SECURITY DECISION RECORD
Context: The 2013 incident and subsequent MDL litigation (No. 14-2522) required clear decisions on architecture and governance for vendor access and payment-environment segmentation. The court’s pleading-stage opinion increased pressure for auditable remediation evidence. This decision sets the selected model for consistent controls and legal defensibility.
Options Considered: (1) Mandate monitored jump-host pathways plus segmentation baselines for store environments (selected). (2) Vendor-by-vendor custom access controls—rejected due to inconsistency and audit complexity. (3) Deferral until hardware refresh cycles—rejected for unacceptable interim risk.
Rationale: The selected option best balances speed, control uniformity, and evidentiary clarity. Inputs included forensic findings, card-brand control expectations, and deployment constraints across store networks.
Commitments: Rollout milestone gates through Q4 2015; monthly remediation aging review; governance exceptions require CISO approval and documented compensating controls.
