Chapter 11 - Oracle Database Security
Protecting Data Requires
More than just Protecting the Production Database
Hackers often look for data in places that are left unsecured. The
listing below provides a few examples of the data stores that
hackers may access to steal your production data:
Oracle Export utility output files. Oracle
Export files can be easily transferred to a remote location and
quickly loaded into any Oracle database to recreate your production
database environment. The hacker then has unlimited access to all of
your trade secrets in complete anonymity and without maintaining a
connection to your production database.
The file copies from hot and cold database
backups. We (and the hackers) know that database backups are
duplicates of your production database. It is a often a simple
process for hackers to find the output files or find the scripts
that create the backups for your production database environment.
QA, test, development, reporting and disaster
recovery databases. How many times have you been asked to refresh
these non-production databases with production data? Once the data
is refreshed, these non-production databases must be treated as
production data stores and secured accordingly.
Using LOGMINER to scan Oracle online and
archived redo logs. Now that Oracle has provided us with a quick and
easy way to access data changes stored in the redo logs, these
files, and the LOGMINER utility, also needs to be secured.
The UTL_FILE_DIR directories. UTL_FILE_DIR is
used as the target directory for flat file output created from
PL/SQL stored programs. Hackers can gain access to the parameter
file that defines the output directory and gain access to the PL/SQL
output.
