Auditability & Traceability - AMOS Data Platform Documentation

Complete Transparency for Regulatory Confidence

In the highly regulated fund management industry, auditability isn’t optional—it’s essential. Amos provides unprecedented transparency through open source practices, version-controlled configurations, and comprehensive audit trails that exceed traditional vendor capabilities. Every data transformation, configuration change, and system access is tracked, versioned, and auditable.

Version-Controlled Configurations

Git-Based Configuration Management

All Amos configurations are stored in Git repositories, providing complete change history and accountability:

# Example: Fund configuration with full audit trail
fund_configuration:
  version: "2.1.3"
  last_modified: "2024-01-15T10:30:00Z"
  modified_by: "john.doe@examplefund.com"
  approved_by: "jane.smith@examplefund.com"
  
  data_sources:
    fund_admin:
      system: "SS&C Advent"
      connection_type: "API"
      refresh_schedule: "daily_6am"
      data_retention: "7_years"
      
  transformations:
    nav_calculation:
      model: "models/nav/daily_nav.sql"
      version: "1.2.1"
      last_tested: "2024-01-14T15:45:00Z"
      test_results: "all_passed"

Change Audit Trail

Every configuration change creates a permanent audit record:

Who Changed What

Complete identity tracking for every modification with digital signatures and approval workflows.

When Changes Occurred

Precise timestamps for all changes with timezone and system correlation information.

Why Changes Were Made

Required change descriptions, ticket references, and business justification documentation.

How Changes Were Tested

Automated test results and validation evidence before production deployment.

End-to-End Data Lineage

Complete Data Flow Visibility

Amos automatically tracks data lineage from source systems through all transformations to final reports:

Lineage Documentation

For every data element in your reports, you can trace:

Audit Question	Amos Answer	Evidence Location
Where did this data originate?	Source system, table, and field identification	`lineage/source_mapping.json`
How was it transformed?	Complete transformation logic and business rules	`models/transformations/*.sql`
When was it last updated?	Exact refresh timestamps and processing duration	`logs/pipeline_execution.log`
Who approved the logic?	Code review history and approval signatures	`git log --show-signature`
What tests validated it?	Automated test results and data quality checks	`tests/results/*.json`

Reproducibility & Evidence Packs

Reproducible Builds

Every Amos deployment and data processing run is completely reproducible:

Infrastructure Reproducibility

terraform {
  required_version = "1.6.0"
  
  backend "s3" {
    bucket = "your-fund-terraform-state"
    key    = "amos/production/terraform.tfstate"

  --period "2023-01-01,2023-12-31" \
  --scope "nav_calculation,investor_reporting" \
  --format "regulatory_package" \
  --output "/audit/2023_annual_review/"

# Package contents:
# - Configuration history and approvals
# - Data lineage documentation
# - Processing logs and test results
# - Access control evidence
# - Change management records

Audit Trail Queries

Built-in queries for common audit questions:

-- Who accessed investor data in the last quarter?
SELECT 
  user_id,
  COUNT(*) as access_count,
  MIN(timestamp) as first_access,
  MAX(timestamp) as last_access
FROM audit_logs 
WHERE resource_type = 'investor_data'
  AND timestamp >= '2023-10-01'
GROUP BY user_id;

-- What changes were made to NAV calculations?
SELECT 
  commit_hash,
  author,
  timestamp,
  change_description,
  files_modified
FROM git_audit_log
WHERE file_path LIKE '%nav_calculation%'
  AND timestamp >= '2023-01-01'
ORDER BY timestamp DESC;

Continuous Monitoring & Alerting

Real-Time Audit Monitoring

Amos continuously monitors for audit-relevant events:

Unusual Access Patterns: Automated detection of anomalous user behavior
Configuration Drift: Alerts when systems deviate from approved configurations
Data Quality Issues: Immediate notification of data integrity problems
Security Events: Real-time alerting for potential security incidents

Compliance Dashboard

Executive dashboard showing compliance posture in real-time:

Implementation Best Practices

Audit-First Design

When implementing Amos, consider audit requirements from day one:

Define Audit Scope: Identify what needs to be auditable
Configure Logging: Set up comprehensive audit logging
Establish Procedures: Create audit evidence collection procedures
Train Teams: Ensure staff understand audit requirements
Test Regularly: Conduct mock audits to validate evidence quality

Evidence Retention Strategy

Develop a comprehensive evidence retention strategy:

Configuration History: Retain indefinitely for regulatory compliance
Processing Logs: 7+ years for most fund regulations
Access Logs: 3-7 years depending on jurisdiction
Test Results: Retain with associated code versions
