Best Practice Auditd Configuration
Idea
The idea of this auditd configuration is to provide a basic configuration that
- works out-of-the-box on all major Linux distributions
- fits most use cases
- produces a reasonable amount of log data
- covers security relevant activity
- is easy to read (different sections, many comments)
Sources
The configuration is based on the following sources
Gov.uk auditd rules alphagov/puppet-auditd#1
CentOS 7 hardening https://highon.coffee/blog/security-harden-centos-7/#auditd---audit-daemon
Linux audit repo https://github.com/linux-audit/audit-userspace/tree/master/rules
Auditd high performance linux auditing https://linux-audit.com/tuning-auditd-high-performance-linux-auditing/
Further rules
Not all of these rules have been included.
For PCI DSS compliance see: https://github.com/linux-audit/audit-userspace/blob/master/rules/30-pci-dss-v31.rules
For NISPOM compliance see: https://github.com/linux-audit/audit-userspace/blob/master/rules/30-nispom.rules
Video Explanations by IppSec
IppSec captured a video that explains how to detect the exploitation of the OMIGOD vulnerability using auditd. In that video, he walks you through the audit configuration maintained in this repo and explains how to use it. I highly recommend this video to get a better understanding of what is happening in the config.
