🎯 TEST CATEGORIES

SECTION 1: SOX Section 404 Compliance (10 Tests)

Test 1: Audit Trail Immutability - Tamper Detection

Purpose: Verify cryptographic checksums detect unauthorized audit log modifications
Key Validations:

• ✅ Events written with SHA-256 checksums
• ✅ Retrieved events verified against stored checksum
• ✅ Simulated tampering detected (user_id modification)
• ✅ Integrity check fails for tampered events

Regulatory Requirement: SOX Section 404 (Internal Controls)
Test Scenario:

// 1. Write event with checksum
audit_engine.record_event(event).await;

// 2. Retrieve and verify checksum
let retrieved = audit_engine.query_events(query).await;
assert!(retrieved[0].checksum.is_some());

// 3. Simulate tampering (change user_id)
event.user_id = "bob"; // Unauthorized modification

// 4. Verify tampering detected
let tamper_detected = audit_engine.verify_event_integrity(&event).await;
assert!(!tamper_detected, "Should detect tampering");

Expected Result: Tampered events fail integrity verification

---

Test 2: 7-Year Retention Enforcement

Purpose: Validate audit logs retained for SOX-mandated 7-year period
Key Validations:

• ✅ Events 6 years old: Retained
• ✅ Events exactly 7 years old: Retained (threshold)
• ✅ Events 8 years old: Purged (beyond threshold)

Regulatory Requirement: SOX Section 404 (7-year retention)
Test Scenario:

// Create events with different ages
let six_years_ago = now - Duration::days(6 * 365);
let seven_years_ago = now - Duration::days(7 * 365);
let eight_years_ago = now - Duration::days(8 * 365);

// Apply retention policy
audit_engine.apply_retention_policy().await;

// Verify retention thresholds
assert!(query_event("RET6YR").len() == 1, "6-year retained");
assert!(query_event("RET7YR").len() == 1, "7-year retained");
assert!(query_event("RET8YR").len() == 0, "8-year purged");

Expected Result: Exactly 7-year retention enforced

// Unauthorized access (Trader)
let unauthorized = audit_engine.query_events_with_access_control(
    query, "trader", vec!["EXECUTE_TRADES"]
).await;
assert!(unauthorized.is_err(), "Trader should be denied");

let modification = audit_engine.modify_event_with_access_control(
    "ACCESS001", "admin", vec!["ADMIN"]
).await;
assert!(modification.is_err(), "Audit logs immutable");

Expected Result: Strict RBAC enforcement, no modifications allowed

---

Test 4: Checksum Integrity Detection

Purpose: Validate SHA-256 checksums detect any audit record modifications
Key Validations:

• ✅ Untampered records: Valid checksum

assert!(valid_checksum, "Untampered checksum valid");

// Negative test: Simulate storage-level tampering
tampered_event.risk_level = RiskLevel::Critical; // Change risk level
audit_engine.simulate_storage_tampering("CHECKSUM001", tampered_event).await;

let invalid_checksum = audit_engine.verify_event_checksum("CHECKSUM001").await;
assert!(!invalid_checksum, "Tampered checksum invalid");

Expected Result: All modifications detected via checksum mismatch

    if i == 500 {
        audit_engine.simulate_failure(5000).await; // 5s outage
    }
}

// Verify all events archived
let archived = audit_engine.query_events(query).await;
assert_eq!(archived.len(), 1000, "All events archived");

// Verify no gaps in sequence
for i in 0..1000 {
