3. Organization • Introduction • International Documents Regulating IS Incidents and Management • IS Event and IS Incident • Approach to ISIMP Development • VEI Detection and Notification Joint Process • Conclusions

4. IntroductionWhy ISIMP? • Detect, report and assess IS incidents • Respond to IS incidents • Learn from IS incidents

5. IntroductionWhy ISIMP? • One of the basic parts of ISMS • Data obtained from ISIMP can be used in other ISMS’ processes • Helps assess the overall level of organization’s IS

6. Organization Introduction International Documents Regulating IS Incidents and Management IS Event and IS Incident Approach to ISIMP Development VEI Detection and Notification Joint Process Conclusions 6

7. International Documents Regulating IS Incidents and Management • The Standard ISO/IEC 27001 “Information technology – Security techniques – Information security management systems – Requirements” • NIST SP 800-61 <<Computer security incident handling guide>> • CMU/SEI-2004-TR-015 <<Defining incident management processes for CSIRT>>

9. IS Event and IS IncidentIS Event • IS Event • An identified occurrence of a system, service or network state indicating a possible breach of IS policy or failure of safeguards

10. IS Event and IS IncidentIS Event (Cont.)

11. IS Event and IS IncidentIS Incident • IS Incident • Is indicated by a single or a series of unwanted or unexpected IS events that have a significant probability of compromising business operations and threatening IS

12. IS Event and IS IncidentIS Incident (Cont.)
