SECURITY ARCHITECTURE EXPLANATION FOR LEGAL REVIEW
Scope: This memo summarizes the security architecture relevant to legal review and disclosure support for Altaba / Yahoo SEC (2018). It focuses on trust boundaries, control design, and evidence availability, with reference to the SEC administrative order of April 24, 2018 (File No. 3-18448).
Architecture Overview: The architecture in scope includes incident-detection telemetry, identity and account services, evidence-retention pipelines, and governance interfaces to legal and finance disclosure workflows. Trust boundaries are defined across security operations systems, incident response case management, and reporting control channels used for securities disclosures.
Security Controls (Post-Remediation): (1) Perimeter and detection controls. Monitoring on account-facing services and incident triage workflows. (2) Access. Controlled administrative access to incident evidence and disclosure-support systems. (3) Data. Retention policies and legal-hold controls for logs and investigative artifacts. (4) Monitoring. Alerting and escalation checkpoints tied to disclosure-control procedures.
Incident Vector and Remediation: The SEC order emphasized delay between internal confirmation of unauthorized access and investor-facing disclosure. Remediation focuses on architecture-level support for timely escalation, evidence integrity, and cross-functional review. Residual risk remains in manual handoffs and legacy logging islands; mitigations include workflow automation, retention controls, and testing of disclosure controls.
Assumptions and Limitations: This summary is accurate as of the date above and intended for legal review. It does not guarantee invulnerability. Additional architecture diagrams, runbooks, and evidence maps are available to counsel.
