Initial Response Metrics

Track key metrics to improve response effectiveness:

Time to detection (TTD)
Time to triage (TTT)
Time to containment (TTC)
False positive rate
Alert response rate
Escalation accuracy

Effective detection and initial response form the foundation of successful incident handling. By implementing robust detection capabilities, establishing clear response procedures, and maintaining readiness through training and automation, organizations can minimize the impact of security incidents. The next chapter will explore the critical processes of digital evidence collection and preservation, building on the initial response actions covered here.## Digital Evidence Collection and Preservation

Digital evidence forms the backbone of any forensic investigation and can be crucial for legal proceedings, internal investigations, and understanding the full scope of a security incident. This chapter provides comprehensive guidance on properly collecting, preserving, and handling digital evidence while maintaining its integrity and admissibility. From volatile memory to cloud storage, we'll explore the methodologies and tools necessary for forensically sound evidence handling.
