SECURITY ARCHITECTURE EXPLANATION FOR LEGAL REVIEW
Scope: This memo summarizes the security architecture relevant to legal review and disclosure support for In re Target Corp. MDL. It focuses on trust boundaries, control design, and evidence availability, with reference to the district court opinion reported at 66 F. Supp. 3d 1154 and related litigation-driven evidence requirements.
Architecture Overview: The architecture under review includes point-of-sale endpoints, store network segments, vendor remote-access pathways, and corporate processing environments. Trust boundaries are defined between store systems, payment-card processing components, and enterprise services. Post-incident efforts focus on reducing implicit trust across vendor and store connectivity.
Security Controls (Post-Remediation): (1) Perimeter and segmentation. Segmented store and processing networks with controlled inter-zone routing. (2) Access. Vendor access governance via approved remote pathways and privileged control policies. (3) Data. Payment and customer data protection controls with encryption and key-handling requirements. (4) Monitoring. Centralized log retention and alerting on lateral movement and anomalous export behavior.
Incident Vector and Remediation: Public reporting described malware activity in POS environments and abuse of trust paths involving remote access and segmented networks. Remediation includes gold-image controls, stronger vendor session governance, and expanded forensic logging. Residual risk remains in legacy store environments and third-party dependencies; mitigations include exception governance, periodic testing, and incident runbook drills.
Assumptions and Limitations: This memorandum is accurate as of the date above and supports legal review, not a guarantee of complete security. Additional technical detail is available in architecture diagrams, network maps, and control-test records.
