Discussion

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.

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 DBA should be able to relate the significance of the presence of a digit in the SID.
