  3. 3. Foundations of Information Security Series  Needs  Secrecy  Intellectual Property you Own  Intellectual Property you Use  Privacy  Availability  Retention  Expiration  Quality  Obligations  Technical  Compliance  Legal
  4. 4. What is Information Security?  “Information Security” is an emergent property of people using information.  People have expectations about information.  If there is no people or no information, “Information Security” is meaningless, as there are no expectations to meet.
  5. 5. What is Information Security?  When expectations about information are met, there is “Security”.  When expectations about information are not met, there is an “Incident”.
  6. 6. What is Information Security?  Some expectations are things people (or organizations) want to happen for their own reasons. These are Needs.  Some expectations are things people (or organizations) want to happen in order to meet technical, legal or standard compliance requirements. These are Obligations.

  8. 8. Technical Obligations  Information systems based on the Von-Neumann architecture have inherent technical limitations that lead to weaknesses. This weaknesses can be exploited and lead to failing to meet other, more important, expectations. This is why organizations have the expectation that:  Information systems are kept free of weaknesses.  Information systems that need to be visible from not trusted systems are the least visible possible.  That information systems run trusted software only.  That electricity, temperature and humidity within controlled limits necessary for the operation of information systems.
  9. 9. Technical Obligations  If these expectations are met or not is independent of the observer.
  10. 10. Technical related incidents  When an information system presents a weakness.  When an information system is visible from not trusted systems.  When an information system runs not trusted software.  When electricity, temperature or humidity are out of controlled limits.
  11. 11. Achieving Technical Security  In order to achieve Technical Security, normally architecture, design, and specific software and appliances are used.  The related O-ISM3 process are:  OSP-5: IT Managed Domain Patching  OSP-7: IT Managed Domain Hardening  OSP-8: Software Development Lifecycle Control  OSP-16: Segmentation and Filtering Management  OSP-17: Malware Protection Management  OSP-14: Physical Environment Protection Management  OSP-19: Internal Technical Audit  OSP-22: Alerts Monitoring  OSP-23: Internal Events Detection and Analysis
