FAQs

How can different line types be used in attack path diagrams?

Different line types, such as solid and dotted lines, can be used to represent known and unknown aspects of an incident, conveying clarity in the diagram's visual storytelling.

Are attack path diagrams marked with TLP controls?

Yes, diagrams are marked with TLP (Traffic Light Protocol) controls, particularly for sensitive incidents or information sharing within specific industries, to ensure data protection and opsec.

Do the speakers rely on templates to create attack path diagrams?

The speakers often use pre-built templates to speed up the diagram creation process, modifying existing diagrams from previous incidents to fit the current investigation.

The video provides a comprehensive overview of the use and creation of attack path diagrams in DFIR investigations, including practical examples and considerations to enhance their effectiveness.
