5 IBM W7+2 methodology Who : Which person or application generated the action What: What action was performed When: When did the event happened ( absolute and relative time) Where: On which object it happened? Where From: From which object was the action initiated Where To: Which object was the target of the action On What: Which object was impacted + With Whom: Who were the collaborators in the activity Why: Goal of the activity Where Where from Where to Maps intuitively to the Extended Diamond Model of Intrusion Analysis Who With Whom Why On What (Targets) When What Kill chain steps 5 IBM Security

8 Points of automation in investigations tasks Automated Data Load and Update for High Value Targets (protected entities, data, critical systems, VIP persons) Investigation workflows can be triggered by: Proactive: Threat Intelligence alerts ( threat feeds and unstructured data) Real time: SIEM monitoring, offense investigation ( L3) Post attack: forensics investigations, manual eventss Set of connectors and connector framework for AdHoc queries for selected data classes SIEM, Asset DB, IDM, Service models, Endpoints protections, Threat services, etc. Predefined Investigation workflow following Diamond model methodology ( focus questions, roles, tasks, data integrations, result artifacts) Use case updates to SIEM (with results artifacts and automated updates) Up-to-date reporting, evidence collection and dashboard The investigation is supported, structured and accelerated by a methodology and related automation tools with AI support, but done by a human analyst. 8 IBM Security

Statement of Good Security Practices: IT system security involves protecting systems and information through prevention, detection and response to improper access from within and outside your enterprise. Improper access can result in information being altered, destroyed, misappropriated or misused or can result in damage to or misuse of your systems, including for use in attacks on others. No IT system or product should be considered completely secure and no single product, service or security measure can be completely effective in preventing improper use or access. IBM systems, products and services are designed to be part of a lawful, comprehensive security approach, which will necessarily involve additional operational procedures, and may require other systems, products or services to be most effective. IBM does not warrant that any systems, products or services are immune from, or will make your enterprise immune from, the malicious or illegal conduct of any party.
