# Runbook - 02 Shared App Account
|
|
|
|
## Objective
|
|
|
|
Show that a shared technical application account should not be the real data authorization boundary.
|
|
|
|
## Security Value
|
|
|
|
- Reduces the risk of overprivileged connection pools.
|
|
- Lets the database evaluate the end user, not only the technical account.
|
|
- Helps protect web applications, APIs, BI tools, and agents that use shared accounts.
|
|
|
|
## Prerequisites
|
|
|
|
- Oracle AI Database compatible with Oracle Deep Data Security.
|
|
- SQLcl or SQL*Plus.
|
|
- Understanding of which end-user identity the application will propagate.
|
|
|
|
## Before - Vulnerable Environment
|
|
|
|
1. Reset the scenario:
|
|
|
|
```sql
|
|
@scenarios/02-shared-app-account/sql/99_reset.sql
|
|
```
|
|
|
|
2. Create the table, data, and technical account:
|
|
|
|
```sql
|
|
@scenarios/02-shared-app-account/sql/00_schema.sql
|
|
@scenarios/02-shared-app-account/sql/01_seed_data.sql
|
|
@scenarios/02-shared-app-account/sql/02_identities.sql
|
|
```
|
|
|
|
3. Simulate an application or API using the `DDS_APP` account to query all orders:
|
|
|
|
```sql
|
|
@scenarios/02-shared-app-account/sql/04_test_queries.sql
|
|
```
|
|
|
|
## Expected Result Before
|
|
|
|
- The shared account can see orders from every seller and region.
|
|
- Fields such as `MARGIN` may be exposed if the application generates incorrect SQL.
|
|
- A bug, prompt injection, or abused endpoint may query more data than the user should see.
|
|
|
|
## After - Applying Deep Data Security
|
|
|
|
1. Apply data grants by business role:
|
|
|
|
```sql
|
|
@scenarios/02-shared-app-account/sql/03_data_grants.sql
|
|
```
|
|
|
|
2. Run the same query in the context of `alice` and `bruno`:
|
|
|
|
```sql
|
|
@scenarios/02-shared-app-account/sql/04_test_queries.sql
|
|
```
|
|
|
|
## Expected Result After
|
|
|
|
- `alice` sees only her orders and does not see `margin`.
|
|
- `bruno` sees LATAM orders with full manager visibility.
|
|
- The technical account is no longer the only security boundary.
|
|
|
|
## Demo Evidence
|
|
|
|
- Before/after comparison of the same SQL.
|
|
- Explanation of data roles.
|
|
- Simple flow: end user -> app -> database -> data grants.
