Wondering if you’re doing everything possible to secure your Oracle database? You probably aren’t, but the Center for Internet Security has compiled a practical checklist which will get you damned close!

The Center for Internet Security (CIS) is a non-profit organization which is committed to providing information on best-practices for security. The CIS does not report every vulnerability in a piece of software, but rather provides a set of best-practices for setup and configuration of systems and applications to minimize security risks.

The CIS Oracle Benchmarks provide a wealth of information on installing and configuring Oracle. Far from a step-by-step on how to install Oracle, it does fill in many of the gaps that are easily overlooked.

The CIS approach is very practical. As an example, item 2.01 from the Oracle benchmark reads as follows:

Try to ensure that no other users are connected while installing Oracle 10g

The Oracle 10g installer application could potentially
create files in a temporary directory with public
privileges. It would be possible for any local user to
delete, overwrite or corrupt these files during the
installation process. Try to ensure that no other users
are connected while installing Oracle 10g. Also set the
$TMP and $TMPDIR environment variables to a
protected directory with access given only to the Oracle
software owner and the ORA_INSTALL group.

In this compressed format the Oracle 10g Benchmarks still span 55 pages; however, these 55 pages represent the equivalent of several years of experience.

While the complete list of benchmarks offered by the CIS is relatively small it hits the high points on enterprise level software. I expect in the long run the list will grow to include more of the open-source solutions we are now finding commonplace.

So grab your favorite sys-admin and a big cup of coffee and run through this checklist. You’ll be surprised what you find. If you happen to be the DBA _and_ the sys-admin you’d better make it an extra large coffee.
