Onderwerp: Oracle Question Slightly OT

Forgive me for this being slightly off topic. We've checked Oracle's
site, including posting to their "Technology Network", and have yet to
find a best practices document for securing Oracle databases. Am I
missing something? ... Or should something this obvious be available on
Oracle's site? Can anyone provide links to such information?

Subject: Auditing Privilged Oracle Passwords - hashattack

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I've put together a tool that can be used to build a table of Oracle
password hashes from a dictionary file for a designated username.
Hashes are calculated by creating a user account similar to the target
account to be audited and repeatedly changing the password with "ALTER
USER" for each dictionary word, storing the hash for each password in a
table.

Once the table of hashes is built, a simple SELECT can be issued to
determine if the password hash for a target user is a simple dictionary
word:

SQL> select h.username, h.password, h.hash
2 from hashattack h, dba_users d
3 where d.password =3D h.hash and h.username =3D 'SYS';

USERNAME PASSWORD HASH
- ---------- -------------------- --------------------
SYS KILTPLEAT 2BBDC477FFB28563

Two excellent resources for securing Oracle databases includes the
Center for Internet Security benchmark (www.cisecurity.org) and the
"Securing Oracle: Step-by-Step" book at the SANS School Store
(https://store.sans.org/store_item.php?item=80).

Also, the SANS Institute recently started offering a 6-day class on
Securing Oracle database written by Oracle security expert Pete
Finnigan. More information is available at
http://www.sans.org/washington2005/d...n.php?tid=168.

I've also been very happy with "Oracle Security Handbook" by Theriault
and Newman (although a bit dated now) and "Effective Oracle Database 10g
Security by Design" by Knox (both published by Oracle Press).

NB: I work for the SANS Institute, and I am an instructor for the
Securing Oracle class.
