# Runbook - 07 Audit Evidence With Data Safe
## Objective
Show how to turn access to sensitive data into auditable evidence using Unified Audit and OCI Data Safe.
## Security Value
- Shows that prevention should be paired with evidence.
- Helps CISO, audit, and compliance teams monitor access to sensitive data.
- Demonstrates how Data Safe complements Oracle Deep Data Security with activity auditing and reporting.
## Prerequisites
- Oracle Database compatible with Unified Audit.
- OCI Data Safe enabled in the tenancy.
- Target database registered, or ready to be registered, in Data Safe.
- Permissions to configure Activity Auditing.
## Before - Vulnerable Environment
1. Reset the scenario:
```sql
@scenarios/07-audit-evidence-data-safe/sql/99_reset.sql
```
2. Create the sensitive table, data, and personas without custom auditing or data grants:
```sql
@scenarios/07-audit-evidence-data-safe/sql/00_schema.sql
@scenarios/07-audit-evidence-data-safe/sql/01_seed_data.sql
@scenarios/07-audit-evidence-data-safe/sql/02_identities.sql
```
3. Run a broad payments query:
```sql
SELECT payment_id, customer_name, country, payment_amount, card_token, risk_flag
FROM dds_audit_payments
ORDER BY payment_id;
```
## Expected Result Before
- `CARD_TOKEN` can be queried by users with broad access.
- The team may struggle to quickly prove who accessed the table and when.
- There is no clear evidence package for audit.
## After - Applying Deep Data Security And Auditing
1. Apply the data grants:
```sql
@scenarios/07-audit-evidence-data-safe/sql/03_data_grants.sql
```
2. Create Unified Audit policies:
```sql
@scenarios/07-audit-evidence-data-safe/sql/04_audit_policies.sql
```
3. Apply redaction to the payment token column:
```sql
@scenarios/07-audit-evidence-data-safe/sql/06_redaction_policy.sql
```
4. Generate activity and query the local audit trail:
```sql
@scenarios/07-audit-evidence-data-safe/sql/05_generate_activity.sql
```
5. In OCI Data Safe:
```text
Register Target Database
Configure Activity Auditing
Start audit trail collection for UNIFIED_AUDIT_TRAIL
Review the Activity Auditing dashboard
Generate or export an audit report
```
## Expected Result After
- `payment_operator` sees operational Brazil payment fields without `card_token`.
- `auditor` sees the data required for review, with `card_token` partially redacted.
- `UNIFIED_AUDIT_TRAIL` records access to `DDS_AUDIT_PAYMENTS`.
- Data Safe collects and presents events in dashboards and reports.
## Demo Evidence
- Output from `UNIFIED_AUDIT_TRAIL`.
- Screenshot of the Data Safe target.
- Screenshot of Activity Auditing.
- Exported Data Safe report, when available.
