Securing AIX - Hardening Lesson 101

Every now and then I google: SecuringAIX (I write a blog by that name, so I am curious where it stands - and to my dismay I did not make the top5 today from my current location.

However, this unix.com/aix thread did make the top5- and, imho, it is lacking in clarity and ease. So, I thought I would post a refresher - AIX Hardening 101.

Since AIX 5.3, ML05 I believe (so we are anno 2005 I believe) - AIX intradiced a tool known as AIX Security Expert, or aixpert. This is meant to be pretty much - push button security - from it's start at least as much more has been added.

For a test drive - let it tell you what it finds wrong (note, wrong means different. If the level you choose thinks 4 is the right number and you have a different number (e.g., 3 or 5) it will say it is failed.).

So, test drive - no configuration changes made to your system with:

Code:

# [[ -e /etc/security/aixpert/core/appliedaixpert.xml ]] && mv /etc/security/aixpert/core/appliedaixpert.xml /etc/security/aixpert/core/appliedaixpert.xml.save
# aixpert -l high|medium|low|default|sox-cobit -n -o /etc/security/aixpert/core/appliedaixpert.xml
# aixpert -c
# [[ -e /etc/security/aixpert/core/appliedaixpert.xml.save ]] && mv  /etc/security/aixpert/core/appliedaixpert.xml.save  /etc/security/aixpert/core/appliedaixpert.xml
# more /etc/security/aixpert/check_report.txt

Note: you must choose a level to test against - one of high|medium|low|default|sox-cobit

This is part of bos.security.rte so it is always installed. Up to you to use it!

NAME

       secmod.db - Legacy NSS security modules database

DESCRIPTION

       secmod.db is an NSS security modules database.

       The security modules database is used to keep track of the NSS security modules. The NSS security modules export their services via the
       PKCS #11 API which NSS uses as its Services Provider Interface.

       The command line utility modutil is used for managing PKCS #11 module information both within secmod.db files and within hardware tokens.

       For new applications the recommended way of tracking security modules is via the pkcs11.txt configuration file used in conjunction the new
       sqlite-based shared database format for certificate and key databases.

FILES

       /etc/pki/nssdb/secmod.db
