Security and Infrastructure Documentation Template for Solutions Managing PII and Sensitive Data WQRR

# Security and Infrastructure Documentation Template for Solutions Handling PII This documentation outlines the necessary components for demonstrating an organization's implementation of security controls, infrastructure setup, data flows, and storage practices, with a focus on Personally Identifiable Information (PII) and sensitive data. --- ## Infrastructure - **Diagram Requirements:** Visually represent infrastructure components, their interconnections, and boundaries clearly. - **Stability:** Include hardware and software redundancies alongside failover mechanisms for critical infrastructure components. - **Reliability:** Provide uptime metrics, maintenance schedules, and downtime windows. - **Security:** Detail implemented security tools, network security boundaries, and zones. - **Change Management:** Document change request workflows, approval processes, and segregation of environments (Dev, QA, Staging, Production). ## Security - **Access Control:** Define user roles, authentication, and authorization procedures. - **Encryption:** Specify data-at-rest encryption methods and protocols used for data-in-transit. - **Network Security:** Highlight firewall placements and Intrusion Detection/Prevention Systems (IDS/IPS). - **Production Access:** Identify who has production access, the purpose, and access review and revocation policies. - **Audit Logging:** Illustrate logging mechanisms, log storage, and retention policies. - **External Audits:** List compliance certifications (e.g., SOC2, ISO 27001) and results of past audits including penetration tests and vulnerability scans. - **Web Application Firewall (WAF):** Show the placement of WAF in the architecture. ## Availability - **Data Flow:** Clearly show points of data flow and replication. - **Backup:** Describe backup schedules and offsite backup locations. - **Active-Active Availability:** Mention multiple active instances for load balancing and geographical distribution. - **Snapshots:** Document snapshot frequency and retention periods. ## Scalability - **Performance:** Explain load balancing mechanisms and performance optimization measures such as caching. - **Storage:** Detail storage types (SSD, HDD) used, data growth forecasts, and expansion plans. ## Example Diagrams - Provide system diagrams for these areas: - Infrastructure - Security - Availability - Scalability --- **Note:** The system diagram must clearly depict the flow of PII within your solution to adequately demonstrate the handling and protection of sensitive data. Use this documentation framework to create comprehensive security and infrastructure documentation for your solution that conforms to regulatory and compliance needs while ensuring robust protection and availability of critical systems.
