced Topics in Security Risk Analysis • Present & Future Challenges • Q&A

  4. Who am I? • Information Systems Authorizing Official Representative • United States Pacific Command (USPACOM) • Risk Management Field • Assessments to USPACOM Authorizing Official / CIO • Former Electronics Engineer • Bachelor of Science in Electrical Engineering • Master of Science in Information Systems • Ph.D. Student in Communication & Information Sciences • Certified Information Systems Security Professional (CISSP) and Project Management Professional (PMP)

  5. Review of Concepts • What are Information Systems? • Systems that store, transmit, and process information. + • What is Information Security? • The protection of information. ------------------------------------------------------------------------------- • What is Information Systems Security? • The protection of systems that store, transmit, and process information.

  6. Review of Concepts • What is Information Assurance? • Emphasis on Information Sharing • Establishing and controlling trust • Authorization and Authentication (A&A) • What is Cyber Security? • Protection of information and systems within networks that are connected to the Internet.

  7. Review of Concepts • Progression of Terminology • Computer Security • (COMPUSEC) • Legacy Term (no longer used). • Information Security • (INFOSEC) • Legacy Term (still used). • Information Assurance • (IA) • Term widely accepted today with focus on Information Sharing. • Cyber Security • Broad Term quickly being adopted.

  8. Review of Concepts • What is the Defense in Depth Strategy? • Using layers of defense as protection. • People, Technology, and Operations. • Onion Model

  9. Review of Concepts

  10. ISS Management • What is a Backup Plan (BP) vsDisaster Recovery Plan (DRP) vsEmergency Response Plan (ERP) vsBusiness Recovery Plan (BRP)vsBusiness Impact Analysis (BIA) vsIncident Response Plan (IRP) vsContinuity of Operations Plan (COOP) vsContingency Plan? • Policy & Planning • Test, Audit, Update • Configuration Control • Protection, Detection, Reaction • (Assessment, CND, Incident Response)

  11. Why is this important? • Information is valuable. therefore, • Information Systems are valuable. • etc… • Compromise of Information Security Services (C-I-A) have real consequences (loss) • Confidentiality: death, proprietary info, privacy, theft • Integrity: theft, disruption • Availability: productivity lost, C2, defense, emergency services

  12. Why is this important? • Fixed Resources • Sustainable strategies reduce costs

  13. Advanced Topics: Measuring Risk • What is Risk? • thus • Qualitative v.s. Quantitative Methods • Risk Assessments v.s. Risk Analysis • Security Risk Analysis (SRA) • Units for measurement?

  14. Advanced Topics: Measuring Risk • Risk is conditional, NOT independent.

  15. Advanced Topics: Measuring Risk • Quantitative, time-dependent (continuous), • Risk Distribution Function: Source: Robbins, P. (Dec, 2011). Security Risk Analysis and Critical Information Systems (Master's Thesis). Hawaii Pacific University, Honolulu, HI.

  16. Advanced Topics: Measuring Risk • Expected Value of Risk = Product of Risks • Risk is never zero • Risk Dimension (units): confidence in ISS, C-I-A

  17. Advanced Topics: Measuring Risk • Expected Value and Risk Loss Confidence vs Cumulative Risk Product

  18. Advanced Topics: Measuring Risk • Quantitative Risk Determination Expression • Risk Rate & Risk Variability • Adjudication of Risk

  19. Advanced Topics: Measuring Risk • Determining Risk Tolerance / Threshold Levels

  20. Advanced Topics: Measuring Risk • Risk Areas as a function of Probability and Impact

  21. Present Challenges • Rapid growth of Advanced Persistent Threats (APTs) • Half million cases of cyber related incidents in 2012. • Is this a problem? • What about vulnerabilities • associated with • interconnections? Source: US-CERT

  22. Future Challenges • Cyberspace: Are we at war? • Cyber Crime vs Cyber Warfare vs Cyber Conflict

  23. Closing Thoughts • Information Systems Security (Cyber Security) is an explosive field. - Spanning Commercial, Private and Government Sectors - Demand >> Capacity: Strategies, solutions, workforce - $ - Evolving field (not fully matured) • Security will change our communications landscape - Efficiencies (centralization of services, technology) - Intelligent design of network interconnections and interdependencies - Regulations
