Explanation

STRIDE is correct because it was specifically designed to systematically categorize and identify threats across all components of a software system - each element in a data flow diagram is evaluated against all six threat categories (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege), making it inherently systemic in coverage. PASTA (Process for Attack Simulation and Threat Analysis) is an attacker-centric, risk-based approach focused on simulating attack scenarios rather than comprehensive systemic enumeration. VAST (Visual, Agile, and Simple Threat Modeling) is optimized for scaling across Agile/DevOps workflows and organizational processes, not specifically for deep systemic software threat identification. OCTAVE (Operationally Critical Threat, Asset, and Vulnerability Evaluation) targets organizational and operational risk from a business-asset perspective, making it less suited to software-specific systemic analysis.

Memory tip: Think STRIDE = Systematic - the S in STRIDE can remind you it applies a Structured, Systematic sweep across every software component, while the others are either attacker-focused (PASTA), agile-scaled (VAST), or org-level (OCTAVE).
