| Description |
|---|
| Service names may be discovered by unauthenticated users. If the service name includes version numbers or other database product information, a malicious user may use that information to develop a targeted attack. |
| ℹ️ Check |
|---|
| From SQL*Plus: select instance_name from v$instance; select version from v$instance; If the instance name returned references the Oracle release number, this is a finding. Numbers used that include version numbers by coincidence are not a finding. The database administrator (DBA) should be able to relate the significance of the presence of a digit in the SID. |
| ✔️ Fix |
|---|
| Follow the instructions in Oracle MetaLink Note 15390.1 (and related documents) to change the SID for the database without recreating the database to a value that does not identify the Oracle version. |
