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

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>>

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
IS Event and IS IncidentIS Event (Cont.)
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

Approach to ISIMP DevelopmentIS Incident Management Policy
• The importance of IS incident management• IS events detection, alerts and notification
about IS incidents procedures• Summary of activities following the
confirmation that an IS event is an IS incident• Structure of IS incidents management• List of legal acts being used
Approach to ISIMP DevelopmentIS Incidents Management Process• Vulnerabilities, IS events and incidents (VEI)
detection• VEI notification• VEI messages processing• Reaction to IS incidents• IS incidents analysis• IS incidents investigation• ISIMP efficiency analysis
